From the Guidelines
No, oxytocin is not used to treat erectile dysfunction (ED). The standard medications for ED are phosphodiesterase type 5 (PDE5) inhibitors such as sildenafil, tadalafil, vardenafil, and avanafil, as recommended by the American College of Physicians 1. These medications work by enhancing the effects of nitric oxide, which relaxes muscles in the penis and increases blood flow, facilitating erection.
- The American College of Physicians recommends initiating therapy with a PDE-5 inhibitor in men who seek treatment for erectile dysfunction and who do not have a contraindication to PDE-5 inhibitor use, based on high-quality evidence 1.
- Oxytocin is a hormone primarily used in obstetrics to induce labor, prevent postpartum hemorrhage, and stimulate milk letdown for breastfeeding.
- While oxytocin does play a role in sexual behavior and bonding, there is insufficient clinical evidence supporting its use as an ED treatment, and the American College of Physicians does not recommend for or against routine use of hormonal blood tests or hormonal treatment in the management of patients with erectile dysfunction due to insufficient evidence 1.
- Men experiencing ED should consult with a healthcare provider who can recommend appropriate FDA-approved medications, lifestyle modifications, or other treatments such as vacuum erection devices, penile injections, or in severe cases, penile implants.
From the Research
Oxytocin and Erectile Dysfunction
- Oxytocin may have a role in the treatment of erectile dysfunction (ED), as suggested by preclinical data 2
- However, the current treatments for ED include phosphodiesterase 5 inhibitors, phentolamine, prostaglandin E1, and papaverine, with oxytocin not being a commonly used treatment 2, 3, 4
- The use of oxytocin in ED treatment is still being researched, and more studies are needed to determine its efficacy and safety in this context
Current Treatments for ED
- Phosphodiesterase 5 inhibitors are the leading drugs for the treatment of ED, and are recommended as a first-line treatment by both the European and US urological guidelines 3
- Other treatments for ED include intracavernous injection therapy, surgical treatment with multicomponent inflatable penile implants, and penile arterial revascularisation and venous ligation surgery 4
- Lifestyle modification, reduction of comorbid vascular risk factors, and treatment of organic or psychosexual dysfunction are also important aspects of ED treatment 4
Research on Oxytocin and ED
- There is limited research on the use of oxytocin in the treatment of ED, with most studies focusing on other treatments such as phosphodiesterase 5 inhibitors 2, 3, 4, 5, 6
- Further research is needed to determine the potential benefits and risks of using oxytocin in the treatment of ED, and to explore its potential as a new therapeutic strategy for this condition 2
