Reproductive+System+Notes-Faith

//Male Reproductive Hormones//
 * __Reproductive System__**
 * testosterone made in the testes which are in the scrotum
 * Testes cells have testosterone receptors
 * the male starts making testosterone during puberty
 * keeps making testosterone until death
 * The signal is to make sperm
 * that signal is a daily signal

//Female Reproductive Hormones// //Male Reproductive Organs//
 * Estrogen
 * made in the ovaries which have receptors
 * The signal is to mature an egg
 * not released until puberty and stops making estrogen during menopause
 * 2 weeks out of every menstrual cycle estrogen is released by the ovary
 * Progesterone
 * made in the ovary by the empty egg sac
 * is made from puberty until menopause
 * is released the last 2 weeks of the menstrual cycle
 * the receptors are found in the womb (uterus) and keeps the lining of the uterus thick
 * Sperm Pathway: Testes(sperm is made)-->epididymis(sperm training pool)--->vas deferens--> urethra-->

//Female reproductive organs//
 * Sperm Pathway: Vagina--> Cervix--> Uterus--> fallopian tubes (oviducts)

//Menstrual Cycle//
 * the cycle in general is about 28 days and varies a lot
 * days 1-7
 * menstruation beings
 * last 3-7 days
 * lining of uterus is being shed
 * days 8-11
 * the uterus gets thick again (rebuilds itself)
 * in preperation in case pregancy occurs
 * day 14
 * ovulation happens and when the egg is being released from the ovary
 * egg is available to be fertilized
 * body sees its not pregnant and the cycle repeats itself after waiting for 14 days (days 15-28)

//Menstrual cycle Hormones//
 * FSH
 * made in the brain (pituitary gland)
 * level is constant until right before ovulation it peaks then goes back down
 * receptors are in the ovary and tells the egg it is time to mature
 * Estrogen
 * made in the ovaries(alternates each cycle from one ovary to the next)
 * increases the entire first part of cycle then starts to drop before ovulation then starts to increase again after ovulation
 * comes from the maturing egg
 * LH
 * made in the brain (pituitary gland)
 * level is constant before ovulation and peaks right before FSH does then goes back down
 * the estrogen tells the brain to release this hormone
 * Ovulation
 * releasing of the egg from the ovary
 * LH goes to the ovary and tells to begins ovulation
 * Progesterone
 * made in the ovary
 * constant and starts to rise during ovulation and rises a lot after ovulation
 * is made by the empty egg sac in the ovary
