what stimulates the production of Androgen binding protein, a critical receptor of testosterone?
FSH
who produced interstitial cells are stimulated to produce testosterone after being stimulated by ________.
LH (also known as ICSH)
production site of OVA
Ovary
True or False: sex determination doesn't end with fertilization.
T
True or False: the sex of a child is determined at conception, and not by the mother's egg but by the sperm that fertilizes it.
T
luteal phase
The third phase of the ovarian cycle, during which a corpus luteum is formed from the remnants of the follicle that has ovulated its oocyte. The corpus luteum secretes progestrone and estrogen during this time period, which typically lasts from day 15 to day 28 of the menstrual cycle. Formation of the corpul luteum is triggered by the same LH surge that triggers ovulation, however in the absence of LH (levels quickly decline after the surge) the corpus luteum begins to degenerate.
