This would depend on several factors. Typically if your partner’s age is over 37-40 we start to lean a bit more towards assisted reproductive techniques such as IVF. On the other hand, if your partner is under age 37 it is much more cost-effective to undergo a vasectomy reversal. Also if you're considering having multiple children it is often much more cost-effective to do the reversal. Some couples have very tight time schedule for pregnancy. In these cases assisted techniques (like IVF) are more predictable at achieving a pregnancy.
