Notwithstanding the — ludicrous — choice of fictional hill to die on, in both the 40K universe and this one women and men (and, indeed, the intersex and the transex, which are not the same thing, BTW) have essentially the same genes and endocrine systems, hence why the author can accept their wife’s kidney or virtually any other transplantable organ (assuming, very generously, that the author can has a wife). Additionally, and for the nerds amongst us more importantly, nowhere in the lore — and I started back in the Rogue Trader days — are the gene-seed organs depicted as actually being in either the testicles or immediately surrounding the urethra.
