In what is being billed as a world first, a Canadian couple has given birth to a little girl who was conceived through a two-step, test-tube method that could herald the next revolution in baby making. Researchers at the 成人VR视频 Reproductive Centre say the baby, now a healthy 10-month-old, is the first baby in the world known to be born of an egg that had not only been frozen, but that had never ripened inside of a woman. The process allowed the mother to undergo in vitro fertilization without taking standard fertility drugs.
