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

In the late reproductive years, particularly during stage -3b of the menopausal transition, the characteristic FSH (follicle-stimulating hormone) levels are typically normal. This stage reflects a period when the body is exhibiting some fluctuations in hormonal levels, but FSH does not rise significantly until the later stages of menopause. The ovaries still have some functional activity, and as a result, FSH levels remain within a normal range during this phase despite the onset of perimenopausal changes.

Understanding the hormonal dynamics during the menopausal transition is crucial. In earlier stages or stages closer to menopause, FSH may start to show variability or even initial elevations due to decreasing ovarian reserve, but during stage -3b, the hormone levels can still appear to be normal as the body makes the shift. Recognizing these nuances is important for accurately assessing the menopausal status of an individual and providing appropriate care.
