Regular Ovarian Cycling Baseline
Placeholder: normal cyclic hormone rhythm before perimenopause onset.
- 28d: Cycle length (Placeholder typical value)
- Stable: Estrogen range (Placeholder baseline)
- Normal: FSH level (Placeholder baseline)
- High: Predictability (Placeholder baseline)
Baseline cycle mechanics
Placeholder: regular hormonal cycling maintained by consistent ovarian response.
Placeholder: baseline serves as the reference point for later changes.
Follicular Depletion Begins
Placeholder: declining follicle count subtly alters hormone output.
- Declining: Follicle count (Placeholder trend)
- Rising: Cycle variance (Placeholder trend)
- Occasional: Estrogen dips (Placeholder trend)
- Early: Symptom onset (Placeholder trend)
Early depletion dynamics
Placeholder: fewer responsive follicles cause subtle cycle shifts.
Placeholder: early signs are often mild and easy to miss.
Erratic Estrogen Surge-and-Drop Pattern
Placeholder: estrogen becomes volatile with sharp surges and drops.
- Frequent: Peak surges (Placeholder trend)
- Frequent: Trough drops (Placeholder trend)
- Elevated: Symptom intensity (Placeholder trend)
- Low: Cycle regularity (Placeholder trend)
Volatility mechanics
Placeholder: erratic follicle recruitment drives estrogen instability.
Placeholder: this volatility often explains fluctuating symptoms.
Rising FSH as Feedback Response
Placeholder: pituitary increases FSH to compensate for ovarian decline.
- Rising: FSH trend (Placeholder trend)
- Compensatory: Feedback loop (Placeholder trend)
- Diminished: Ovarian response (Placeholder trend)
- Diagnostic: Marker use (Placeholder trend)
Feedback loop shift
Placeholder: rising FSH reflects weakening ovarian feedback signal.
Placeholder: elevated FSH is a commonly tracked transition marker.
Trend Toward Menopause Transition
Placeholder: cycles lengthen and irregularity trends toward menopause.
- Lengthening: Cycle length (Placeholder trend)
- Widening: Hormone swings (Placeholder trend)
- Very low: Predictability (Placeholder trend)
- Approaching: Final stage (Placeholder trend)
Final transition dynamics
Placeholder: hormone patterns converge toward menopausal baseline.
Placeholder: this stage precedes the final menstrual period.
