Women who choose to postpone pregnancy until their 40s are at risk for unsuccessful IVF if they freeze their eggs earlier in life.
Preemptive egg freezing is gaining popularity among women who wish to prolong their fertility. However, the technique is in its infancy and may not provide acceptable success rates.
Fertility experts suggest that embryo freezing is a more successful technique, though the woman would need a sperm donor for the procedure to take place.
Women who wait until their 40s to attempt IVF face long odds if using their own eggs. In a study of Australian women undergoing IVF, less than 1% of IVF cycles resulted in live birth for women over the age of 45.
The success rate was 25% in women between the ages of 25-34.
Experts caution that most women over the age of 40 who undergo IVF will not be able to conceive. Therefore, women should consider embryo freezing instead.
