How are the Uterine Cycle and Ovarian Cycle controlled?
Cyclical changes, two cycles must be in synch for proper reproductive function
Involves changes in Ovarian follicles
Ovarian Cycle
Specialized structures around developing oocytes
Ovarian Follicles
Stimulates development of several follicles
Follicle Stimulating Hormone (FSH)
Egg follicle on an ovary gets ready to release an egg and a new endometrium layer starts growing
Follicular Phase
When are women most fertile?
The last 5 days of the follicular phase
Starts on ovulation day when the egg is released

Produced in the hypothalamus
Stimulates the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the pituitary gland
Gonadotropin-Releasing Hormone (GnRH)
Origin of Follicle-Stimulating Hormone (FSH)
Secreted by the pituitary gland
Stimulates the growth and development of ovarian follicles in the ovaries
Follicle-Stimulating Hormone (FSH)
Origin of Luteinizing Hormone (LH)
Released by the pituitary gland
Triggers ovulation and supports the development of the corpus luteum
Luteinizing Hormone (LH)
Origin of Estrogen
Produced primarily by the ovaries
Plays a crucial role in the development of female reproductive tissues and secondary sexual characteristics. It helps regulate the menstrual cycle
Estrogen
Origin of Progesterone
