Caspar Bartholin, a 17th-century Danish anatomist, dismissed Colombo's and Falloppio's claims that they discovered the clitoris, arguing that the clitoris had been widely known to medical science since the second century. [145] Although 17th-century midwives recommended to men and women that women should aspire to achieve orgasms to help them get pregnant for general health and well-being and to keep their relationships healthy, [134] debate about the importance of the clitoris persisted, notably in the work of Regnierde Graaf in the 17th century [46] [146] and Georg Ludwig Kobelt in the 19th. [16] Spider and squirrel monkey societies are sex-segregated; males travel and interact in all-male groups, while females reject males and travel alone or only with their offspring.
