Stimulation is an important part of IVF treatment. Naturally, the ovaries typically release one egg during the woman’s menstrual cycle. Whereas an IVF treatment cycle makes provision for multiple eggs. your doctor will prescribe a course of drugs (tablets and injections) that would make you produce more than the usual one egg (you can have between 10 to 20 eggs). This affords the luxury of selection of matured eggs vis-à-vis good embryos. Upon maturation of the follicles, another hormonal injection is administered before egg retrieval in the IVF theatre.
