Contraception - Sterilisation
When you feel that your desired family size has been achieved, it is possible to consider having a permanent sterilization. The options include either a tubal ligation (BTL) or vasectomy.
Some of the considerations to bear in mind are that these options entail no desire for reversal, thus some risk of regret, and that there is a risk of failure, just like all methods of contraception.
