FYI - Progesterone effects on body
“It raises epidermal growth factor-1 levels, a factor often used to induce proliferation, and used to sustain cultures, of stem cells.
It increases core temperature (thermogenic function) during ovulation.[37]
It reduces spasm and relaxes smooth muscle. Bronchi are widened and mucus regulated. (Progesterone receptors are widely present in submucosal tissue.)
It acts as an antiinflammatory agent and regulates the immune response.
It reduces gall-bladder activity.[38]
It normalizes blood clotting and vascular tone, zinc and copper levels, cell oxygen levels, and use of fat stores for energy.
It may affect gum health, increasing risk of gingivitis (gum inflammation) and tooth decay.[citation needed]
It appears to prevent endometrial cancer (involving the uterine lining) by regulating the effects of estrogen.
Progesterone plays an important role in the signaling of insulin release and pancreatic function, and may affect the susceptibility to diabetes or gestational diabetes”
