Fertility preservation for other reasons. Vitrification
Over the last years It has been observed a delay in maternity for different reasons, either social, economical or because of work demands. Consequently, there is a larger difficulty in reaching pregnancy as the woman gets older due to the significant decreasing of the number and quality of the oocytes. Women younger than 38 years old with a normal ovarian reserve may postpone maternity thanks to occyte cryopreservation because it allows storing the oocytes for a future use, when the woman wants to become pregnant.
