In a man with an AMS 700 penile prosthesis who easily achieves orgasm during masturbation with the device fully inflated but cannot orgasm during intercourse (requiring >30 minutes of oral stimulation), how can he improve orgasmic response during sexual activity?

Delayed Orgasm with Penile Prosthesis: Management Approach

You should start by modifying sexual positions and practices to increase arousal during intercourse, consider referral to a mental health professional with sexual health expertise, and evaluate for testosterone deficiency with morning testosterone testing. 1

Understanding Your Situation

Your difficulty achieving orgasm during intercourse despite easy orgasm with masturbation (when the prosthesis is inflated) represents acquired delayed ejaculation (DE), defined as requiring >30 minutes of stimulation or inability to achieve orgasm despite adequate sexual stimulation and desire to ejaculate. 1 The fact that you can achieve orgasm with the device inflated during masturbation is actually important—it indicates the prosthesis itself is not preventing orgasm, but rather the specific context of partnered intercourse is the issue.

Step-by-Step Management Algorithm

1. First-Line: Behavioral and Psychological Interventions

Modify sexual positions and practices immediately to increase physical and psychological arousal during intercourse. 1 This is low-risk and may help trigger orgasmic response. Specifically:

• Incorporate alternative sexual practices or scripts that more closely replicate what works during masturbation
• Use sexual enhancement devices during partnered activity
• Increase the repertoire of behaviors that enhance arousal
• Open communication with your partner about specific stimulation needs

Consider referral to a mental health professional with expertise in sexual health. 1 Psycho-behavioral strategies can enhance psychosexual arousal and remove psychological barriers interfering with excitement during partnered sex. This addresses the psychological component that may be creating the discrepancy between solo and partnered sexual activity.

2. Medical Evaluation

Check morning testosterone levels. 1 Ejaculatory dysfunction increases with age and declining testosterone. The guidelines specifically support testosterone testing in men with delayed orgasm and ejaculation. If testosterone is biochemically low, replacement therapy should be considered per AUA guidelines. 1

Review all medications you're currently taking. 1 Many medications contribute to delayed ejaculation—particularly antidepressants (SSRIs), antihypertensives, and others. If any culprit medications are identified, discuss replacement, dose adjustment, or staged cessation with your prescribing physician. 1

3. Pharmacotherapy Options (If Behavioral Approaches Insufficient)

Important caveat: There are NO FDA-approved medications for delayed ejaculation, and evidence is weak (case reports and non-controlled series). 1 However, if behavioral approaches fail, the following medications have physiologic rationale and may be tried on a PRN (as-needed) basis before sexual activity:

Consider these PRN options (taken 1-2 hours before sex): 1

• Pseudoephedrine 60-120 mg (120-150 minutes prior)
• Ephedrine 15-60 mg (1 hour prior)
• Oxytocin 24 IU intranasal/sublingual during sex

Or these daily options:

• Cabergoline 0.25-2 mg twice weekly
• Yohimbine 5.4 mg three times daily

You must understand these have limited evidence, potential side effects, and require individualized risk-benefit discussion with your physician. 1

Critical Considerations Specific to Penile Prosthesis

While penile prostheses have high satisfaction rates (80-90% in studies), some men report decreased orgasm intensity (15%) and changes in sensation after implantation. 2, 3 This is a known phenomenon. The prosthesis does not interfere with ejaculation, sensation, or orgasm mechanically 4, but the altered penile anatomy and sensation may require adaptation.

The fact that you achieve orgasm easily during masturbation with the device inflated is reassuring—it confirms the prosthesis hardware is functioning and not preventing orgasm. The issue is likely psychological/relational adaptation to partnered intercourse with the prosthesis, or insufficient arousal/stimulation during intercourse compared to masturbation.

What NOT to Do

Do not pursue invasive procedures (pudendal nerve release, intracavernosal injections, platelet-rich plasma, or surgical interventions) for delayed ejaculation. 1 These should only be considered in ethical board-approved clinical trials, as there is no published peer-reviewed data supporting these approaches and they carry significant risks.

Common Pitfalls to Avoid

• Don't assume the prosthesis is malfunctioning just because orgasm is difficult during intercourse—your ability to orgasm during masturbation proves the device works
• Don't delay addressing this—the longer dissatisfaction persists, the more it affects both partners (studies show partner satisfaction decreases over time) 5
• Don't skip partner involvement—this is fundamentally a couples issue requiring open communication and potentially couples counseling 1

Bottom Line

Begin with behavioral modifications and consider sex therapy referral while simultaneously checking testosterone levels and reviewing medications. This addresses the most likely causes (psychological adaptation to prosthesis during partnered sex, hormonal factors, medication effects) with the lowest risk interventions first. Only consider pharmacotherapy if these approaches fail, and do so with full understanding of the limited evidence base.
