Sperm Chromatin Integrity Disturbances in Infertile Men
Poruchy integrity chromatinu ve spermiích infertilních mužů
Cíl studie:
Přehled poznatků a metod detekce v oblasti poruch integrity chromatinu spermií.Typ studie:
Literární přehled.Název a sídlo pracoviště:
Výzkumný ústav veterinárního lékařství, v.v.i., Brno.Předmět a metodika studie:
Přehled zkušeností s metodami zjišťování poruch integrity chromatinu ve spermiích mužů.Závěr:
Porucha integrity chromatinu ve smyslu přítomnosti zlomů v DNA a defektní kondenzace jádra spermie je jedna z příčin mužské infertility. Existuje mnoho přístupů k detekci těchto poruch. Metody se liší především rychlostí proveditelnosti, finanční náročností a vypovídací schopností. Práce přináší přehled nejčastěji používaných přístupů, snaží se porovnat výhody a nevýhody jednotlivých metod.Klíčová slova:

Overview
Objective:
A survey of knowledge and detection methods of sperm chromatin integrity disturbances.Design:
Review of literature.Setting:
Veterinary Research Institute, Brno.Methods:
A survey of experience with detection methods for human sperm chromatin integrity disturbances.Conclusions:
Disturbed sperm chromatin integrity manifested as an increase in DNA strand breaks within the spermatozoa and deficient chromosome condensation in the sperm nucleus is one of the causes of male infertility. Various approaches to the detection of such defects have been described. The methods differ above all in the time and expenses required, and robustness. The review brings a survey of the most commonly used procedures, and compares advantages and disadvantages of respective methods.Key words:
