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.'
'Vasectomy cakes' like the one above are becoming abundantly visible on social media as couples celebrate living together without children
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.'
Some are even getting creative with their cakes as they hold the less traditional gatherings
Couples now invite friends over to decide what to name their cars, boats or other items that they buy with the money they save on account of not having children
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.
'I had swallowed the motherhood mandate hook, line, and sinker and I had never given myself the space and time to question whether I really, really want children.'
'Our society is all about celebrating traditional milestones,' Amy Blackstone, one of the blog's authors, told the New York Post.
'You graduate, you get married, you have a child. But that's a very narrow path and isn't indicative of many people's experiences.'
'So why not decide to celebrate your choice to not have a child?'
The procedure involves severing, then sealing off, a tube called the vas deferens, which carries sperm from the testes to the penis
Vasectomy is usually carried out under local anaesthetic, and takes about 15 minutes.
The procedure involves severing, then sealing off, a tube called the vas deferens, which carries sperm from the testes to the penis.
This prevents sperm from reaching the seminal fluid (semen), which is ejaculated from the penis during sex.
There will be no sperm in the semen, so a woman's egg can't be fertilised - and the procedure has a 99.9 per cent success rate.
During a conventional vasectomy, the skin of the scrotum is numbed with local anaesthetic.
The doctor makes two small cuts, about 1cm long, on each side of the scrotum.
The incisions allow the surgeon to access the vas deferens, or sperm-carrying tubes.
Each tube is cut and a small section removed.
The ends of the tubes are then closed, either by tying them or sealing them using diathermy (an instrument that heats to a very high temperature).
Men will not feel any pain, although it may feel slightly uncomfortable.
The incisions are stitched, usually using dissolvable stitches, which will disappear naturally within about a week.
After a vasectomy, a man's hormones remain normal, and there is no noticeable difference in his ejaculate volume, since sperm make up only a tiny part of the semen.
Because the sperm cannot come out after the vas deferens is cut, like other dead body cells, the sperm disintegrate and are reabsorbed by the body.
