Ovulation problems, anovulation (not ovulating) cause menstrual irregularities, usually delays in menstruation, and they constitute about 25% of the causes of infertility. Women with hormonal irregularities and women with metabolic and hormonal problems such as polycytic ovary syndrome are faced with infertility problems due to not ovulating.
Ovulation is defined as the release of a mature egg from the ovaries every month in order for pregnancy to occur, it coincides with the 14th day of menstruation, and the most suitable days for pregnancy are the days close to the ovulation day (days 12-14-16 of the menstruation).
INFERTILITY DUE TO TUBE
In order for the egg released from the ovary to be caught and combined with the sperm in a healthy way, for the pregnancy to occur and settle in the uterus, the tubes (tuba) must be open and healthy.
In women, infertility due to tubes is caused by previous genital tract infections, genital tuberculosis, intra-abdominal surgeries, endometriosis (chocolate cyst), hydrosalpenx (fluid accumulation in the tube, swelling due to obstruction) which cause obstruction and adhesion in the tubes.
The rate of tube-related infertility is between 25-35% in women.
Causes of infertility related to the ENDOMETRIUM (in the uterus)
Space-occupying lesions such as infections, adhesions (adhesions), polyps, fibroids in the cavity (intra-uterine) or endometrium (uterine lining layer) may prevent implantation (adhesion-settlement of the baby) and cause infertility.
CERVICAL FACTOR (causes of infertility related to the cervix)
Anti-sperm antibodies secreted from the cervix can rarely cause infertility by immobilizing the sperm. With vaccination and IVF treatments, antisperm antibodies have lost their importance.
Importance of female age and environmental factors in infertility
As women age, ovarian functions (ovarian reserve) decrease, and this decrease, which shows its effect after the age of 35, accelerates after the age of 40 and the chance of getting pregnant decreases to 10%. Deterioration in egg quality with age decreases the chance of conception and increases the risk of miscarriage in future pregnancies.
Factors such as cyst – tumor operations, endometrioma (chocolate cyst), radiotherapy, chemotherapy, smoking, which cause tissue and function loss in the ovaries (ovary), may cause ovarian-dependent female infertility by causing a decrease in the number of eggs.
