pump a woman full of testosteroine and you might get to males, however oyu already got males.

2. astartes are generally the creme of the crop of the avcailable material, hence a strong and agile woman would still be found wanting in direct comparison to male competition.

3. culture has also a very strong impact

4.empi, aka the most knowing holy leader did not use females for whatever reasons he had. you tihnk that anybody, who always has less of a grasp of gene seed (fabius is worse as he normally has access to mutated stuff in the first place ^^) so the amount of engineering possible is limited and you do not have the primarch material availabvle either.

aka: nobody availablew has tghe grasp to actually do somehting about it. when mariners operated on it,l they generally failed, the mechanicum created the cursed founding and bile  created the bloodfiends.(bear in mind that he has no access to undiluted primarch dna)

5. Sexc is probably not the issue as space marines are simply not capable of being romanticcally interested in females nor are their organs acxtually able to procreate, which is the main drive behind sexual activity ...
