Some forms of infanticide in ancient societies, present-day reprogenetics, preemptive abortions and designer babies have been (sometimes controversially) referred to as eugenic.

古代社会的某些杀、当今的殖遗传学、抢先堕胎由设计者设计儿这些（有时是有议的）动都被称优。

However, some private organizations assist people in genetic counseling, and reprogenetics may be considered as a form of non-state-enforced liberal eugenics.

然而，一些给人们提供遗传咨询的私人机殖遗传学（利用遗传学技术来改变或控制殖过程）可被视某种形式的、非国家实施的自由主义优学。
