vasectomies are always performed with at least a local anesthetic, while pain meds are rarely if ever used for IUD insertions. Let me say that again: these two procedures—one for men, and one for women—are both invasive and both involve very sensitive body parts. It’s expected that the procedure will be painful for men, so pain relief is always administered. For women, it’s expected that if it is painful, the women will just endure it, and pain relief is almost never administered.
