Egg donation is already fraught by ethical dilemmas. The current policy is to "compensate" young egg donors no more than $10,000 for the process of donating her eggs, although private agencies and tissue brokers will often offer more if a woman's eggs are deemed very desirable. That is, eggs of women with a certain height, weight, hair and skin color, IQ, college and college majors, ethnicity, religion, musical talent, athletic ability, hobbies, etc are worth more than other eggs. Unlike sperm donors, women who donate their eggs often do so under a "closed policy" -- ie, they are not allowed to know what happens to their eggs, nor the identity of any children that born from them.
Wouldn't adding mitochondrial donation only exacerbate the current situation?
