Egyptian Pharaohs had a ritual involving masturbation into the Nile, known as the Fertility Festival, to ensure its flow.

The claim that Egyptian Pharaohs were required to masturbate into the River Nile to stabilize its flow may stem from a broader understanding of ancient Egyptian fertility rituals linked to the Nile, considered a life-source. However, no professional fact-checks or authoritative historical sources corroborate this specific claim. The references found discuss the spiritual and ritual importance of the Nile and other celebrations, but not this particular practice. Similarly, the term 'Fertility Festival' is associated with ancient celebrations tied to the Nile's significance, yet lacks direct evidence related to this claim. \nOverall, no direct evidence supports these claims, and they seem to be a mix of speculative interpretations and misunderstood ancient practices.
