OBJECTIVE: To evaluate the efficacy of ultra-low-dose 10-microgram 17beta-estradiol (E2) vaginal tablets for treatment of vaginal atrophy. METHODS: Postmenopausal women (N=309) were randomly assigned to 10-microgram E2 or placebo vaginal tablets for 52 weeks in a multicenter, double-blind study. Primary efficacy endpoints included change from baseline to week 12 in vaginal cytology, vaginal pH, and most bothersome urogenital symptoms score. Grading of vaginal health was a secondary efficacy assessment. Safety assessments included endometrial biopsy, physical and gynecologic examinations, and recording adverse events. RESULTS: At week 12, the change from baseline for 10 micrograms E2 compared with placebo demonstrated significant improvement in vaginal Maturation Index (proportion of parabasal cells: -37% compared with -9%; superficial cells: 13% compared with 4%; intermediate cells: 24% compared with 5%; P<.001 for each), Maturation Value (25.0 compared with 6.5, P<.001), grading of vaginal health (-0.91 compared with -0.51, P<.001), vaginal pH grade (-1.3 compared with -0.4, P<.001), and most bothersome symptoms score (-1.23 compared with -0.87, P=.003). For each component of vaginal Maturation Index, vaginal Maturation Value, grading of vaginal health, and vaginal pH, treatment effects were statistically different from placebo after 2 weeks of treatment. For most bothersome symptoms, treatment effect became apparent after 4 weeks and reached statistical significance at week 8 of therapy. All treatment effects were statistically significant at week 52. There were no major safety findings regarding physical, gynecologic, or laboratory assessments. CONCLUSION: After 12 weeks of treatment, an ultra-low-dose 10-microgram E2 vaginal tablet, compared with placebo, demonstrated significant improvement for the primary endpoints: vaginal cytology and pH and most bothersome urogenital symptoms score.

OBJECTIVE: To evaluate the efficacy of two vaginal doses of estradiol (E2) compared with placebo in the treatment of atrophic vaginitis. METHODS: In a multi-center, randomized, double-blind, parallel-group study, 230 postmenopausal women received treatment with 25 mcg or 10 mcg E2 or placebo for 12 weeks. Efficacy was measured through composite score of three vaginal symptoms and grading of vaginal health. Additional analyses included maturation of vaginal and urethral mucosa. Safety assessments included endometrial biopsy, adverse events, changes in laboratory tests, and physical examinations. After 12 weeks of treatment, all patients were switched to the open-label extension and received treatment with 25 mcg E2 up to week 52. RESULTS: Vaginal tablets with 25 mcg and 10 mcg E2 showed significant (P<.001) improvement in composite score of vaginal health. Other results with 10 mcg E2 were not entirely consistent with those for 25 mcg E2. Over 12 weeks, both active treatments resulted in greater decreases in vaginal pH than placebo. There were no significant differences between the 25 mcg and 10 mcg E2 groups in terms of improvements in maturation value or composite score of three vaginal symptoms. The efficacy was maintained to week 52 with 25 mcg E2. CONCLUSION: Vaginal tablets with 25 mcg and 10 mcg E2 provided relief of vaginal symptoms, improved urogenital atrophy, decreased vaginal pH, and increased maturation of the vaginal and urethral epithelium. Those improvements were greater with 25 mcg than with 10 mcg E2. Both doses were effective in the treatment of atrophic vaginitis.

The Endocrine Society Clinical Guidelines on Androgen Therapy in Women (henceforth referred to as the Guidelines) do not necessarily represent the opinion held by the many health-care professionals and clinicians who are specialized in the evaluation, diagnosis, and treatment of women's health in androgen insufficiency states. The recommendations provided in the published Guidelines are neither accurate nor complete. We disagree with the therapeutic nihilism promoted by these Guidelines. The members of the Guidelines Panel (henceforth referred to as the Panel), in their own disclaimer, stated that the Guidelines do not establish a standard of care. Based on data available in the contemporary literature, on the role of androgens in women's health, we provide in this commentary a point-by-point discussion of the arguments made by the Panel in arriving at their recommendations. It is our view that the Guidelines are not based on the preponderance of scientific evidence. Health-care professionals, physicians, and scientists often disagree when determining how best to address and manage new and emerging clinical issues. This is where we stand now as we endeavor to understand the role of androgens in a woman's health and welfare. Indeed, some basic facts are not in contention. All agree that dehydroepiandrosterone sulfate (DHEA-S) production from the adrenal gland begins during the preteen years, peaks in the mid 20s, then declines progressively over time. In contrast, ovarian androgen (i.e., testosterone) secretion commences at puberty, is sustained during a woman's peak reproductive years and declines as a woman ages, with a more rapid and steep decrease after surgical menopause. However, there are ample data to suggest that adrenal androgens play a role in the development of axillary and pubic hair, and that testosterone is critical for women's libido and sexual function. We take this opportunity to invite members of the Panel on Androgen Therapy in Women to discuss, clarify, comment, or rebut any of the points made in this Commentary. It is our goal to elevate this debate in order to provide women who are afflicted with androgen insufficiency and sexual disorders with the highest quality health care and to relieve their distress and suffering, as well as to improve their quality of life.

Vasomotor symptoms are the most common menopausal symptom experienced by women and the leading reason menopausal women seek health care advice. The recent shift towards a more conservative use of hormone therapy (HT) during menopause has prompted the need for treatment regimens to be individualized according to symptom severity. Our objective was to develop a new algorithm that enables practitioners to customize treatment regimens according to symptom severity. In order to develop a comprehensive treatment algorithm, we conducted a literature review and considered the findings from recently published treatment guidelines from around the world. We also evaluated the results of systematic reviews investigating the efficacy and safety of complementary and alternative medicines. We found a growing trend away from prescription HT in women with mild to moderate symptoms and an increasing trend toward lifestyle modification and the use of complementary and alternative medicines. On the basis of these findings, we have developed an algorithm that accounts for symptom severity. The algorithm presented here provides treatment options based on symptom severity and a comprehensive approach for integrating lifestyle modifications and complementary therapies with prescription treatment regimens
