Function during the estrous cycle is unknown. Suppresses release of FSH from the pituitary. May be involved in the selection of the follicle destined to ovulate. Prostaglandin of the F series are involved in regression of the corpus luteum in the absence of a viable embryo in the uterus. Prostaglandin of the E series appear to be involved with maintenance of the corpus luteum, and may be involved in the process of ovulation.
Hormones are messengers.
They are produced and secreted by one part of the body and travel, usually through the bloodstream, to another part of the body to stimulate or depress a particular function. Hormones are the means by which distant parts of the body communicate with each other. Communication disturbances disrupt reproductive function. The target tissue, whether h is the ovary, uterus, pituitary or hypothalamus, responds only to specific pattern of hormone secretion that it recognizes.
