Reproductive System Hormonal Feedback Loop

What is the role of the hypothalamus in the female reproductive cycle?

During which phase does FSH stimulate ovarian follicles to mature?

Which hormone is primarily responsible for maintaining the uterine lining after ovulation?

What happens if fertilization does not occur after ovulation?

Which hormone is involved in the regression of the corpus luteum?

Reproductive System Regulation Diagram

Diagram presents a hormonal feedback loop regulating reproduction.
Hypothalamus releases GnRH (Gonadotropin-releasing hormone), stimulating the pituitary gland.
Pituitary gland releases FSH (Follicle-stimulating hormone) and LH (Luteinizing hormone).
FSH stimulates follicle growth in the ovaries, producing estrogen.
Estrogen, in turn, causes the hypothalamus to decrease GnRH release.
LH triggers ovulation and development of the corpus luteum.
Corpus luteum produces progesterone, maintaining the uterine lining.
Progesterone also inhibits GnRH release.
If no fertilization, corpus luteum breaks down, progesterone levels drop, and menstruation occurs.
If fertilization occurs, the developing embryo secretes hormones to maintain the corpus luteum.
Trophoblastine released by the developing embryo helps maintain the uterine lining.
This diagram represents the interconnected elements of the hormonal cascade controlling the reproductive cycle.
The diagram illustrates a negative feedback loop, with hormones regulating their own release.
There are positive feedback loops involved too.

This quiz explores the hormonal feedback loop regulating the reproductive system. It covers the roles of the hypothalamus, pituitary gland, and various hormones such as GnRH, FSH, LH, estrogen, and progesterone. Understand each hormone's function and the consequences of fertilization or lack thereof.
