Unless your DH wants more kids (or wants the potential to have more kids) I think he should go and talk through his concerns over a vasectomy with a health professional. Honestly, it is far less invasive a procedure to be done. Thankfully my DH is also 1000% done having kids and was happy to take care of birth control given that I had carried and birthed our babies, and knowing that I can't take hormonal birth control. It was condoms forever, a vasectomy, or abstinence. They were our options cause there was no way I was having more kids.
