Mao Sugiyama, 22, who is asexual, had voluntarily undergone surgery to have them removed.
But the illustrator took his frozen penis and scrotum home from hospital and organised a grim party.
He charged guests around 160 pounds per person to eat his severed genitalia in Tokyo, Japan. They were garnished with mushrooms and parsley.
According to CalorieLab.com, guests sat down to listen to a piano recital and take part in a panel discussion, before tucking into dinner.
Sugiyama, who goes by the nickname HC, had initially considered eating his own penis – but decided to serve them up instead.
He cooked the genitalia himself as he was supervised by a chef.
In a Tweet, he offered to cook his penis for a guest for 800 pounds. However, he ultimately decided to split the “meal” between six guests.
“I am offering my male genitals (full penis, testes, scrotum) as a meal for 100,000 yen (£800). I’m Japanese,” a major newspaper quoted him as tweeting.
“The organs were surgically removed at age 22. I was tested to be free of venereal diseases. The organs were of normal function. I was not receiving female hormone treatment.
“First interested buyer will get them, or I will also consider selling to a group. Will prepare and cook as the buyer requests, at his chosen location. If you have questions, please contact me by DM or e-mail,” he wrote.
In total around 70 people attended the event in the Suginami ward of Tokyo. While five people tucked into Mao Sugiyama’s genitalia, the rest of them ate beef or crocodile.
The people who ate his genitalia were a 30-year-old couple, a 22-year-old women, a 32-year-old man and Shigenobu Matsuzawa, 29, an event planner.
“It’s a once in a lifetime chance, so I decided on the spur of the moment to do it,” he Tweeted before the event.
He posted pictures of the event on his blog, but later removed them and said his decision to take them down was due to “privacy considerations.”
Sugiyama made guests sign a waiver so he was not responsible if they became ill after eating his genitalia.
The dinner party organiser joked before the event that he would be posting his recipe online.
Guests said that the genitalia were very rubbery and tasted of very little.
Suginami Police were contacted but did not launch an investigation because they said nothing had been done which was against the law.
Sugiyama, who is an illustrator, has also had his nipples removed. As an asexual, his genitalia will not be replaced with artificial female ones.
