A study in humans demonstrated that the miR-10a-5p exhibits semen specificity and high abundance in normal semen [Tian et al. DOI:10.1016/j.fsigen.2017.12.010], and another comprehensive human study confirmed it displays distinctly higher expression levels in semen compared to other body fluids [Sauer et al. DOI:10.1016/j.fsigen.2016.01.018].
