This liquid has in it male sex cells. These cells are called sperm cells. Sperm cells are made in the male sex glands - testes. The liquid with cells forms in another gland. This gland is below the bladder. This gland is called the prostate. The male urethra passes through the prostate and goes on through another organ. This male organ is a tube with the urethra. This tube is on the front of a man's body below the abdomen. This tube is called the penis.
