The Wall Street Journal reports that, in IVF and even surrogacy treatments in the US, fertility clinics regularly ignore guidelines about multiple embryo implantations, resulting in far higher multiple births (and the increased risks and complications that go with it.
The reasons, in order of appearance: near-non-existent fertility clinic regulation ["they're really more guidelines than codes."]
pushy parents demanding successful implantation [um, maybe they're pushy because they have to pay the whole thing themselves? Heaven forbid the WSJ points to an argument in favor of a national health care plan.]
competitive clinics gunning for the highest success rates [cuz it's so lucrative, see.]
all those "bad embryos" [no joke here, sorry.]
