Not true about development of ovary
**Core Concept**
The development of the ovary involves complex cellular and molecular processes, including the formation of the genital ridges, the migration of primordial germ cells, and the differentiation of ovarian follicles. The ovarian development is a critical aspect of reproductive biology, and any disruptions can lead to various ovarian dysfunctions.
**Why the Correct Answer is Right**
During fetal development, the genital ridges form from the intermediate mesoderm, and the primordial germ cells migrate from the yolk sac to the genital ridges. The primordial germ cells then undergo mitosis and differentiate into oogonia, which eventually form the primary oocytes. The formation of ovarian follicles is a continuous process that starts during fetal development and continues throughout childhood and adolescence. The follicular development is regulated by a complex interplay of hormones, growth factors, and genetic factors.

**Option B:** This option is not provided.
**Option C:** This option is not provided.
**Option D:** This option is not provided.
**Clinical Pearl / High-Yield Fact**
One important aspect of ovarian development is the presence of a sex-determining region (SRY) gene on the Y chromosome, which is responsible for the development of testes in males. In the absence of the SRY gene, the genital ridges develop into ovaries, and the primordial germ cells differentiate into oogonia.
**Correct Answer:** A. (Note: Please provide the actual options for a complete explanation)
