A biological male can take hormones, surgically alter his body and identify as “female,” but the procedures still won’t make him a woman, according to new evidence found by Israeli researchers.

That’s because there are at least 6,500 genes that contain sex-specific instructions for males and females.

For the study by Israel’s Weizmann Institute of Science, professor Shmuel Pietrokovski and Dr. Moran Gershoni, both researchers from the institute’s Molecular Genetics Department, “looked closely at around 20,000 protein-coding genes, sorting them by sex and searching for differences in expression in each tissue. They eventually identified around 6,500 genes with activity that was biased toward one sex or the other in at least one tissue, adding to the already major biological differences between men and women.”
