A new Bayesian network-based approach to the analysis of sperm motility: application in the study of tench (Tinca tinca) semen.

abstract：:Spermatogenesis involves the aggregated action of up to 2300 genes, any of which, could, potentially, provide targets for diagnostic tests of male factor infertility. Contrary to the previously proposed common variant hypothesis for common diseases such as male infertility, genome-wide association studies and targeted...
