Signs of decreased sperm count in men

Decreased sperm count means that the number of sperm is less than normal. Deficiency of sperm count reduces the likelihood of pregnancy. In some men, underlying problems such as hereditary chromosomal abnormalities, hormonal imbalances, dilation of the testicular veins, or a problem that blocks the movement of sperm may cause symptoms. Of course, the cause of sperm deficiency is often unknown.
