Are women with endometriosis prone to infertility? These 7 types of women should be cautious of infertility and come to their doorstep

Male factors account for about 40% of infertility, female factors account for about 40%, and causal infertility accounts for about 20%. In female infertility, fallopian tube factors account for about 40%, ovulation factors account for about 40%, unexplained factors account for about 10%, and the other 10% are uncommon factors.

The main reasons for female infertility are as follows:

1. Infection: Most fallopian tube diseases are secondary to infection, especially pelvic inflammatory disease (PID). Other causes include appendiceal perforation, post abortion infection, etc. Adhesion can lead to occlusion of the fallopian tubes. Research shows that the incidence of acute PID in women aged 15-19 is approximately 10-13 out of every 1000 people, while it increases to 20 out of every 1000 people aged 20-24. The high incidence of sexually transmitted diseases (STIS) is also an important reason for the increase of artificial intelligence incidence rate, such as chlamydia infection. In addition, appendix perforation is an important factor leading to tubal infertility, and infectious abortion is another major risk factor for tubal infertility.

2. Endometriosis: There is currently controversy over whether potential small or mild endometriosis (stage 1 or stage 2) can cause infertility, possibly due to pelvic adhesions and inflammatory factors leading to low fertility, while stage 3 or stage 4 endometriosis, due to severe pelvic adhesions, can cause distortion of the fallopian tubes and ovulation dysfunction, leading to infertility.

3. Adhesion after surgery: Adhesion can affect pregnancy rate. If there is no pregnancy after 1 year of fallopian tube recanalization surgery or if serious diseases are found during the surgery, in vitro embryo transfer (IVF-ET) may be the only option.

4. Reproductive tract malformations: the incidence rate of uterine malformations in pregnant women is 1:594, and that in non pregnant women is 1:28. The results showed that the incidence rate of congenital uterine malformations in non pregnant women was 21 times higher than that in normal women. Among uterine malformations, 7% were saddle shaped uterus, 34% were uterine septum, 39% were bicorned uterus, 11% were bicorned uterus, and 5% were monocorned uterus. The saddle shaped uterus and double uterus have no significant impact on infertility, the pregnancy loss rate of patients with incomplete uterine septum is significantly increased, and the infertility rate of single horn uterus is significantly increased.

5. Exposure to diethylstilbestrol (DES) is closely related to uterine malformations, such as short curved ducts and small opening wrinkles at the umbrella end. Nodular isthmic salpingitis indicates that the mucosa of the isthmic fallopian tubes expands to the muscular layer and serosa. There is conflicting evidence between congenital and infectious rest rooms, but it is clearly closely related to infertility and ectopic pregnancy. Other deformities such as the opening of the accessory fallopian tubes and the long ciliated fallopian tube syndrome are also closely related to infertility.
