United States Patent: 6,485,773

It seems that you can patent anything these days. Let me quote from this patent application:

"This invention regards a novel and unobvious dietary supplement formulation of relatively specific ratios of fruits, vegetables, and spices that when ingested by the male results in a significant improvement to the taste of the male ejaculate by reducing its generally salty and/or bitter taste while also adding a pleasant flavor that is considered by 98.5% of all customers as very enjoyable.
