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)
