Conditions InDepth: Infertility in Men

by Cynthia M. Johnson, MA

En Español (Spanish Version)

Infertility is not being able to conceive after a year of regular, unprotected sex. It may be due to male or female factors or both. Sometimes, the cause is in both partners or may not be known.

Male infertility is caused by problems making enough healthy sperm that are able to travel to an egg. Some causes may be:

Enlarged veins in the scrotum— varicocele
A blockage in the genital tract
Abnormal hormone levels
Infections, such as sexually transmitted infections (STIs), prostatitis, and tuberculosis
Undescended testicle(s)
Genetic problems such as Klinefelter syndrome
Sperm DNA damage
Problems with the immune system
Exposure to workplace chemicals or heavy metals, such as lead and cadmium
