How to treat
If these cycles are related to an outside influence like nutrition or lifestyle, effective treatments will include regulating eating habits and moderating physical activities. Making changes to your weight (gaining or losing weight ) may also be enough to restart ovulation.
There are drugs designed to ripen the follicles, increase estrogen, and help the ovaries release an egg.
