❤️🔥 Libido & sexual function
4 mechanistic pathways · 47 options
Desire and performance are separate systems and they fail separately. Wanting to and not being able to is a vascular or hormonal problem; being able to and not wanting to is a central one — dopamine, melanocortin, prolactin or stress. Sildenafil does nothing for the second, which is why it disappoints so many people who reach for it first.
The pathways
Central desire — melanocortin & dopaminergic
Desire is generated in the brain, and the melanocortin and dopamine systems are where it lives. This pathway works on wanting rather than on blood flow, and it is the one that works in women as well as men.
Vascular & erectile function
An erection is a haemodynamic event. Nitric oxide relaxes smooth muscle, blood fills, veins compress. Erectile dysfunction is also an early warning of systemic endothelial disease — the penile arteries are narrower than the coronaries and clog first, which makes this a cardiovascular symptom worth taking seriously.
Hormonal substrate — testosterone, estrogen, prolactin, thyroid
Testosterone sets the floor under desire in both sexes. Estrogen matters for arousal and comfort in women and for libido in men, which surprises people. Prolactin and thyroid are the two most commonly missed causes, and both are a single blood test away.
Stress, sleep and the things that quietly kill desire
Libido is the first thing the body switches off when it thinks conditions are bad. Chronic stress, poor sleep, SSRIs, over-training and severe dieting all suppress it — and no amount of hormonal intervention overrides an organism that has concluded now is not the time.
Test before you choose a pathway
Every route below can be argued for on mechanism. Only bloodwork tells you which one is actually your problem — and picking the wrong pathway is the most common reason someone concludes "none of this works". Across all 4 pathways, these are the 15 markers worth having in front of you first.

Frequently asked questions
This goal is broken into 4 distinct mechanistic pathways — Central desire — melanocortin & dopaminergic; Vascular & erectile function; Hormonal substrate — testosterone, estrogen, prolactin, thyroid; Stress, sleep and the things that quietly kill desire — across 47 compounds and supplements. Each pathway is a different argument about how the body gets there, so the useful question is which one matches where you are actually stuck.
The one that matches your actual limitation, which bloodwork usually settles faster than guessing. An appetite drug does nothing for someone who already undereats, and a thyroid intervention does nothing if your thyroid is fine. Each pathway page lists the markers that tell you whether it is your problem.
No. The 4 pathways are listed in mechanistic order, not by strength of evidence, and neither are the 47 options inside them. A lot of what works in this space has never had the trial run, and sorting by trial count would bury exactly the compounds you came looking for.
