Endometrial hyperplasia is not cancer; it is caused by a prolonged absence of ovulation, which means there is no secretion of progesterone. This prevents the proliferative phase endometrium from transforming into the secretory phase, leading to hyperplasia. If the hyperplasia persists over an extended period, it may lead to precancerous changes in the endometrium, and in severe cases, it can cause endometrial cancer. Therefore, it is essential to treat endometrial hyperplasia with progesterone, which can transform the endometrium and allow it to shed completely, altering its condition and restoring it to normal. As long as there is ovulation, there is the production of progesterone, so promoting ovulation is crucial.
