title: [Modifications of motility and respiratory activity of human spermatozoa following congelation in liquid nitrogen].
abstract: By using a polarographic technique it has been noticed that the respiratory activity of human sperms was increased after addition of cryoprotector medium to semen. But this activity was markedly reduced after freezing in liquid nitrogen. We suppose that freezing causes a damage of some metabolic structures of cells which affects more severely their respiratory activity than their motility.
