• Patients with documented normal Pap within 12 months of study entry

Exclusion Criteria:

• Use of any estrogen or progesterone depot-preparation drug or progestin implant in the last 6 months before study entry

• Use of any androgen or anabolic steroids in the last 6 months before study entry

• Use of any oral or transdermal hormonal products (estrogen, progestin, or DHEA) within the last 8 weeks prior to study entry; however, a subject can elect to wait for an 8-week washout period before study entry.

• Use of any vaginal or intrauterine hormonal products in the last 8 weeks; however, a subject can elect to wait for an 8-week washout before study entry.

• Use of any natural over the counter estrogenic products in the last 6 months; however, a subject can elect to wait for a 6-month washout before study entry.

• Prior radiation to the pelvis or history of gynecologic cancer

• Inability to tolerate a vaginal/speculum exam

• Undiagnosed, persistent or recurring genital bleeding or other indication of active pelvic disease process that has not been evaluated [6]

• Clinically significant uncontrolled depression or severe psychiatric symptoms

• If subject has an established routine of inert vaginal lubricant use for routine or occasional relief of vulvar or vaginal symptoms prior to the study period, it may be continued during the study period along with the study drug.
