What Are the Causes of Infertility?

There are numerous reasons for female infertility, including physiological factors and diseases. Infertility is generally defined as the failure to conceive after one year of regular sexual activity without contraception. If the problem lies with the female partner, timely and formal hospital examination is recommended. Let's briefly explore the reasons that may lead to infertility.

1. Ovarian Dysfunction: This is characterized by the absence of ovulation during the menstrual cycle or the presence of ovulation with inadequate luteal function. Incomplete luteal secretion can lead to insufficient progesterone production, poor endometrial secretory response, and poor decidual response during early pregnancy. Even if pregnancy occurs, it may result in miscarriage due to inadequate luteal function.

2. Incomplete Genital Development: Infertility can also be caused by congenital or acquired genital organ abnormalities, which can obstruct the reproductive channels and interfere with the function of the reproductive organs, preventing the meeting of sperm and eggs.

3. Fallopian Tube Factors: Inflammation of the fallopian tubes can lead to tubal blockage, preventing the meeting of eggs and sperm. Pelvic endometriosis is also a cause of infertility.

4. Immunological Factors: The presence of anti-sperm antibodies in the female reproductive tract or serum can trigger an immune response against sperm, causing sperm aggregation, loss of vitality, or death, leading to infertility.

5. Sexual Dysfunction: Lack of sexual knowledge or the presence of other diseases or unknown causes in the female partner can contribute to infertility, accounting for approximately one-third of infertility cases.
