What is oogenesis?
Oogenesis is the process of female gamete (egg) formation in the ovaries.
Where does oogenesis occur?
Oogenesis occurs in the ovaries of female organisms.
What are the stages of oogenesis?
The stages of oogenesis include oogonia, primary oocytes, secondary oocytes, and ova.
What is an oogonium?
An oogonium is an immature female germ cell that divides to form primary oocytes.
What happens during the first meiotic division of oogenesis?
During the first meiotic division, a primary oocyte divides to form a secondary oocyte and a polar body.
What is the significance of the polar body?
The polar body is a small cell that is a byproduct of oogenesis, which typically does not develop into an egg.
When does oogenesis begin?
Oogenesis begins in the fetal stage of female development and is arrested at prophase I until puberty.
How many eggs are produced from one primary oocyte?
One primary oocyte will ultimately produce one functional egg and usually three polar bodies.
What hormonal changes stimulate oogenesis?
Hormones such as follicle-stimulating hormone (FSH) and luteinizing hormone (LH) stimulate oogenesis during the menstrual cycle.
What is the role of FSH in oogenesis?
FSH promotes the growth of ovarian follicles and the maturation of the primary oocyte into a secondary oocyte.
