In a natural cycle, follicle stimulating hormone (FSH) causes follicles to grow in the ovaria. FSH is produced by the brain and released into the blood. FSH is administered through subcutaneous injections (underneath the skin). These injections are Gonal-F injections.
At cycle day 3 you start with the Gonal-F injections. You inject yourself between 16:00 - 20:00h each day. You continue with the injections until the doctor tells you to stop. At each ultrasound you will hear which dosage you need to use. Usually there is an ultrasound every 2-3 days, so we can determine the exact time you need to use the Ovitrelle injection.
