The secondary research process involved comprehensive analysis of regulatory databases, clinical trial repositories, peer-reviewed medical journals, and authoritative women's health organizations. Key sources included the US Food & Drug Administration (FDA), European Medicines Agency (EMA), Health Canada, US Department of Health and Human Services (HHS), National Institutes of Health (NIH), National Institute on Aging (NIA), Centers for Disease Control and Prevention (CDC), World Health Organization (WHO) Global Health Observatory, National Center for Biotechnology Information (NCBI/PubMed), ClinicalTrials.gov, and the Women's Health Initiative (WHI) study database.
Professional and clinical sources included the North American Menopause Society (NAMS), American College of Obstetricians and Gynecologists (ACOG), International Menopause Society (IMS), European Menopause and Andropause Society (EMAS), American Society for Reproductive Medicine (ASRM), and The Endocrine Society. Government health statistics were obtained from the US Census Bureau, CDC National Center for Health Statistics, EU Eurostat Health Database, and national health ministry reports from key markets including the UK NHS, Germany's Federal Institute for Drugs and Medical Devices (BfArM), and Japan's Ministry of Health, Labour and Welfare.
These sources were used to collect prescription statistics, regulatory approval data for hormone replacement therapies (estrogen-only, progestin-only, combination, and tibolone) and non-hormonal treatments (NK3 receptor antagonists, SSRIs, SNRIs, gabapentinoids), clinical safety studies from WHI follow-up analyses, patient demographic trends, treatment guidelines, and the competitive landscape for menopausal symptom management including vasomotor symptoms and genitourinary syndrome of menopause.
