The male

This system consists of two testicles, which hang between the hind legs, the penis, and two ducts which connect the testicles with the penis.

Reproductive organs of the bull

Stamens give the pollen that fertilizes the ovule in a flower (see Booklet No. 3, page 14).
Testicles give the semen that fertilizes the ovum.
The fertilized ovum becomes a young one in its mother's womb.
