Brief introduction
Semen analysis is the most basic and supreme examination method for judging and evaluating male fertility.with the rapid development of reproduction medicine,the request for a consensus opinion for the objective determination of all semen parameters and its standardized has also been strengthened.Though the World Health Organization(WHO) has published for many times the human semen inspection handbook,aiming at promoting the normalization and standardization of this iespection, the traditional man-made semen analysis method is affected by many factors such as laboratory condition and the experience of technicians.therefore it is hard to achieve goals.
As being affected by many factors,nowdays the clinical used human semen analysis method has difficulty in accurately and objectively inspecting all parameters,especially the analysis of sperm motility rate and activity,which is in large degree depended on the experience and subjective judgement.semen automatic analysis system can effectively ocercome the above shortcomings.By adopting micro camera,computer can quickly analyze the sperm running locus and speed in many vision fields.through the clinical application of authority departments such as the third affiliated hospitals of Peking Medical University, the chinese people '''' s liberation army general hospital,national reproductive center,it is thought that sperm automatic inspection analysis system uses the modern computer technique and advanced image processing system in the analysis of sperm quality,and the results showed that this detecting system had good reproducibility and detecting results consistency under different enlargement factor.In clinical inspection,comparing with classic man-made detecting method ,its sperm density, motility rate and A+B vigor percentage parameter have good correlation.what’s more,semen automatic analysis system can record aperm movement locus in three seconds,and its movement locus graph can reflect sperm''''s true movement condition and provide convenience for clinical detection and researchers'''' teaching and training.The analysis system has high reproducibility、good comparability、easy operation,can reduce the error of human operation and print、store、inquest report so that it can offer convenience for clinical and research comparison and analysis.The application of sperm automatic detection and analysis system creates condition for the scientization、normalization and standardization of clinical and research semen normal analysis.
