"Progesterone modulates the activity of CatSper (cation channels of sperm) voltage-gated Ca2+ channels. Since eggs release progesterone, sperm may use progesterone as a homing signal to swim toward eggs (chemotaxis). Hence substances that block the progesterone binding site on CatSper channels could potentially be used in male contraception.[34][35]
Progesterone is sometimes called the "hormone of pregnancy",[36] and it has many roles relating to the development of the fetus:
Progesterone converts the endometrium to its secretory stage to prepare the uterus for implantation. At the same time progesterone affects the vaginal epithelium and cervical mucus, making it thick and impenetrable to sperm. If pregnancy does not occur, progesterone levels will decrease, leading, in the human, to menstruation. Normal menstrual bleeding is progesterone-withdrawal bleeding. If ovulation does not occur and the corpus luteum does not develop, levels of progesterone may be low, leading to anovulatory dysfunctional uterine bleeding.
During implantation and gestation, progesterone appears to decrease the maternal immune response to allow for the acceptance of the pregnancy.
Progesterone decreases contractility of the uterine smooth muscle.[36]
In addition progesterone inhibits lactation during pregnancy. The fall in progesterone levels following delivery is one of the triggers for milk production.
A drop in progesterone levels is possibly one step that facilitates the onset of labor."
Would have tried explaining it in words but wikipedia does it so much better
lmao. Your progesterone drops when you get AF as well, which is why you see the massive temp dip. You have to have good progesterone in order to maintain a healthy pregnancy, which is why a lot of women have to take supplements after having multiple miscarriages.
As for clomid, not sure about that- I know it helps you O or helps you O stronger so maybe it makes the other hormones stronger as well?? I mean, Rachel had a whopping 43 one month and wasn't pregnant, meanwhile Julie had a 10 and was pregnant with twins, so it obviously differs greatly
Hope I helped and wasn't just spewing crap that you didn't care about hahahhaa.
