Endocrine System

You can care for your endocrine system by getting enough sleep, handling stress well, exercising daily, and eating healthy foods. Problems with the endocrine system include diabetes, overactive thyroid gland, and an under active thyroid gland. When you have stress, your heart rate increases and your blood level rises.

Male Reproductive System

Semen is produced in the testes. The scrotum protects the testes. Once blood rushes to the penis and you ejaculate sperm, a baby can be conceived. A problem with the male reproductive system is infertility.

Female Reproductive System

The egg is fertilized in the fallopian tube and then moves down to the uterus. The 9 month pregnancy consists of three trimesters. Each trimester lasts three months. At the end of the third trimester, the baby is born.


The menstrual cycle restarts every month. Menstruation happens because the extra lining of blood around the uterus is released when the egg is not fertilized. If your period is late, you may be pregnant because the blood isn't released if the egg is fertilized.

Pregnancy and Labor

The embryo becomes a fetus a few weeks into pregnancy. An ideal birth includes the baby exiting the vagina head first. When your water breaks, the protective shield around the baby has broken and needs to be delivered.


HIV is ONLY spread from blood, semen, vaginal discharge, and breast milk. HIV is commonly unnoticed because it doesn't show symptoms. A baby can get HIV from their mother before or after birth.


Many STDs have mild or no symptoms. Despite what many people think, a lot of STDs can be treated and cured if found early. Some STDs are painless although others are very painful.


Practice abstinence to avoid contracting STDs as it is the only 100% method. To stay abstinent avoid sharing needles and being alone on a date. Avoid use of alcohol as you might do something that you are unaware of.
