Oligospermia means low sperm count. When you ejaculate, the fluid or semen that you produce during an orgasm contains fewer than normal sperms it is called oligospermia.

Oligospermia is different from azoospermia, which is the complete absence of sperm. Your sperm count is considered low if you ejaculate less than 15 million sperm per millilitre of sperm. A healthy sperm count increases the odd for fertilization with your partner’s egg, resulting in a pregnancy. Nonetheless, men with a low sperm count may still be able to get pregnant with their partners.

Typically, a male may experience other sexual conditions with oligospermia, such as the inability to get or maintain an erection, as well as produce ejaculation at orgasm.

Having a low sperm count decreases the odds that one of your sperm will fertilize your partner's egg, resulting in pregnancy. Nonetheless, many men who have a low sperm count are still able to father a child.
