Summary

This study looks at why some people with conditions like Turner Syndrome or galactosemia have trouble getting pregnant, and whether freezing their ovarian tissue can help them have a child in the future. Up to 200 participants aged 2 to 35 will have a small piece of ovarian tissue removed and frozen for possible later use. The study will also analyze the tissue to learn more about fertility and early menopause.
