Symptoms

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 men, 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

When to see a doctor

See a doctor if you have been unable to conceive a child after a year of regular, unprotected intercourse or sooner if you have any of the following:

• Erection or ejaculation problems, low sex drive, or other problems with sexual function
• Pain, discomfort, a lump or swelling in the testicle area
• A history of testicle, prostate or sexual problems
• A groin, testicle, penis or scrotum surgery
