Handling Gametes and Embryos: Oocyte Collection and Embryo Culture

All efforts have been taken by the clinic to prevent the exposure of oocytes or embryos to embryo-toxic pollutants from the surrounding environment (e.g., trafc, industrial hazards) or from within the clinic (e.g.,  construction materials, ventilation system, furniture, lightning, gas cylinders, disposables, detergents, and cloths). Accumulation of toxins, especially volatile organic compounds (VOCs) [1-6], in the culture media could affect the embryos’ developmental and implantation capacities, increasing miscarriage rates and reducing a couple’s chances of a successful treatment.
