This comprehensive review explores the pharmacology of libido and sexual performance from both pathological (e.g., ED, HSDD) and enhancement-based perspectives.
It begins with a deep dive into the neurobiological and endocrine foundations of sexual desire and arousal, followed by detailed clinical guidelines for male and female dysfunction management. Evidence-based reviews of PDE5 inhibitors, flibanserin, bremelanotide, hormonal therapies, and emerging peptides are included, alongside critical evaluations of recreational use and the nutraceutical market.
The final sections explore frontier research—including kisspeptin, dopamine agonists, regenerative medicine, gut-brain axis modulation, epigenetics, and precision neurocircuitry targeting—signaling a shift toward personalized, curative interventions rather than symptomatic treatment.
This ebook is designed to give researchers, clinicians, and advanced biohackers a clear, evidence-based framework to understand current treatments and the evolving future of sexual pharmacology.
