Dydrogesterone and Dienogest are very very helpful medications in treating endometriosis condition, and Dydrogesterone helps many women to become pregnant. They are widely used around the world and help a lot of women.
But in US Dydrogesterone was discontinued a long time ago. In US women have access to only a single type of progesterone - Norethindrone or Depo Provera, which is not good in helping with endometriosis or infertility. Dydrogesterone, Dienogest, Desogestrel - are not FDA approved. Why so? So many women suffer from endometriosis and Depo Provera (which is usually prescribed) has sooooo many side effects and fertility restored up to 2 years! Norethindrone or Depo Provera are the worst options for women, and they are the only option available in US. Why is it the case? Why Dydrogesterone was discontinued?
