I can only offer 2nd hand knowledge. I work with a lot of [name]ART[/name] patients, and some of the couple use donor eggs. I have only worked a few times with the actual donors. There are only a couple of things I can think of to bring up for you to consider.
If it were me donating, I think one of my biggest concerns would be my drug protocol I’d be given. Clinics and doctors have gotten much better over the past few years, but one of the biggest dangers as a donor is ovarian hyperstimulation. This is when the drug protocol stimulates the ovaries too much, creating an abundance of follicles and fluid in the ovaries. The ovaries become very enlarged. Symptoms range from mild to severe. Severe cases are very rare, but can be life threatening. Most cases are mild and mainly involve discomfort, bloating, and some nausea. The more severe end of the spectrum involves fluid in your abdominal cavity, breathing difficulties, and kidney problems. Ovarian hyperstimulation is most often seen in a typical IVF patient who becomes pregnant during her cycle following the ovarian stimulation and retrieval because the pregnancy hormone hCG compounds the issue. Since you’d be a donor and will not become pregnant, this situation wouldn’t pertain to you. However, because you’re young, and probably have very responsive ovaries, it is something to consider. A reputable clinic, with skilled RE’s should also decrease the risk of this. There are clinics, though, that try to harvest as many eggs as possible, and that’s when problems can arise.
The other question: Would this be an anonymous donation? For me, the most difficult part would not be the physical discomfort and pain from the injections into my abdomen or butt, the stimulation of my ovaries, and the retrieval of my eggs. The most difficult part would be to donate my eggs to anonymous couples. I’d be much more comfortable knowing the people who’d be using my eggs to create a family. I would hate to help a couple create a family who had vastly opposite political, religious, spiritual, social, and child-rearing views that I have. I think that would cause me the most distress. No amount of financial compensation could make up for the pain I’d feel not knowing what type of life those children born from my eggs were going to have. If it’s anonymous you need to assume that anyone from a same-sex couples to right-wing tea partiers could be using your eggs.
I will say, though, that in my experience, all of the couples that have used egg donors have been very lovely people (from what little I know about their lives). Couples that end up using egg donors have usually exhausted all other options in their long and painful road of infertility. They are usually very passionate about becoming parents, are financially secure, educated, and all about being the very best parents they can possibly be. It is truly a wonderful gift you can offer to a desperate couple. And, you will be financially compensated, sometimes quite generously.
I hope that helps a little bit. Best of luck. I’d be very curious to hear what you decide.
