   • At least 6 weeks postsurgical bilateral oophorectomy.
2. ≤5% superficial cells on vaginal cytological smear
3. Vaginal pH > 5.0

6. Use of an intrauterine device within 12 weeks before screening visit 1A.
7. Use of an investigational drug within 60 days before screening visit 1A.

8. Any clinically important abnormalities on screening physical exam, assessments, ECG, or laboratory tests, such as:

   1. Unresolved cervical cytologic smear report of atypical glandular cells of undetermined significance (AGUS) or atypical squamous cells of undetermined significance (ASCUS).

      Cervical cytologic smear report of low-grade squamous intraepithelial lesion (SIL) or greater, CIN1 or greater, or any reported dysplasia; Subjects with ASCUS are eligible only if high risk human papilloma virus (HPV) result is negative.

   2. Unresolved findings suspicious for malignancy on the breast exam; incomplete mammogram result (BI-RADS 0) or unresolved findings suggestive of malignant changes or findings requiring short interval follow-up on the prestudy mammogram (subjects must have mammography result of BI-RADS 1 or 2 to enroll.) Mammogram may be performed within 9 months prior to Visit 2 (randomization) with documentation available. (The site must obtain a copy of the official report for the subject's study file, and it must be verified that the mammogram itself is available if needed for additional assessment);
   3. In subjects with intact uterus: have a screening endometrial biopsy sample that is found by both primary pathologists to have endometrial tissue insufficient for diagnosis, no endometrium identified, or no tissue identified. (With the approval of the Medical Monitor, the screening endometrial biopsy may be repeated once);

   4. In subjects with intact uterus: an endometrial biopsy report by one central pathologist at screening with one of the following:
