Condition
Low testosterone
Written by the Verra clinical team · Medical review pending · Last updated Oct 4, 2026
Quick answer
Low testosterone (hypogonadism) is when the body makes less testosterone than normal, confirmed by blood tests and symptoms together. It can cause low libido, fatigue and reduced muscle. Treatment options include testosterone therapy or medications like enclomiphene that support the body's own production, chosen after lab testing.
Key takeaways
- Diagnosis needs both symptoms and repeated morning blood tests.
- Testosterone therapy can lower fertility; enclomiphene may preserve it.
- Ongoing lab monitoring is part of safe treatment.
Overview
Testosterone naturally declines slowly with age. Low T is diagnosed when levels are low and symptoms are present.
Symptoms
Low sex drive, erection problems, fatigue, low mood, reduced muscle and increased body fat.
Causes
Aging, obesity, type 2 diabetes, testicular or pituitary problems, some medications and opioid use.
How it is diagnosed
Morning blood tests for total testosterone, usually repeated, plus related hormones such as LH and FSH.
When to see a doctor in person
Get in-person care for a testicular lump, breast enlargement with pain, or severe headaches with vision changes.

Questions
What is low testosterone, and how is it diagnosed?
Low testosterone, also called hypogonadism, means the body is not making enough testosterone. In adult men, diagnosis usually requires symptoms plus low levels on two separate morning blood tests. A single low result is not enough. A licensed physician reviews your symptoms, test results, and possible causes together.
What symptoms can low testosterone cause?
Low testosterone can cause low sex drive, fewer morning erections, fatigue, and reduced muscle. Results vary, and these symptoms do not prove that testosterone is low. Sleep problems, depression, thyroid disease, and medication effects can cause similar changes. Symptoms and blood tests must be reviewed together before choosing treatment.
What causes low testosterone?
Low testosterone can come from problems in the testicles or in the brain signals that control hormone production. Other factors include certain medicines, obesity, major illness, and prior cancer treatment. Testosterone also tends to decline with age, but age alone does not establish a diagnosis or a need for treatment.
What treatment options are available for low testosterone?
Low testosterone treatment depends on the cause, symptoms, blood tests, and fertility goals. Options may include treating an underlying condition, testosterone therapy, or medicines that stimulate hormone production in selected patients. A licensed physician in your state decides what is appropriate. Benefits and risks differ by treatment. Results vary.
How does enclomiphene work for low testosterone?
Enclomiphene acts on estrogen feedback signals in the brain, which may increase the hormones that tell the testicles to make testosterone. Results vary. It is not FDA-approved and is not appropriate for every cause of low testosterone. A physician must review your labs, health history, and fertility goals first.
How can low testosterone treatment affect fertility?
Testosterone therapy can lower sperm production, sometimes to very low levels, so it is generally avoided when trying to conceive. Results vary. Tell your physician about current and future fertility plans before starting treatment. Medicines that stimulate hormone production may be considered in selected cases, but they do not guarantee fertility.
What are the risks and side effects of testosterone therapy for low testosterone?
Testosterone therapy can cause acne, fluid retention, higher blood pressure, and increased red blood cell counts. It can also reduce sperm production. Results vary. Some health conditions make treatment unsafe or require added review. Your physician should discuss your risks and arrange blood tests and follow-up before prescribing.
How soon might treatment improve low testosterone symptoms?
Some low testosterone symptoms may change within weeks, while changes in muscle or bone can take months or longer. Results vary. A higher testosterone level does not guarantee symptom relief. Follow-up should review both blood tests and how you feel, rather than focusing only on reaching a lab number.
What monitoring is needed during low testosterone treatment?
Low testosterone treatment needs regular follow-up, including symptom reviews, blood tests, and side effect checks. Testing depends on the medication and your health history. Testosterone therapy often requires monitoring testosterone levels, red blood cell counts, and blood pressure. Your physician sets the schedule and decides whether prostate testing is appropriate.
Can lifestyle changes help with low testosterone?
Healthy sleep, regular exercise, and weight management may support testosterone levels and overall health, especially when excess weight or sleep problems contribute. Results vary. Lifestyle changes do not replace testing or treatment for an underlying hormone disorder. Avoid testosterone boosters and discuss supplements with your physician before using them.
