Morphological and functional disorders inserts sperm mitochondria , which are more often the cause of male infertility ( astenoteratozoospermii ) can be identified using a precise diagnosis of mitochondrial insert sperm .

Sperm Mitochondria are structures unique and slightly different from somatic mitochondria . They undergo a series of morphological , biochemical and molecular changes associated with the expression of specific structural and enzymatic proteins , which are markers of maturation during spermatogenesis. These include , among others, gonadalny cytochrome cT , LDH - C4, sulfhydryl oxidase , protease LON and hsp60 . Activin A secreted by Sertoli cells when spermiogenezy mitochondria induces morphological changes spermatids , leading to the formation of condensed structures of these organelles.
