Embryo Freezing

Embryo freezing is also known as “cryopreservation” that involves storing embryos at a very low temperature so that they can be thawed and used later. Embryo freezing is often performed when there are more embryos than needed for a single in vitrofertilization (IVF) cycle. The extra embryos are saved and potentially used during later cycles. IVF success rates are generally lower with frozen embryos than with freshly fertilized embryos, but pregnancy rates with frozen embryos have been improving in recent years. The survival rate after thawing often depends on the quality of the embryos at the time of freezing.

Embryos can be frozen from one to five days after fertilization as long as they are of good quality. Typically, they are stored in batches of one or more depending on the number of embryos that are likely to be transferred into the woman’s uterus.

Who are the best candidates for embryo freezing?

Couples undergoing IVF and have addition embryos
Medical treatments such as cancer that involve chemotherapy
Medical adversaries such polyps, poor endometrial development & cervical scarring
