What is the number of primary follicles in the ovary at puberty?

Step-by-step solution

The process of formation of a mature female gamete is called oogenesis which is markedly different from spermatogenesis.

These cells start division and enter into prophase-I of the meiotic division and get temporarily arrested at that stage, called primary oocytes. Each primary oocyte then gets surrounded by a layer
