Yes sgc42,
Stress increases cortisol. The anterior pituitary gland adds up all sex steroid levels, including cortisol. If the total is too high, the gland decreases Luteinizing Hormone (LH). The decrease in LH slows the production of pregnenolone from cholesterol, and since all sex steroids are made from pregnenolone, their levels will decrease, including the progesterone level.
This negative feedback loop is one of the NBE essentials. Once you understand it, a lot on the forum will be easier to follow.
