Oligospermia

If the result of a semen analysis shows that the concentration of sperm in the ejaculate is lower than the lower limit of the established standard (15 million sperm per millilitre of semen), then this is oligospermia. The most common causes of low sperm production include hormonal problems, blocked ducts, infections, side effects of certain medications, and lifestyle factors - e.g. excessive alcohol consumption, smoking or frequent bathing in hot water or saunas.
