|
Gonadotropin releasing hormone
|
hypothalamus:
stimulates release of FSH and LH targets anterior lobe pituitary |
|
|
Lutenizing Hormone
|
Anterior pituitary:
Male: targets Leydig cells in testes, stimulates testosterone production Female: targets ovaries (theca interna and luteal cells), stimulates OVULATION |
|
|
Follicle Stimulating Hormone
|
Anterior Pituitary:
Male: targets and stimulates Sertoli cells of testes Female: targets granulosum cells of ovary, stimulates follicular development and estradiol synthesis |
|
|
Oxytocin
|
Synthesized in HYPO and Corpus Luteum, stored in Posterior Pituitary
Male: targets smooth muscle of epididymus, ductus deferens and ampulla. Aids in sperm movement, stimulates PGF synthesis Female: targets uterus, promotes uterine motility, PGF(2a) synthesis, |
|
|
Prolactin
|
Anterior pituitary:
Males: can induce paternal behavior Females: induces lacation, maternal behavior, smooth muscle contractions, and stimulates PGF(2a) |
|
|
Estradiol
|
From follicular granulosa (females) or Sertoli cells (male)
Male: inhibits long bone growth(?) Female: sexual behavior, GnRH, stimulates internal tract secretions, uterine motility |
|
|
Progesterone
|
Corpus Luteum
Female: targets uterine endometrium and myometrium, hypothalamus. Stimulates endometrial secretions, inhibits GnRH release, promotes maintenance of pregnancy |
|
|
Prostaglandin F(2-alpha)
|
From uterine endometrium
Female: Luteolysis, promotes uterine tone and contraction, ovulation >>Vasoconstrictor |
|
|
Testosterone
|
Source - Male: Leydig Female: theca interna
Female: Substrate for E2 synthesis Male: anabolic growth, promotes spermatogenesis, secretion of accessory sex glands |
|
|
Activin
|
From granulosal cells (female), or Sertoli cells (male)
Targets gonadotrophs of Anterior Pituitary Stimulates FSH secretion |
|
|
Inhibin
|
From granulosal (female) or Sertoli (male) cells
Targets gonadotrophs of Anterior pituitary Inhibits FSH secretion |
