Abstract:

Spermiogenesis is the final stage of spermatogenesis, in which round spermatids differentiate into mature sperms through a complex process including morphological changes and chromatin condensation. Histone-to-protamine transition during spermiogenesis is a critical part of this biological process. Histones are initially replaced by testis-specific histone variants, then transition proteins integrate into the nucleus, and are in turn replaced by protamine. Impaired histone-to-protamine transition may cause azoospermia, oligospermia or teratospermia, which lead to male infertility. In this review, we summarize the research progress of regulatory mechanisms of the histone-to-protamine transition, thereby providing the theoretical basis for the diagnosis and treatment of male infertility.

Key words: spermiogenesis, histone-to-protamine transition, post-translational modification
