Developmental basis of male nipple loss and retention in mammals

2025-10-24

Abstract excerpt

<title>Abstract</title> <p>Most male mammals, including humans, have nipples, but a few male species, including mice, do not. It is currently believed that testosterone produced by the fetal testes during sexual differentiation causes nipple atrophy in male mice. However, since all male mammals produce testosterone during sexual differentiation, how nipples are retained in most male mammals, including humans, rem...
