Ugh look, a woman cannot become a space marine because the gene-seeding process is intedned soley to work with the hormonal balances and imbalances of a pre-pubecent male. The changes are supposed to happen in a body with those specific hormonal changes, using the adolcent body as a construction site for the changes needed to turn a human being into a post human Astartes. The process was not made with the female body in mind, and therefore to try it on a woman would require changing the entire process and how the gene-seed reacts with the host body. In short you would need to devise a totally new process, and remember what happened when the Imperiums best and brightest just tried to vaugely tweak the gene-seed? Cursed 21st.

Even then, I don't see what the big deal is, taking in the usual attrition rates suffered by Space Marine Asperaints and Neophytes, not to mention the casualty rates of the Scout core, its unlikely you would even remotely double the rate of recuitment in any Space Marine chapter.

Even Bile, ambitious as he is, would not waste time with Female Marines because there is no benifit to it, all of his work has been based off the groundwork set by the Emperor when he made the very first Legionaries and the Primarchs, to devise a whole new system from essentially scratch for basically the same result is absurd and has no profit.

In short, Female Space Marines, even if they were possible, are completly pointless and would provide only a marginal advantage. Besides, theres always the much cooler Sisters of Battle, who do all the shit Space Marines do without the blood of demi-gods in them.
