Loss of Libido in Men: Private Libido Blood Test
No energy. No interest. And no idea why?
If your sex drive has disappeared, you’re not alone — and you’re not imagining it. At Marylebone Diagnostic Centre, we specialise in private libido blood tests in London to help men uncover the real, hormonal reasons behind low desire — and start taking control again.
Why Am I Losing My Libido?
Loss of sex drive can happen for many reasons — but often, hormones are to blame. A quick private libido blood test can reveal imbalances such as:
- Low testosterone – the main hormone driving male libido
- High prolactin – which suppresses desire and performance
- Oestradiol imbalance – yes, men need a little estrogen too
- Thyroid dysfunction – slows metabolism and desire
- Elevated cortisol – chronic stress kills sexual interest
What’s Included in the Private Libido Blood Test?
| Marker | What It Tells You |
|---|---|
| Total & Free Testosterone | Libido, energy, and male confidence |
| Oestradiol | Mood and hormonal balance |
| Prolactin | Suppresses sex drive when elevated |
| LH & FSH | Brain signals controlling testosterone |
| TSH & T4 | Thyroid health and energy levels |
| Cortisol (optional) | Stress hormone that affects libido |
All tests are done discreetly, in-house, with no GP referral required.
Could It Be Hormonal?
You may need a private libido blood test if you’re noticing:
- Loss of interest in sex — even with physical stimulation
- Less frequent or absent morning erections
- Feeling mentally flat or emotionally disengaged
- Chronic fatigue or poor sleep
- Belly fat gain or reduced strength
These symptoms are classic signs of hormone imbalance — and easily testable.
