I think the many recent cases of mega-multiples in the news are probably more the result of implanting embryos rather than 'fertility drugs'. When my daughter (a nurse) was trying to get pregnant, she was given medications to promote ovulation. I asked her if she wasn't afraid of having a 'litter'! She wasn't worried about that at all. She said that actually multiples were very rare on the medications, and when multiples did occur, it was almost always just twins, not five or six.
But what doctor in their right mind would implant eight embryos in a single woman who already had six children at home! Some of these people who appear to be just barely making it financially, how do they do it? These treatments and procedures are ungodly expensive! I know they use multiple embryos to increase the chances of getting at least one live birth, but should there not be some 'ethics' involved there? Should they not draw the line at maybe three instead of taking the chance of six, or maybe even eight babies? For someone who has tried for years to get pregnant and then ends up with a multiple pregnancy, the decision to have or not have a 'reduction' must be agonizing!
