=Reproductive System=
 * **Male Reproductive Hormones**: Testosterone made in the testes which are in the scrotum. Testes cells have testosterone receptors.The male starts making testosterone during puberty. Male keeps making testosterone until he dies. The signal is to make sperm. That signal is a daily signal!
 * **Female Reproductive Hormones**: Estrogen made in the ovaries. Ovary has estrogen receptors. The signal is to mature an egg. Estrogen is not released until puberty and stops at menopause. About every 2 weeks out of every menstrual cycle, Estrogen is released by the ovary. Progesterone is made in the ovary by the empty egg sac. Progesterone is made form puberty until menopause. Progesterone is released the last two weeks of the menstrual cycle. Progesterone receptors are found in the womb (uterus) and keeps the lining of the uterus thick.
 * **Male reproductive Organs**: Sperm pathway: Testes (sperm are made)--> Epididymis (sperm training pool)--> Vas Deferens--> Urethra
 * **Female Reproductive Organs**: Sperm Pathway: Vagina--> Cervix--> Uterus--> Fallopian Tubes (oviducts)

=Menstrual Cycle= Hormones used in the cycle:
 * The cycle lasts about 28
 * Its affected by travel, sports, physical activities, stress, eating habits
 * Day 1--> First day of period (sheds bloody lining), last for about 3-7 days
 * Days 8-11--> Bloody lining builds up in uterus in case you get pregnant again
 * Day 14--> **Ovulation**: egg is released so you can get pregnant to have a baby.
 * Day 18- 28--> Body waits to see if you fertilized to get pregnant
 * 1) **FSH:** made in the brain: pituitary gland
 * 2) the level is constant until ovulation
 * 3) receptors in the ovaries- time to mature egg
 * 4) **Estrogen**: made in the ovaries (alternating ovaries)
 * 5) the level increases the entire first part of the cycles and then drops and goes back up after ovulation
 * 6) when egg is produced, more estrogen is produced
 * 7) estrogen tells brain to release LH
 * 8) **LH**: made in the brain: pituitary gland
 * 9) level stays constant until right before ovulation. __It peaks after FSH__
 * 10) LH travels to ovary to tell it to release the egg
 * 11) **Ovulation**: release egg from ovary
 * 12) **Progesterone**: made in the ovary
 * 13) whats left in the ovary is an empty egg sac--> which produces progesterone.
