Androgens are key for pubertal development of the mammalian testis, a phenomenon that is tightly linked to Sertoli cell maturation. In this review, we discuss how androgen signaling affects Sertoli cell function and morphology by concomitantly inhibiting some processes and promoting others that contribute jointly to the completion of spermatogenesis. We focus on the molecular mechanisms that underlie anti-Müllerian hormone (AMH) inhibition by androgens at puberty, as well as on the role androgens have on Sertoli cell tight junction formation and maintenance and, consequently, on its effect on proper germ cell differentiation and meiotic onset during spermatogenesis.
雄激素是哺乳动物睾丸青春期发育的关键,这一现象与支持细胞成熟密切相关。在这篇综述中,我们讨论了雄激素信号如何通过同时抑制一些过程和促进其他过程来影响支持细胞的功能和形态,这些过程共同促进精子发生的完成。我们重点讨论了青春期雄激素抑制抗苗勒管激素(AMH)的分子机制,以及雄激素在支持细胞紧密连接形成和维持中的作用,以及由此对精子发生过程中生殖细胞分化和减数分裂起始的适当性的影响。
