Once approved, donors undergo hormone treatments to stimulate their ovaries to increase egg production.
This process is similar to what women undergoing fertility treatments experience. Your age and healthy reproductive system work in your favor, so the process is well controlled, safe, and relatively straightforward.
Controlled Ovarian Hyperstimulation (COH)
The idea behind egg freezing is to try to harvest as many mature eggs as possible. Ultimate IVF success rates are dependent upon the number of the mature eggs and healthy embryos available for transfer. A woman undergoing egg freezing for donation is given fertility drugs for two reasons: (1) to enhance the growth and development of her ovarian follicles in order to produce as many healthy eggs as possible and (2) to control the timing of ovulation so that the eggs can be surgically retrieved before they are ovulated, with as many of them being mature as possible. In cases where the donor has previously received fertility drugs, the subsequent treatment regimen is largely based upon her most recent response to such treatment. For a woman receiving these ovarian stimulation medications (gonadotropins) for the first time, the dosage and regimen is determined by her ovarian reserve assessment (see above), medical history and body habitus.
In most cases, the woman begins her cycle of treatment by taking oral contraceptive birth control pills (OCP/BCP) for 6-30 days before initiating daily injections that may or may not include the following fertility medications.
