When the Emperor created the necassary geneseed and organs for space marine, he didn't create them for females in mind. If a geneseed can fail in men most of the time, what makes you think that it work in a female. Also, I know that some people will say that chaos apothacaries can manipulate the geneseeds, but they can't. The only person who knows how to create and manipulate geneseeds correctly is the Emperor and he is currently a mummified husk. Another thing is that you can create any knew geneseed, since the knowledge needed to create new geneseeds was lost over time.

IRL genetic and endocrinology well mostly genetics would like a word with you. Namely Female DNA is more stable than male DNA, check it out a lot of genetic conditions are mostly or exclusively male.. So if we going by that logic a Geneseeds that have potentially have mutation would probadly stabilize

Won't survive multiple implantation of organs. Women grow multiple additional human beings on a fairly regular basis, so  stuffing organ in isn't that big of a problem.

So In universe explaination is just hurr durr because reason.
