Abstract

Purpose

The purpose of this research was to study whether methotrexate (MTX) as treatment for ectopic pregnancy (EP) impacts the future fertility of women undergoing assisted reproductive technology (ART)

Methods

In a systematic review and multi-center retrospective cohort from four academic and private fertility centers, 214 women underwent an ART cycle before and after receiving MTX as treatment for an EP. Measures of ovarian reserve and responsiveness and rates of clinical pregnancy (CP) and live birth (LB) were compared in the ART cycles prior and subsequent to MTX.

Results

Seven studies were identified in the systematic review, and primary data from four institutions was included in the final analysis. Women were significantly older in post-MTX cycles (35.3 vs 34.7 years). There were no differences in follicle stimulating hormone, antral follicle count, duration of stimulation, oocytes retrieved, or fertilization rate between pre- and post-MTX cycles. However, post-MTX cycles received a significantly higher total dose of gonadotropins (4206 vs 3961 IU). Overall, 42 % of women achieved a CP and 35 % achieved a LB in the post-MTX ART cycle, which is similar to national statistics. Although no factors were identified that were predictive of LB in young women, the number of oocytes retrieved in the previous ART cycle and current AFC were predictive of LB (AUC 0.76, 0.75) for the older women.

Conclusions

MTX does not influence ovarian reserve, response to gonadotropin stimulation, and CP or LB rate after ART. MTX remains a safe and effective treatment option for women with asymptomatic EPs.
