Healthy Clinical Trial
Official title:
Intratesticular Hormone Levels in Healthy Young Men
The purpose of this investigational study is to find out what hormones are present in healthy male testicles using fine needle aspiration.
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). ;
