Semen is mostly water, but it also contains sperm (just 1–5%) and nutrients like protein, zinc, and sugars. While it’s generally safe to ingest and digested like food, a rare condition called human seminal plasma hypersensitivity (HSP) can trigger allergic reactions, such as swelling, itching, or difficulty breathing.

Despite myths, semen isn’t a major protein source—you’d need large amounts to see any dietary benefit. It may contain 5–25 calories per teaspoon, though research is limited.

Taste and smell can vary. Semen might be salty, sweet, or bitter depending on diet, hygiene, and health. Foods like pineapple and parsley may improve the flavor, while garlic, coffee, and alcohol may worsen it.

Interestingly, semen may contain mood-boosting hormones such as oxytocin, serotonin, and melatonin, possibly aiding stress relief or sleep. A few small studies have linked semen exposure to reduced depression and even lower risk of pregnancy complications, though more research is needed.

Most importantly, unprotected oral sex can transmit STIs. Always talk with your partner about testing. Whether you spit or swallow is entirely personal—what matters is comfort and informed consent.
