Balancing sex hormones to improve metabolism and fertility in Klinefelter
Treatments studied
Part of Genetic & congenital, Hormones & metabolism, Kidney & urinary, Women’s health & pregnancy clinical trials.
This study tests whether adjusting sex-hormone levels can improve body metabolism and reproductive hormone balance in people with Klinefelter syndrome. Depending on the design, you may be looking at fertility preservation and/or metabolic health.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have a confirmed diagnosis of Klinefelter syndrome (47,XXY) or mosaic XXY
- Your age fits the study group you would join (16–40 or 18–65)
- For one group: you want a child or are interested in saving fertility, and you have no sperm in a semen test
- For the other group: you do not want fertility, and you have low testosterone effects (called hypogonadism) and higher metabolic risk (overweight plus insulin resistance)
- You do not have conditions that make hormone-raising treatments unsafe, like prostate or breast cancer, active liver disease, or certain heart symptoms
- You can follow the study plan and don’t have major issues with study participation (severe mental health problems, language barriers, substance abuse)

This trial tests if starting testosterone treatment during puberty (ages 10-14) helps boys with Klinefelter syndrome. It aims to understand how the hormone affects development and well-being.
This study follows patients with Klinefelter syndrome over time to learn more about their health. It may help doctors better understand and care for people with this condition.
This study looks at how the thyroid gland works and how it looks on ultrasound in people with classic (non-mosaic) 47,XXY Klinefelter syndrome. It may help doctors understand thyroid-related problems in this condition by comparing test results, symptoms, and imaging.
This study tests a new medication called leflutrozole for men with a condition where no sperm is produced (azoospermia). The drug may help increase hormone levels that support sperm production, potentially improving fertility.
This study looks at how metabolism and hormones are connected in women. It tests a treatment to see if it can improve metabolic health related to the menstrual cycle.
This study looks at how the environment affects the body's reproductive system and hormone levels. By joining, you'll help researchers understand these connections over time, which may lead to better care for people with similar conditions.
