METHOD FOR EVALUATION OF STALLION SPERM QUALITY BY DIHYDROTESTOSTERONE CONCENTRATION IN BLOOD SERUM Russian patent published in 2024 - IPC A61D19/00 G01N33/49 G01N33/50

Abstract RU 2823683 C1

FIELD: veterinary science.

SUBSTANCE: invention refers to veterinary medicine, namely to laboratory diagnostics, and can be used for selection of stallions with high sperm quality. Concentration of dihydrotestosterone in blood serum is determined. If the concentration of dihydrotestosterone in blood serum is higher than 362.5 pg/ml, the stallion is referred to a group with high quality of sperm. If concentration of dihydrotestosterone in blood serum is less than 362.5 pg/ml – to a group with low quality of sperm.

EFFECT: method enables to determine the quality of stallion sperm, without the need to know the total number of sperm cells with progressive mobility in the ejaculate, which in turn makes it possible not to recourse to sperm sampling.
