Characteristics of human semen by microscopic observation during liquefaction / 中华检验医学杂志

ABSTRACT

Objective To compaire the physical characteristics of semen morphology before and after semen coagulation-liquefaction under microscope and understand the significance of these characteristics for the determination of semen liquefaction.Methods Semens were placed in sperm counting chamber immediately after collection.The morphological changes of the seminal gelatinous substance during liquefaction were observed under microscope and analyzed.Results Morphological changes during semen liquefaction can be clearly observed.Among 32 samples of semen,forward sperm progression and motility were (30.3?12.4)% and (45.0?14.9)%,(44.9?12.7)% and (59.0?15.3)%,before and after the liquefaction,respectively.The differences were statistically significant (t=-1.130,5.023,P0.05).Conclusions Microscopic observation of the seminal gelatinous substance is a simple and feasible method for objective measurement of sperm liquefaction.These findings suggest it may provide pathological significance on semen liquefaction abnormality in infertility clinic.
