Hypogonadism (Primary and Secondary)
What is Hypogonadism (Primary and Secondary)?
Hypogonadism is a condition where your body does not produce enough testosterone. Testosterone is the primary male sex hormone that supports muscle mass, bone density, energy levels, mood, and sexual function. When levels drop too low, usually below 300 ng/dL, you may experience a range of symptoms that affect your daily life and long-term health.
There are two main types of hypogonadism. Primary hypogonadism means your testicles are not producing enough testosterone even when your brain signals them correctly. Secondary hypogonadism means the problem starts in your brain, where the hypothalamus or pituitary gland fails to send proper signals to your testicles. Both types result in low testosterone, but the underlying cause differs.
Hypogonadism can develop at any age, though it becomes more common as men get older. Some men are born with conditions that lead to low testosterone. Others develop it later due to injury, illness, medications, or lifestyle factors. The good news is that blood testing can identify low testosterone levels, and treatment options can help restore hormonal balance and improve quality of life.
Symptoms
- Low sex drive and reduced sexual function
- Persistent fatigue and low energy levels
- Difficulty building or maintaining muscle mass
- Increased body fat, especially around the midsection
- Mood changes including irritability, depression, or anxiety
- Difficulty concentrating or memory problems
- Decreased bone density leading to weaker bones
- Hair loss on face and body
- Hot flashes or night sweats
- Breast tissue development in men
Some men with hypogonadism experience only a few symptoms, while others have many. Symptoms often develop gradually, making them easy to dismiss as normal aging. However, low testosterone is not an inevitable part of getting older and deserves medical attention when it impacts your wellbeing.

Causes and risk factors
Primary hypogonadism occurs when the testicles cannot produce adequate testosterone. This can result from genetic conditions like Klinefelter syndrome, undescended testicles, mumps orchitis, hemochromatosis, physical injury to the testicles, or cancer treatment including chemotherapy and radiation. Some men are born with testicular problems, while others develop them through infection or trauma.
Secondary hypogonadism happens when the pituitary gland or hypothalamus in your brain fails to signal testosterone production properly. Causes include pituitary disorders, inflammatory diseases, HIV/AIDS, obesity, type 2 diabetes, chronic stress, medications like opioids or steroids, excessive alcohol use, and normal aging. Lifestyle factors play a significant role in secondary hypogonadism. Poor sleep, lack of exercise, high stress levels, and excess body fat can all suppress testosterone production. Identifying the root cause helps determine the best treatment approach.
How it's diagnosed
Hypogonadism is diagnosed through blood testing that measures your total testosterone levels. Your doctor will typically order a morning blood draw, since testosterone levels are highest early in the day. A total testosterone level below 300 ng/dL generally indicates hypogonadism, though the diagnosis also depends on your symptoms. Most doctors will confirm low levels with a second test before starting treatment.
Rite Aid offers convenient testosterone testing at Quest Diagnostics locations nationwide. Our flagship panel includes total testosterone screening, making it easy to check your levels without multiple doctor visits. If your results show low testosterone, you can discuss next steps with a healthcare provider. Additional tests may be needed to determine whether you have primary or secondary hypogonadism and identify the underlying cause.
Treatment options
- Testosterone replacement therapy through injections, gels, patches, or pellets
- Weight loss if overweight, as excess body fat suppresses testosterone production
- Regular strength training and resistance exercise to build muscle and support hormone health
- Improved sleep quality with 7 to 9 hours per night
- Stress management through mindfulness, therapy, or relaxation techniques
- Reduced alcohol intake and elimination of opioid use when possible
- Treatment of underlying conditions like diabetes, sleep apnea, or pituitary disorders
- Nutritional changes including adequate protein, healthy fats, and zinc-rich foods
- Vitamin D supplementation if levels are low
- Regular monitoring of testosterone levels to adjust treatment as needed

Frequently asked questions
Primary hypogonadism means your testicles cannot produce enough testosterone even with proper signals from your brain. Secondary hypogonadism means the problem starts in your pituitary gland or hypothalamus, which fail to send the right signals to your testicles. Both result in low testosterone, but treatments may differ based on the underlying cause.
Most doctors diagnose hypogonadism when total testosterone falls below 300 ng/dL. Normal testosterone levels typically range from 300 to 1,000 ng/dL in adult men. However, diagnosis depends on both your blood test results and your symptoms, not just the number alone.
Yes, certain lifestyle changes can raise testosterone levels, especially in secondary hypogonadism. Losing excess weight, strength training regularly, improving sleep quality, managing stress, and reducing alcohol intake all support healthy testosterone production. However, these changes may not be enough if you have primary hypogonadism or severely low levels.
Testosterone replacement therapy is generally safe when properly monitored by a healthcare provider. Regular blood tests help ensure your levels stay in a healthy range. Potential risks include increased red blood cell count, acne, sleep apnea, and prostate changes, which is why ongoing medical supervision is important.
If you have symptoms of low testosterone, get tested to establish a baseline. Once you start treatment, your doctor will likely recheck levels every 3 to 6 months initially, then annually once stable. Men over 40 with risk factors may benefit from yearly screening even without symptoms.
Yes, hypogonadism can reduce sperm production and make it harder to conceive. Testosterone replacement therapy can further decrease fertility by suppressing sperm production. If you want to have children, talk to your doctor about fertility-preserving treatment options before starting testosterone replacement.
No, while testosterone naturally declines with age, true hypogonadism can occur at any age. Young men can develop low testosterone from genetic conditions, testicular injury, pituitary disorders, obesity, or certain medications. Age-related decline is gradual, while hypogonadism causes more significant symptoms regardless of age.
Most men notice improvements in energy levels, mood, sex drive, and sexual function within weeks to months of starting treatment. Muscle mass and strength typically increase over 3 to 6 months. Bone density improvements take longer, often 1 to 2 years of consistent treatment.
Yes, excess body fat, especially around the abdomen, converts testosterone into estrogen and suppresses production. This creates a cycle where low testosterone makes it harder to lose weight, and excess weight further lowers testosterone. Losing 10 to 15 percent of body weight can significantly improve testosterone levels in overweight men.
Many primary care doctors can diagnose and treat straightforward cases of hypogonadism. However, complex cases may benefit from an endocrinologist, a doctor who specializes in hormones. A specialist can help identify underlying causes, manage difficult cases, and coordinate care if you have multiple health conditions.
