Are there any supplements that can increase ejaculate volume?

Supplements for Increasing Ejaculate Volume

There are no supplements with reliable evidence to support claims of increasing ejaculate volume, and current guidelines do not recommend supplements for this purpose. 1

Current Evidence on Supplements and Ejaculate Volume

Medical Guidelines Perspective

• The American Urological Association (AUA) and American Society for Reproductive Medicine (ASRM) guidelines clearly state that "there are no clear, reliable data to support use of the variety of supplements (vitamins, antioxidants, nutritional supplement formulations)" for improving fertility outcomes 1
• No major medical guidelines specifically recommend any supplements for increasing ejaculate volume
• The focus of medical guidelines is primarily on treating conditions that affect ejaculation, such as premature ejaculation or delayed ejaculation, rather than increasing ejaculate volume 1

Research on Specific Supplements

While some animal studies have shown potential effects, human evidence is lacking:

1. Soybean Lecithin

   • Animal studies in rabbits showed increased ejaculate volume with soybean lecithin supplementation 2
   • No human clinical trials confirm this effect
   • No recommended dosage exists for humans

2. L-Carnitine

   • Studies in boars showed no effect on ejaculate volume despite improvements in other sperm parameters in specific breeds 3
   • Not recommended in human guidelines for ejaculate volume

3. Lycopene

   • One small study showed modest increase in ejaculate volume in infertile men with oligozoospermia 4
   • Limited evidence with small sample size
   • Not endorsed by medical guidelines

4. "Testosterone Boosting" Supplements

   • 90% of these supplements make unsubstantiated claims 5
   • Only 24.8% of ingredients have any data showing increased testosterone
   • Many contain potentially harmful supra-therapeutic doses of vitamins and minerals
   • Some may actually decrease testosterone levels 5

Potential Risks and Considerations

• Many supplements contain doses exceeding the Recommended Daily Allowance (RDA) and sometimes even the upper tolerable intake level (UL) 5
• Supplements are not FDA-regulated for efficacy
• A scoping review found that less than half of over-the-counter fertility supplements have been tested in clinical trials, and available studies are generally of poor quality 6
• Some supplements may interact with medications or have adverse effects

Medical Approaches for Related Concerns

If concerned about ejaculate volume as it relates to fertility:

• Medical evaluation is recommended for fertility concerns rather than self-supplementation
• Treatments should focus on underlying causes rather than symptom management
• For men with ejaculatory disorders, guidelines recommend specific medical treatments such as SSRIs or topical anesthetics for premature ejaculation 1

Bottom Line

There is insufficient scientific evidence to recommend any supplement specifically for increasing ejaculate volume. If you have concerns about ejaculate volume related to fertility or sexual function, consult with a healthcare provider for proper evaluation and evidence-based treatment options.
