Selective termination is the term used for the elimination of an abnormal fetus. In contrast, multifetal pregnancy reduction refers to the termination of one or more members of a twin or higher-order multiple birth set, respectively, to reduce the high risks associated with these pregnancies. The procedure can also be used when a serious physical condition is detected prenatally in a member of a multiple birth set. In a minority of cases, selective termination has reduced two healthy fetuses to one when parents wanted just one additional child in the family. In the present article, the perspectives of a surviving twin whose family wished to terminate both healthy fetuses are examined. Next, past and present twin studies of primordial dwarfism, public service motivation, an analytical model, the global twinning rate and germline differences are summarized. The article concludes with a synopsis of twin-related news that covers twins and Dyngus Day, triplets born in an Austrian displaced persons' camp, the film Superior - about estranged identical twin sisters, a couple adopting their own twins after surrogacy and a new case of twins and primordial dwarfism, a condition introduced in the research reviews.
选择性终止是指消除异常胎儿。相比之下，多胎妊娠减少是指分别终止双胞胎或更高阶多胞胎中的一个或多个成员，以降低这些妊娠的高风险。如果在多胞胎成员中产前发现严重的身体状况，也可以进行该程序。在少数情况下，当父母希望家庭中只有一个额外的孩子时，选择性终止已经将两个健康的胎儿减少到一个。在本文中，研究了一个幸存的双胞胎的观点，其家庭希望终止两个健康的胎儿。接下来，总结了过去和现在关于原始矮小症、公共服务动机、分析模型、全球双胞胎率和种系差异的双胞胎研究。文章最后概述了与双胞胎相关的新闻，其中包括双胞胎和 Dyngus 节、在奥地利难民营出生的三胞胎、关于疏远的同卵双胞胎姐妹的电影 Superior、一对夫妇在代孕后收养自己的双胞胎以及一对患有原始矮小症的双胞胎的新案例，这是研究综述中引入的一种情况。
