It fits with grooming our society to accept nonfertile woman.

One male offspring carries the gene defect to pass to the next generation. One male is regular. One female express as male and is infertile and one one female is regular. 3 outbif four express male.

Pin drop.

Thus the sperm is the intergenerational infertility vaccine.

I come from cattle farmers on my mom's side. There is no beef farmer that would ever want male bulls except for fertilizing the heifers. My grandfather kept one in a stall, that was so frightening. Just watch a rodeo.

No you will not create a farm of male bulls. They would kill each other. Even if you play Cher to them.

So the basis of creating this monstrosity in mammals is demonic.
