Blood test for early or late puberty
Part of Hormones & metabolism clinical trials.
This study checks if a blood marker called INSL3 can help doctors tell when puberty is starting early or late. It may help diagnose conditions like central precocious puberty or delayed puberty more accurately.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be under 16 years old at the time of joining the study.
- If you are a boy, you must have signs of early puberty (testicles larger than 4 mL before age 9) or signs of delayed puberty (testicles smaller than 4 mL at age 14).
- If you are a girl, you must have signs of early puberty (breast development starting before age 8) or signs of delayed puberty (no breast development by age 13).
- Your parents or guardians must give written permission for you to take part, and you must agree as well.
- You cannot have other conditions that affect puberty, like certain hormone disorders or a history of treatments that could harm your reproductive organs.
- You cannot be taking any hormone medications that affect puberty or the tests used in this study.

Other trials that look related to this one.
This study looks at a simpler blood test to diagnose early puberty in children. It checks if a single blood test can replace the longer, more complex stimulation test.
This study looks at children with central precocious puberty (early puberty that starts in the brain) to see how often it's linked with other developmental issues. It compares how these children develop and respond to treatment.
This study observes children who show signs of puberty earlier than usual. It aims to better understand early and advanced puberty by tracking children's development.
This study looks at families to understand inherited (genetic or family-related) reasons some people have delayed puberty or develop puberty abnormally. It may help doctors better figure out the cause of low sex hormone levels and related hormone problems.
This study looks for new genetic causes of certain “development disorders” that involve hormone problems and how the body develops at puberty. It may help families understand the root cause, which can guide future care and testing.
This study follows families from an earlier infant feeding study to better understand what affects when puberty starts. It looks at growth and hormone-related health information to explain differences in pubertal development.
