Estrous Cycle Topic 3096 C Amanda Trutsch

Estrus The period of mating activity in the female mammal Same as heat

Estrous An adjective meaning “heat”, which modifies such words as cycle Estrous cycle is the heat cycle, or time from one heat to the next

Hormones involved Gonadotropin-releasing hormone (GnRH)  Source: Hypothalamus  Target: Anterior pituitary  Function: Release LH and FSH

Luteinizing hormone (LH)  Source: Anterior pituitary  Target: Ovary  Functions: Ovulation, CL formation, Progesterone production Hormones involved, cont.

Follicle-stimulating hormone (FSH)  Source: Anterior pituitary  Target: Ovary  Function: Development of follicle

Hormones involved, cont. Estrogen  Source: Follicle  Target: Uterus  Function: Mating behavior

Hormones involved, cont. Progesterone  Source: Corpus luteum  Target: Uterus  Function: Maintains pregnancy

Hormones involved, cont. Prostaglandin (PGF 2a )  Source: Uterus  Target: Corpus luteum  Function: Regression of CL
