What is the primitive stem cell of spermatogenesis called?

The primitive stem cell of spermatogenesis is known as spermatogonia. These cells are crucial in the male reproductive system as they are the earliest precursor cells from which sperm cells develop. Spermatogonia undergo both mitosis to produce more spermatogonia and meiosis to eventually form spermatids, which later mature into spermatozoa.

Spermatogonia are located in the seminiferous tubules of the testes and serve as the foundation for the entire process of sperm production, making them fundamental for male fertility. As differentiating cells, they progress through various stages before becoming mature sperm, emphasizing their role as the starting point in spermatogenesis.

In contrast, spermatids and spermatozoa represent later stages in the development of sperm cells. Oogonia, on the other hand, are the female equivalent stem cells involved in oogenesis, which is the process of egg cell development. This distinction underscores the importance of spermatogonia specifically as the primitive stem cells in spermatogenesis.
