  • Values are the averages ± SEM of the nuclear volumes of each cell type per testis (in mm3 per testis). SC, sertoli cell; GC, germ cell; Spg, spermatogonia; Spc, spermatocytes; Rspd, round spermatids; Espd, elongate spermatids.

  • *SPARKI cell counts are significantly different (P < 0.05; Student's t test) from wild type.
