Metabolite annotation of rat epididymis with High-resolution imaging mass spectrometry

Infertility or subfertility is a widespread problem with approximately 25% of couples seeking medical help. For about half the cases it lies in the male partner. Male infertility is caused by problems that affect sperm production, maturation and/or transport. In this study the role played by the epididymis in the post-testicular maturation of spermatozoa during its transit through this organ was investigated using FT-ICR imaging mass spectrometry of metabolites and the FDR-controlled metabolite annotation platform MetaSpace for high-resolution imaging mass spectrometry. This study together with MTBLS313 provides the accompanying data for FDR-controlled metabolite annotation for high-resolution imaging mass spectrometry.
