Reproductive Organs

The reproductive system consists of three main parts: the ovaries, testes and uterus. These are all located inside the body, but they differ in size and function depending on whether it’s a man or woman.

Ovary (ov) – The ovary is where eggs are produced from which will eventually become children. Eggs come from the ovaries when women get pregnant with their own eggs or those of other women during menstruation. A fertilized egg develops into a baby through the mother’s body.

If a woman doesn’t have any eggs left after her period ends, she’ll go on birth control pills to prevent pregnancy until she does have enough eggs.

Testis (test) – The testicles produce testosterone which helps men grow stronger muscles and make them better fighters. Testosterone makes men more aggressive and competitive than women. Some studies show that high levels of testosterone may cause cancer.

Low levels of testosterone can lead to low energy, depression and loss of libido.

Uterus (t) – The uterus is where a baby will develop if the right conditions are met. A woman needs to be fertile before she can get pregnant naturally or with a partner who isn’t already married. Women can get pregnant naturally when they’re not using contraception such as condoms or withdrawal methods like the pill.

All 3 parts of the reproductive system need to be in working order for a man or woman to reproduce. During puberty, hormones will cause these organs to grow larger and produce the right amounts of hormones. Most people’s bodies will develop eggs, testicles and a uterus fully by age 13, but this process can take longer depending on the person.

After puberty is over, these reproductive organs don’t need any more attention unless a boy or girl wants to have children. Most people will start going through puberty between the ages of 10 and 16, but some people will be earlier or later than that. Puberty begins with a growth spurt that lasts for about 2 years, and is followed by the development of reproductive organs and pubic hair.

After puberty, a girl’s period will usually start at some point between age 10 and 16. During puberty, boys will grow taller and start producing more testosterone. Pubic hair should also grow as well.
