Some couples can have sex and ejaculate, and the woman’s examination shows no abnormalities, but they cannot have children. Why is this? Generally speaking, if there is ejaculation, most people are fertile, but a few people have ejaculation but are not fertile. The reasons are:
(1) Oligospermia or azoospermia caused by various reasons: Due to no sperm production or reduced sperm production, although there is ejaculation, there is no sperm in the semen. No sperm or too few sperm can also cause infertility.
(2) Obstruction of the vas deferens: Although the testicles produce sperm, due to obstruction of the sperm output duct, the sperm cannot be discharged from the body, which can lead to infertility.
(3) Abnormal sperm outflow channel: The testicles can produce sperm and can also ejaculate, but the semen is not ejected into the female vagina, but outside the vaginal opening, such as congenital Abnormal hypospadias, epispadias, etc. Another cause is retrograde ejaculation. There is a feeling of ejaculation during ejaculation, but the semen flows backward from the posterior urethra into the bladder, causing infertility. The main reason is abnormality of the bladder neck or abnormal function of the nerves that control the lower urinary tract.
