Study shows eggs may actively pick sperm
https://www.quantamagazine.org/choosy-eg...-20171115/

Not sure how well grounded this hypothesis is, but I have read that women's reproductive systems might reject sperm if they are not from a favored mate. That might explain why some couples have more trouble conceiving.

Quote:Random fertilization should lead to specific ratios of gene combinations in offspring, but Nadeau has found two examples just from his own lab that indicate fertilization can be far from random: Certain pairings of gamete genes are much more likely than others. After ruling out obvious alternative explanations, he could only conclude that fertilization wasn’t random at all.

“It’s the gamete equivalent of choosing a partner,” Nadeau said.

His hypothesis – that the egg could woo sperm with specific genes and vice versa – is part of a growing realization in biology that the egg is not the submissive, docile cell that scientists long thought it was. Instead, researchers now see the egg as an equal and active player in reproduction, adding layers of evolutionary control and selection to one of the most important processes in life.

RE: Study shows eggs may actively pick sperm
Fuck me, you're telling me female hypergamy even predates the zygote?

Waiting for first datasheet for sperm looking to bang an egg. "You have to open with a good negg, then escalate by showing off your ABCDE sequence."

Still, this is, amusingly, a way to trigger or derail an abortion SJW. "You say you're all about pro-choice, what about your eggs' right to choose Alpha sperm?"

Although an interesting theory, the obvious socio-political angle of the reporting reeks. I'm immediately skeptical when I see this blatant SJW language paraphrased into the lab work.

Next datasheets.

"How do I make my sperm more alpha?"

"My sperm swam right by the egg, is that beta?"

"My girl is pregnant with twins, does that mean my sperm is alpha or beta?"

I thought this was going to be about how eating eggs makes your sperm more alpha.

If you fuck an 18 year old girl without a condom and blast into her daily for 3 months she is getting pregnant no matter who you are.
