VI.2 Elements for a Public Summary
VI.2 Elements for a Public Summary VI.2.1 Overview of disease epidemiology In women in menopausal period, the decrease of hormones (estrogen levels) result in genital areas becoming dry, itchy and more easily irritated. Vaginal atrophy is a frequent complaint of these women. Symptoms associated with vulvovaginal atrophy (VVA), such as lack of lubrication and pain with intercourse, affect 20% to 45% of midlife and older women. About 50% of otherwise healthy women over 60 years of age experience symptoms related to urogenital atrophy such as vaginal dryness, dyspareunia, burning, itching, as well as urinary complaints or infections of the lower urinary tract. As these alterations frequently affect the quality of life of postmenopausal women, it is important for doctors to detect their presence and offer treatment options. VI.2.2 Summary of treatment benefits Estriol normalizes the vaginal, cervical and urethral epithelium and thus helps to restore the normal microflora and the physiological pH in the vagina. Moreover, estriol increases the resistance of the vaginal epithelial cells to infection and inflammation and decreases the incidence of urogenital complaints. Estriol, which is an estrogen, can be used in the treatment of vaginal symptoms and complaints (vaginal dryness, itching, discomfort and painful intercourse) due to estrogen deficiency related to menopause (whether naturally or surgically induced). In a randomized clinical trial versus placebo, intravaginal application of a low dose of estriol (50 micrograms per application) the main endpoint was to evaluate the efficacy of the product by evaluation of the change in the maturation value of the vaginal epithelium after 12 weeks of treatment. -

Vaginal Estriol to Overcome Side-Effects of Aromatase Inhibitors in Breast Cancer Patients

Menopausal symptoms are often aggravated during endocrine treatment. We investigated whether vaginal estriol is a safe therapeutic option to overcome the urogenital side- effects of aromatase inhibitors. Serum hormone levels were used as the surrogate parameter for safety. Methods Fasting serum hormone levels of ten postmenopausal breast cancer patients receiving aromatase inhibitors were prospectively measured by electro-chemiluminescence immunoassays and gas chromatography/ mass spectrometry before and 2 weeks after daily application of 0.5 mg vaginal estriol (Ovestin1 ovula), respectively. Results Two weeks of daily vaginal estriol treatment did not change serum estradiol or estriol levels. However, significant decreases in levels of serum follicle stimulating hormone (p ¼ 0.01) and luteinizing hormone (p ¼ 0.02) were observed. Five out of six breast cancer patients noticed an improvement in vaginal dryness and/or dyspareunia. Conclusions The significant decline in gonadotropin levels, indicating systemic effects, has to be kept in mind when offering vaginal estriol to breast cancer patients receiving an aromatase inhibitor. -

Feminizing Gender-Affirming Hormone Care the Michigan Medicine Approach
Feminizing Gender-Affirming Hormone Care The Michigan Medicine Approach Our goal is to partner with you to provide the medical care you need in affirming your gender. Our focus is on your lifelong health, safety, and individual medical and transition-related needs. The Michigan Medicine approach is based on the limited but growing medical evidence surrounding gender-affirming hormone care. Based on the available science, we believe mimicking normal physiology will provide you with the best balance of physical and emotional changes and long-term health. This philosophy aligns with current national and international medical guidelines in the care of gender diverse people. We are committed to staying up-to-date with the latest research and medical evidence to ensure you are getting the highest quality care. We know that there are competing approaches to gender-affirming care that are not based on validated scientific evidence. These approaches make scientifically unsubstantiated claims and have unknown short and long-term risks. We are happy to discuss these with you. Below are some answers to questions our patients have asked us about gender- affirming hormone care. We hope the Q&A will help you understand the medical evidence behind our approach to your gender-affirming hormone care, and how it may differ from other approaches, including the approach other well-known clinics in Southeast Michigan. Is there a benefit for monitoring both estrone (E1) and estradiol (E2) levels and aiming for a particular ratio? There are 3 naturally occurring human estrogens: estrone (E1), estradiol (E2), and estriol (E3). Your body naturally balances your estradiol and estrone ratio.
