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

古代社会的某些杀婴行为、当今的生殖遗传学、胎和由设计者设计婴儿这些（有时是有议的）行动都被称为优生。

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，一些给人遗传咨询的私人机构和生殖遗传学（利用遗传学技术来改变或控制生殖过程）可被视为某种形式的、非国家实施的自由主义优生学。
