Embryo freezing can help individuals achieve pregnancy later in life if they are facing difficulties, such as:
- Advancing age.
- Changes in gender.
- Issues in infertility.
- Social/personal reasons like if individuals seeking higher level education or have professional demands and plan to delay pregnancy for several decades.
- Potentially harmful treatments for fertility (for example, chemotherapy or pelvic radiation therapy for cancer).
- Women who are single may worry about aging and decide to freeze their eggs or the embryos they develop using donor sperm.
