Ambient temperature in relation to ovarian reserve and early outcomes following ovarian stimulation and in vitro fertilization.

Introduction: There is limited epidemiologic evidence on the associations between ambient temperature and early outcomes of in vitro fertilization (IVF). This study examined the association between ambient temperature exposures during spermatogenesis in males and folliculogenesis in females with early IVF outcomes.

Methods: This retrospective cohort study included 529 oocyte donors linked to male partners of 1154 recipient couples who underwent 1379 oocyte thaw cycles between 2008 and 2020 at an IVF clinic in Atlanta, Georgia, USA.
