Concept:Puberty in females is marked by the initiation of the first menstrual cycles (menarche), which requires the waking up of the dormant ovaries.
Solution:- At the onset of puberty, the hypothalamus begins secreting GnRH, which signals the anterior pituitary gland.
- The pituitary responds by primarily releasing Follicle Stimulating Hormone (FSH) into the bloodstream.
- FSH arrives at the ovaries and stimulates dormant primary follicles to begin growing, thus starting the very first ovarian cycles.
Why other options are incorrect:While LH is also released, FSH is universally recognized as the primary hormone responsible for
initiating the development of follicles at puberty. Progesterone is from the ovaries. Oxytocin is for labor/lactation.
