Postpartum Vaginal Estrogen
Study Details
Study Description
Brief Summary
Sexual dysfunction is very common in the postpartum period and is more common in people who breastfeed or pump. This research study was designed to help determine whether postpartum patients who use vaginal estrogen cream while breastfeeding have improved sexual function compared to postpartum patients who do not.

Detailed Description
This will be a prospective, randomized clinical trial of postpartum breastfeeding patients. Postpartum patients at University Hospitals (UH) MacDonald Women's Hospital will be evaluated for inclusion/exclusion by review of their medical record by the study investigators prior to discharge home. The study will then be discussed with the eligible patients privately. If they agree to participate, informed consent will be obtained. At this time, contact information will be obtained for all consenting patients.
Between 5 and 6 weeks postpartum, all consented patients will be contacted via their preferred form of communication. Inclusion criteria and desire for continued study participation will be verified prior to randomization. A baseline REDCap questionnaire will be texted or emailed to confirmed study participants. UH REDCap is a HIPAA-certified, secure, web-based data storage platform for research studies.
The patient will then be randomized in a 1:1 ratio into two study groups: vaginal estrogen or vaginal moisturizer. Randomization will be performed using blocking with a block size of 10 and a 1:1 allocation ratio. The randomization sequence will be generated using a random number table.
After randomization, but not prior to 6 weeks postpartum, the investigational drug service courier service will deliver softgel inserts of vaginal estrogen to the homes of participants randomized to the estrogen arm. Study investigators will deliver vaginal moisturizer to the homes of participants randomized to the placebo arm. Study participants will be provided with an instructional handout including information about how and how often to use the inserts or the moisturizer. Participants will be instructed to start using the inserts or lubricant when they receive the delivery. This will be considered the start of the study period.
During the study period, participants will use either estrogen or vaginal moisturizer nightly for two weeks and then twice weekly for ten weeks. Each week during the study period, participants will receive a message via their preferred communication method with four questions:
-
Did you breastfeed or pump this week?
-
Were you sexually active this week?
-
If you were sexually active, did you have vaginal pain with sexual activity?
-
How many times this week did you use the vaginal insert?
12 weeks into the study period, the patient will be contacted by their preferred communication method and requested to complete a questionnaire via UH REDCap.
The initial study questionnaire will include questions about demographics, gravidity and parity, prior deliveries (including mode of delivery, obstetric lacerations, and infant feeding), baseline sexual activity, prior pelvic surgery, chronic pain disorders, and plans for infant feeding. The 12-week study questionnaire will include the FSFI, the GAD-7 anxiety questionnaire, the Edinburgh Postnatal Depression Scale (EPDS), and the urinary distress inventory (UDI-6) as well as questions about sexual activity and plans for infant feeding.
Questionnaire responses will be reviewed by a study investigator after completion by the patient. Any patients whose questionnaires indicate possible depression (EPDS score 10+), thoughts of self-harm (any answer other than "never" on EPDS question 10), or moderate to severe anxiety (GAD-7 score 10+) will be evaluated for safety by a physician study investigator and referred to UH Reproductive Behavioral Health.
In order to assess long term benefits of estrogen therapy in the early postpartum period, additional questionnaires will be administered at 6 months and 1 year to patients. The study intervention period will last 12 weeks, after which no additional vaginal estrogen or vaginal moisturizer will be administered to participants. Patients desiring to continue treatment after the 12-week study intervention period will be referred to their postpartum care provider. Patients will be instructed to stop estrogen use after they have completed breastfeeding.
