- Menstrual cycle
- First phase is the follicular phase, FSH promotes the development of a follicle
- the follicle secretes oestrogen
- oestrogen spike leads to a surge in LH
- LH stimulates GC
- The antrum size increases
- follicular blood flow increases
- oestrogen release from GC decreases
- pregesterone release from GC increases
- Then there is enzymatic degregationof follicular ovarian membranes
- oocyte is released on day 14
- then moves into the luteal phase
- The LH promotes the development of the corpus lutem, the ruptured follicle becomes the corpus lutem
- CL releases progesterone and oestrogen, if no pregnancy the menstruation continues
- There is FSh and LH release again
- endometrium degenerates
- Then enters the proliferative phase
- endometrium and myometrium thicken, the progesterone receptors increase
