A normal sperm count ranges from 15 million sperm to more than million sperm per milliliter (mL) of semen. Anything less than 15 million.
Some men with low sperm counts successfully father children. Likewise, some men with normal sperm counts are unable to father children.
A complete absence of sperm is called azoospermia. Your sperm count is considered lower than normal if you have fewer than 15 million.
