Eggs freezing comes as a boon and most suitable option for these females who are advancing in age and their biological clocks are ticking. First pregnancy with frozen Oocytes in the world was reported in 1986 by Dr Christopher Chen from Singapore.
Chemo and Radiotherapy has toxic affects on gametes. Eggs freezing was started for cancer patients before starting chemotherapy / radiotherapy to prevent them from losing their eggs and to have their biological children later in future.
Later on this technique was preferred by the patients and treating doctors for other medical illnesses like endometriosis, history of early menopause and also for other social reasons.With the increasing awareness, trend of egg freezing is increasing in India also, the reason being medical and/or social.
