Tests Included:
Follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone levels.
Sample Required:
Blood sample
Test Time:
Results are typically available within a few days.
Test Range Values:
Normal values for FSH, LH, and testosterone vary by age and sex. In adult males, typical levels are:
- FSH: 1.5 to 12.4 international units per liter (IU/L)

- Testosterone: 300 to 1,000 nanograms per deciliter (ng/dL)
What is the test?
This test measures hormone levels critical for testicular function, including FSH, LH, and testosterone. FSH and LH are essential for stimulating the testes to produce sperm and testosterone.
Test Procedure:
A blood sample is collected from a vein, and the concentrations of FSH, LH, and testosterone are measured in the laboratory.
When to take the test:
This test is recommended when assessing testicular function, fertility issues, or suspected hormonal imbalances related to the testes.
Who should take the test:
Patients experiencing symptoms like infertility, low sperm count, erectile dysfunction, or delayed puberty may need this test to assess testicular function.
Precautions for exceptional cases (pregnancy, etc.):
Testicular function testing is not applicable to pregnancy.

Q2: Can testicular function tests help diagnose infertility?
A: Yes, these tests assess hormonal levels critical for sperm production, aiding in the diagnosis of infertility issues related to testicular function.
Q3: How soon can results of the testicular function test help with treatment decisions?
A: Depending on the specific condition, results might prompt immediate treatment or further investigation to determine the cause of any abnormalities.
Q4: What are some lifestyle factors that can impact testicular function?
