The main sign of low sperm count is the inability to conceive a child. There may be no other obvious signs or symptoms. In some cases, an underlying problem such as an inherited hormonal imbalance, dilated testicular veins or a condition that blocks the passage of sperm may cause signs and symptoms. Low sperm count symptoms may include:

  • Problems with sexual function — for example, low sex drive or difficulty maintaining an erection (erectile dysfunction)
  • Pain, swelling or a lump in the testicle area
  • Decreased facial or body hair or other signs of a chromosome or hormone abnormality

When to see a doctor

See a doctor if you:

  • Are unable to conceive a child after a year of regular, unprotected sexual intercourse with your partner
  • Have erection or ejaculation problems, low sex drive or other problems with sexual function
  • Have pain, discomfort, a lump or swelling in the testicular area
  • Have a history of testicle, prostate or sexual problems
  • Have had groin, testicle, penis or scrotum surgery
