Feeling tired all the time? Losing motivation? Struggling with low sex drive, erectile dysfunction, weight gain, or loss of muscle?
A lot of men brush these symptoms off as "just getting older," being stressed, working too much, or not sleeping enough. And sometimes, that may be part of the picture.
But sometimes there is more going on.
Low testosterone , also called male hypogonadism , is a real medical condition. It can affect sexual health, energy, mood, muscle mass, fertility, red blood cell levels, and bone health. The important part is this: low testosterone should be evaluated properly. It should not be ignored, and it should not be treated casually based on one lab result or an online quiz.
At Kura Health, we approach men's health the same way we approach all primary care: with the right conversation, the right labs, and a treatment plan that actually fits the patient.
What Is Hypogonadism?
Hypogonadism happens when the body does not make enough testosterone for a medical reason.
Testosterone is an important hormone in men. It helps maintain sex drive, erections, sperm production, muscle mass, bone strength, red blood cell production, mood, and overall vitality. Testosterone is made mainly in the testes, but the signal to produce it starts in the brain and pituitary gland.
That means low testosterone can happen for different reasons. Sometimes the issue is with the testicles themselves. Other times, the issue is with the hormone signals coming from the brain. It can also be related to chronic disease, obesity, diabetes, sleep apnea, certain medications, prior chemotherapy or radiation, opioid use, steroid use, or past anabolic steroid use.
Symptoms of Low Testosterone
Low testosterone does not look the same in every man. Some symptoms are obvious. Others are more subtle.
Common symptoms may include:
- Low sex drive
- Erectile dysfunction
- Fewer morning erections
- Infertility or low sperm count
- Fatigue or low energy
- Decreased motivation
- Depressed mood or irritability
- Trouble concentrating
- Loss of muscle mass or strength
- Increased body fat
- Breast tenderness or enlargement
- Hot flashes, especially when testosterone is very low
- Shrinking testicles
- Low bone density or fractures
- Unexplained anemia
Let's pause here for a second.
These symptoms are real, but they are not specific to testosterone alone. Fatigue can come from sleep apnea, thyroid disease, depression, diabetes, anemia, poor sleep, medication side effects, or chronic stress. Erectile dysfunction can be related to blood pressure, vascular disease, diabetes, smoking history, medications, anxiety, or low testosterone.
That's why guessing is not enough. A proper evaluation matters.
Should Every Man Get Screened?
No. Not every man needs routine testosterone screening.
But men with symptoms should be evaluated. Men with certain risk factors may also benefit from testing, especially if they are noticing changes in sexual function, energy, strength, mood, or body composition.
You should consider scheduling a men's health visit if you have:
- Low libido or erectile dysfunction
- Fatigue that is not improving
- Loss of muscle or strength
- Weight gain, especially increased abdominal fat
- Depression, irritability, or low motivation
- Infertility concerns
- History of testicular injury, chemotherapy, or radiation
- Type 2 diabetes, obesity, or sleep apnea
- Chronic opioid or steroid use
- Unexplained anemia or low bone density
The Endocrine Society recommends diagnosing hypogonadism only when men have symptoms or signs of testosterone deficiency along with consistently low testosterone levels. They also recommend against routine screening of the general male population.
How Low Testosterone Is Diagnosed
This is where a lot of misinformation starts.
Low testosterone is not diagnosed from one random blood test.
Testosterone levels change throughout the day. They are usually highest in the morning and lower later in the day. Levels can also be temporarily affected by illness, poor sleep, overtraining, poor nutrition, and some medications.
A proper evaluation usually starts with an early morning testosterone level , often between 7 AM and 10 AM. If the level is low, it should be repeated on a different morning to confirm the diagnosis. Many guidelines use a total testosterone level below about 300 ng/dL as a common cutoff, but the number has to be interpreted with symptoms, timing, and the full clinical picture.
At Kura Health, testing may include:
- Total testosterone
- Free testosterone, when appropriate
- SHBG, when appropriate
- LH and FSH to help determine where the problem is coming from
- Prolactin, if pituitary causes are suspected
- CBC to check red blood cell levels
- PSA testing when age-appropriate
- A1c, cholesterol, thyroid testing, liver/kidney testing, or other labs depending on symptoms and history
The goal is not just to find a low number. The goal is to understand why the number is low and whether treatment is safe and appropriate.
Treatment Is Not Always Testosterone
This is important.
Not every man with low testosterone needs testosterone replacement therapy.
Sometimes testosterone improves when we treat the underlying issue. Obesity, poor sleep, untreated sleep apnea, uncontrolled diabetes, heavy alcohol use, medication side effects, chronic stress, and lack of resistance training can all affect testosterone levels.
Treatment may include:
- Improving sleep
- Screening for and treating sleep apnea
- Weight loss when appropriate
- Strength training
- Improving diabetes or metabolic health
- Reducing alcohol intake
- Reviewing medications that may lower testosterone
- Treating thyroid disease, depression, or other medical conditions
- Addressing opioid, steroid, or anabolic steroid history
For some men, these steps can make a meaningful difference. For others, testosterone therapy may be appropriate.
The key is choosing the right treatment for the right patient.
When Testosterone Therapy May Be Considered
Testosterone replacement therapy may be considered when a man has:
- Symptoms consistent with testosterone deficiency
- Repeated low morning testosterone levels
- A medical evaluation looking for the cause
- No major contraindications
- A clear discussion of risks, benefits, fertility goals, and monitoring
The goal is not to push testosterone levels as high as possible. The goal is to restore testosterone into a safe, appropriate range and improve symptoms that are actually related to testosterone deficiency.
Testosterone Treatment Options
There are several forms of testosterone therapy. The best option depends on symptoms, cost, insurance coverage, convenience, side effects, fertility goals, and patient preference.
Injections
Testosterone injections are commonly used and may be given weekly, every other week, or on another schedule depending on the medication and patient response. They can be effective and affordable, but levels may rise and fall between doses, which can cause some men to feel fluctuations in mood, energy, or symptoms.
Gels or Creams
Topical testosterone is applied to the skin. It can provide steadier levels for some patients. The major caution is transfer risk. Testosterone gel can transfer to a partner, child, or anyone who has skin contact with the application site if it is not used carefully.
Patches
Patches are applied to the skin daily. They can be convenient but may cause skin irritation.
Pellets
Pellets are placed under the skin during an office procedure and last for several months. They require less frequent dosing but are harder to adjust quickly.
Oral, Nasal, or Buccal Options
These are available in certain situations, but they are not the most common first choice for every patient. Some require more frequent dosing or closer attention to side effects and cost.
The FDA lists several approved testosterone formulations, including oral, topical gel, patch, buccal system, and injections.
Fertility: A Major Point Men Need to Know
If you are planning to have children, tell your healthcare provider before starting testosterone.
Testosterone therapy can lower sperm production. In some men, it can significantly reduce fertility. This surprises a lot of patients because testosterone is often marketed as a "men's health" treatment, but it can actually work against fertility goals.
Men who want future fertility may need a different approach and may benefit from urology or endocrinology involvement.
This is one of the most important reasons not to start testosterone from an online clinic without a full medical discussion. The Endocrine Society recommends against starting testosterone therapy in men who are planning fertility in the near term.
Who Should Be Careful With Testosterone?
Testosterone therapy can be helpful for the right patient, but it is not risk-free.
Testosterone may not be appropriate, or may require specialist evaluation, if you have:
- Prostate cancer or suspected prostate cancer
- Breast cancer
- Elevated PSA without evaluation
- A prostate nodule or significant prostate concern
- High hematocrit or high red blood cell count
- Untreated severe obstructive sleep apnea
- Severe urinary symptoms
- Uncontrolled heart failure
- Heart attack or stroke within the last 6 months
- History of blood clots or thrombophilia
- Current plans for fertility
These are not things to guess about. They need to be reviewed before starting treatment.
What About Heart Risk?
This has been a major concern for years.
The more recent data is more reassuring than some older headlines suggested, but that does not mean testosterone should be used casually.
The TRAVERSE trial studied men ages 45 to 80 with symptoms of hypogonadism, two low fasting testosterone levels, and either existing cardiovascular disease or increased cardiovascular risk. Testosterone therapy was not worse than placebo for major adverse cardiac events. In that study, the primary outcome occurred in 7.0% of the testosterone group and 7.3% of the placebo group. However, atrial fibrillation, acute kidney injury, and pulmonary embolism were seen more often in the testosterone group.
The FDA also updated testosterone labeling in 2025. The agency removed language from the boxed warning related to increased risk of adverse cardiovascular outcomes, but it added warnings about increased blood pressure with testosterone products.
So where does that leave us?
Testosterone therapy may be reasonable for men with true hypogonadism who are properly evaluated and monitored. But it should not be treated like a supplement, a shortcut, or an anti-aging product.
Monitoring Matters
If you start testosterone therapy, follow-up is not optional.
Monitoring usually includes:
- Symptom improvement
- Testosterone levels
- CBC and hematocrit
- PSA when appropriate
- Blood pressure
- Acne, swelling, mood changes, breast tenderness, sleep apnea symptoms, and urinary symptoms
- Review of dosing, timing, and side effects
AAFP summarizes that men receiving testosterone therapy should be monitored for symptom improvement, adverse effects, adherence, testosterone levels, hematocrit, and PSA when appropriate.
The goal is to treat safely, not just prescribe and disappear.
What Testosterone Therapy Is Not
Testosterone is not a magic fix.
It is not a substitute for sleep. It is not a substitute for exercise. It is not a substitute for treating diabetes, obesity, sleep apnea, depression, or vascular disease. It is not approved to improve athletic performance or physical appearance. It is not something men should buy online without proper monitoring.
Testosterone therapy should be used when there is a real diagnosis, a clear indication, and a safe follow-up plan.
