Welcome to the ehealthforum and I am really glad to help you out.

Gonadotrophins like FSH are usually started on day two or three of the menstrual cycle. he follicle size is monitored with ultrasound, and the blood estrogen level may be measured frequently throughout treatment. If estradiol levels and follicular monitoring indicates that the ovaries are not responding to gonadotropins, the dose may be increased. The goal is to achieve one or more mature follicles and an appropriate estrogen level, so that ovulation can be triggered by an hCG injection. You have to take the HCG injection for rupture and release of egg.

Normally about 30-40 follicles will start growing in response to the FSH produced by the pituitary. The dominant follicle releases increasing amounts of estrogen as it grows bigger and 32 to 36 hours after the onset of this LH surge, the dominant follicle releases (ovulates) its egg.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
