Brief Summary: Men are recruited to collect seminal plasma samples and serum samples from men with azoospermia, men receiving medical treatment of infertility and men attending semen analysis. MicroRNA (miRNA) and PiWi-interacting RNA (piRNA) are analyzed for all of the groups to find potential differences. Steroid hormones are analyzed by liquid chromatography-tandem mass spectrometry.
