Cryptorchid Screening (Protocol Using Histrelin or GnRH)
- A single random sample assaying Testosterone has very little value due to wide fluctuations.
- The recommended protocol to analyze testicular production of Testosterone involves a stimulation utilizing GnRH or hCG.
- If not pending litigation, measuring Testosterone only on all four samples is sufficient.
