Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study investigates whether vaginal estrogen treatment has an effect on hemostatic parameters in postmenopausal women. Blood samples are collected before and after 3 months treatment to assess changes in hemostasis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This prospective cohort study includes 90 postmenopausal women aged ≥ 50, having vaginal atrophy symptoms and indication for treatment with vaginal estrogen tablets 10 µg at least 3 times a week for 3 months. Participants are divided into 2 study populations. Study population 1: 45 without a history of venous thromboembolic event and study population 2: 45 with a history of venous thromboembolic event.

Participation will involve 2 visits:

* First visit: prior the initiation of treatment an interview is carried out to assess inclusion criteria and information on demographics followed by blood sampling.
* Second visit: follow-up blood sampling after three months treatment. Hemostatic parameters will be assessed, comparing the blood samples at baseline with the follow-up blood sample.
