Bloomington, Ind. – March 22, 2010 – A new purification process developed by Cook Medical for culture oil used in assisted reproduction eliminates traces of contaminants below detectable limits of 0.1 parts per million. The oil is purified by a proprietary refining technique that removes hydrocarbon impurities, which can have adverse effects on fertilization and threaten the viability of the developing embryos. The culture oil viscosity, MEA and LAL parameters remain unchanged.

Mineral oil is a popular choice for protecting the culture media used for embryo culture in assisted reproduction techniques such as in vitro fertilization (IVF). A covering of oil reduces osmotic stress to the embryos caused by evaporation and helps reduce fluctuation in the pH levels of the culture media, creating a more homeostatic environment for embryo development. However, mineral oil is derived from crude oil, and recent studies have documented the toxic effects associated with hydrocarbon contaminants introduced in the refining process¹.

"With Cook's new culture-oil purification method, we are meeting the critical need for a more stable atmosphere for embryonic development. Cook is delivering a contaminant-free growth environment that helps drive successful IVF cycles," said Christina Anné, vice president of Cook's Women's Health business unit. "We are committed to the research and development of cutting-edge solutions that will help today's embryologists and fertility specialists optimize outcomes for patients and families."

Cook Medical and ART
Cook Medical is a global leader in assisted reproductive technology (ART), which has resulted in the birth of approximately half a million babies in the United States according to the American Society of Reproductive Medicine. To aid A.R.T professionals and their patients, Cook recently launched CookARTLab.com, which features the industry's first interactive video tour of an A.R.T. lab. Visitors to the site can view real-world demonstrations of ovum collection, sperm injection, embryo culture and embryo transfer, with guidance on how to optimize each step for improved pregnancy rates. The website also features a knowledge base with up-to-the-minute links to the most current published research in A.R.T.; a discussion forum that allows professionals to exchange information and experiences; and a news center that posts upcoming industry events, making the Cook site a centralized resource on breaking research and best practices for fertility and reproductive specialists.
