prolactin releasing factor and testosterone/estrogen depending if it is male or female

Estrogen and testosterone share a common hypothalamic releasing factor. Estrogen is made in a woman's ovaries, and testosterone in a man's testicles.

1. hypothalamus controls pituitary gland hormones by releasing its hormones namely growth hormone releasing factor ,somatostatins,cortical releasing factor,thyroid releasing factor,
2. prolactin releasing factor,prolactin release inhibiting factor.,gonadotrophin releasing factor, etc.
3. thus the released gonadotrophin acts on pituitary gland ,
4. .pituitary is endocrinally divided into 3 parts in which anterior one called as adenohypophysis,while posterior one called as neurohypophysis,and middle one of no endocrinal use.
5. adenohypophysis stimulate it to release follicle stimulating hormone and LH hormone.
6. the follicle stimulating hormone acts on testis and ovary and stimulates them to release testosterone and progesterone.
7. thus follicle stimulating hormone released by adenohypophysis.[anterior pituitary]
