<P> The development of the corpus luteum is accompanied by an increase in the level of the steroidogenic enzyme P450scc that converts cholesterol to pregnenolone in the mitochondria . Pregnenolone is then converted to progesterone that is secreted out of the cell and into the blood stream . During the bovine estrous cycle , plasma levels of progesterone increase in parallel to the levels of P450scc and its electron donor adrenodoxin , indicating that progesterone secretion is a result of enhanced expression of P450scc in the corpus luteum . </P>
