Dr. Aarathi Prasad, author of a book about reproduction without men, muses on the possibility that Jesus was born to a virgin, but not a virgin with two X chromosomes.

Prasad argues that a virgin could give birth to a child, but no woman could produce a boy without the donation of a Y chromosome. In order for Mary to have given birth to Jesus, she would have had to have a condition called testicular feminisation, which would make her genetically male, but with the genitals of a woman. Unlike pythons, hammerhead sharks, and Komodo dragons, there has never been a documented example of a virgin birth in humans.
