- epididymides;
- sperm ducts;

A man’s internal sexual organs are: 1. testicles, 2. epididymides, 3. sperm ducts, 4. prostate, 5. seminal vesicles.
Testicles
A man has 2 testicles: one of the testicles may be smaller than the other one or hang a bit lower.
The testicles are in the scrotum.
They produce millions of sperm cells.
Epididymides
A man has 2 epididymides.
Each one is connected to one testicle.
The sperm cells are kept in the testicles. They can also grow further there.
Sperm ducts
A man has 2 sperm ducts.
Each one is connected to one epididymis.
They transport the sperm cells to the prostate.
Prostate
The prostate lies below the bladder. It is the size of a strawberry.
Fluid is added to the sperm cells in the prostate. Together the fluid and the sperm cells make up the semen. During ejaculation the prostate contracts and pushes out the semen. The entrance of the bladder also contracts at the same time. This prevents semen from entering the bladder and stops urine from leaking into the semen.
Seminal vesicles
A man has 2 seminal vesicles. They lie next to the prostate. They add more fluid to the sperm cells.
