Perimenopausal Hormonal Fluctuations

Meaning

Perimenopausal hormonal fluctuations refer to the irregular and often significant changes in circulating hormone levels, primarily estradiol and progesterone, that characterize the transitional period leading up to menopause. This physiological phase marks the gradual decline of ovarian function, impacting the intricate balance of the female endocrine system as reproductive capacity diminishes.
