Metaphase may be defined as the stage of the cell cycle followed after the prophase and before the anaphase. The chromosomes are joined together with the centromere.
This stage can easily be identified in the microscope. The chromosomes are aligned themselves at metaphasal plate in the center of the cell.
Luteinizing hormone specially stimulates cells in the seminiferous tubules to particularly secrete testosterone, which has a role in sperm production and developing male secondary sex characteristics.
