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