Bone density after different estrogen treatments in young women with amenorrhea

Retrospective Observational Evaluation of the Bone Mineral Density Outcome of Different Oestrogen Therapy Regimens in Young Women With Amenorrhea

Observational IRCCS Azienda Ospedaliero-Universitaria di Bologna · NCT07015476

This project tests whether different estrogen treatment plans help improve bone density in young women (about 15–39) who have gone more than six months without periods.

What this trial studies

This is a retrospective, single-center observational analysis of patients seen at the Gynecology and Reproductive Medicine unit in Bologna between 2011 and 2020 with amenorrhea lasting over six months. Researchers compare baseline and follow-up DXA scans (lumbar spine, femur, whole body) taken at least one year apart to see how different estrogen regimens affect bone mineral density, T-scores, and Z-scores. The study also extracts clinical history, physical exam findings, pelvic ultrasound results, blood tests, and specialist reports from medical records to explore other systemic and metabolic effects of the therapies. No interventions are applied because the analysis uses existing patient records.

Who should consider this trial

Good fit: Ideal candidates are women aged about 15–39 who experienced amenorrhea for more than six months and who attended the Bologna clinic between 2011 and 2020 with documented baseline and follow-up DXA scans and recorded estrogen therapy.

Not a fit: Patients without baseline or follow-up DXA data, those who never received estrogen therapy, or those with incomplete medical records are unlikely to contribute useful information and therefore may not benefit from this analysis.

Why it matters

Potential benefit: If successful, the findings could identify estrogen regimens that better preserve or increase bone mass in young women with prolonged hypoestrogenism and help guide treatment choices to reduce long-term fracture risk.

How similar studies have performed: Previous research shows estrogen therapy can improve bone density in hypoestrogenic women, but direct comparisons of different estrogen regimens in this young population are limited, so this work builds on established effects while adding comparative detail.
