Mucuna pruriens benefits for men: what the research says
Mucuna pruriens, also called velvet bean, is a traditional Ayurvedic herb now popular in supplements for men. Here is what is known about mucuna pruriens benefits for men, and where caution is needed.
In short: Mucuna pruriens seeds contain L-dopa, a building block of dopamine. Small studies in infertile men found it improved sperm count, motility and stress markers, with some rises in testosterone. Evidence for erections is limited. Because it affects dopamine, it can interact with antidepressants and other medicines, so it should only be used with guidance.
What is mucuna pruriens?
A tropical legume whose seeds have been used in traditional medicine for fertility and vitality. The seeds naturally contain L-dopa, which the body turns into dopamine, a brain chemical involved in motivation, pleasure and sexual desire.
Possible benefits for men
Sperm quality
Several small studies in infertile men taking about 5 g of seed powder a day for three months reported better sperm count and motility. See how to increase sperm motility.
Stress and mood
Some studies showed lower cortisol and better mood markers, which may help libido.
Testosterone
Testosterone rose in some infertile men in these studies. There is little evidence in men with normal fertility.
Libido and erections
Dopamine plays a role in desire, but there are no strong trials showing mucuna improves erections.
Limits of the evidence
Most studies are small, from a few research groups, and in men with fertility problems. Results may not apply to every man.
Side effects and safety
- Nausea, bloating or headache
- Insomnia or restlessness in some men
- Possible effects on blood pressure
- Raw seeds can cause itching; products vary widely in L-dopa content
Who should avoid mucuna
- Men taking antidepressants, especially MAO inhibitors
- Men taking medicines for Parkinson’s disease or psychosis
- Men with a history of mental illness, melanoma, or heart rhythm problems
- Anyone with diabetes, as it may affect blood sugar
