In short
Libido optimisation is mostly a marketing term. Here is the honest version of what raises desire in someone whose hormones are already normal.
- Sleep, alcohol, fatigue and stress. Unglamorous and by far the largest levers.
- The relationship. The principal determinant of sexual satisfaction, above hormones in midlife.
- Removing a cause. A medication, an untreated depression, or pain.
What does not work: testosterone in men whose levels are normal, DHEA in people without adrenal insufficiency, and compounded hormone mixtures.
Treatment Overview
Why is this page sceptical?
Because the market sells hormones for a problem that is usually not hormonal, and because giving testosterone to a man whose level is normal does not improve his libido.
The same applies in women: in most studies androgen levels do not correlate with sexual function, and ovarian testosterone production stays relatively constant across natural menopause.
What actually predicts sexual satisfaction?
Physical and psychological wellbeing, and the quality of the relationship with a partner. That is the direct finding, not an interpretation.
Which means that measures taken to improve health and the relationship are likely to improve your sex life, and that lifestyle changes which reduce fatigue and stress and strengthen the partnership often have a positive effect.
The levers, in order of size
| Fatigue and stress | Under studied but major. The typical improvement in sexual interest on holiday is the clearest illustration there is |
| The relationship | Predicted sexual response across the menopause transition more than hormones did |
| Sleep | A third of adults get under seven hours, with irritability and poor motivation among the recognised consequences |
| Alcohol | A common cause of low desire in men, and consistently understated |
| Medication | SSRIs above all, plus antipsychotics, benzodiazepines, opioids and prostate drugs |
| Untreated pain or illness | Any serious condition reduces desire, and treating it improves it |
What about relationship duration?
Sexual activity and satisfaction decline as a relationship lengthens, which is a documented pattern rather than a personal failing.
Desire over time declined only in women in one large study, while desire for tenderness declined in men and rose in women. Knowing that changes how a mismatch is read.
Does desire have to come first?
No, and this is one of the most useful things on this page. For many people in long term relationships, desire is not present before sexual activity but appears with arousal in response to pleasurable activity.
People are also often motivated by other reasons, including emotional closeness. Satisfaction does not require reaching every phase of the response cycle.
Where hormones do belong
- Men with confirmed low testosterone, where replacement improves desire reliably
- Either sex with raised prolactin or thyroid disease
- Women with painful sex from genitourinary syndrome of menopause, treated with local oestrogen
- Women starting systemic oestrogen with sexual concerns, where transdermal is preferred over oral because oral lowers free testosterone
Who Is a Good Candidate?
- Your hormones have been checked and are normal, but desire has still dropped
- You are being offered hormone treatment and want to know whether it applies to you
- Sleep, alcohol or workload have all drifted in the same direction
- You want an honest account of what is realistically achievable
- You are already taking supplements or hormones for this and want them reviewed
- You want testosterone regardless of your levels, which is not something that will be prescribed
- Pain with sex, which is a specific and treatable problem rather than a desire problem
- Persistent low mood or loss of interest in everything, which needs assessment before anything else
What Happens During the Consultation
-
1
What has actually changed
Desire in general, or desire with a particular partner, or in a particular situation. Situational patterns point strongly to relationship or psychological factors rather than to anything hormonal.
-
2
An audit of what you are already taking
Supplements, hormones and protocols, placed into three groups: keep, stop, or no evidence either way and your choice. Compounded hormones and saliva testing are not continued.
-
3
The measurable inputs
Sleep hours and the weekday to weekend gap, alcohol as a countable question, medication, mood, pain and workload. These are the largest levers and the ones most often skipped.
-
4
Hormones only where indicated
Testosterone, prolactin, thyroid function and oestradiol in men with low desire. In women, hormone levels are rarely the basis for a decision because they correlate poorly with function.
Program Structure & Follow-Up
What a realistic plan looks like
Two or three specific changes with numbers, not a programme. The evidence favours consistency over ambition here as much as anywhere.
The first six weeks
- One change at a time, usually sleep or alcohol, since both are countable
- Any medication implicated is reviewed with the condition it treats kept in mind
- A pain problem, if there is one, is treated first, because treating pain often improves interest and arousal at the same time
Where counselling comes in
Not as a last resort. Sex therapy and couples counselling are effective and safe, and a consultation with a sex therapist is generally considered a prerequisite before trying drug treatment for sexual dysfunction.
Sex therapy includes education about the sexual response cycle, negotiating a mutually acceptable frequency where interest differs, and specific exercises such as sensate focus.
What if the mismatch is the problem?
If you are content with your own level of interest and the distress comes from a difference with a partner, that is a relationship issue rather than your sexual dysfunction, and couples counselling manages it effectively.
Being told that plainly is often more useful than anything else in the appointment.
Benefits, Limits & Safety
What is realistically achievable
A meaningful improvement, usually over months rather than weeks, from a small number of changes that are unglamorous and free.
What is not achievable is the level of desire from a different decade of your life or a different relationship, and setting that expectation honestly at the start is part of the treatment.
What is not offered
- Testosterone in men with normal levels, which does not work
- Routine testosterone in women, where the trial effect was about one additional satisfying event in four weeks and gel trials found none
- Systemic DHEA in people without adrenal insufficiency, which does not appear to improve sexual function
- Compounded hormone mixtures, which ranged from 67.5 to 268 per cent of labelled potency when tested
- Saliva hormone testing to guide doses
- Supplements marketed for libido, which are rarely tested in randomised trials at all
The most useful reframe
Improvement in one area often improves another. Treating pain improves interest and arousal. Treating a mood disorder improves desire. Improving sleep improves nearly everything.
That is why the plan works on the largest lever first rather than on desire directly.
Expectations, stated honestly
Most sexual issues do not have an easy or immediate treatment, and there is usually a period of trial and error before function improves. Saying so at the start is more useful than promising otherwise.
The real levers
Sleep, alcohol, fatigue, the relationship, and removing a medication or pain that is causing it. Unglamorous and much larger than any hormone effect at normal levels.
One change at a time
Countable changes with a review at six weeks, and pain treated first because that alone often improves interest and arousal.
Not prescribed
Testosterone at normal levels, routine testosterone in women, systemic DHEA without adrenal insufficiency, compounded hormones and saliva testing.
Cost & Program Investment
The consultation is quoted individually and any tests are quoted before they are ordered. For many people this appointment reduces spending rather than adding to it, because supplements and hormone protocols without evidence are identified and stopped. Where referral to a sex therapist or couples counsellor is the right step, that is arranged and its cost explained before you commit.
Frequently Asked Questions
Yes, but not with hormones. The largest levers are sleep, alcohol, fatigue, the relationship, and removing a medication or a pain problem that is causing it.
Not if your level is normal. In men it improves desire reliably only where deficiency is confirmed. In women, levels do not correlate with sexual function in most studies.
They are rarely tested in randomised trials at all, because nothing requires them to be. Correcting a genuine deficiency helps. Beyond that the confident claims are not backed by the same evidence as medicines.
Not necessarily. For many people in long term relationships desire appears with arousal rather than before it, and satisfaction does not require reaching every phase of the response cycle.
It is a documented pattern. Sexual activity and satisfaction decline with relationship duration, and in one study desire declined over time in women while desire for tenderness declined in men and rose in women.
If you are content with your own level and the distress comes from the difference, that is a relationship issue rather than a sexual dysfunction, and couples counselling manages it effectively.
Longer than most marketing suggests. Most sexual concerns have no quick fix and there is usually a period of trial and error. Sleep and alcohol changes show fastest, often within weeks.
