The main sign of male infertility is the inability to conceive a child. There may be no other obvious signs or symptoms. In some cases, however, an underlying problem such as an inherited disorder, hormonal imbalance or a condition that blocks the passage of sperm may cause signs and symptoms. Male infertility signs and symptoms may include:

  • The inability to conceive a child
  • Problems with sexual function — for example, difficulty with ejaculation 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 chromosomal or hormonal abnormality
  • Having a lower than normal sperm count (fewer than 15 million sperm per milliliter of semen or a total sperm count of less than 39 million per ejaculate) or other abnormalities in semen parameters .
