Function[edit] Main article: Spermatogenesis Spermatogenesis, the process for producing spermatozoa, takes place in the seminiferous tubules. During spermatogenesis, the DNA of spermatogenic cells in the seminiferous tubules is subject to damage from such sources as reactive oxygen species.[1] The genomic integrity of spermatogenic cells is protected by DNA repair processes.[2] Deficiencies in the enzymes employed in these repair processes may lead to infertility.[2]
