title: [Premature condensation of sperm chromosomes in human oocytes fertilized in vitro].
abstract: Analysis of the frequency of oocytes containing premature condensed sperm chromosomes depending on clinical and embryological parameters has been carried out. It was shown that this frequency comes to 11.6% during in vitro fertilization and depends on morpho-functional characteristics of acnipo[symbol: see text] oocytes.
