During the late reproductive years, what is the FSH level characteristic in stage -3b?

During the late reproductive years, particularly in stage -3b of the menopause transition, FSH (follicle-stimulating hormone) levels exhibit a specific pattern. In this stage, FSH levels typically remain normal rather than elevated. This is primarily because ovarian function is still present, albeit diminished, and the feedback mechanisms involving the hypothalamus and pituitary gland continue to regulate FSH production adequately.

As women approach menopause, fluctuations in hormone levels occur, but during stage -3b, these levels do not show the significant elevation that characterizes later stages of menopause. Therefore, a normal FSH level is representative of this transitional phase. This understanding is essential for comprehending how hormonal changes occur as women progress through the menopause transition and assists practitioners in providing appropriate care during this period.
