primary spermatocyte in meiotic metaphase I [FBbt_00057147]
Primary spermatocyte during meiotic metaphase I (GO:0007132). The chromatin is highly condensed, the parafusorial or paranuclear membranes (three to five layers of double membranes) encircle the nucleus and the astral membranes (stack of approximately 13 umbrella-shaped layers, each with a central hole) cup each pole of the spindle-shaped nucleus. The mitochondria are clustered around the equator of the spindle region and oriented parallel to the long axis of the cell.
