Tubal Reversal Blog ‘pregnancy’

My name is Andrea, and I’m a 31 year-old home schooling mother to four children.

I’m married to my partner in Christ, Jeff, who is 36. Jeff has his own CPA practice here near our home. We live in beautiful Coeur d’ Alene Idaho, where we are a very close knit Christian family.

In 2005, against the advice of my doctor and with my husband cautioning against it, I had a Filshie clip tubal ligation at the planned c-section birth of my daughter. My doctor used clips because of my age at the time of tubal ligation, as well as the fact that he believed I would want more kids based on my nature.

Soon after the birth of my daughter, I began experiencing symptoms that independently wouldn’t have been alarming, but when gathered together, had me very worried and feeling terrible. Early after the birth, I felt very sad about not having more children. At times I thought the symptoms were just because I was sad about ending my fertility. Now I know they are separate, as well as the desire to continue to have more children, even if you already have “more than normal”, is a God given desire, and NOT something BAD.As my symptoms began to mount, I began a journal of NEW symptoms for me. While one or two of these may not be abnormal, each one of these was new for me, and together made a host of symptoms.

· Period returned 3 weeks after post-partum bleeding, despite breastfeeding full time.    The earliest I had a period while breastfeeding before was 8 months!

· Cyclical migraines or cluster headaches. Typically, one in the week before my period, one upon my period leaving, and one mid-cycle. Each took up to 4 days to clear completely, and each required prescription medication. Nausea and vomiting would accompany without treatment.

· First time I couldn’t lose my baby weight through breastfeeding, diet and exercise.

· Highly emotional, and easily brought to tears or sadness.

· Extremely dry skin.

· Mid-cycle cramping and breast tenderness.

· Terrible cramping for 1-2 days of menstruation, with moderate cramping before bleeding starts, with light cramping entire period. I’m a very active woman with high pain tolerance. This cramping was enough to nearly bring me to tears.

· Bleeding so severely, I would soak a pad in an hour. My doctor suspected menstrual anemia.

· Bleeding sometimes mid-cycle. Spotting would begin on CD 23-24 and continue through 28 when heavy period would start. Bleeding would last 7 full days, with spotting another 2-3 at the end.

· Persistent yeast infections, presumably from being “damp” due to having to wear pads much of the month to catch unexpected flow.

When looking at this journal, I sought the advice of my OB/Gyn and family physician. Both doctors acknowledged tubal ligation can and often does cause painful and heavy periods. However, my family physician went a step further. She conveyed that she had heard numerous cases of women having severe problems following tubal ligation, and was fully on board in my seeking a reversal. She did hormone screening and other blood work, and my OB/Gyn performed a pelvic ultrasound to rule out endometriosis, infections, fibroids, cancers and cysts. Both doctors gave me a clean bill of health, with no other cause for my new problems. Both doctors wrote to my insurance company, requesting payment for a tubal reversal on the sole basis of Post Tubal Ligation Syndrome (PTLS).

The insurance company, a national and well-known provider, wrote back these words:

“Although a tubal ligation reversal is medically necessary for the health of the insured, tubal reversals are not covered as the code falls under fertility treatment which is excluded. *Named insurance company* will authorize payment for treatments of hormone therapy, ablation, D&C and hysterectomy.”

Obviously, at 29 years old and also seriously mourning the loss of my fertility, these were not acceptable treatments for the physical manifestations of my tubal ligation.

We began the process of searching out the best doctor to perform a tubal ligation reversal, and saving the funds to do so. Some local physician’s, including my own, perform tubal ligation reversal. However, I was unable to feel satisfied about the outcome since none maintained accurate PTLS relief and pregnancy statistics based on their own work. Doctor’s in the Seattle area also do tubal ligation reversal, as well as many other cities in the nation. The local doctor’s were going to cost us about $12,000. Even with travel from Northern Idaho, Chapel Hill Tubal Reversal Center was a more affordable, and a more highly skilled facility.

Post Tubal Ligation Syndrome Series

This is the ninth article in our fourteen part series on PTLS and associated medical conditions. The first article, Pain After Tubes Tied: A Symptom of Post Tubal Ligation Syndrome?, introduces the most common symptoms some women attribute to their tubal ligation.

Readers can also read Andrea’s after surgery follow-up story: Andrea After Tubal Ligation Reversal Surgery. In addition to telling us how she has done after her tubal ligation reversal, she also has some exciting news to share!

Our next several articles will present personal stories of some of our patients who have suffered from worsening menstrual, physical, and emotional symptoms after surgical sterilization procedures ( women who had their tubes tied).

We invite readers to join our Tubal Reversal Message board and discuss and share personal experiences with tubal ligation. We also have a dedicated PTLS forum for readers to share experiences of worsening symptoms after tubal ligation procedures.

Is it PTLS or another medical or gynecologic problem?

The symptoms of Post Tubal Ligation Syndrome (PTLS) can be widespread and pervasive. Women who have problems after a tubal ligation, however, may not have PTLS. Another medical or gynecological condition may be at the root of the symptoms. The prior article in this series on PTLS reviewed medical and gynecologic disorders that may cause menstrual problems after a tubal ligation.

Over 7,000 tubal ligation reversals have been performed at Chapel Hill Tubal Reversal Center. We have had the opportunity to see the impact on these women whose tubes have been tied and who, having regretted that decision, have had their tubes untied.

Under what circumstances were the tubes tied?

Often, the decision to have a one’s tubes tied is made under stressful circumstances. Sometimes the decision to have the tubes untied is made under similar circumstances. The staff of Chapel Hill Tubal Reversal Center has compiled a list of stressful reasons women have had tubal ligations or have come to us seeking ligation reversal. Stressful circumstances under which patients sometimes have a sterilization procedure or a sterilization reversal include:

• Forced by parent or spouse
• Pressured by doctor
• Frightened by medical conditions or illness
• Mid-life crises
• Empty nest syndrome
• Infidelity
• Divorce
• Death of spouse
• Fear of birth control risks
• Decision while in poverty
• Decision during period of substance abuse
• Illness/death of close family member
• Sterilization while in an abusive relationship
• Death of a child
• Religious conversion

Regret and guilt can be powerful forces on any individual. Given the appropriate stressful circumstances these feelings can be amplified and can spread into other aspects of ones life. When decisions are made under stressful conditions, as listed above, one can easily see how this may leave a lasting sense of remorse upon any individual. The sense of remorse can be even more dramatic when the thought is suppressed and eventually emerges in the future during a stressful life event. Then consider the sense of regret and how these feeling could be increased as a person grows older and wiser when a person finds their ‘life’s match’ or if their pastor tells them they ‘violated the will of God’ by having their ‘tubes tied’.

How common is regret after tubal sterilization?

Most women do not regret their decision to have a tubal ligation. However, 1 out of 4 women will regret their decision about having their tubes tied. This was shown in the CREST Study mentioned in a previous article.

Offering Hope at Chapel Hill Tubal Reversal Center

The tubal ligation reversal experts at Chapel Hill Tubal Reversal Center help women in reversing these ‘permanent’ decisions when they are no longer the right decisions for individuals and couples. We have helped many patients come by restoring the hope of new life and the chance for some to relieve their burdens of guilt and regret.

This is the fourth article of a fourteen part series on PTLS and associated medical conditions. The fifth article, Psychological Conditions or Post Tubal Ligation Syndrome?, will address common psychological conditions that could be masquerading as Post Tubal Ligation Syndrome.

It is difficult to identify the first reported instance of a patient with Post Tubal Ligation syndrome (PTLS). The early literature from the 1950 – 1970’s has sporadic reports of patients who underwent tubal ligation and, subsequently, developed menstrual irregularities. In the mid – twentieth century, PTLS seems to have been discussed more that it was studied by the medical community.

Several medical studies from the 1980’s and 1990’s suggested there was no association with tubal ligation and menstral irregularities. These studies have been criticized because they involved a small number of patients, had methodological problems, and were not designed to critically evaluate for the existence of PTLS.

U.S. Collaborative Review of Sterilization Study

The most conclusive medical study to evaluate female sterilization and the effects upon American women was the U.S. Collaborative Review of Sterilization study. This study is commonly referred to as the CREST study. A synopsis of this study can be found on-line at the medical research organization Contraception Online.

The CREST study conducted by the Center for Disease Control and Preventions (CDC) and was published in the New England Journal of Medicine in 1996. To date, the CREST study has been the largest and most comprehensive evaluation of women who have undergone surgical sterilization in the United States. The study was primarily designed to evaluate the types of sterilization methods that were commonly being performed by U.S. doctors and the failure rates associated with each of the different methods of sterilization.

The study examined over 14,000 women who had tubal sterilizations (tubal ligation) from 1978 to 1986. Women were examined for up to 14 years after their sterilization procedures. The investigators specifically looked at the method of tubal ligation and failure rates (pregnancies) based on each method. They also examined the number of women who regretted their decision to undergo sterilization.

CREST  Findings

The main findings of the CREST study were that pregnancies after tubal ligation and sterilization regret were both more frequent than had been previously thought.

Women were also asked questions about changes in their menstral patterns after tubal ligation. The study compared 9514 women who underwent tubal ligation to 573 women whose partners underwent vasectomy. The women were asked about changes in their menstral patterns for up to five years after sterilization. The women who underwent sterilization were found to have fewer irregularities with their menstral patterns. The authors’ conclusion was there were no significant differences in menstral patterns in women who had tubal sterilization. A commentary by the study investigators regarding these findings can be found at the National Institute of Health.

The existence of Post Tubal Ligation syndrome has been widely speculated by many but never substantiated in a rigorous fashion by medical investigators. Many poorly done small studies have suggested PTLS does exist; however, the largest study to date, the CREST study seems to suggest otherwise.

Limitations of the CREST Study

Although the CREST study has been the largest study with the longest follow-up of women who have undergone sterilization, some investigators have criticized the study.

The CREST study has limitations evaluating PTLS because of three reasons:

1. The study population is mostly from academic centers and is made up of a large number of African American women. This has led some cautious medical investigators to suggest the study has population bias and the findings of the study may not be applicable to the general population of United States women who undergo sterilization.

2. The study did not address the question whether women may develop menstral irregularities beyond five years after their tubal ligaiton. Most of the questions regarding menstrual irregularities were not asked after five years of follow-up.

3. The study was not designed to investigate the diverse symptoms of PTLS. The primary goal was to identify what the most popular methods of tubal ligation were and what the failure rates of each method were.

If PTLS does not exist then what is going on?

Many patients come to Chapel Hill Tubal Reversal Center requesting sterilization reversal for the sole purpose of treating symptoms they identify as PTLS. Many of these patients report substantial improvement in their symptoms after tubal ligation reversal. We are not certain why patients report improvement, but it is hard to ignore their reports of improvement in symptoms after ligation reversal surgery.

Most women who have tubal ligations will not have any problems. Some women will have difficulty after a tubal ligation. Many, or perhaps the majority of them will not have PTLS. Instead, they may have an underlying medical or gynecologic illness. To aid our patients in the evaluation of difficulties they may be having after a tubal ligation, our next article will have information for patients about abnormal bleeding, painful menstruation, and possible underlying causes.

This is the second article in a fourteen part series. Our third article in this series is Diagnosing Menstrual Problems After Tubal Ligation.

We periodically write case reports on patients who undergo tubal ligation reversal at Chapel Hill Tubal Reversal Center. The patient we will profile today had a ligation reversal procedure at our center last month.

She and her husband traveled to Chapel Hill from West Virginia. She is 34 years old and previously was an in-vitro fertilization (IVF) nurse. She is the mother of two children (ages 5 and 2). Her husband works as an engineer and is the father of both of their children. She had a tubal ligation after her second child because of two difficult, high-risk pregnancies.

Her first pregnancy was a vaginal birth complicated by heavy post-partum bleeding. Her heavy bleeding required a dilation and curettage (D and C) and emergency abdominal surgery to control the blood loss. She was diagnosed as having a placenta accreta. This is a condition where the placenta has invaded into the uterus too deeply and does not separate normally from the uterus at the time of delivery. She recovered from this surgery and eventually had a second pregnancy. This child was delivered by C-section and she had a Pomeroy tubal ligation done during the C-section. The operative report described tying and cutting the tubes as well as burning the ends. The pathology report described 1.5 cm tubal segments as being removed.

She explained to us, “My decision to have a tubal ligation was not done prayerfully but was more of a medically made decision.” She and her husband now desire more children in their life, and they traveled to Chapel Hill Tubal Reversal Center to have her tubal ligation reversed.

We were concerned that her doctor described in the operative report the tubal cauterization (burning) after tying and cutting the tubes. Since the mention of the cauterization was vague (we had no idea if a small segment was burned or the entire tube was burned) we discussed starting with a screening laparoscopy. Our patient was able to talk to her doctor who performed the tubal ligation. The doctor assured her only the ends of the tubes were burned. Since this can be a common practice and seemed minimal, the decision was made to proceed with ligation reversal without starting with a screening laparoscopy.

During her operation we found the right fallopian tube was abnormal. The right tube was long and healthy appearing, but there was no fimbriated end of the tube. This area is one of the most critical areas of the tube. The fimbriated ends act like millions of small fingers, which pick up the egg and direct the egg down the tube. The repair of this tube would require a more difficult microsurgical salpingostomy and creation of a ‘neo-fimbriated’ end of tube.

A microsurgical salpingosotomy was performed on her right tube. The left side was more normal- we had two tubal segments that we repaired with the usual anastomosis procedure. The entire operation was about one hour and fifteen minutes.

The story of this patient illustrates several important concepts:

1. She was a knowledgeable medical professional. She understood what it meant to have a tubal ligation. Many patients of all walks of life will have changes of heart as their lives change. Even medical professionals will make health care decisions for themselves, which later turn out to not be right for them. None of us can predict the future.

2. She was an IVF nurse and was aware of the pros and cons of tubal ligation reversal vs IVF. She and her husband decided ligation reversal was a more appropriate path for them.

3. Operative and pathology reports provide helpful information in planning for tubal repair, but they can sometimes be misleading.

4. The right tube was very difficult to repair. Often we will question ourselves as to whether a difficult tube should be repaired or should we just focus on the ‘better’ tube. We can never predict with 100% certain what will or will not work to help get a patient pregnant, so we like to give all patients the benefit of the doubt and try at all costs to open all the tubes we operate on.

We wish her and her husband a successful outcome of her tubal reversal operation and hope their prayerful decision will be soon rewarded.

Tubal reversal information is plentiful on the internet, but not everything that you read is accurate or factual. Of the websites that provide information about tubal ligation reversal, the one from Chapel Hill Tubal Reversal Center is most complete and accurate. It describes the various types of tubal ligation procedures and the different tubal reversal procedures that can be used. If you are interested in learning about tubal reversal, spend some time looking at the different pages on this extensive site. There is a search box at the top of every page that can direct you to specific information about any issues relating to tubal ligation reversal. Take a look also through the many topics of information on the Tubal Reversal Blog.

Tubal Reversal Surgery

Tubal ligation reversal is usually considered to be a major operation, taking several hours and requiring a hospital stay of 1 to 5 days. Complete recovery is often described as taking 4 to 6 weeks. However, the tubal reversal procedure that Dr. Berger has developed is performed as outpatient surgery with no hospital stay required and with complete recovery generally within 5 to 10 days. Since hospitalization is not required, the cost of the tubal reversal procedure is reduced by half or two-thirds of the cost when performed in a hospital. Patients are more comfortable during their post operative recovery and are able to return to work and other normal activities much faster. A free video or DVD of Dr. Berger’s tubal reversal procedure is available on the Chapel Hill Tubal Reversal Center website.

Risks of Tubal Reversal

As with any surgery, complications are always a possibility. Although rare, these may include bleeding, infection, damage to other organs, or complications of anesthesia. The most significant risk associated with tubal ligation reversal is the long term risk of having an ectopic pregnancy. This risk is increased from approximately 2% of pregnancies in the general population to approximately 10% after tubal reversal. Fortunately, the medical problem of a ruptured tubal pregnancy can be prevented by following an early pregnancy monitoring protocol that has been described by Dr. Berger and is recommended to all women after a tubal reversal procedure.

Alternative Treatment

Rather than “untying” their tubes, some women are advised to be treated by in vitro fertilization (IVF). However, IVF is more complicated and expensive, the pregnancy rate after IVF is not as high as after tubal reversal, and there is a very high incidence of multiple births (approximately 30%) after IVF. Further, there is concern about the possible long term effect of the use of potent hormones to stimulate the ovaries to produce many eggs (called “super-ovulation”) and the suspicion that it might increase the risk of ovarian cancer later in life.

Am I a Candidate for Tubal Reversal?

Although most women have been told that tubal ligation is permanent, in fact, the vast majority of tubal ligation procedures are reversible. The operative report from your tubal ligation will give a good indication if the procedure can be reversed. When there is any doubt about this, diagnostic laparoscopy can be performed to examine the fallopian tubes and then decide whether to proceed with the reversal operation.

Pregnancy Rates After Tubal Reversal

Pregnancy and birth rates after a tubal reversal are significantly better than after IVF. Neither procedure, however, can guarantee that pregnancy leading to birth will occur. Even when the fallopian tubes have been repaired, other factors – such as age, menstrual cycle regularity, ovulation or other hormonal disorders, and the fertility of the male partner – may determine when, or whether, conception will occur.

Women under the age of 30 who have a tubal reversal have an 82% pregnancy success rate; between 30-34 the pregnancy rate is 76% and for women ages 35-39, the pregnancy rate is 67%. The pregnancy rate declines for women 40 and older in accordance with the natural decline in fertility with age. However, pregnancy rates are higher for women of any age following tubal reversal than after IVF.

The experienced nurses at Chapel Hill Tubal Reversal Center are always happy to provide information about tubal ligation reversal. You can also exchange information with other women on the Tubal Reversal Message Board.

Tubal Ligation by Coagulation or Cauterization

Bipolar tubal coagulation is a popular method of female sterilization in the United States. This tubal ligation method is usually performed through laparoscopy. With the bipolar (two-poles) coagulator, the fallopian tube is grasped between two poles of electrical conducting forceps and electrical current is passed through the tube between the two ends of the forceps. Damage to the tube is limited mainly to the small segment between the forceps. Burning two or three adjacent sites is common and generally results in the loss of a few centimeters of the fallopian tube. Bipolar tubal cauterization can be successfully reversed in almost all cases.

Monopolar tubal coagulation is less common than bipolar coagulation tubal ligation. With monopolar forceps, electrical current spreads further along the length of the fallopian tube. Consequently, monopolar cautery tends to damage more of the fallopian tube than bipolar cautery. In many cases, the tube is also cut after it has been coagulated.

When monopolar coagulation is applied to a single site of the tube, tubal reversal can be performed without the need for further diagnostic tests. If multiple sites of the fallopian tube have been burned with the monopolar technique, we offer a screening diagnostic laparoscopy to evaluate the tubal lengths before proceeding to reparative surgery. The screening laparoscopy option is discussed further on our website.

Tubal Coagulation Reversal Success

Each year Chapel Hill Tubal Reversal Center publishes updated statistics about pregnancy rates and pregnancy outcomes among all of the women who have had tubal reversal procedures performed by Dr. Berger. The data for women who had tubal coagulation sterilizations, presented in the table below, are from our Tubal Reversal Pregnancy Study Report 2007.

Pregnancy Rates of Our Tubal Reversal Patients

The overall pregnancy rate after tubal reversal for women with tubal coagulation procedures is 68% for patients at Chapel Hill Tubal Reversal Center. To calculate the pregnancy rate, the number of women who have become pregnant is divided by the total number who underwent a tubal reversal procedure. The following table shows the numbers and pregnancy rates according to womens’ ages at the time of their tubal reversal surgery.

Pregnancy Rates After Tubal Coagulation Reversal

Conclusion

Tubal coagulation methods of tubal ligation can be successfully reversed in most cases. The pregnancy rate after tubal reversal varies with a woman’s age at the time she has her tubal reversal procedure. The pregnancy rate is 85% for women in their twenties, 74% for those ages 30-34, 64% for women in the 35-39 year age group, and 35% for women 40 years of age or older.

Our Tubal Reversal Center is Unique

Dr. Berger is the only physician in the country with a practice that is specifically limited to tubal reversal surgery. That is the only procedure performed here with Dr. Berger performing four reversals each day, five days a week. We have a high staff/patient ratio with one or two nurses devoted specifically to your care while you are here. All of our nurses have advanced certification in cardiac life support (ACLS) and our anesthesiologists are MDs with board certification in anesthesiology. The anesthesiologists are employees here and not anesthesia staff from another hospital or anesthesia service. In other words, everyone at Chapel Hill Tubal Reversal Center has expertise in caring for tubal reversal patients and performing reversal surgery. While you are here, you will only be with other women and couples who are here specifically for the same purpose.

We Provide Accurate Tubal Reversal Statistics

We keep detailed data and statistics on each of our patients (such as age, tube length, medical history, tube of tubal ligation, pregnancy history). This is obtained by ongoing contact with our patients to ensure we have accurate information regarding their surgery and their outcome. Dr. Berger maintains and publishes data regarding pregnancy rates and pregnancy outcomes following tubal reversal surgery. We know of no other doctor or medical facility that does this.

On the Internet, claims about tubal reversal pregnancy rates are often made without supporting information or documentation – such as a description of the patient population, study method, and follow-up interval. Most Internet sites about tubal reversal do not provide any factual data at all. Any doctor may say that his patients have a particular success rate, but supporting the claim with actual data involves considerable effort. Performing a follow-up study such as this one requires keeping an accurate record of patients and their findings, as well as maintaining ongoing patient contact to determine the outcomes of treatment. That is the only way a doctor can actually know what the pregnancy and outcome statistics are for his patients. Without this detailed type of information, the accuracy of any claim of success rates should be questioned.

At Chapel Hill Tubal Reversal Center, nurses enter information into an electronic patient database at the patient’s registration, the surgical procedure, and from regular post-operative communications with our staff. If we have not heard from patients after their recovery from surgery, our nurses contact them at 6 and 12-month intervals. We know of no other doctor, hospital, or clinic that maintains such ongoing patient follow-up records after tubal reversal surgeries. I believe Dr. Berger’s commitment to providing accurate, up-to-date data is reflected in the fact that he requires this time-consuming but important procedure to be followed so that valid information can be obtained. Each year we publish the results of our follow-up study, reflecting surgical and pregnancy outcomes. This is the most comprehensive study done to date of tubal reversal surgery and its resulting outcomes, showing that for the majority of women who have undergone a tubal ligation procedure and decide later they would like to have more children, tubal reversal surgery is a better option than in vitro fertilization (IVF).

We Follow-up With Patients and Are Always Available

Another reason to choose Dr. Berger and Chapel Hill Tubal Reversal Center is the staff! We are available 24 hours a day/7 days a week to answer questions and concerns. Patients regularly express amazement at the level of care, compassion, and professionalism that they were shown before, during, and after surgery. Patients also like the fact that they receive follow-up calls on post-op day 1 and 3 and at 2 weeks, simply to see how they were doing and to have any questions answered. Our nurses follow-up with each patient again at 6 months and one year after surgery.

The fallopian tube is an amazing and versatile reproductive organ. Its functions include capturing an egg from the ovary at the time of ovulation; nourishing the fertilized egg or zygote during its early cell divisions; and delivering the blastocyst into the uterine cavity when it is time for implantation. The different parts of the fallopian tube correspond to these various functions.

Tubal Anatomy

The end of the tube furthest from the uterus is the fimbria. The fimbrial segment is lush with cilia that beat vigorously and sweep the egg into the tube where it is fertilized. The egg is quickly moved by the bell-shaped infundibular segment into the ampullary region of the tube. Over the next several days, the combination of muscular contractions and ciliary movement move the egg toward the uterus. The ampulla provides nourishing fluid that allows repeated cell divisions. When the dividing egg (zygote) reaches the stage where the outer membrane dissolves (blastocyst), it is time to be delivered into the uterine cavity. This is the function of the muscular isthmic segment of tube closest to the uterus.

Does Anatomy Predict Function After Tubal Reversal?

Given the complexity of the functions of the fallopian tube, one might wonder if any portion is essential for pregnancy to occur. Years ago, based on the information available in medical texts, I assumed that there would be essential parts or a minimum length of tube needed to result in a normal pregnancy. However, there was little information available to answer this question. Therefore, I began recording the portions of tube removed, tubal segment lengths remaining, and other details about each patient’s reversal operation in an electronic database. Since the staff members at Chapel Hill Tubal Reversal Center follow-up with patients regarding pregnancy after tubal reversal, it has become possible to study the interaction of tubal anatomy and the tube’s ability to function normally.

A Surprising Discovery

Over the 30 years that I have been performing tubal reversal procedures, I have seen every variation of tubal ligation imaginable regarding the sections of tubes removed and lengths of tube remaining to repair. It was surprising to learn that no specific part of the fallopian tube is absolutely required for pregnancy to occur. Somehow, the fallopian is able to compensate for the loss of specific parts and still function normally! Based on this knowledge, I am optimistic in being able to repair any kind of tubal sterilization procedure with the expectation that it will allow the possibility of having more children.
