This study is testing if injecting special cell-made vesicles into the ovaries can help women with premature ovarian failure improve hormone levels and possibly restore their menstrual cycles.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are women aged 20-38 with a diagnosis of premature ovarian failure and elevated FSH levels.

Probably not a fit

Patients with primary amenorrhea, congenital ovarian anomalies, or significant immunological and cardiovascular diseases may not benefit from this study.

What this trial studies

This clinical trial investigates the effects of intra-ovarian injections of extracellular vesicles derived from mesenchymal stromal cells on women diagnosed with premature ovarian failure. The study aims to evaluate changes in hormone levels, specifically Follicle-Stimulating Hormone (FSH) and Anti-Mullerian Hormone (AMH), as well as the potential restoration of menstrual cycles over an 8-month follow-up period. A total of 10 eligible patients will receive the treatment, and their responses will be monitored for any side effects or complications. The trial is designed to provide insights into a novel therapeutic approach for this condition.

Why it matters

Potential benefit: If successful, this treatment could restore ovarian function and menstrual cycles in women suffering from premature ovarian failure.

How similar studies have gone: While there have been studies on the use of stem cell-derived therapies, this specific approach using MSC-derived extracellular vesicles in premature ovarian failure is novel and has not been extensively tested.
