Symptoms

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, dilated veins around the testicle or a condition that blocks the passage of sperm causes signs and symptoms. Signs and symptoms you may notice include:

• Problems with sexual function — for example, difficulty with ejaculation or small volumes of fluid ejaculated, reduced sexual desire, or difficulty maintaining an erection (erectile dysfunction)
• Pain, swelling or a lump in the testicle area
• Recurrent respiratory infections
• Inability to smell
• Abnormal breast growth (gynecomastia)
• Decreased facial or body hair or other signs of a chromosomal or hormonal abnormality
• 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)

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
• A partner over age 35
