If a couple lives together and has a normal sex life and does not get pregnant for more than a year, it is clinically known as primary infertility. There are many reasons for primary infertility in women, such as ovulatory dysfunction, which can cause infertility because although there is normal menstruation, there is not necessarily ovulation. In addition, if the fallopian tubes are blocked or congenitally atretic, there is no way for the sperm and egg to combine, making pregnancy impossible. If there is immune infertility, that is, if the woman has anti-sperm antibodies in her body or if she has anti-endometrial antibodies, a condition that has no clinical symptoms but can be detected by laboratory tests, it can also cause infertility. Therefore, for infertility, a detailed examination should be done to find out the cause of infertility, and if treatment is given for the cause of infertility, pregnancy can be achieved.
