Age and Treatment
In 2013, the average age of women undergoing ART treatment cycles in NZ and Australia was 36 years and men 38.3 years. Women under 30 years of age undergoing fresh non-donor treatment achieved a live birth rate of 27.2% per treatment cycle. In contrast, the rate of live births of women aged 40-44 years was only 5.9% (2).
Egg freezing may become an option for those wishing to delay parenthood, but it is expensive. In women aged 35 or younger, one egg freezing cycle may give up to a 50% chance of a child from using frozen eggs later).
It may be advisable for women over 35 years of age to seek help after 6-9 months of trying to conceive.
