Infertility in men

1. Sperm disorders

Naturally, sperm is produced in the testicle and goes out of the body during ejaculation. If there is a disorder in the following cases, the chance of fertilization is reduced.

  • ‌Low sperm count
  • ‌Sperm immaturity
  • Abnormal sperm shape
  • Inability in proper movement

Factors that affect the number, shape, maturity and motility of sperm are:

  • ‌ Infectious diseases: Infectious diseases with inflammatory conditions, such as mumps cause genital infections or inflammation and testicles disappear in the male. About 25% of men who have mumps after puberty become infertile.
  • Hormonal disorders.
  • Hormonal disorders cause about 2-5% of infertility problems in men. The inappropriate production of FSH and LH hormones affects the production of masculinity or testosterone hormones and the production of sperm.
  • Problems with the immune system.
  • In the body of some men, a substance is produced called antibody that reduces the movement of the sperm or binds them together.

2. Abnormalities related to body building

Some factors, such as closure of the sperm outflow tubes (epididymis), cause infertility in men. The closure of the sperm outflow tubes can be due to congenital, genetic defects, infections, or genitourinary inflammation. Of course, prior surgery can also close those tubes. Among other factors, infertility in men is varicocele. In this case, the veins in the testis are dilated and the quality of the sperm decreases.

3. Other factors

Other factors, such as sexual inability or early ejaculation can also be the cause of infertility in men.
