Problems solved by technology

[0008] The detection box for detecting sperm chromatin in the prior art has the following disadvantages: 1) the composition is complex, consisting of 3-4 components, wherein each component is prepared from a variety of reagents, and the experimental steps in the detection process are cumbersome and costly. 2) can not be detected by flow cytometer
Most of the existing products can only be stained and observed through a fluorescent microscope, only the number of sperm nucleus fragments can be observed, and the degree of fragmentation and the proportion of immature sperm cannot be analyzed; 3) Even if the existing products can be detected by flow cytometry However, there are many components in the product, the sample processing is complicated, and the subsequent data analysis can only be carried out by its unique software, which cannot be analyzed by conventional flow software

Abstract

A sperm chromatin structure detection kit and application thereof are provided. The kit includes an A reagent and a B reagent, with the A reagent including HCl, Tween-20 and a phosphate buffer solution, and the B reagent including acridine orange and water. The kit is used in human sperm chromatin DNA staining to determine the chromatin DNA fragmentation level and to calculate the ratio of spermswith DNA fragmentation, and can analyze the ratio of immature sperms through the degree of combination between chromatin and protein.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a sperm chromatin structure detection kit and its application. Background technique [0002] The latest World Health Organization statistics show that among married couples, the average incidence of unwanted infertility is 7%-46%, and it is increasing year by year. Half of the causes of infertility are caused by male factors. Clinically, male infertility is divided into two categories: sexual dysfunction and normal sexual function. The latter can be further divided into azoospermia, oligospermia, asthenia Spermia, asthenospermia, and normal sperm count infertility. The degree of sperm DNA fragmentation is considered to be a new indicator for evaluating semen quality and predicting fertility. Male infertility patients have significantly increased sperm DNA fragmentation, and the integrity of sperm DNA is an effective basis for judging sperm quality. The degree of sperm DNA frag...
