What is the role of the prostate glands?
They add semen to the sperm to provide them with the energy they need to get through the female reproductive system
25 of 33
What is the role of the urethra?
It carries the sperm out of the penis
26 of 33

It protects the testis and also keeps them below body temperature in order to produce sperm
27 of 33
What is the role of the testis?
They produce sperm
