This option is available to women who are diagnosed with cancer or other illnesses that may affect their fertility. It is also an option for healthy women who wish to delay attempting to achieve pregnancy until later, knowing that as we age our fertility function decreases. During an egg-freezing cycle, a patient will go through many of the same steps that are involved in a typical IVF cycle: ovulation stimulation, ultrasound monitoring, and egg retrieval. After egg retrieval, the eggs will be cultured for a few hours and then frozen the same day for future use.
