The uterus is the place where the fetus is born, the channel for women's menstruation exclusion, and the channel for sperm to reach the fallopian tube. Therefore, female infertility factors mainly with the uterus, fallopian tubes, ovaries and so on.
Second: pelvic factors account for about 35% of the causes of infertility, including tubal abnormalities, chronic salpingitis, complete obstruction of fallopian tubes or hydrosalpinx leading to infertility. There are pelvic adhesion, pelvic inflammation, endometriosis, tuberculous pelvic inflammatory disease can lead to infertility.
Third: reproductive tract malformations, including uterine malformations, congenital tubal dysplasia, may cause infertility and abortion. There is ovulation disorder, accounting for 25% - 35%. The main reasons are persistent anovulation, polycystic ovary syndrome, premature ovarian failure and so on.

Some of the causes of ovulation disorders are persistent, while others are dynamic and cannot be defined as the only, absolute and persistent cause. For couples with menstrual cycle disorder, age 35 or older, and long-term unexplained infertility, the etiology of ovulation disorder should be considered first.
