New study aims to unravel puberty and fertility challenges in girls with rare sugar disorder
NCT ID NCT07461519
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study follows 60 girls and women with classic galactosemia, a rare genetic condition that affects how the body processes sugar. Researchers want to understand why many develop early ovarian failure and how puberty progresses. By tracking hormone levels and growth, they hope to identify factors that could help predict and manage these long-term issues.
