HOP-2A - Intratesticular Hormone Levels
The purpose of this investigational study is to find out what hormones are present in healthy male testicles using fine needle aspiration.
|Study Design:||Observational Model: Case-Only
Time Perspective: Retrospective
|Official Title:||Intratesticular Hormone Levels in Healthy Young Men|
- Intratesticular Hormones in Normal Men [ Time Frame: 6-weeks ] [ Designated as safety issue: No ]Average between right and left testis for each subject and serum hormone concentration in 10 normal men
Biospecimen Retention: Samples Without DNA
serum blood, testicular tissue
|Study Start Date:||September 2008|
|Study Completion Date:||December 2009|
|Primary Completion Date:||January 2009 (Final data collection date for primary outcome measure)|
We will collect a very small amount of fluid from each testicle. Participation will last up to 12 weeks. The study involves a minimum of 4 visits, the screening visit and procedure Day, fine needle aspiration of the testes (about 1-1.5 hours each) and two follow-up visits (about 30-45 minutes). Over the course of the study, you will have a little less than a 1/3-cup of blood drawn (roughly 2-3 tablespoons at each visit).
