Infertility affects up to one in eight couples worldwide. As a result, the use of in vitro fertilization (IVF) has increased over the past forty years and can help people dealing with infertility, single parents, and same-sex couples. This video does not address the serious problems with an unregulated, for-profit systems, including risks to egg donors, risks of implanting multiple embryos, and chronic illness/disability rates among IVF offspring.

“To increase the odds of success, which are as high as 40% for a woman younger than 35, doctors sometimes transfer multiple embryos at once, which is why IVF results in twins and triplets more often than natural pregnancies. However, most clinics seek to minimize the chances of multiple pregnancies, as they are riskier for mothers and babies.”
