Subsequent to the detailed analysis of several datasets obtained from the GEO omnibus for possible diagnostic biomarkers involved in different phases of spermatogenesis, and in overall male infertility, the following genes/proteins were identified (INPP1, ATG9A, CCDC96, THEG, SPATA20, KRI1, CNTN2, KANTNB1, FBXO24, PRPPH, HEATR9, IQCN, FUZ, C9orf131, C20orf173, TMCO5A, GTSF1, ROPN1L, ADAD1, BANF2, TSSK1B, CRISP2, RIMBP3, LYZL2, CABS1). Here, INPP1 is linked to male infertility.
