Various web-sites claim that consuming capsaicin (the chemical found in chili peppers which makes them hot) has an aphrodisiac effect:
Capsaicin is known to boost testosterone levels and increase libido. Chili peppers also have the ability to release endorphins, natural painkillers and your bodies response to the capsaicin.
Just like cayenne's spicy on your tongue, it helps add spice to your sex life. "Hot peppers contain capsaicin, which creates heat and improves circulation and blood flow for erections," Isadora says. The peppers have an immediate effect [...]
Healthline casts some doubts on the claim:
Hot chilies: According to popular belief, capsaicin, the compound that gives hot chilies their spiciness, stimulates nerve endings on the tongue, causing the release of sex-drive-boosting chemicals. However, no studies support this belief.
There have been experiments involving injecting capsaicin locally to trigger erections in impotent men but this question is about ingestion.
