Final answer:
Embryos can be collected, frozen, and stored for later pregnancy attempts using cryopreservation techniques, commonly used in in vitro fertilization (IVF) procedures. This method is useful when a woman has no viable eggs and allows for the use of donor eggs.
Step-by-step explanation:
Using cryopreservation techniques, people can choose to collect, freeze, and store embryos for later pregnancy attempts. In vitro fertilization (IVF) procedures produce a surplus of embryos that can be frozen and stored for future use. This method is commonly used when a woman has no viable eggs, as it allows for the use of donor eggs to achieve pregnancy.
