Name the different types of semen problems

Explanation

Abnormal semen is responsible for male infertility in more than 75% cases. The following semen problems are possible
Low sperm count (oligospermia) Sperm count should be 20 million sperms/mL of semen. If the count is under 10 million, there is a low sperm concentration.
No sperm When the man ejaculates, there is no sperm in the semen.
Low sperm motility The sperm cannot swim as effectively as it should.
Abnormal sperm Sometimes the sperms have unusual structures, making these more difficult to swim towards the egg and fertilise it.
