Yep:

Call it a sign of the times.
More couples these days want to avoid parenthood and embrace life without children.
So some are marking the start of their childless families with ‘vasectomy parties.’
One couple posted a Reddit bulletin announcing that they were inviting friends to revel in the fun of being sterilized.
The invitation calls on attendees to live it up in ‘a house filled with sharp furniture and exposed outlets,’ the Sun reported.
Instead of the traditional baby shower, couples also invite friends to ‘car showers’ where guests help them name their new car.
They also play board games like The Price Is Right, where they talk about what they can buy now that they’ve saved money by not having kids.
‘Absolutely brilliant!,’ one Reddit user replied.
‘Made me LOL, especially the wording on the invitation, the clever cake, and the advent calendar! Congratulations, by the way and have a happy childfree life!’
‘All a baby shower is a party to celebrate that you had sex,’ wrote another user. ‘That a sperm managed to hit a fertile egg. A vasectomy shower is a party to celebrate soon to be sex.’
The trend has become so pronounced that one couple posted a blog that they proudly named ‘WereNotHavingABaby.com.’
‘After six years of having looked forward to becoming a caring and all-out stimulating and dynamic mother at some indeterminate point in the near future, I suddenly realised that this wasn’t the only possible narrative for my life,’ one woman known as Stefani posted on the blog.
