  • For people undergoing IVF, the nutrient-rich liquid their embryos grow in could tip the balance. The finding adds to mounting evidence that the culture medium is playing a role in an embryo's development and future health. Women undergoing IVF are treated with hormones that stimulate the release of eggs. The eggs are collected and fertilized with sperm in a dish. Sperm can either be left to do the job or, if the male partner has fertility problems, they can be injected directly into the eggs. The resulting embryos are then grown in the culture medium for between three and five days. At that point, the healthiest looking embryo is selected and implanted into the woman's uterus.
