Male sexual stimulants: how to choose?

Male sexual stimulants: definition

Male sexual stimulants include products and devices intended to increase desire, improve erections, delay ejaculation, or support fertility. They are divided into several categories with very different mechanisms and levels of evidence:

• Prescription medications: phosphodiesterase 5 inhibitors (sildenafil, tadalafil, vardenafil)
• Delay sprays and creams: benzocaine, lidocaine
• Natural supplements: ginseng, maca, L-arginine, zinc, ginkgo biloba
• Pheromones and fragrances: purported to increase attraction
• Fertility boosters: L-carnitine, coenzyme Q10, zinc
• Physical accessories: cock rings, vacuum pumps

Erectile dysfunction affects more than 50% of men aged 40 to 70. It may be organic (vascular, neurological, hormonal) or psychological (performance anxiety, stress, depression). Identifying the cause is the first step before choosing a product.

How an erection works

An erection is a neurovascular process. Sexual stimulation triggers the release of nitric oxide (NO) in the corpora cavernosa. NO activates guanylate cyclase, which produces cyclic GMP (cGMP), leading to the relaxation of the smooth muscle cells in the corpora cavernosa. Blood flows in, fills the sinusoidal spaces, and stiffens the penis. The tunica albuginea traps the blood and maintains the erection.

Phosphodiesterase 5 (PDE-5) inhibitors work by preventing the breakdown of cGMP, thereby prolonging muscle relaxation and blood flow. L-arginine supplements work by increasing NO production.

Scientific data by product category

PDE-5 inhibitors (sildenafil, tadalafil)

PDE-5 inhibitors are the best-documented medications for erectile dysfunction. Studies show effectiveness in 60 to 80% of cases, with an improvement of 6 to 8 points on the IIEF (International Index of Erectile Function) score. They require a prescription.

Common side effects: headaches, hot flashes, nasal congestion. Contraindicated in cases of heart disease treated with nitrates — the combination may cause severe hypotension. Consult a doctor before use.

Delay sprays (benzocaine, lidocaine)

Delay sprays contain a mild local anesthetic that reduces sensitivity in the glans to delay ejaculation. Easy to use and inexpensive. Points to consider: numbness may reduce pleasure, and the anesthetic may be transferred to the partner during intercourse—use a condom after application. See our selection of delay products.

Ginseng

A 2021 Cochrane systematic review analyzed the available studies on ginseng and erectile dysfunction. Result: an average gain of 3.5 points on the IIEF compared with placebo—an effect considered modest and probably not clinically significant. No clear documented improvement in sexual desire. Possible side effects: insomnia and gastrointestinal disorders.

Maca

Limited studies suggest an increase in male desire after 6 to 12 weeks of supplementation, but the evidence is weak and study methods are heterogeneous. No demonstrated effect on erections.

L-arginine

Precursor to nitric oxide. Studies show a moderate improvement in erections at high doses (over 5 g per day). Risk of hypotension at high doses. Over-the-counter formulations generally contain doses lower than those studied clinically.

Pheromones

Data on the effectiveness of human pheromones as sexual stimulants are primarily anecdotal. No robust studies demonstrate their effectiveness in increasing sexual attraction in adult humans. The placebo effect and the sensory component (the pleasant scent of the perfume) probably play a role in the perceived effects. See our selection of men's fragrances and pheromones.

Fertility boosters

L-carnitine and coenzyme Q10 supplements may improve sperm count and motility in some studies. Zinc is essential for testosterone production and sperm quality. These supplements are relevant for men planning to conceive, not for improving erections or desire. See our selection of fertility boosters.

Who is it for: recommendations by profile

Persistent erectile dysfunction

Consult a doctor as a priority — erectile dysfunction can be an early sign of cardiovascular disease. A complete medical evaluation is necessary before any treatment. PDE-5 inhibitors are effective in 60 to 80% of cases under medical supervision. Natural supplements do not have a comparable level of evidence.

Premature ejaculation

Benzocaine-based delay sprays offer a quick and accessible solution. For a more lasting approach, behavioral techniques (the start-stop method, the squeeze technique), and sex therapy can address the underlying cause.

Occasional loss of desire

Often related to stress, fatigue, or relationship factors — not hormonal insufficiency. A lifestyle and dietary approach (sleep, physical activity, stress reduction) is often more effective than supplements. Maca may offer gentle support after a few weeks.

Trying to conceive

Fertility boosters based on L-carnitine, coenzyme Q10, and zinc may improve sperm quality — under medical supervision and after a semen analysis to identify which parameters need improvement.

Playful exploration

Pheromones and stimulating fragrances have a genuine sensory and psychological dimension, even though their pharmacological effectiveness is debated. They can enhance the sensory experience of intercourse without any particular risk.

Common mistakes to avoid

• Taking PDE-5 inhibitors without medical advice: they are contraindicated with many cardiovascular medications and can cause severe hypotension. Always consult a doctor beforehand.
• Combining multiple supplements without precautions: some supplements interact with anticoagulants, antihypertensives, or other medications. Do not combine them without medical advice.
• Believing in "superfood" aphrodisiacs without evidence: oysters, dark chocolate, chili peppers — their reputation as aphrodisiacs is not supported by solid clinical data. A balanced diet, sleep, and physical activity have a much better-documented impact on sexual function.
• Neglecting the psychological aspect: stress, depression, performance anxiety, and relationship quality strongly affect male sexual function. No supplement can compensate for an untreated psychological or relationship issue.
• Using a delay spray without a condom: the anesthetic may be transferred to your partner during intercourse and cause a loss of sensation. Always use a condom after applying a delay spray.
• Buying unapproved stimulants online: many products sold online as "natural stimulants" contain undeclared PDE-5 inhibitors — with the same risks as prescription medications, without medical supervision.

In brief: how to choose a male stimulant

• Persistent erectile dysfunction: consult a doctor — PDE-5 inhibitors are effective in 60–80% of cases
• Premature ejaculation: delay sprays + condom after application
• Ginseng: modest effect (+3.5 IIEF), not clinically significant according to the 2021 Cochrane review
• Pheromones: no robust evidence — genuine sensory and psychological dimension
• Fertility booster development project under medical supervision after a semen analysis
• Never buy unapproved stimulants online
