lactogensis occurs by fall in ^^ levels
what happens during the menstrual cycle when FSH and LH fall? [1]
FSH and LH fall, the corpus luteum degenerates
Degeneration of the corpus luteum results in loss of progesterone production.
The subsequent falling level of progesterone triggers menstruation and the entire cycle begins again

combination of which two molecules induces spermatogenesis? [2]
testosterone and androgen binding protein
- Gonadotropin releasing hormone (GnRH) stimulates FSH & LH from AP
- LH stimulates testosterone production by Leydig cells*
- •Main target of testosterone and pituitary FSH are Sertoli cells*
- •Sertoli cells then secrete androgen binding protein (ABP) and tubular fluid*
- •ABP binds to testosterone & carries it to area of seminiferous tubule where it stimulates spermatogenesis*
which cells form the blood-testis barrier?
sertoli cells
