30 Egg Bank (Egg Freezing)

Egg freezing is a medical procedure that involves cryogenically freezing oocytes to enhance the possibility of future
pregnancy in women who wish to have greater control over the age of marriage and giving birth.

The need for egg freezing and banking has increased as greater numbers of women enter the workforce and the age of
marriage and childbearing goes up. A woman’s fertility decreases steadily as she ages, with a drastic drop appearing after age 37, reducing greatly the ovarian function and the likelihood of pregnancy at later ages.

Egg freezing and egg banking involves the cryopreservation of good oocytes at a younger age, when postponement of
childbearing is anticipated.

This will allow for a higher success rate when attempting future pregnancies using previously frozen eggs.

Who should consider Egg Banking?
  • Women with signs or risk of premature menopause
  • Women whose marriage is delayed due to social activities, or whom wishes to preserve healthy
    eggs when they’re young to use for future childbirth
  • Cancer Patients: Risk of ovarian failure through cancer treatment
  • For unmarried women who are concerned about decreased ovarian function following unilateral or bilateral ovarian surgery.

From the onset of menstruation cycle, the female patient is stimulated by induction injections for an average of 6~9 days. Two days after the end of injections, egg retrieval is performed to retrieve the eggs from your body and freeze them.

Egg retrieval (oocyte aspiration)

The egg retrieval (egg aspiration) procedure is performed by inserting a ultrasonic device into the vagina and retrieving the egg with a thin needle while viewing the ultrasound images. It's painless as it's done under sedation anesthesia, and the procedure takes about 10 minutes.
