22 out of the 23 pair chromosomes are exactly the same, with the last pair of chromosomes XY, only 1 of the pair differs. In fact, mostof the pysiology of a male and femaleis the same corresponding the hormone triggers, only  differe is the pelvic bone and reporuction organ. bonstructure would not matter much, and space marines are heard to be sterile yet the emperor's greatest fear of spacemarines being ableto reproduce and being about to create a new human subspecies. Thus you can say spacemarines are not sterile by this logical fear. Hormone treatment and extra organs would not harm a female physiology just as it would a male physiology, granted they may lose their breasts or sexual reproduction in assuming that allspacemarines are sterile. The fact in present that, 2k in years we can switch between genders with hormones seemlessly shows 40k years from now the tech is there, however the policies in place would make it heretical in the eyes of the imperium as it would or can lead to spacemarines sub species that could view regurlar humans as pests, furthermore, somespace marine chapters already ahve this problem. Thusly, a Tzteetch/Slaanesh warband could experiment witht his idea for science/pleasure/etc. A losing imperial sector/ failing spacemarine chapter lacking male troops in a certain area may have their apocaries use femalebodies to becomechapter members under protection of a inquistor that notonly approvesof the research to bolster forces but have even power and weight to force other inquistors to not call down extermiata.
