Where does LH bind and what does it effect in males?
Luteinizing hormone. Binds to interstitial endocrine cells and secretes testosterone. Increase in test levels trigger spermatogenesis. `
What does LH effect in females?
Rising levels of LH cause the ovary wall to rupture, expelling secondary oocytes
What does FH effect in males?
Follicle stimulating hormone stimulates spermatogenesis indirectly by stimulating systems to release androgen binding protein.
What does FH effect in females?
During the follicular phase, several vesicular follicles are stimulated to grow. Triggered by rising levels of FSH. Drops around middle of follicular phase
What does GnRH stand for, what releases it, and what does it secrete?
Gonadotropin releasing hormone. Released by anterior pituitary gland. Secretes FSH and LH.
