Leuteinizing Hormone (LH)
From : Anterior Pituitary |
Functions
* Males - stimulate interstitial cells to produce testosterone. * Females - Triggers ovulation and then promotes formation of the corpus luteum. |
|
|
Follicle-Stimulating Hormone (FSH)
From : Anterior Pituitary |
Functions
* Males - stimulate interstitial cells to produce sperm. * Females - initiates follicular growth. |
|
|
Testosterone
From : Leydig Cells |
Functions
* prenetal development of male sexual characteristics. * stimulation of anabolism for protein synthesis, causing heavier muscle and bone mass in male. * Development of male secondary sexual characteristics. * male and female sex drives. * it causes negative feedback to suppress release of LH and GnRH. |
|
|
Inhibin
From : Sertoli Cells |
Functions
* Causes negative feedback to suppress release of FSH, LH, and GnRH. |
|
|
Gonadotropin-Releasing Hormone (GnRH)
From Hypothalamus |
Functions
* Stimulates the secretion of LH and FSH. |
|
|
Estrogen
From : Developing follicles and corpus luteum and placenta. |
Functions
* promotes development and maintenance of female reproductive structures. * female secondary sex characteristics and breasts. * increase protein anabolism. * High levels inhibit release of GnRH, FSH, and LH. |
|
|
Progesterone
From : Corpus luteum and placenta |
Functions
* works with estrogens to prepard endometrium for implantation. * prepares mammary glands to secrete milk. * inhibits release of GmRH and LH. |
|
|
Relaxin
From : Corpus luteum and placenta |
Functions
* Inhibits contractions of uterine smooth muscle. * During labor, increases flexibility of pubic symphysis and dilates uterine cervix. |
|
|
Human Chorionic Gonodotropin (hCG)
From : by the chorion of the embryo |
Functions
* maintains corpus luteum for 3-4 months. |
|
|
Oxytocin
From : posterior pituitary |
Functions
* stimulates contractions. * milk ejection. * helps uterus to return to normal size after birth. * helps with the expulsion of the placenta. |
|
|
