Question

What is the primary function of Type A spermatogonia cells?

Options

• Undergo meiotic division immediately

• Stop dividing and move towards the lumen

• Absorb nutrients and increase in size

• Continue dividing to maintain a self-renewing reserve pool

Answer 1

Type A spermatogonia cells continue dividing during the multiplication phase, maintaining a self-renewing reserve pool of stem cells. This ensures a continuous supply of spermatogonia throughout life. In contrast, Type B spermatogonia stop dividing, move towards the lumen, and enter the growth phase to become primary spermatocytes.
