at the very least you'd have to let the blastocyst implant somewhere, and there's a complicated molecular handshake going on

that and you'll need ova; but honestly once we have enough knowledge to tackle this we could probably induce parthenogenesis much easier

meaning it'll more likely to spell doom for men than for women ;P

apparently since the last time I read about this, we've found a way to create human embryos through parthenogenesis en.wikipedia.org/wiki/Parthenog

this comes with a huge huge disclaimer that these embryos are more likely cannot be carried to term than can. but it's a prerequisite

(currently looking through follow-up papers on that to see if something got lost in translation...)

yeah, they're both easily obtainable in mammals and completely useless if your goal is a viable fetus, eg [1-17] in ncbi.nlm.nih.gov/pmc/articles/P

tl;dr of sci-hub.cc/https://linkin: viable embryo requires specific epigenetics from both the egg and the sperm; 46,XX from egg alone...

results in an ovarian teratoma, 46,XX from sperm alone in a hydatidiform mole (do NOT google it); loss of epigenetic inhibitions results…
