This study aimed to demonstrate the presence of erythropoietin (EPO) receptor on spermatozoa. Whole ejaculates of four healthy volunteers were incubated with polyclonal rabbit anti-EPO receptor and subsequently stained with a Cy-3 labelled secondary antibody. Four slides per subject were analysed, no staining was observed in slides incubated with either primary or secondary antibody alone. EPO receptor staining was positive in 92 ± 8% of EPO pre-treated and 91 ± 4% of non-treated sperm cells. The results suggest that spermatozoa express EPO receptor on plasma membrane, which might act to protect these cells from damage after ejaculation. © 2010, Reproductive Healthcare Ltd.
