Semen collection

Semen is a liquid that comes out of a man's private parts during ejaculation. It's made up of tiny cells called sperm, which are important for making babies.

Sometimes, doctors or other people need to collect a man's semen for different reasons. This is called semen collection.

To do this, a man is asked to masturbate, which means one must use their hand to give themselves pleasure in their private parts until they ejaculate. Then, a special container is used to catch the semen when it comes out.

The semen is then sent to a laboratory, where it's checked to see how many sperm are in it and whether they look healthy. This can help doctors figure out if there are any problems with a man's fertility or if he has any sexually transmitted infections.

Sometimes, men may feel a bit embarrassed or nervous about masturbating to collect semen. But it's a really important thing to do if the doctor asks for it. The container is perfectly safe to use, and nobody else will be looking at the semen except the people who need to check it in the laboratory.
