BioNews reported on March 23rd, “The nutrient-filled liquid used to grow embryos during IVF might affect the resulting male to female birth ratio, a study suggests. But this only seems to be true when the sperm is injected directly into the egg during fertility treatment (a technique known as ICSI).
“…Dr David Adamson, a reproductive endocrinologist and surgeon at the Advanced Reproductive Care Fertility Clinic in California, USA, told Medical Daily: ‘I don’t think it’s effective enough to say that it’s a good therapeutic intervention. This may well be true, but in the absence of information about the culture medium, it’s difficult to interpret.'”
