Female Sex Organs

Labia: Give and receive pleasure during sexual intercourse. Entrance to vagina.

Vagina: Give and receive pleasure during sexual intercourse. Receives sperm and transports it to the cervix.

Cervix: opening to the uterus/womb.

Uterus: The place in the female body where the egg matures to form a baby during pregnancy.

Ovaries: The female gonads - produce the female 'sex' cells containing half of the DNA used to create a new unique human being. ALSO produces estrogen - the hormone that causes women to develop different physical musculature, vocal quality and behaviour from men.

Fallopian tubes: bring the mature egg to the uterus. Fertilization of the egg (the joining of the sperm and the egg) takes place in the fallopian tubes if pregnancy is too occur.

Male Sex Organs: Diagrams and Descriptions

Penis: gives and receives pleasure during act of intercourse. Delivery system for sperm into the vagina.

Urethra: tube through penis. Urine passes through the urethra and out of the body as well as the male ejaculation during sexual intercourse.

Scrotum: sack of skin at base of penis. Keeps testicles at optimum temperature for sperm production- about 35 degrees Celsius. Normal body temperature (37 degrees) is too warm.

Testicles - the male gonads. Produce sperm - 'sex' cells containing half of your DNA information used to create a new unique human being. ALSO produces testosterone - the hormone that causes men to develop different physical musculature, vocal quality and behaviour from women.

Epididimus: Storage area for mature sperm cells - attached to testicles  

Vas Defer (also refered to as Vas Deferens) - delivers sperm to the urethra for passage through the penis. When a man has a vasectomy these tubes (one for each testicle) are cut and healthy active sperm are no longer part of the male ejaculation.

Prostate Gland - produces an alkaline fluid that keeps sperm healthy during the passage through the urethra and inside the vagina.

Cowper Gland: produces a fluid that helps neutralize the residual uric acid in the urethra.

Bladder: storage area for urine - unwanted bodily fluids removed from the blood stream by the kidneys - before being passed from the body.
