Objectives: Investigation for seasonal variability in pregnancy and live birth rates among women undergoing Assisted Reproductive Techniques (ART).

Design: We did a retrospectives study of the pregnancy, implantation and live birth rates of the women who did ART in our centre over the past three years, 2014-2016. During that time 1451 patients had ICSI cycles. We selected 1219 patients from these for the purpose of this study. Patient selection criteria were women under 35 years of age and where ejaculated semen was used over a count of 1,000,000/ml or more. We analysed pregnancy, miscarriage and live birth rates according to the seasons patients had their cycle to accurately try to pinpoint if there was a favorable time of the year that increased pregnancy rates.

Results: There was no significance difference in pregnancy, miscarriage and live birth rates between the four seasons.

Conclusions: Seasonality does not seem to affect pregnancy and live birth rates. It should not be taken into account for patients seeking ART.
