Infections

Certain infections have been known to affect a man’s fertility. In most instances the impact is temporary, but in the case of sexually transmitted infections (STIs), the effects can be severe.

Mumps

If a man has had mumps as an adult or a child, it should be mentioned to the healthcare provider or specialist. A common case of childhood mumps, in which the virus affects the glands below the jaw, does not normally lead to infertility. In 10%-30% of cases contracted in puberty however, it can affect the testicles, causing a condition called mumps orchitis. Some of these cases may experience reduced testicular function, which can lead to abnormal sperm count or motility.

Sexually Transmitted Infections (STIs)

Chlamydia can do permanent damage if not treated and can eventually lead to infertility. If a man had chlamydia several years ago and was treated for it, the residual effects can be destructive. If a man has been treated for STIs in the past (especially chlamydia), one of the following infertility diagnoses may apply:

  • Scarring in the urethra, which may impair or block the movement of sperm out of the body.
  • Epididymitis
Urinary Tract Infections (UTIs)

Recurrent UTIs are not necessarily a sign of a fertility problem, but are sometimes indicative of other problems. If a man has them regularly, it should be mentioned to the healthcare provider since it may suggest an immunological problem.
