Premenopausal Hormones

Meaning

Premenopausal hormones refer to the dynamic, fluctuating levels of reproductive hormones, primarily estrogens and progestogens, experienced by individuals in the years leading to their final menstrual period. This phase, known as perimenopause, involves shifts in ovarian function, leading to irregular ovulatory cycles and variable hormonal outputs. The endocrine system transitions, reflecting declining follicular reserves and altered hypothalamic-pituitary-ovarian axis feedback.
