Q

Describe the follicular phase of menstruation

A

FSH, follicles mature, graafian follicle produces estrogen which thickens endometrium and thins cervical mucus. Oestrogen initially suppresses LH until threshold then sudden spike of LH day 12. 24-48hrs after LH surge follicle ruptures and releases secondary oocyte which quickly matures into ootid then mature ovum which enters fallopian tube.

Q

Describe the luteal phase of menstruation

A

LH + FSH turn the ruptured follicle into the corpus luteum which produces progesterone – makes endometrium receptive, increases estrogen production, negatively feeds back on LH+FSH. When they fall the corpus luteum degenerates so drop in progesterone that causes menstruation.
