The massive blast in Beirut, Lebanon on August 4, 2020 following the explosion of a warehouse at the Beirut Port containing large quantities of ammonium nitrate was deemed the largest environmental disaster, releasing a nitrogen dioxide plume and million tons of dust and smoke into the air of the Capital. The resulting ambient particulate matter air pollution in the aftermath of Beirut region is a potential health hazard. In this retrospective cohort study we aimed to compare the laboratory reproductive outcomes (embryo quality, blastulation rates), pregnancy, implantation and biochemical pregnancy loss rates between a control population of patients who had oocyte retrievals and embryo transfers at AUBMC within 3 months prior to the Beirut port explosion and the study group of exposed patients with oocyte retrievals and embryo transfers within a month following the explosion (from August 5th to September 5th, 2020).
The study population
will consist of all women who had undergone IVF treatments and embryo transfers
(fresh and frozen) at the AUBMC Haifa Idriss Fertility Center between May 2020
until October 5, 2020 and belonging to Dr. Ghina Ghaziri and Dr. Johnny Awwad.
This is a review of IVF records (embryology and clinical data) at AUBMC
Haifa Idriss Fertility Center belonging to Dr. Ghina Ghaziri and Dr. Johnny Awwad.
