If you’ve heard friends talking about “penis Botox,” “cocktox,” or P-Tox, you’re not imagining things—the conversation is real, and it’s growing in Chicago. At Vesper Aesthetics, we offer a modern, inclusive approach to sexual wellness and intimate aesthetics, grounded in safety, transparency, and real clinical technique. As of August 2025, we are the only formally trained clinic offering P-Tox in the Chicago area, and we designed this long-form guide to answer the questions you might not want to ask in a waiting room.
Whether you’re exploring options for erectile dysfunction, curious about combining P-Tox with Scrotox, hoping for improved sexual function, or navigating fertility/infertility concerns, this page lays out what’s known, what’s emerging, and what’s still unproven—so you can choose confidently.
“P-Tox” (colloquially “cocktox”) refers to the targeted use of botulinum toxin type A in specific penile or pelvic-floor structures by trained clinicians. The goal is to strategically relax selected smooth or skeletal muscles, modulate local nerve signaling, and improve blood-flow dynamics—often as an adjunct to other therapies for sexual function. Early clinical literature has explored intracavernosal approaches (tiny injections into erectile tissue) in men with ED who don’t respond well to first-line treatments; preliminary studies suggest add-on benefit for some patients, while larger randomized trials are still ongoing.

Important reality check: P-Tox is not a one-size-fits-all “miracle shot.” It’s a procedure that must be personalized to your anatomy, health history, medications, and goals—and it should be performed by a clinician experienced with intimate neurovascular anatomy.
In simple terms, botulinum toxin temporarily reduces muscle over-activity and modulates acetylcholine release at neuromuscular junctions. In penile applications, this can translate into:
Reduced resting tone in targeted areas, potentially easing venous outflow restriction and improving rigidity when used as an adjunct for erectile dysfunction (especially in men who respond poorly to PDE5 inhibitors alone). PubMedPMCWiley Online Library
Desensitization of overactive reflex loops or muscular contractions implicated in certain premature ejaculationphenotypes (emerging evidence—results across studies vary). PMC+1Nature+1
The exact technique (location and dosing) is determined after an in-person consult and, where appropriate, collaboration with your urologist or primary clinician. At Vesper, we prioritize safety, dosing precision, and informed consent backed by the latest evidence.
No—Scrotox is a complementary but distinct procedure that involves injecting botulinum toxin into the scrotal skin and associated muscles (e.g., dartos, sometimes cremaster) to soften wrinkles, reduce scrotal tightness, and (for some patients) improve comfort and the cosmetic drape. It’s also been explored for chronic scrotal pain and groin sweating. Evidence here includes clinical experience, case reports, and small studies; more robust comparative trials are still limited.

P-Tox targets penile/erectile function pathways. Scrotox focuses on scrotal comfort and appearance. Many clients in Chicago choose both for a comprehensive, confidence-boosting update.
Below are common goals we hear from clients across Chicago’s LGBTQ+ community and from men of all backgrounds. We’ll be candid about what is supported by early data versus what remains anecdotal or unproven.
If you’ve tried lifestyle changes, PDE5 inhibitors (like sildenafil/tadalafil), or injections—and you’re still underwhelmed—intracavernosal P-Tox as an add-on has shown promising, preliminary results in clinical studies for some men, with effects sometimes lasting several months. Randomized, larger trials are still needed, but the signal is encouraging for select patients. PubMedPMCWiley Online Library
Some patients report better sexual confidence and overall function when P-Tox is integrated into a broader plan that can include hormone optimization, pelvic-floor physical therapy, and psychosexual support. While confidence is subjective, our care model is holistic and LGBTQ+-affirming—because human sexuality is not just hydraulics; it’s identity, safety, communication, and joy.
Research is mixed. Several recent analyses and small randomized trials suggest short-term improvements in intravaginal ejaculatory latency time (IELT) after BoNT-A injections targeting specific pelvic muscles, while other reviews conclude the evidence is limited or inconsistent. If PE is your primary concern, we’ll discuss expectations, alternatives, and whether you’re a candidate for a carefully selected protocol. PMC+1Nature+1
Google searches spike for “bigger penis,” “penis enlargement,” and similar terms—so let’s be precise. P-Tox does not enlarge penile tissue. Some patients perceive fuller, better quality erections when erectile function improves, which can look bigger. But true enlargement requires other modalities. We’ll never overpromise. Your results will be anchored in realistic goals.
For clients seeking both functional and aesthetic updates, combining P-Tox with Scrotox can enhance comfort, smoothness, and in some cases reduce scrotal tightness that interferes with intimate enjoyment or certain genders expressions (e.g., a more relaxed hang in fitted clothing). Small studies and clinical experience support improved appearance and subjective comfort; robust head-to-head trials remain limited. urofrance.orgPubMed
We’re often asked about “improved fertility” or sperm quality. Human data linking penile or scrotal BoNT-A directly to improved fertility are limited. Animal studies conflict—some suggest potential testicular benefits at very low doses in specific models, while others warn of adverse effects on spermatogenesis with injections into certain muscles. Until stronger human evidence exists, we do not position P-Tox/Scrotox as a fertility treatment. We’ll gladly coordinate with your urologist/reproductive specialist to safeguard your goals. PMCPubMed
We’ll discuss your goals: erectile dysfunction, improved sexual function, performance anxiety, PE concerns, aesthetic preferences, or questions about fertility and family planning. We’ll review your medical history (cardiac status, neurologic conditions, bleeding risk, medications like anticoagulants), prior procedures, and what you’ve tried.
If you’re a candidate, we’ll design a conservative, safety-first plan. We’ll cover:
We’ll check in at 2–6 weeks, then periodically. Many clients see gradual improvements over several weeks. For some ED cases, benefits can persist for months; maintenance is individualized. PubMedPMC
Common, usually temporary effects: Mild soreness, small bruise, transient sensitivity changes.
Not in the literal enlargement sense. Some clients experience fuller, more reliable erections when ED improves, which can look and feel bigger—but P-Tox doesn’t add tissue. If you’re seeking true enlargement, we’ll discuss other pathways (and trade-offs) honestly.
“Cure” is the wrong framework. For some men—especially non-responders to first-line ED drugs—intracavernosal BoNT-A as an add-on has preliminary supportive data. We position it as a personalized tool in a broader plan, not a magic bullet. PubMedPMCWiley Online Library
Evidence is emerging and mixed. Some trials show short-term benefit; others find limited effect. We’ll determine candidacy and always set realistic expectations. PMC+1Nature+1
There’s not enough human evidence to promise improved fertility. We’ll never overstate this. If fertility is a goal, we’ll coordinate care and consider semen analysis before and after any treatment plan. PMCPubMed
Treatment-dependent. For some ED patients using P-Tox as an add-on, improvements have been reported for months; individual results vary and maintenance plans are personalized. PubMed
Often yes—smoother skin, less tightness, and a more relaxed drape. There are also reports and use cases in scrotal painand groin sweating—but large, definitive trials are limited. Healthlineurofrance.orglearnskin.com
At Vesper, you will never have to “explain” your identity or needs. We serve gay, bi, trans, non-binary, and queerclients with care that’s trauma-informed and affirming. We tailor recommendations for anatomy, hormones, medications (including PrEP), and personal goals. Whether you’re seeking improved sexual function, comfort in clothing, or confidence with partners, we meet you where you are.
If you’re trying to conceive imminently, we’ll discuss the unknowns and help coordinate with your fertility specialist to time any elective procedures responsibly. PMCPubMed
