Test for height of testis (biometric measurement)

Why This Test Is Done

Doctors may order this test if you have symptoms like pain, swelling, or changes in testicle size, or if you’re undergoing evaluation for conditions like infertility, undescended testicles (cryptorchidism), or testicular cancer. It can also be part of a general physical exam or routine check for males of reproductive age.

How the Test Is Performed

The test involves a physical examination where a healthcare provider uses a tool called a pachymeter or by visually comparing the testicles to assess their size. No blood, urine, or other samples are taken; it’s a quick, non-invasive procedure done during a clinic visit.

What to Expect Before the Test

No special preparation is needed. Wear comfortable clothing that allows easy access to your groin area. If you have any concerns or conditions that might affect the exam (e.g., skin sensitivity), let your provider know beforehand.

What to Expect During the Test

You’ll likely be asked to lie down or stand while the provider gently measures each testicle’s length and width. The process is quick and painless, though you may feel slight pressure or discomfort if the testicles are enlarged or tender.
