Description

To arouse the development of numerous follicles in the ovary sequence of hormone therapy starts in all IVF treatments. Eggs from follicles are collected and then fertilized outside the body (‘in vitro’) to form embryos. Later one or two of these embryos are relocated after two to four days, into the uterus, where implantation occurs and pregnancy begins. Remaining embryos are frozen as not every embryo implants to become a pregnancy.
