One possible pathophysiologic explanation of intersex in humans is a parthenogenetic division of a haploid ovum into two haploid ova. Clinically, medicine currently describes intersex people as having disorders of sex development, a term vigorously contested. "High local genetic diversity and low outcrossing rate in Caenorhabditis elegans natural populations". 34 This is technically not true. The distribution of self-fertilization rates among animals is similar to that of plants, suggesting that similar processes are operating to direct the evolution of selfing in animals and plants.
Before this stage, humans are simply undifferentiated and possess a Müllerian duct, a Wolffian duct, and a genital tubercle. Although they possess ovaries and testes, they have a protective mechanism against self-fertilization.
