HCG is also used in men, or young boys who are going through puberty, to help increase the production of the male hormone testosterone in their bodies and to help produce sperm . In some cases, it can also be a solution to male fertility problems.

A special situation for boys:

Also, there are cases where this HCG injection is given to boys who have a special birth problem called cryptorchidism , in which the testicles do not descend properly at birth. This injection helps the testicles to return to their proper place.
