Final answer:
Oocyte development is synchronized with the follicular phase of the menstrual cycle, with FSH prompting follicle maturation, leading to estrogen production, while one follicle matures fully, and others disintegrate. Oogenesis resumes at puberty with oocytes maturing and undergoing stages until ovulation.
Step-by-step explanation:
The oocyte development is closely tied to the follicular phase of the menstrual cycle. During the follicular phase, a rise in follicle-stimulating hormone (FSH) from the pituitary gland promotes the maturation of several ovarian follicles. Among these follicles, typically one develops into a mature Graafian follicle prepared to release an egg, while the others undergo atresia and disintegrate.
The maturing follicle produces estrogen, which reaches higher levels throughout this phase, coordinating with the other events of the ovarian cycle. Moreover, oogenesis, the creation of female gametes, begins with primary oocytes formed during fetal development, which resume maturation at puberty and continue this process until menopause. As folliculogenesis advances, follicles progress through primordial, primary, secondary, and tertiary stages, with the oocyte remaining primary until just prior to ovulation.
