How many sperm are produced in the testes each day? 6,000 60,000 60 million 600,000?

The correct answer is 60 million.

A fertile male may produce between 40 million and 1800 million sperm cells in total, but the majority produce about 60 million sperm cells per millilitre. They need to be produced in very large amounts because not all of these cells have a normal shape and movement.
