Male infertility usually has no obvious precursors, and some men may have symptoms such as low semen, no semen, and erectile dysfunction. Generally couples who have had normal sex for more than a year without contraception, and the woman fails to conceive due to the man after the woman’s infertility has been ruled out, are referred to as male infertility. Male infertility usually has no obvious precursors and is usually difficult to detect in advance. There are many causes of male infertility, such as semen abnormalities, spermatogenic disorders, sperm-egg binding disorders or some systemic factors. Some patients may have symptoms such as oligospermia, azoospermia and erectile dysfunction. If the couple is not contraceptive but not pregnant for a long time, it is recommended to go to the hospital for examination in time, and then actively carry out the appropriate treatment.
