Perimenopause and Career: The Biological Cost of Compensation

The article redefines perimenopause not as a linear decline in estrogen, but as a phase of dynamic instability and chaos of the hypothalamus-pituitary-ovarian axis. The author explains that ovarian aging leads to unpredictable hormonal fluctuations, which complicates diagnostics based on single blood tests. The introduction of the STRAW+10 standard allows for precise staging of the process based on menstrual cycle dynamics. The text emphasizes that the cascade of symptoms—from brain fog to thermoregulation disorders—often coincides with the peak of women's professional activity. This biological transformation generates a so-called cost of compensation, where women must exert more effort to maintain their previous level of performance in the face of increasing symptomatic burden and neurobiological destabilization.
