IVF laboratoryClick one of the following links: sperm analysis motility morphology WHO recommends that each laboratory recruits fertile men (a reference population) in order to investigate and determine the real cut-off values for normality in that laboratory (28). These men are very difficult to recruit, therefore only a few laboratories actually perform this analysis (3). During the past 15 years there has been an increase in total motile sperm count, secondary to an increase in semen volume, and a decline in normal morphology. Both are independent of the age and the duration of abstinence in fertile men (5). There is a debate on this subject and some of the arguments discussed by different authors are the analyze techniques used by laboratories and the influence of environmental factors on sperm morphology. A number of authors, under in vivo conditions of conception, have demonstrated that the pregnancy rate was significantly higher in cases of better sperm morphology (13). But, particularly under the usual in vivo conditions of conception, pregnancy rates are influenced by a multiplicity of different parameters. It seems that sperm morphology evaluated for strict criteria has definitive advantages over the other (liberal) criteria evaluation methods in the prediction of in vivo and especially in vitro fertilization rates (22). Other publications’ unavoidable conclusion is that sperm morphology according to WHO classification can be a vigorous predictor of IVF outcome (24). Therefore, further investigations of semen morphology and male fertility according to WHO may be clinically rewarding. There are papers which emphasize the importance of inclusion of abnormalities in the acrosomal region during sperm morphology assessments and suggest that previous emphasis placed on sperm head dimensions in the classification of normality is justified only in cases of extreme deviation of the normal (12). Neither abnormal sperm concentration, nor abnormal sperm morphology are significantly associated with recurrent spontaneous abortion (14). spermanalysis motility morphology analyzer animal breeders clinics equine laboratory labs management reproductive research screens software species speed swine system toxicology assessment insemination program quality semen stallion veterinary acquisition automatic concentration data estimation image images measure parameters statistical video videotest windows accurate advanced analyzed assisted reproduction casa computer diagnostic fertility infertility laboratories male study database distribution motile movement spermatozoa IVF track spermiogram moving tracking WHO tracker sperm_11 analysis_11 motility_11 morphology_11 computer aided sperm analysis: automatic analysis of sperm motility and morphology for assisted reproduction, veterinary research and toxicology sperm analysis motility morphology analyzer animal breeders clinics equine laboratory labs management reproductive research screens software species speed swine system toxicology assessment insemination program quality semen stallion veterinary acquisition automatic concentration data estimation image images measure parameters statistical video videotest windows accurate advanced analyzed assisted reproduction casa computer diagnostic fertility infertility laboratories male study database distribution motile movement spermatozoa IVF track spermiogram moving tracking WHO tracker © |
