Summary

This study looks at freezing ovarian tissue in girls with Turner syndrome, a condition that often causes early ovary failure and infertility. Researchers want to find out which patients are most likely to have healthy eggs in their tissue by checking their genes, hormones, and medical history. The goal is to help preserve the chance of having biological children in the future.
