Oocyte or egg donation is one of the types of assisted reproductive technique (ART). It is basically a scenario where a woman donates her eggs to another woman for her to be able to conceive. Or, the technique is adopted in cases of poor quality or quantity of the oocyte or the egg. This could be due to premature or age related ovarian failure, as mentioned, poor ovarian reserve (due to advanced age or disease), implantation failure or recurrent abortions. Sometimes, egg donations is carried out to prevent genetic disorders. With more women delaying motherhood, necessity of egg donation has increased.
Egg donation is used in combination with IVF for better results. Results are also good when the donor whose eggs are being utilized is below the age of 35 years, as it is believed to result in higher pregnancy and implantation rates. Egg donation can also be utilized in various ways – fresh embryo transfer, frozen oocytes, frozen embryo transfer, autologous oocytes etc. Oocyte donation also works wonders along with GIFT, ZIFT, TEST and others.
As a procedure carried out in conjunction to IVF, the steps of pre-IVF apply to egg donation as well.
