When your body reaches a certain age, your brain releases a special hormone that starts the changes of puberty. It's called gonadotropin-releasing hormone, or GnRH for short. When GnRH reaches the pituitary gland (a pea-shaped gland that sits just under the brain), this gland releases into the bloodstream two more puberty hormones: luteinizing hormone (LH for short) and follicle-stimulating hormone (FSH for short). Guys and girls have both of these hormones in their bodies. And depending on whether you're a guy or a girl, these hormones go to work on different parts of the body. For guys, these hormones travel through the blood and give the testes the signal to begin the production of testosterone and sperm. Testosterone is the hormone that causes most of the changes in a guy's body during puberty. Sperm cells must be produced for men to reproduce. In girls, FSH and LH target the ovaries, which contain eggs that have been there since birth. The hormones stimulate the ovaries to begin producing another hormone called estrogen. Estrogen, along with FSH and LH, causes a girl's body to mature and prepares her for pregnancy. So that's what's really happening during puberty - it's all these new chemicals moving around inside your body, turning you from a teen into an adult with adult levels of hormones.

Fertilisation normally occurs high up in the Fallopian tube.

This embedding is known as implantation. After implantation the developing embryo releases a chemical into the mother's blood preventing menstruation and so failure to menstruate is often the first sign of pregnancy.
