So, I am borrowing this concept from Krypton which most of you are familiar with as Superman's homeworld. I will go into a bit of an explanation here. Kryptonians didn't reproduce or carry babies, a couple would put thier dna into a big machine which housed artificial wombs and then randomly decide the sex. No sperm or eggs needed. They wouldn't get pregnant considering females would have their fallopian tubes cut and stuff. It was a part of population control.

Now, the part here is if we reach such technology. The women would not have the risk of getting pregnant which means they would be willing to open up more. The pregnancies would be planned. Same sex couples would be able to have babies. How else would this effect the dating market?
