How can two men have a child?

A male couple can have a child by partnering with a woman (or a couple of women) who also wants to become a parent, through a co-parenting agreement.

The child then grows up across two households with fully involved parents on both sides, each with a role defined by mutual agreement from the start.

This solution is often chosen because it allows a biological connection to the child for one of the two fathers, without the cost or legal constraints of surrogacy.
