The best and fastest menstrual stimulants are progestogen drugs, such as progesterone capsules, progesterone injections, and medroxyprogesterone acetate tablets. Generally, menstruation will occur 3-5 days after stopping the medication for 3-5 days. However, the basis for progesterone to exert its menstrual-promoting effect is normal estrogen levels and good endometrial hyperplasia. If the body itself lacks estrogen, resulting in poor endometrial hyperplasia, or if the estrogen level is normal but the uterus suffers from serious diseases that cause poor endometrial hyperplasia, such as endometrial tuberculosis, uterine adhesions, etc., progesterone alone will not promote menstruation. The use of progesterone alone is also not effective in promoting menstruation and needs to be treated for the primary disease first. As for various kinds of food, no matter which kind of food, there is no exact menstruation-promoting effect, but only food has the therapeutic effect of supplementing vitamin-like nutrients and balancing the ovarian endocrine function. Women with menstrual disorders and irregular menstruation should eat more soy products as appropriate.
