2. Surgical menopause
3. Endometrial thickness (bi-laminar) > 5 mm, measured by transvaginal ultrasound
4. Evidence of endometrial polyp by transvaginal ultrasound
5. Abnormal Pap smear, including cervical intraepithelial neoplasia (CIN) or cervical cancer
6. Prior exposure to hormone therapy with estrogen alone or combined therapy with estrogen/progestin, considering the following period before pre-selection (V0):
6.1 Vaginal therapy (cream, gel, vaginal capsule) - <4 weeks
6.2. Transdermal therapy (gel, patch), nasal spray - <4 weeks
6.3. Estrogen therapy/estrogen-progestogen oral SERM (Raloxifene), Tibolone, Androgens - <8 weeks
6.4. Intra-uterine therapy (Mirena) - <8 weeks
6.5. Combined injectable therapy, progestin implant (Implanon) - <3 months
6.6. Estrogenic implant (Riselle) or progestin injection (Depo-Provera) - <6 months
7. Use of medications with known effects on vasomotor symptoms such as selective serotonin-norepinephrine reuptake inhibitor (SSRIs), clonidine, gabapentin, tibolone, methyldopa and phytoestrogens in the last 30 days

10. Abnormal genital bleeding unknown cause in the last 6 months
11. History or suspected breast cancer, ovarian cancer or estrogen-dependent neoplasia
12. Suspected mammography changes for breast cancer that require further investigation (simple cysts confirmed by breast ultrasound are be allowed)
