GnRH Source

Hypothalamic surge and tonic centers

LH Source

Anterior lobe

FSH Source

Anterior lobe

Oxytocin Source

Synthesized in the hypothalamus, stored in the posterior lobe of the pituitary; synthesized by the corpus luteum

Estradiol Source

Granulosal cells of the follicle, placenta, Sertoli cells of testis

Progesterone Source

Corpus luteum and placenta

Testosterone source

Interstitial cells of leydig, cells of the theca interna in females

Inhibin source

Granulosal cells (female) and Sertoli cells (male)

PGF2a Source

Uterine endometrium, vesicular glands

GnRH Target Tissue

Male and Female: anterior lobe of the pituitary

GnRH primary action

Male and Female: Release of FSH and LH from anterior lobe of pituitary

LH target tissue

male: Testis (Sertoli cells), female: Ovary (granulosa cells)

LH primary action

male: sertoli cells function, female: Follicular development and estradiol synthesis

Oxytocin female target tissue

Myometrium and endometrium of uterus, myoepithelial cells of mammary gland

Oxytocin female primary function

Uterine motility, promotes uterine PGF2⍶ synthesis, milk ejection

Estradiol female target tissue

Uterine endometrium, mammary gland, myometrium, hypothalamus

Estradiol female primary function

Endometrial secretion, inhibits GnRH release, inhibits reproductive behavior, promotes maintenance of pregnancy

Testosterone male target tissue

male: Accessory sex glands, tunica dartos of scrotum, seminiferous epithelium, skeletal muscle

Testosterone male primary action

Anabolic growth, promotes spermatogenesis, promotes secrtion of accessory sex glands

Testosterone female primary action

Substrate for estradiol synthesis, abnormal masculinizataion

Inhibin target tissue

anterior lobe of pituitary

Inhibin primary function

inhibits FSH secretion

PGF2a female target tissue

Corpus luteum, uterine myometrium, ovulatory follicles

PGF2a female primary action

Luteolysis, promotes uterine tone and contraction, ovulation
