This observational study is looking into why individuals with certain conditions, like Turner Syndrome, galactosemia, or premature ovarian insufficiency (early menopause), might have difficulty getting pregnant. Researchers want to understand if freezing gonadal tissue (reproductive tissue like ovaries) can help preserve fertility for these individuals. The study will analyze tissue samples taken before and after freezing to learn more about the mechanisms behind egg loss. You may be eligible if you are between 2 and 35 years old and have conditions such as Turner Syndrome, galactosemia, or variations in sex characteristics. The goal is to find out if freezing gonadal tissue can help people with these conditions have their own children in the future.

Study design
