By the way, since alcohol is promoted by society, where's my government ration? No one told her to put that many embryos back, or to have sex when 6 follicles were seen. A respectable fertility doctor would skip that cycle.
Respectable Reproductive Endocrinologists who do an IVF procedure do not put back any more than 3 follicles. All of which or some of which MAY split. Thus, still leaving several babies!
Also, most people who are going through fertility treatment aren't just having sex at conception...many are also having iui (intrauterine insemination).
