Dysregulation of FSH in Obesity: Functional and Statistical Analysis

• Status: Completed
• Trial end date: 2021-03-01
• Target enrollment: 0
• Participant gender: Female

Summary

Excess maternal weight, especially obesity, influences almost every aspect of fertility, from conception to problems during pregnancy. The investigators will use novel statistical methods to clarify the hormonal changes behind reproductive health conditions. A better understanding of reproductive hormonal changes in obese women may offer a way to identify new treatments.
