Here’s a new article on the underused procedure here in the U.S. Note that in Canada, vasectomies outnumber tubal ligation, a much more complicated and costly procedure. In New Zealand, half of all men have vasectomies by the age of 50. Here it is one in six. Also, here in the U.S., apparently most men are too chicken to have it done so they allow their wives to undergo a more complicated procedure that has much higher risk of actual complications. Here in the U.S. tubal ligation actually outnumbers vasectomy.
Way to go men. Leave it to your wives, even though it’s harder for them.
Of course, if you are not sure whether you may want children, both vasectomy and tubal ligation should be considered permanent. Even vasectomy is not reliably reversible. And, the reversal procedure that does exist is much more complicated than vasectomy. However, if you are sure you want no more children, I personally recommend it highly. And, do get tested to ensure you are sterile before giving up on birth control. It typically takes 20 ejaculations before all of the sperm is out of the tubes.
Lastly, vasectomy will not protect against STDs.
Feel free to ask me, if you have any questions, though I am not a doctor.
Happy spontaneous sex!
