However, IVF pregnancy rates are generally not affected by these conditions. Therefore, IVF is probably a better option in women with significant endometriosis or pelvic scar tissue. By age 43-44, very few women will be able to have a baby using either approach. This issue makes careful and honest counseling very important for women between about 35 to 43 years of age. I would discourage women 43 and older from pursuing either option because of the dismal success rates at that age and beyond.
Egg donation is a more viable option in that scenario.
Some women have a decline in their egg quality earlier in life than expected. The biggest advantage of tubal reversal surgery over IVF is that once the women has gone through the surgery she hopefully will not need any intervention through a physician such as drugs, medications or procedures in order to get pregnancy. Obviously, the idea is that good old fashion sex will then give them the baby that they want. There is also very low risk for multiple pregnancy - twins occur naturally in only 1 in 90 pregnancies. In vitro fertilization involves stimulating the woman with medications, taking a number of eggs from her ovaries, fertilizing them with her husbands sperm and transferring some of the resulting embryos back into her uterus with the hope that one will implant.
