Question

How many primary oocytes are present when a female infant is born?

Answer 1

Hint: An egg is a female gamete cell with haploid DNA that is released from the ovary of the female body once a month. When sperm fuses with the egg inside the female body, a zygote is generated, which develops into a new organism, but this happens rarely.
The egg is the biggest cell in the human female body, measuring roughly \[0.2\] mm in diameter, while the male gamete is the tiniest cell.

Complete answer:
The process of oogenesis begins during the embryonic stage. At the moment of birth, females have about two million primary oocytes in their ovaries. Between birth and puberty, a considerable number of primordial follicles holding primary oocytes degenerate, with just \[60,000\] to \[80,000\] primary follicles remaining in each ovary by puberty.
In a healthy adult female, there are four lakhs of follicle cells in both ovaries. However, only about \[500\] egg cells mature since the majority of follicle cells degenerate during the primary oocyte stage, a process known as follicular atresia, and such follicles are referred to as atretic follicles.
Oogenesis is the process of a female gamete being produced inside the female body. This process comprises three major steps that culminate in the formation of an ovum, a mature female gamete.
Oogenesis is the term used to describe the process of an ovum forming. It's the female gamete we're talking about. The development of the immature ovum at various stages is required.
A multiplication process in which primordial germinal cells split regularly, a growth phase in which the primary oocyte's size increases dramatically, and a maturation stage in which a primary oocyte matures are all part of oogenesis.

Additional information:
Spermatogenesis differs from oogenesis in a number of ways. Menopause is the time when a woman's menstrual cycle finishes and no additional oocyte release occurs, unlike oogenesis, which begins at puberty and has no end, whereas oogenesis begins at puberty and has no end. In addition, one spermatogonia produces four sperms during spermatogenesis, but only one ovum/egg is produced at the end of oogenesis. There are no halting steps in spermatogenesis, and the phases are shorter.

Note:
Gametogenesis is the process of gamete creation. It's a condition that affects the primary reproductive organ. Spermatogenesis is the creation of male gamete sperm in the major male reproductive organ testes. Oogenesis is the process of female gamete ovum production in the primary female reproductive organ ovary. In many ways, these processes are distinct from one another.
