Overview
About Hormone Testing
A male hormone test is a simple blood test used to measure the levels of key chemical messengers in your body. Hormones control everything from your sex drive and energy levels to how your body produces sperm.
When you have this test, the laboratory will look closely at several vital hormones:
Testosterone: The main male sex hormone responsible for energy, muscle strength, sex drive, and sperm production.
LH (Luteinising Hormone) and FSH (Follicle-Stimulating Hormone): Hormones released by your brain that signal your testicles to produce testosterone and make sperm.
Test Information
Understanding Your Test
A detailed guide to your diagnostic procedure — from essential preparation and the purpose of the test to safety considerations and what to expect during the process.
This evaluation is a routine blood test performed by a healthcare professional (a phlebotomist, nurse, or doctor).
You will sit comfortably in a chair, and a soft, elastic band (tourniquet) will be wrapped around your upper arm to make the veins easier to see. The nurse will gently clean a small patch of skin on the inside of your elbow and insert a fine needle into a vein to collect a small sample of blood into a sterile tube. The needle is only in place for a few seconds. Once the sample is collected, the needle is removed, a small piece of gauze is applied, and you will be given a small plaster to wear for a few hours.
The test is incredibly quick and involves minimal discomfort. You will feel a small, sharp scratch as the needle enters the vein, which lasts for just a second or two.
Some men feel a mild, brief ache while the blood is being collected, but this passes immediately. If you are nervous about needles or have a history of feeling faint during blood tests, please let the clinical staff know beforehand. They are highly supportive and will gladly have you lie down safely on a clinical couch for the procedure.
Your specialist will usually recommend a hormone test if you are experiencing symptoms that suggest an underlying hormonal imbalance. It is an important first-line check if you are experiencing long-term fertility issues, a noticeable loss of early morning erections, erectile dysfunction, or a persistently low sex drive.
It is also highly recommended if you are experiencing unexplained chronic fatigue, loss of muscle mass, or mood changes, as these can all point toward low testosterone levels.
At a glance
Preparation required
- Time of day matters: To ensure absolute accuracy, you must have your blood sample taken first thing in the morning—routinely between 7am and 11am.
- Fasting requirement: You should ideally fast (have nothing to eat or drink except water) from midnight the evening before your test, as eating can temporarily lower your testosterone readings.
- Tell your doctor about any current medications, supplements, or recent viral illnesses, as these can impact your hormone balance.
Risks or considerations
- There are no serious physical risks associated with a standard blood test.
- You may notice a tiny, harmless bruise or slight tenderness around the injection site for a day or two after the test.
- The need for a repeat test: Hormone levels naturally fluctuate from day to day due to stress or a poor night's sleep.
What it can help diagnose
- Testosterone deficiency (also known as hypogonadism)
- Pituitary gland issues (the gland in the brain that controls hormone release)
- Male factor fertility problems or low sperm production

Testosterone levels follow a strict daily cycle, peaking early in the morning and hitting their lowest point in the evening. Taking the sample after 11am can lead to an artificially low reading, which might lead to an incorrect diagnosis.

If two separate morning tests confirm a deficiency, your urologist will discuss tailored treatment options with you. This may include straightforward lifestyle adjustments or the possibility of testosterone replacement therapy.
