Science and safety

What the research says, what it doesn't, and when to see a doctor.

The research

These studies looked at pelvic floor training, not the Stamena app. They were small, and results vary.

• Control. In a small study of 40 men, 33 regained control after 12 weeks of pelvic floor training. Pastore et al., Therapeutic Advances in Urology, 2014
• Erections. In a trial of 55 men, 40% regained normal erections and about a third improved with pelvic floor training. Dorey et al., British Journal of General Practice, 2004
• Overview. A review of pelvic floor training for men. Myers and Smith, Physiotherapy, 2019

Talk to a doctor first if you have

• Pain in your pelvis, testicles, or when urinating or ejaculating
• Had surgery on your prostate, bladder, or pelvis recently
• A urinary infection, prostatitis, or trouble passing urine
• Blood in your urine or semen

While you train

• See a doctor about erection problems, especially if they're new. They can be an early sign of heart disease or diabetes.
• Don't stop any medication because of this app.
• Stop training if you feel pain.
• Only use stopping urine mid-flow once, to find the muscles. Never train that way.
• Don't overdo it. Relaxing the muscles matters as much as squeezing them.

Stamena is a training app, not medical treatment.
