Endocrine System

Your Endocrine System is responsible for the fast growth you experience during your teen years. The endocrine system is made up of glands located throughout the body. The pancreas is part of the Endocrine System because it secrets insulin. The chemicals secreted by the Endocrine Systems glands are called hormones.

Male Reproductive System

During puberty, the testes produce testosterone and sperm. Sperm mix with secretions from the seminal vesicles, the prostrate gland, and the Cowper's gland. Semen is created. Testes are the two small glands that produce sperm and hormones.

Female Reproductive System

New life is formed through the process of fertilization. Once fertilized the egg travels from the Fallopian tube to the uterus where it attaches to the wall of the uterus and begins to grow. Ovaries contain the ova, or eggs and produce hormones.


Common STD'S are Chlamydia, Genital Herpes, Genital Warts, Trichinosis, Gonorrhea, Syphilis, and Pelvic Inflammatory Diseases. Most STD'S are spread only through sexual contact. You cannot tell if someone has am STD by his or her appearance.

During puberty, egg cells mature and are released by the ovaries in a process called ovulation. If an egg is not fertilized, the uterus lining breaks down and is shed by the body through mensturation. Menstruation usually lasts from 5 to 7 days and happens about every 28 days.
