Male infertility refers to the wife\’s inability to conceive due to the husband\’s illness when the couple has lived together for more than one year after marriage and did not use contraceptive measures. In the past, it was divided into two types: male infertility and male infertility. Male infertility means that the husband can get his wife pregnant, but the fetus cannot survive, such as miscarriage, stillbirth, etc.; while male infertility means that the husband cannot get his wife pregnant. Currently, the above two conditions are no longer distinguished and are collectively referred to as male infertility. The World Health Organization defines infertility as having sex without contraception for at least 12 months without conceiving. At present, the definition generally accepted in my country is: having a history of non-contraceptive sex for at least 2 years and failing to conceive the wife.
Male infertility involves many causes. For infertile patients, any disorder that causes sperm production, transportation, and the combination of sperm and eggs can lead to infertility. Common causes are testicular hypoplasia, cryptorchidism, orchitis complicated by mumps in pre-puberty, varicocele, lack of vitamin A and vitamin E, long-term exposure to high temperature and radiation, self-production of sperm antibodies, and congenital vas deferens. Sexual defects or post-traumatic stenosis, epididymis, vas deferens, seminal vesicles, prostate diseases, erectile dysfunction, no ejaculation, retrograde ejaculation, etc. The main clinical manifestation is infertility. Semen examination shows a decrease in sperm, below 60 million per milliliter, or sperm necrosis, deformity, and poor motility.
The main causes of male infertility are as follows:
(1) Sexual intercourse dysfunction: Erectile dysfunction, spermatorrhea, premature ejaculation, impotence and inability to ejaculate, etc., can all cause semen to be unable to enter the vagina.
(2) Sperm abnormalities:No sperm, low sperm volume, and poor sperm quality.
(3) Semen abnormalities: Hematospermia, white turbidity, semen failure to liquefy, etc.
(4) Semen output disorders:Congenital malformation of the external genitalia or teratogenesis caused by trauma, as well as inflammation of the organs along the reproductive tract, can block the vas deferens, preventing the normal output of semen. Or the internal bladder sphincter is not closed tightly or cannot be closed due to various reasons. Retrograde ejaculation occurs during sexual intercourse, and the semen cannot be ejected normally, resulting in the inability of sperm and egg to mate.
