A drop in sex drive is one of the most common reasons men come to a clinic — and one of the most fixable, once you know what is driving it. Low libido in men is rarely just “in your head”: it usually reflects hormones, health, medication or stress, often in combination. Here is how to find the cause and what actually restores desire.
What counts as low libido
Libido is your baseline interest in sex, and it varies naturally between men and across life. It becomes worth investigating when it drops noticeably from your own normal and stays low, especially if it comes with fatigue, mood changes or erectile difficulty. Note that low libido and erectile dysfunction are different problems — you can have desire but struggle with erections, or lose desire while erections still work — though they often travel together.
The common causes
Low testosterone
Testosterone is the main driver of male desire, and low levels are one of the most direct causes of low libido. It typically comes bundled with fatigue, low mood, poor concentration and loss of muscle. This is the first thing worth measuring.
Other hormones
High prolactin, thyroid disorders and imbalances in estrogen can all suppress libido, which is why a proper work-up looks beyond testosterone alone.
Stress, mood and sleep
Chronic stress and elevated cortisol suppress desire directly and lower testosterone. Depression and anxiety blunt libido, and so do the poor sleep and exhaustion that come with them. Relationship strain is a genuine and common factor too.
Health conditions and medications
Diabetes, obesity, cardiovascular disease and metabolic syndrome all reduce libido. So do several common medications — particularly SSRI antidepressants, some blood-pressure drugs, and finasteride for hair loss. If your desire fell after starting a new medication, that is a strong clue.
Lifestyle
Heavy alcohol use, smoking, a sedentary routine and excess body fat all pull libido down, largely through their effect on testosterone and vascular health.
How the cause is diagnosed
Because the causes overlap, the goal is to sort them out rather than guess. A useful work-up includes a morning blood test for total and free testosterone, plus prolactin, thyroid function, and metabolic markers — our blood test packages cover these — alongside a review of your mood, sleep, relationships and every medication you take.
What restores desire
- Treat low testosterone where blood tests confirm it: TRT commonly restores libido within the first few weeks, or Clomid for men prioritising fertility.
- Address mood, stress and sleep — often the single biggest lever in younger men with normal hormones.
- Review medications with your doctor if one coincides with the drop; alternatives often exist.
- Fix the lifestyle basics — weight, alcohol, activity — which lift both testosterone and desire.
When to get it checked
If low desire has lasted more than a few weeks and is affecting you or your relationship, it is worth a proper assessment rather than waiting it out. At Boost Health Clinic in Jakarta and Bali, we test hormones, screen for the medical and lifestyle drivers, and match treatment to the actual cause.
