female hormonal cycles
ovarian cycle
day 1-14 follicular phase: FSH and LH cause several follicles to grow
day 15 ovulation: growing follicles increase amt of estrogen in body, making FSH + LH lvls to rise. the spike in LH makes the most mature follicle release its egg.
day 16-28 luteal phase: corpus luteum forms to support released egg. this supplies a lot of hormones. if pregnant: CL dies after 10 days / else: corpus luteum is placeholder for placenta
menstrual cycle
days 0-4 menstrual phase: uterus bleeds out everything but deepest parts of endometrium
days 5-14 proliferative phase: endometrium is rebuilt. ovulation occurs @ end of this phase
days 15-28 secretory phase: progesterone is produced by ovaries + corpus luteum
hormones
female

progesterone: maintains endometrium
male
testosterone: deepens voice, increases hair growth, bone and muscle mass
HGP AXIS
FSH: stimulates follicle growth
LH: triggers ovulation in females and release of testosterone in males
GNrH: indirectly stimulates testes/ovaries via FSH + LH release
disorders
