英国发展一种新技术,不通过体外受精(试管婴儿)而使无子女的夫妇得有子女,且避免了关于道德问题的许多抨击。这项技术虽在发展中的早期阶段,但已有两例妊娠,看来进展满意(《Lancet》1982;1:1031.)。 Patrick Steptoe和Robert Edwards首创的常规技术是由母体取出未受精的卵,在培养皿上使卵子受精。将胚胎于数天后再重新植入母体子宫内。由伦敦皇家福利医院的Ian Britain developed a new technology that allowed children without couples to have children through in vitro fertilization (IVF) and avoided many of the criticisms of moral issues. Although this technique is in the early stages of development, two pregnancies have been observed and progress seems satisfactory (Lancet 1982; 1: 1031.). A common technique pioneered by Patrick Steptoe and Robert Edwards is to remove unfertilized eggs from the mother and fertilize the eggs on a Petri dish. The embryo is replanted into the mother’s uterus after a few days. Ian by London Royal Welfare Hospital
