Methods： Fluorescence in situ hybridization （FISH） was done on the sperm heads of six men before and during treatment by TCM. Results： There was a significant reduction in sperm disomy in all six men. This coincided with TCM treatment. Conclusion： This is the first study reporting a significant reduction in sperm disomy in men over a given time course. The fact that this coincided with TCM treatment is intriguing but no conclusions can be drawn from this until placebo-controlled clinical trials are implemented.展开更多

The major barrier is the operator time taken to analyze a statistically meaningful （sufficient） number of cells. The introduction of automated ＇spot counting＇software-hardware combinations presents a potential solution to this problem. In this preliminary validation study,we analyzed 10 patients,both manually and using a commercially available spot counter. Results show a statistically significant correlation between both approaches for scoring of sperm disomy,but no correlation is found when scoring for diploid sperm. The most likely explanation for the latter is an apparent overscoring of two closely associated sperm heads as a single diploid cell. These results,and similar further studies that will ensue,help to inform cost-benefit analyses that individual clinics need to carry out in order to decide whether to adopt sperm aneuploidy screening as a routine tool for the assessment of sperm from men requiring ICSI treatment.展开更多
