Abstract

A review of an unusual twin type—twins born to women with two uteri (uterus didelphys)—is presented. This review is followed by summaries of recent research and perspectives concerning prenatal aneuploidy screening for twin pregnancies, twin conceptions by same-sex male couples, legal personality of conjoined twins, and a twin study of cannabis use. Interesting information about twins that has appeared in the media is also presented, namely how being taken for twins saved a pair of sisters; twin children of a jailed Nobel Prize winner, British ‘biracial’ twins, triplets born at the start of Russia’s attack on Ukraine, and twins born in different years.
