We read with interest the editorial commentary by Dr. Moragianni (1) on our recent publication, evaluating the effect of methotrexate on ovarian reserve and subsequent assisted reproductive technology (ART) treatment outcomes (2). The potential adverse effects of methotrexate, specifically when used in infertile patients after ovarian hyperstimulation for ART, remain an important issue. As Dr. Moragianni summarizes, the majority of the literature does not demonstrate an adverse effect of methotrexate. However, the data are limited by the fact that all of the current studies are retrospective. An adequately powered randomized controlled trial would be the most appropriate way to answer this question definitively. However, the low rate of ectopic pregnancy occurring after ART has made addressing this issue in a prospective manner a challenge. Our study required a 7-year time span at a busy ART program to accrue 189 patients.The DEMETER (Evaluation of Therapeutic Strategies for Treatment of Ectopic Pregnancies and Evaluation of Subsequent Fertility) trial published earlier this year serves as a good study model to address this question (3). The DEMETER trial took place in 17 centers in France over a 5-year time frame, randomizing spontaneously occurring ectopic pregnancies in fertile women to methotrexate or conservative surgery. Two hundred subjects were necessary to have a power of 80% to detect a 20% difference in subsequent cumulative fertility rates. Two years after treatment, the cumulative pregnancy rates were 67% in the methotrexate arm and 71% in the surgical arm, demonstrating no significant adverse effect of methotrexate on fertility in a spontaneously fertile population.
