Chances of pregnancy after dropping out from infertility treatments: Evidence from a social survey in Japan.

Purpose: We examined a patient's chances of pregnancy after dropping out from infertility treatments, an issue that has been largely understudied.

Method: Drawing from a nationwide Internet survey in Japan with 1930 respondents, we used data from 199 individuals (109 women and 90 men) who had undergone an infertility treatment. We estimated linear probability models to investigate the extent to which the probability of pregnancy was affected by dropping out after controlling for a couple's attributes.
