To discuss:
The prenatal development of oogonia and primary oocytes; the peak number of oogonia typically attained in the fetus; why this number is so much less at the time of birth and again by the onset of puberty; and the name for the prenatal and childhood degeneration of female germ cells.
Introduction:
The growth or development of an ovum is known as oogenesis. The reproductive part of female includes the reproductive cycle, sexual cycle, and menstrual cycle. With the development of oocytes, the menstrual cycle starts through the oogenesis process. The term oogenesis is derived from the ovary; this term is related to fertilization. Oogenesis refers to the process involved in the development of the eggs.

- Egg and sperm developmentarrow_forwardWhat contributes to female embryonic developmentarrow_forwardInternal genitalia like the vagina, uterus, and ovaries in females, and the testes, epididymis, and vas deferens in males, originate from the Mullerian and the Wolffian ducts respectively. These two ducts are both present in the same fetus during the early phase of human development, but one will prevail over the other to make the developing conceptus a female or a male. If both persist, the baby will have an intersex condition. Discuss two syndromes that are examples of disorder of sex development (intersex condition), and how they will affect the future life of the newbornarrow_forward
