5 days ago · This page introduces spermatogenesis the development of spermatozoa, the male haploid gamete cell. In humans at puberty, spermatozoa are produced by spermatogonia meiosis in the seminiferous tubules of the testis (male gonad). A second process of spermiogenesis leads to change in cellular organisation and shape before release into the central lumen of the seminiferous tubule.

A maturazione morfologica conclusa, lo spermatozoo deve andare incontro ad un'ulteriore maturazione funzionale in due fasi: la mobilitazione, che avviene nell'epididimo (nella gonade maschile) e permette agli spermatozoi di muovere il flagello, e la capacitazione, che avviene nelle tube uterine femminili e permette sempre agli spermatozoi di ...
