First of all "I" am not a sperm cell.
Secondly, cancers do very well in self reproduction with few limitations.
Thirdly, aside from parthenogenic activation...if you culture an egg (haploid #) with
blastomeres derived from a blastocyst..it will develop...apparently, the egg is able to
access the "needed" DNA from the diploid cells to activate itself toward development
(I'm vague on this work...but if you insist I will produce it for you). Therefore,
women don't need the opposite sex to reproduce, just a diploid cell (from another
female) to activate the egg.
