We recently described a complex population of spermatozoal coding RNAs that are delivered to the oocyte on fertilization. These are derived throughout spermatogenesis, representing a record of past events. Recently, evidence has been provided that micro-RNAs are present in testes, suggesting that they might also be carried in ejaculate spermatozoa. To directly test this hypothesis, a unique microarray system capable of directly identifying antisense RNAs and predicted transcripts was utilized. RNA isolated from the ejaculate spermatozoa of 6 normal fertile men was directly hybridized to sense oligonucleotide arrays containing 10000 elements. This revealed 68 shared RNAs, some of which are similar to those previously defined as micro-RNAs, whereas others were the antisense of previously in silico-predicted transcripts. The results and implications of this study are described in this communication.
