A large proportion of women are likely to be considering the option of freezing their eggs, as they pursue their dreams and want that the ticking of their biological clock should be halted for a time. As many as 6% women are unable to conceive by age 20-24, all the way up to 64% for women aged between 40 and 44 years.
Women lose a large proportion of their natural fertility between ages 35 and 40 which is when the quality of eggs also becomes poorer. Since it is not possible to improve the quality of eggs as they have already deteriorated with time, it is possible to arrest the deterioration by freezing them. In the event Oocyte Cryopreservation is on a lot of female minds who want to buy biological time as it were.
If Oocyte cryopreservation fertility therapy is given, it results in the maturation of multiple eggs in the female ovaries.
These eggs are then removed, dehydrated and then frozen by storage in liquid nitrogen. As and when required they can be thawed, fertilized by sperm and then transferred to the woman’s uterus when embryo(s) form.
This is however no guarantee that a woman will be able to have a baby in the future, plus there is no way to say how the long term health of a baby is impacted that is born from this process.
