A study of late abortions by the Royal College of Obstetricians and Gynaecologists made possible estimation of the number of abortions carried out for various types of confirmed congenital defects at or after 20 completed weeks of gestation. A reduction in the legal age of fetal viability to 24 weeks, in the absence of any other change in practice, would have stopped an estimated 26 abortions for confirmed serious fetal defects other than anencephaly in 1982; a reduction to 22 weeks would have stopped 77 such abortions.
皇家妇产科学院对晚期流产进行的一项研究，使得估算在妊娠满20周及以后因各种确诊的先天性缺陷而进行的流产数量成为可能。在实际操作没有任何其他变化的情况下，将胎儿存活的法定孕周降至24周，估计在1982年可避免26例因确诊的严重胎儿缺陷（不包括无脑儿）而进行的流产；降至22周则可避免77例此类流产。
