GnRH

- secreted from hypothalamus

- Function: Stimulates anterior pituitary for gonadotropins (FSH, LH) secretion

Gonadotropins

FSH and LH

- Secreted from pituitary

Function:

- LH- stimulate corpus lute and ovary in female

- FSH- follicular development in female

Estrogens

Secreted from:

- Estradiol (E2)

- Estriol (E3)

Function:

- E2:

- Development of secondary sex characteristics

- Maintains corpus luteum

, - Induce mitosis of endometrial (thickening endometrial)

- E3: maintain pregnancy

Progesterone

Secreted from ovary (corpus luteum) and placenta

Function:

- Stimulate differentiation of endometrium

- Implantation of fertilized ovum

- Maintain corpus lute and early stage of pregnancy

Prolactin-releasing hormone

Secreted from hypothalamus

Prolactin

Secreted from anterior pituitary

Function:

- Mammary gland development

- production at ovary

Hormone flow

Hypothalamus-(GnRH)- pituitary-(LH, FSH)- Ovary-(progesterone, E2)- target

Menstrual cycle

- at end of last cycle, last corpus lute is degrading- progesterone decreases and E2

decreases= menses

- LH reached to peak- ovulation after half day

- E2 and progesterone are secreted from corpus luteum

- progesterone inhibit LH and FSH secretion
