Years ago the crassly utilitarian Fletcher — who has been called the “patriarch of bioethics” –swooned at the prospect of males giving birth in his 1988 book The Ethics of Genetic Control:
[T]ransplant or replacement medicine foresees the day, after the automatic rejection of alien tissue is overcome, when a uterus can be implanted in a human male’s body—his abdomen has spaces—and gestation started by artificial fertilization and egg transfer.
Hypogonadism could be used to stimulate milk from the man’s rudimentary breasts—men too have mammary glands. If surgery could not construct a cervical canal the delivery could be effected by a Caesarean section and the male or transsexualized mother could nurse his own baby.
It was a classic “it will never happen” argument. Nobody took it seriously. But once again, we find that if radicals envision it, eventually we will try to go there.
