Scientifically known as ‘oocyte cryopreservation’ –it was solely employed for young females with childbearing prospects endangered due to ailments (generally cancer) or its therapy (chemo, radiation therapy and surgical intervention), however met with limited success. But with advancements in the freezing procedure, it has been used with greater frequency among females intending on postponing child bearing for personal pressing reasons.

The advantages are apparent. Latest data has shown that eighty percent of eggs post-freezing via vitrification have survived after defrosting and conception rates are presently approx. forty-five percent. Several private clinics have exceeds this figure. N.Y. University that employs vitrification alongside gradual chilling, furnished information in the previous year showed a fifty-seven percent conception rate, surpassing the nationwide conception rate of traditional IVF employing non-freeze eggs.

Freezing one’s eggs is hardly a laid-back affair or inexpensive technique. The procedure would commence similar to the method of harvesting eggs for in-vitro fertilization. A female would self-administer a hormone shot for stimulating egg creation. A physician would employ a needle for extracting eggs prior to them being put into liquid nitrogen storage till the time a need arises.

The costing for ovulation eliciting medicines, testing, egg removal, annual maintenance, then de-frosting, fertilizing and transfer, egg-freezing could turn out to be around ten thousand dollars for every cycle.
