What is the teaching on treatment for those with medical issues preventing pregnancy, such as laparoscopic surgery for endometriosis?
There’s nothing in Catholic doctrine against a surgery for coping with endometriosis. Though we’re not supposed to have procedures for the specific purpose of making ourselves infertile, like vasectomies or tubal ligations, there are times when a surgery is medically necessary and it has infertility as in unintended consequence. A hysterectomy is a good example of this; another would be radiation treatment for cancer that renders one infertile.

Adoption first....then they can see what the Lord has planned for them.
Such surgeries, which are intended to restore damaged or diseased organs to their proper function, are commendable. Note that the surgery is addressed directly to repair the malfunction organ; it is not an attempt to replace or bypass it.
Sadly, they are not always successful.
