FIELD: medicine.
SUBSTANCE: technique is implemented by determining abnormal chromatin packaging by its availability for hydrolysis by micrococcus nuclease. The technique is based on quantitative estimation of an intensity of chromatin hydrolysis by micrococcus nuclease. Chromatin hydrolysis is followed by dividing a hydrolysate material on 2 fractions: soluble chromatin and insoluble chromatin. A check value is a nature of chromatin hydrolysate of donor sperm cells characterised by the regular spermogram values.
EFFECT: improved clinical effectiveness in infertility within extracorporeal fertilisation and homologous insemination programs.
