  • Method of Diagnosing Asthenozoospermia
    Publication number: 20100151498
    Abstract: After sampling semen from healthy males and from patients whose chief complaint was infertility, the semen volume, sperm concentration, sperm motility rate, and sperm survival rate in each of the specimens were measured, sperm-bound SPMI was detected using an anti-SPMI antibody, and the amount and rate of SPMI binding were calculated. As a result, only patient specimens were found in the specimen group with amount and rate of SPMI binding above a certain level. Diagnosis of asthenozoospermia can be made by determining the amount and rate of SPMI binding.
