Imagine a world where we have sex exclusively for the fucking fun of it, and not to make babies.

It could come sooner than you think, if Professor Carl Djerassi is to be believed.

Djerassi, the Austrian-American chemist credited with inventing the contraceptive pill, believes that by 2050, sex will be purely recreational, and that men and women will freeze their eggs and sperm while young before being sterilized. Essentially, most of the babies in the world would be born through in vitro fertilization.

Additionally, Djerassi, 91, believes abortion practices will end, since no children will be unplanned or unwanted, according to The Telegraph.

Progress in IVF technology will give rise to a generation who are safe in the knowledge that parenthood can be delayed without repercussions, Djerassi says.

“The vast majority of women who will choose IVF in the future will be fertile women who have frozen their eggs and delayed pregnancy,” he says. “Women in their twenties will first choose this approach as insurance, providing them with freedom in the light of professional decisions or the absence of the right partner or the inexorably ticking of the biological clock.”

In other news, Djerassi believes a male contraceptive pill is unlikely because it would take far too long to prove there would be no impact on sperm quality. So for now, keep wearing condoms, or pulling and praying, etc.
