The consent form also states as to what will happen to the frozen embryos in case of sudden death of the both partners. There are certain distinct advantages which Embryo freezing offers which are stated below:
• It enhances the chances of conception in case multiple IVF cycles fail.
• Ethical issues related to embryo disposal are eliminated as embryos stored in freezing conditions can be retrieved for later use.
