Turner Syndrome Hormone Replacement Therapy Estrogen Replacement Therapy Estrogen Treatment Long Term Side Effects

ClinConnect Summary

This clinical trial is studying the long-term effects of two different ways of taking estrogen replacement therapy (ERT) in women with Turner syndrome (TS), a condition that affects how a woman’s body develops. The trial will compare oral estrogen, which is taken as a pill, to transdermal estrogen, which is applied to the skin as a patch. The goal is to understand how each method affects hormone levels, heart health, and other important factors over a period of 14 months. The study involves 50 women with TS aged 18 to 50, who will receive one type of treatment for six months, then switch to the other type for another six months after a short break without treatment.

To be eligible for this trial, women with Turner syndrome must already be receiving estrogen treatment and be between 18 and 50 years old. Healthy women who do not have any health issues and are not taking any medications may also participate as a comparison group. Participants can expect to go through several health assessments during the study to monitor the effects of the treatments. This research could help develop better recommendations for hormone therapy in women with Turner syndrome in the future.
