1, tubal loss

(1) Unilateral fallopian tube loss and unicornuate uterus exist at the same time, which is caused by the failure to form Mullerian duct on one side in the early embryo.

(2) The oviduct may not be formed on the testes of true hermaphroditism. In the early stage of embryonic differentiation, the supporting cells of tissues are influenced by H-Y antigen (H-Y antigen translates as a histocompatibility antigen on the cell surface of male individuals), which produces anti-Mullerian duct factors, so that the ipsilateral Mullerian duct cannot form or inhibit its differentiation and development.

(3) Bilateral fallopian tube loss, mostly coexisting with congenital absence of uterus or only residual uterine malformation. Because the bilateral Mullerian duct is not formed or the development is blocked.

2. Tubal dysplasia

The fallopian tube is slender, the muscular layer is weak, the contractility is poor, and the delivery of sperm, eggs or fertilized eggs is slow, which is prone to infertility or ectopic pregnancy. A solid fallopian tube with partial fallopian tube loss or no lumen.

3. Double fallopian tubes or accessory fallopian tubes

Bilateral or unilateral double fallopian tubes may all open into the uterine cavity, or there may be a smaller and impassable uterine cavity called accessory fallopian tube, for unknown reasons. During embryonic development, the accessory mesonephric duct is punctured to form multiple fallopian tubes.

4. Fallopian tube diverticulum

Tubal diverticulum is more likely to occur in ampulla, and tubal pregnancy is easy to occur.

5. During the life of husband and wife, because women's uterine muscles will contract, some people will have obvious pain.

6, there will be pain in the lower abdomen, and 70% of patients have lower abdomen pain, which is also an obvious signal.

7. For many patients, dysmenorrhea will occur, and dysmenorrhea will continue to increase. Dysmenorrhea is the most obvious symptom of endometriosis, but it is also the most easily overlooked precursor. These ectopic endometrium are controlled by hormones and have periodic local bleeding, which leads to inflammation and pain in the surrounding tissues.

8, infertility, because chocolate cysts will affect ovarian function, about half of patients will have infertility problems after illness.
