Fertility and virility were a serious deal for those Egyptian elites. The Victorians would lop off the penises of the male statues and cover the nude women. Apparently, this came about because the royals were so inbred by the time Tutankhamen came around that they would do insane things to try and get an erection because they had developed a variety of adverse hereditary physical conditions due generations of inbreeding.

Tutankhamen's predecessor, Aten Neferneferuaten, and his suspected father, Akhenaten, were both physically deformed men oftentimes with reliefs and statues made to have bodies that more closely resembled a woman's than a mans. However, it could also be argued that during this time, psychotic women suffering sexual dysphoria were in charge of Egypt and they demanded to be documented as males, despite actually being female. All around, these were weird people. It's a good thing that their civilization is among the sands of time.
