UK Women Limited to One Embryo

British women trying to get pregnant via In Vitro Fertilization will be limited to having one embryo implanted at a time, in a move by the government to stem the surge of problematic multiple births, the Guardian reports. Only women with particularly low chances of conception will still be allowed to have multiple embryos implanted via IVF.

The rationing will prove controversial because it will reduce the chances of success for women undergoing the costly treatment. Some doctors are also likely, the Guardian adds, to protest the move as an intrusion into their right to decide the best course of treatment for their infertility patients. But most mainstream fertility organizations in Britain have backed the policy. (More Britain stories.)
