I did vasectomy at age of 21

Honestly I don't think I was there until my 30s

I think you might be missing the point of the article. I didn’t use a specific number because people are all different and develop differently. It’s generally around the mid to late 20s that most humans brains are fully developed.

I think you may have misunderstood some of what they were getting at.

To make a bad equivalency: would you have any reservations with someone younger than 18 choosing to have a vasectomy/tubes tied? What about 16? 13?

At some point we are going to agree that making that permanent¹ life choice isn't a good idea as they just simply aren't mature enough.

What the person you're responding to is trying to get at, I think, is that many of these preferences or desires can easily change in your formative years as a young adult (18-25 for full frontal lobe development, I believe).

¹I am aware that vasectomies and tubal ligations can be reversed, but that's not something you would want to be relying on with these choices. Similar to how you don't plan to be able to have a tattoo removed a few years down the line when you decide you don't like it.

I am sterilized, child free, and had the procedure around age 30.

Think what they are trying to say is why making a serious commitment like this when you can use readily available over the counter solutions like condoms.

Which I agree with. But I don't condemn anyone here - you do you 😃

Maybe stop trying to attach a number to it, whether or not to have kids is going to be a very personal thing. Instead of "should someone have kids at 21,18,27,30" or whatever

People should be asking themselves the following questions:

1. Do you want kids?
2. Is your answer to 1 being pressured by friends, family, this Lemmy community or something else?
3. Do you feel you are mentally prepared for a child?
4. Are you financially prepared and stable to have a child? (This one can vary wildly, some people are stable with houses at 18, and some are never financially stable)
5. Are you prepared to handle your child alone if your support network disappears?

Some people are going to be able check all the boxes at 18/19 some aren't going to be able to until 21 or 30 or maybe even never.

Everyone is going to have to decide for themselves and stop the whole "you shouldn't have kids at X! but not past Y!" Nonsense.

The sole exception is if you're under 18, and that's mostly because you need to finish high school at a bare minimum without distractions otherwise question 4 is going to be a long hard road. Even then the exception has an exception, if you have a well off support network (like wealthy parents)

Like the article posted by the other commenter, you can be mature and ready and wildly varying ages, 25 is a pop culture myth

I sure don’t!

That qualifies as a permanent life decision before full frontal love development has taken place.

While technically true, the massive financial barrier (at least in the US) can make it feel that way.

A successful reversal is not guaranteed and comes with a higher risk of complications.

In light of that, when you get a vasectomy your doctor will tell you to consider it as potentially permanent.
