Premenopause

Premenopause is the period leading up to menopause; in NaProTECHNOLOGY practice, it applies to any woman age 40 or older. This is an explicitly practical, age-based working definition rather than a marker of any specific physiologic threshold.⁷⁸ Its utility is clinical: it prompts RRM clinicians to consider the menopausal transition in evaluation and cycle interpretation for women in this age range.

The premenopausal years involve gradual hormonal shifts, changes in cycle length and mucus pattern, and declining fertility. CrMS charting captures these changes over time, providing data that guides clinical decisions.⁷⁸ This term is distinct from Perimenopause, which describes the physiologic transition itself rather than an age boundary.
