What causes infertility?

Causes of Infertility. Both men and women can have problems of infertility. Male (sperm) and female (egg/fallopian tubes/uterus) factors each account for one-third of infertility cases, and the remaining one-third are either due to joint problems or unexplained.

Male factors: Unfavourable life habits such as smoking and drinking, undescended testes, varicose vein in the scrotum, or damage of the genital organs from operation or inflammation can affect the production or transportation of sperms and cause infertility. Hereditary factors can also lead to azoospermia or very low sperm count.

Female factors: Infertility can result from ovarian insufficiency, abnormal ovulation due to hormonal disturbances, blockage of fallopian tubes or pelvic adhesion caused by pelvic inflammatory disease or endometriosis, as well as congenital structural abnormalities of the uterus. Besides, women's reproductive potential falls as they get older, especially after age 40.
