Fallopian tube blockage IVF success rate Can IVF be done if fallopian tube is blocked?

Blocked fallopian tubes can cause infertility, so if a woman has blocked fallopian tubes, can she not be a mother? The answer is no. Patients with blocked fallopian tubes can get pregnant through test tubes. Today, let's talk about the precautions for women with blocked fallopian tubes to do test tube babies.

Why does blocked fallopian tubes cause infertility?

Some patients ask why blocked fallopian tubes can cause infertility? We know that women must have four major elements to get pregnant: sperm, egg, fallopian tube, and uterus. The role of sperm and egg is self-evident, but you may not know that the place where sperm and egg meet is the fallopian tube. The fallopian tube is like the magpie bridge where sperm and egg meet. If the fallopian tube is blocked, it means that the Cowherd (sperm) and the Weaver Girl (egg) cannot meet, and it is impossible to form an embryo forever, thus leading to infertility.

The proportion of those who choose IVF due to infertility caused by fallopian tube obstruction accounts for the majority of all IVF. It can be said that IVF is actually a technology designed for patients with fallopian tube obstruction.

Factors that affect the success rate of IVF

What factors may affect the success rate of IVF?

① The technical level of doctors and medical institutions. Experienced doctors can master every aspect of patient treatment and adjust the treatment plan in a timely manner according to the patient's condition.

② The patient's ovarian function. The older the age, the worse the ovarian function and the lower the egg quality, which will also affect the success rate of IVF.

③ Sperm quality. Nowadays, men have great work pressure, coupled with some unhealthy lifestyles, which can cause unhealthy sperm.

④ The environment of the endometrium. We compare the embryo to a seed, and the endometrium is the soil where the seed grows. No matter how good the seed is, it will not grow crops if it grows on concrete. Therefore, it is necessary to adjust the uterine environment in advance, remove adverse causes, and prepare for embryo implantation.

Fallopian tube obstruction: preparations to be made before IVF

Patients with hydrosalpinx must undergo surgery before IVF

For patients with blocked fallopian tubes, even if they have decided to have IVF, they cannot ignore all fallopian tube problems. Especially for patients with hydrosalpinx, they must undergo surgery before doing IVF. Why? First of all, because hydrosalpinx is caused by inflammation, and the fallopian tube is connected to the uterine cavity, once the hydrosalpinx enters the uterine cavity, it will bring in a large amount of inflammatory substances, which will affect the implantation of the embryo. Not only that, the hydrosalpinx entering the uterine cavity may also wash away the embryo.

Therefore, for patients with hydrosalpinx, doctors will recommend ligation or removal of the fallopian tubes before IVF. This is because the blood supply of the fallopian tubes and ovaries comes from the same artery, and the return is also from the same vein. During the operation, the doctor will carefully separate the blood vessels, try not to damage the blood supply of the ovaries, and try not to affect their function. However, we know that everyone's blood supply is different, and doctors cannot guarantee that every operation will not affect ovarian function. Therefore, after the fallopian tube surgery, you must seize the opportunity and enter the IVF cycle as soon as possible.

Eliminate all influencing factors and strive for success at one time

Then the next question is how to eliminate the factors mentioned above that affect the success rate of IVF. We will evaluate the physical condition and reproductive function of both men and women, solve the problems if there are any, and then enter the IVF cycle to strive for success at the first try. Below we briefly introduce how to conduct the evaluation.

Ovarian function tests: Ovarian function tests generally include the following types.

① Six hormone tests: fasting blood test on the morning of the 3rd to 5th day after menstruation. The purpose is to detect six indicators: follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), progesterone (P), testosterone (T), and prolactin (PRL) to understand the female endocrine function;

② Antral follicle count: The number of basal antral follicles (antral follicles are the morphology before the appearance of mature follicles, and normal women can have 6 to 10 antral follicles per month) is observed by ultrasound to evaluate ovarian function;

③ Anti-Mullerian hormone (AMH) test: AMH is a hormone secreted by the granulosa cells of the ovarian follicles. Female babies start to produce AMH from 9 months of age. The more follicles there are in the ovaries, the higher the concentration of AMH. Conversely, when the follicles are gradually consumed with age and various factors, the AMH concentration will also decrease. Combining the results of these tests, the doctor will have a clear idea of ​​the patient's ovarian function.

Sperm examination: We cannot ignore male factors in fertility. Don't wait until you find that the quality of the cultivated embryos is not good before going back to check the man. Sperm examination is generally done at least twice. If it is abnormal, or the difference between the two times is large, it will be checked for the third time. The examination includes: chromosome examination, seminal plasma biochemical examination, sperm fertilization ability, etc. It is also necessary to pay attention to whether the man has other conditions that affect the quality of the embryo, such as bilateral varicocele, very unhealthy lifestyle, excessive obesity, and a history of diabetes and hypertension, which may affect the quality of the embryo. Therefore, we recommend that these men undergo adjustment treatment before undergoing IVF. Patients with severe oligoasthenospermia are more difficult to treat, but because one sperm is enough for one egg, so after a certain treatment, as long as healthy sperm appears, we can enter the IVF cycle.

What to do if the fallopian tube is blocked

Women with blocked fallopian tubes should pay attention to the following 5 points:

1. Avoid injuries caused by abortion

Artificial abortion can cause serious damage to the uterus and fallopian tubes, and induce fallopian tube blockage. After abortion, the endometrium will be weakened and thinned, and at this time the endometrium is very susceptible to bacteria and microorganisms, causing pelvic inflammatory disease, urethritis, endometritis, and then causing fallopian tube blockage.

2. Keep clean and hygienic

To prevent fallopian tube blockage, the prerequisite is to pay attention to your own cleanliness and hygiene, clean your genitals every day, change your underwear, towels, washbasins, etc. frequently, and keep them separate from others, otherwise it is easy to cause cross-infection among multiple people.

3. Reasonable combination of diet and daily life

Bad living and eating habits may lead to fallopian tube blockage. Eating more healthy green fruits and vegetables and drinking some green tea can effectively help wash away the fat in the body. In addition, maintaining normal rest time and moderate exercise can help improve fallopian tube blockage.

4. Sexual life should be moderate

Sexual intercourse is a major cause of female fallopian tube blockage. It is easy to bring foreign bacteria and viruses into the female vagina during sexual intercourse, causing fallopian tube blockage. Experts recommend that men and women should wash thoroughly and maintain hygiene before having sex, so that sexual intercourse can maintain the best quality and prevent fallopian tube blockage.
