Egg production in females occurs during embryonic development, while sperm production occurs post-puberty in males. The process of sperm production in males is commonly referred to as
What is the difference between spermatogonia and primary spermatocytes? Each spermatogonia is diploid containing 46 chromosomes. Some spermatogonia undergo changes as they grow and increase in size by accumulating and assimilating the nourishing materials and are called primary spermatocytes which periodically undergo meiosis and others that are left behind are termed as spermatogonia. Albeit anatomical and histological differences are obvious between cystic and epithelial arrangements of spermatogenesis, the basic organizational features of germ cells is similar. In all species male germ cell differentiation is initiated with a differentiating mitotic division of duplets or small chains (2-16 cells) of undifferentiated A Read about when spermatogenesis occurs and what spermatogonia are. Updated: 11/21/2023 Table of Contents. Primary Spermatocytes What is the difference between primary and secondary spermatocytes? 1. Introduction. Spermatogenesis is an essential physiological process for living organisms, in terms of the inheritance of the genome. This long and dynamic differentiation process in the seminiferous tubules takes about 60-70 days in humans and about 30 days in mice, which results in the transformation of spermatogonial stem cells (SSCs) through spermatogonia, primary spermatocytes

Gametogenesis may differ between males and females. Male gametes are called sperm. Female gametes are called eggs. In human males, for example, the process that produces mature sperm cells is called spermatogenesis. During this process, sperm cells grow a tail and gain the ability to "swim," like the human sperm cell shown in Figure below.
