Many women who have had a tubal ligation, commonly referred to as “having your tubes tied,” find themselves wanting another child due to life changes. But can a woman get pregnant if she’s had a procedure that is considered a permanent form of birth control? Yes, and talking to a reproductive endocrinologist is the first step in determining all of the options.
Dr. Jason Bromer, of Shady Grove Fertility’s Frederick office, says, “women with tubal ligations are some of our most successful patients because we know that they have been fertile before. There are two ways pregnancy can be achieved after tubal ligation. Traditionally, the only option for patients was through a surgery called a tubal reversal. However, there is now another option for women with In Vitro Fertilization, or IVF.”
In almost every case, IVF is the better option because it gives patients the highest chance of pregnancy in the shortest amount of time, and avoids a significant surgical procedure.
Tubal Reversal Surgery
Tubal ligation can be performed in a number of different ways but the result is always the same – an interruption of thefallopian tubes that prevents pregnancy. “The most common method of tubal ligation is the surgical removal of the middle section of the tubes,” says Dr. Bromer. “So the goal in a tubal reversal surgery is to reconnect the tubes to make them open all the way through.”
The latest methods for performing a tubal reversal surgery require only one day for the procedure and seven days of light bed-rest following it. About three months after the surgery, patients have a Hysterosalpingogram (HSG) to check the status of the tubes. An HSG is a diagnostic test using x-ray technology to show the flow of dye through the uterus and fallopian tubes into the uterine cavity. It shows if there are any blockages remaining in the tubes that might prevent pregnancy.
Tubal Reversal Success and Increased Risks
Whether or not tubal reversal surgery can be successfully performed depends on two factors. “Is there enough healthy tissue on each end of the tube to be reconnected,” explains Dr. Bromer, “and is the reconnected tube long enough to function properly? Unfortunately, not all patients have tubes that can be reconnected.”
“Sometimes even when reattaching the tubes is successful, there can be scarring of the tissue that interrupts the flow of the tube,” says Dr. Bromer. “This happens in about 20% of the cases.” If, however, the HSG confirms that the tubes are open, then the patient can begin trying to get pregnant on her next cycle.
There is also an increased risk for ectopic pregnancy after tubal reversal surgery.
“One risk with tubal reversals is that there is a 10-20% chance of having an ectopic pregnancy after tubal reversal surgery,” says Dr. Bromer. Ectopic pregnancy occurs when a fertilized egg gets stuck in the fallopian tubes and implants there. Ectopic pregnancies must be terminated with medications or surgery to avoid a rupture of the fallopian tube, which can be life-threatening.
Since the tubes cannot always be reconnected, the success rate for achieving pregnancy after a tubal reversal is around 40% for women under 37.
IVF and Success Rates
Another popular option for women trying to get pregnant after a tubal ligation is In Vitro Fertilization or IVF. IVF is a process by which an egg is fertilized in the lab and then transferred to a woman’s uterus. This allows for pregnancy to occur by completely bypassing the fallopian tubes.
Any woman who has a good ovarian reserve or has previously attempted a tubal reversal unsuccessfully would be a good candidate for IVF treatment. Dr. Bromer adds, “Even couples with fertility challenges other than the tubal ligation, such as advanced age or male factor infertility, can be helped by IVF.”
An IVF cycle takes about two months to complete. After the evaluation and hormone suppression phase of the cycle, patients are prescribed injectable hormones that stimulate egg maturation. During this 10-12 day stimulation period, the patient is seen frequently for ultrasound and bloodwork to monitor the growth of egg containing follicles and the levels of hormones.
At the end of this period, an egg retrieval procedure is performed. The eggs are fertilized with the partner’s sperm and grown to three or five day embryos. Then, one or more embryos are transferred to the woman’s uterus. Two weeks later, a blood pregnancy test reveals the results.
The success rate for achieving pregnancy with IVF frequently exceeds that of a tubal ligation. At Shady Grove Fertility, IVF has a 50-60% success rate for women under 38, even when only one embryo is transferred.
Time to Pregnancy
It takes about three months after a tubal reversal surgery to confirm that the surgery was a success. Once the tubes are shown to be clear by the HSG test, the average time to pregnancy, from start to finish, is two years.
“The fact that it can take up to two years to become pregnant after tubal reversal surgery is really off-putting to a lot of my patients,” says Dr. Bromer. “Most of them are anxious to get pregnant sooner, often because they are older when they start the process.”
“One of the best things about IVF is that the time to pregnancy is so much shorter,” says Dr. Bromer. A cycle of IVF takes only about two months to complete. Some women require multiple rounds of IVF to achieve pregnancy, but even with difficult cases, treatment is usually completed within a year.
Age is a key factor in the decision between IVF and tubal reversal surgery. As a woman ages, the number and quality of her eggs decline, making it harder to get pregnant. As early as 30 years old, a woman’s chances of getting pregnant each month start to go down.
Since many women who want to get pregnant after tubal ligation are in their thirties, there is a chance that even with a successful tubal reversal surgery, they won’t become pregnant, as the 2 year time to achieve pregnancy becomes even more significant. In this case, it is likely that IVF would be recommended. To avoid having to do surgery and IVF, it is recommended that these women choose IVF as the first line of treatment.
“For women over 37, I wouldn’t even consider tubal reversal surgery,” says Dr. Bromer. “In this age group, where declining fertility is coupled with a higher risk of ectopic pregnancy, IVF is clearly a safer option with better chances of success.”
Tubal reversal surgery and one cycle of IVF cost about the same amount, between ten and fifteen thousand dollars. Tubal reversal surgery is almost never covered by insurance.
Shady Grove Fertility has several innovative financial programs that reduce the cost and financial risk associated with treatment. These programs include a Shared Risk 100% Refund Plan, Multi-Cycle Discount Program, Shared Help Fertility Treatment Discount Program and options for grants and loans for fertility treatment.
The most popular program is the Shared Risk 100% Refund Plan. This plan entitles the patient to up to six rounds of IVF and the related frozen embryo cycles. If the patient does not take a baby home, 100% of the fee is refunded.
“With the Shared Risk program and the success rates being so high at Shady Grove Fertility,” says Dr. Bromer, “IVF is almost always the more cost-effective option.”
Male Partner’s Fertility
One more factor that can tip the scales is the male side of the equation. Having a sperm analysis completed for the male partner is a critical step in making the decision about whether to use IVF or tubal reversal surgery. “If the male partner of the couple has a low sperm count for example,” explains Dr. Bromer, “then even a successful tubal reversal surgery is not likely to result in pregnancy.”
IVF, however, can be performed with special techniques that work around the male factor issues. ICSI, for example, is a process in which a single healthy sperm is injected into the center of each egg resulting in normal rates of fertilization even in men with severely abnormal sperm counts.
The Prognosis is Good
Dr. Bromer says the key to this decision is a thorough evaluation and a discussion of the patient’s goals. “I suggest that couples come in and bring all the paperwork about their tubal ligation surgery,” he says. “We will do some basic fertility testing on both partners and go from there – but the first step is making an appointment.”
For some women, the answer will be tubal reversal surgery. “The ideal candidate for tubal reversal surgery is a woman under 35, who wants multiple additional children and who had a well-performed tubal ligation.” Dr. Bromer says.
“The majority of my patients, however, have had multiple children, but later divorced and remarried. They are usually over 35 by the time they come in and want to have only one more child with their new spouse. For these women, IVF is nearly always a much better option.”
Either way, the prognosis is good. With a little expert guidance, women with tubal ligations can be back to changing diapers in no time.
