ovarian cycle
- follicular - day 1-14 where immature follicles mature as a result of FSH. oocyte grows in follicle, ovum discharged into fimbria of fallopian tube
- luteal phase - days 15-28 where ovum leaves the follicle, ovum remains in the ampulla if fertilized, reaches uterus 72-96 hrs after release then implants into the endometrium and secretes human chorionic gonadotropin (hCG) OR if no fertilization, corpus leteum degenerates
28
What days of the ovarian cycle are females the most fertile?
13-15
29
Menstrual Cycle
- menstrual - shedding some endometrial cells
- proliferative - endometrial cells enlarge and thicken due to increased estrogen, peaking just before ovulation, cervical mucous is more elastic/thin/clear
