long lasting male hormone

Overview

Testosterone is the main male sex hormone. It helps build muscle and bone, supports sex drive, and affects mood and energy. Low testosterone, sometimes called 'low T', happens when a man's body doesn't make enough of this hormone. It can be treated with long-lasting hormone therapy when needed.

Yes. Low testosterone is fairly common, especially in older men. Some research suggests about 2 in 100 men have it, and the number rises with age.

It mostly affects men, especially those over 40. Younger men can also have it due to certain health conditions, injuries, or treatments.

Symptoms

Common symptoms

• Low sex drive
• Erectile dysfunction (trouble getting or keeping an erection)
• Constant tiredness or low energy
• Low mood, irritability, or depression
• Loss of muscle mass and increased body fat

Symptoms in children

• Delayed or incomplete puberty
• Slow growth of facial and body hair
• Underdeveloped genitalia

Symptoms in older adults

• Weaker bones (osteoporosis) and higher fracture risk
• Reduced strength and stamina
• Poor balance or falls
• Memory or concentration problems

Causes

Main causes

• Testicular injury or infection
• Klinefelter syndrome (a genetic condition)
• Pituitary gland problems
• Certain cancer treatments like chemotherapy or radiation
• Chronic conditions such as diabetes, obesity, or kidney disease
• Long-term use of some pain medications

Risk factors

• Older age
• Obesity or metabolic syndrome
• Type 2 diabetes
• HIV or other chronic infections
• Excessive alcohol use
• Sedentary lifestyle

When to see a doctor

See a doctor urgently if:

• Sudden, severe testicle pain
• Symptoms that could suggest a heart attack or stroke

Book a routine appointment if:

• You have had low sex drive, fatigue, or low mood for more than a few weeks
• You are concerned about erectile dysfunction or muscle loss
• You have a condition that increases your risk of low testosterone

Diagnosis

Your doctor will ask about your symptoms, do a physical exam, and order a blood test for testosterone. The test is usually done in the morning, when levels are highest.

Tests that may be done

• Blood test for total testosterone
• A second testosterone blood test to confirm low levels
• Blood test for luteinizing hormone (LH) to check the pituitary gland
• Semen analysis if fertility is a concern

What to expect at your appointment

You may need to have your blood drawn twice on separate mornings. If both tests show low testosterone and you have symptoms, your doctor will discuss options with you.

Treatment

If low testosterone is confirmed and causing symptoms, treatment can help. Testosterone replacement therapy is the main approach. It comes in long-acting and shorter-acting forms. You and your doctor will decide what is best for you after discussing benefits, risks, and your preferences.

Self-care at home

• Lose weight if you are overweight
• Get regular exercise, especially strength training
• Limit alcohol
• Get enough sleep and reduce stress

Medical treatments

Testosterone replacement therapy can be given as a long-acting injection every 10 to 14 weeks, as an implant placed under the skin, or as a gel or patch used daily. While on treatment, your doctor will check your blood cell counts, prostate health, and PSA levels regularly to keep you safe.

When is surgery considered?

Surgery is not a usual treatment for low testosterone itself. However, surgery may be needed if an underlying cause is found, such as a pituitary tumor or a testicular mass.

Living with this condition

Living with low testosterone often means staying consistent with any treatment plan and keeping regular check-ups. It can take weeks or months to feel better, so patience is important.

Lifestyle tips

• Stay active with activities you enjoy
• Talk openly with your partner about how you feel
• Join a men's health support group if that helps
• Track your symptoms and share them with your doctor

Diet and exercise

A balanced diet with plenty of vegetables, whole grains, and lean protein can support your health. Exercise, especially lifting weights or resistance training, can improve energy, mood, and muscle tone.

Mental health and emotional wellbeing

Low testosterone can affect your mood, confidence, and relationships. You might feel frustrated or down. Treatment often helps, but talking with a counselor or therapist can also make a big difference.

Prevention

Not always, but you can lower your risk by keeping a healthy weight, staying physically active, managing chronic conditions like diabetes, and limiting alcohol.

Screening programmes

There is no routine screening for low testosterone in all men. Your doctor may check your levels if you have symptoms or certain risk factors.

Complications

If left untreated

• Weaker bones and a higher risk of fractures
• Loss of muscle mass and strength
• Weight gain and insulin resistance
• Persistent low mood or poorer quality of life

Long-term outlook

With proper diagnosis and follow-up, most men see meaningful improvements in energy, mood, and sexual function. Long-term treatment is safe when monitored by a healthcare professional.
