Endocrine System

• Estrogen stimulates growth and development of secondary sex characteristics such as breast enlargement, pubic hair, and widening of hips.
• Progesterone prepares the uterus for pregnancy by thickening its walls and maintaining the uterine lining until the baby can survive outside the womb.
• The follicle stimulating hormone (FSH) signals the testes and ovary to produce sperm and egg cells. (Spermatogenesis and Oogenesis)
• The luteinizing hormone (LH) stimulates the production of testosterone in the male and estrogen and progesterone in the female.
• Pituitary gland is the master gland of the endocrine system. It controls the functions of other glands.
• Testosterone is responsible for regulating sex differentiation, and secondary male characters.
• Spermatogenesis is the development of sperm cells.
• The luteinizing hormone (LH) plays a role in the development of ova, stimulation of estradiol (estrogen) and progesterone production.
• Oogenesis is the development of egg cells.
• Estrogen is released prior to ovulation.

  Progesterone is released after ovulation.
• Homeostasis is a state of balance among all the body systems needed for the body to survive and function correctly.
