Using donor eggs has become a widely accepted and increasingly popular option for individuals and couples facing infertility. This process involves the donation of eggs from a healthy, screened donor to a recipient whose own eggs may not be viable for conception. Donor eggs offer a high success rate for achieving pregnancy and provide hope and a potential pathway to parenthood for many who might not otherwise have the opportunity. Choosing Donor Eggs and Embryos
Most couples explore other fertility options using their own eggs and sperm before considering donor eggs or embryos. This method requires synchronization of the donor's and recipient's menstrual cycles to ensure the recipient's body is ready to receive the embryo at the optimal developmental stage.
The Process of Egg Donation
Egg donation involves several steps:
Synchronization - The recipient's cycle is synchronized with the donor's cycle, starting a month before the embryo transfer. This typically involves a set of injections and pills.
IVF Procedure - The egg donor undergoes hormone stimulation to produce multiple mature eggs, which are then retrieved and fertilized in the lab.
Embryo Transfer - The fertilized eggs (embryos) are transferred to the recipient's uterus. The recipient can also be prescribed progesterone to support the pregnancy.
Sources of Donor Eggs
Donor eggs can be obtained through fertility centers or donor agencies:
Anonymous Donors - These donors are typically found through advertisements in media or the internet. They undergo rigorous screening for health, genetic history, and psychological fitness. Donors are compensated for their contribution.
Known (Directed) Donors - These donors are often family members or friends, providing a genetic link. Known donors also undergo screening for infectious and genetic diseases, and their medical costs are covered by the recipient.
Donor Embryos
Using donor embryos, also known as embryo adoption, is an option for single women or couples unable to use their own eggs or sperm. There are two main pathways:
Preexisting Embryo Donation - Embryos donated by genetic parents are transferred to the recipient. This method is less common due to the limited availability of donated embryos.
Creating Embryos - New embryos are created using donated eggs and sperm. This allows more control over the genetic material but is more costly and complex.
Recipients of donor embryos might also undergo psychological screening to assess readiness for raising a child not genetically related to them.
Chances of Success
The success rate of pregnancy and live birth using donor eggs largely depends on the donor's age. Donors are usually under 35, resulting in high success rates. According to our data, about 60% of cycles using donor eggs result in a live birth. Frozen embryo transfers have a success rate of around 42% for women under 35.
Using donor eggs and embryos offers a viable pathway for individuals and couples struggling with infertility. Despite the complexities, the high success rates and growing availability of donor services provide hope and opportunities for many potential parents.
