ABSTRACT
In the beginning of the IVF era, tubal-factor infertility was the sole indication for the treatment. Today, other indications constitute the majority of treatments, and tubal disease may account for as little as 20%, which is the case in our center at Sahlgrenska University Hospital, while 30-40% is common in many centers. It is notable that tubal-factor infertility often is reported to yield worse results than other causes of infertility. We reported tubal-factor infertility to be an independently negative predictive factor of pregnancy and birth, as compared with all other indications,1 a finding that has been confirmed by others2 in the debate on high multiple-pregnancy rates in IVF.
