That’s like when people were going around saying that white people had higher facial symmetry then other races, because those with higher facial symmetry were deemed more attractive. Then it was found that genetic diversity and being more heterozygous gave one more facial symmetry. Black Africans were found to be more genetically diverse then all other continents combined, even within small obscure communities, which would mean they have higher facial symmetry but I guess this testosterone fallacy is the new racist ideology to latch on too
If testosterone deficiency occurs during foetal development, then masculinisation of the foetus will fail to occur normally and this may give rise to disorders of sex development. If testosterone deficiency occurs during puberty, a boy’s growth may slow and no growth spurt will be seen. The child may also fail to develop full sexual characteristics (hypogonadism) associated with men undergoing puberty, including development of pubic hair, growth of the penis and testes and deepening of the voice. Around the time of puberty, boys with too little testosterone may also have less than normal strength and endurance, and their arms and legs may continue to grow out of proportion with the rest of their body.
