Endocrine system

Your Endocrine system is responsible for the fast growth you experience during your teen years. The chemicals secreted by the endocrine glands are called hormones. Each hormone has a specific job.


During puberty, the testes produce testorone and sperm. Sperm is the male sex cell. Some of the main problems in the male reproductive system is Testicular Cancer, STDs, or injury to the testes.

Female Reproductive system

The three functions of the female reproductive system is to store egg cells, create offspring and finally, give birth. New life is formed through the process of fertilization. Fertilization is when a male sperm cell joins with a female egg. During puberty, egg cells mature and are released b y the ovaries in a process called ovulation. Ovulation is the release of one mature egg cell each month. If an egg is not fertilized, the uterus lining breaks down and is shed by the body through menstration. Menstation is when the lining material, the unfertilized egg, and some blood flow out of the body.

Pregnancy and Labor

Fertilization is the union of a single sperm and ovum. This fertilized egg eventually becomes a baby. The Amonitic Sac is very important to the baby. It is a fliud filled sac that surrounds the embryo which protects it. The umbilical cord is also a big proportion to the baby because that is how it is fed. Prenatal care is care occuring or exsiting before the birth day. A normal or full term pregnancy lasts 9 full months or 40 weeks. Dangers to the fetus involve Alcohol, Tobacco, Medication/ Drugs, Caffeine, Rubella and Radiation. Labor is the process by which contractions gradually push the baby out of the uterus and into the vagina to be born.

Three stages of labor:

First stage of labor - contractions gradually open the cervix diameter of about 4 inches. This process is called dilation. Rupture of the Amniotic sac happens which is also known as Water Breaking. The first stage can last for 12 hours or longer. Second stage of Labor - Cervix is fully dilated and the mother pushes the baby's head throught the cervix and into the vagina. The mother continues to push until the baby is delivered. This stage generally lasts from 1/2 hour to 2 hours. Third stage of labor - final stage of labor lasts about 20 minutes. Contractions separate the placenta or afterbirth from the uterine wall and expel the placenta from the uterus and out of the body through the vagina.


STDs are sexually transmitted diseases that spread through sexual contact. Each year, one quarter of all new cases of STDs appear among 15 - 19 year olds. STDs can be bacterial or virus. The most common type of STDs are Chlamydia, Genital Herpes, Genital Warts, Trichomoniasis, Gonorrhea, Syphilis and Pelvic Inflammatory Disease. The best way to avoid an STD is to abstain from sexual contact.


An HIV is Human Immunodeficiency Virus whixh attacks T cells and replaces the genetic information of the T cells with its own genetic information. AIDS are acquired immunodeficiency syndrome. A person can be a carrier of HIV for ten years or more before starting to show symptoms of AIDS. This is why it is important to see a doctor after having sexual activity or even if you have few symptoms. HIV IS spread from person to person through contact with Sperm, fluid from the vagina, blood, and breast milk. It is NOT spread by breathing air, being bitten by a mosquito, swimming in a pool and sharing utensils.
