Abstract:
Age is a major factor affecting the results of IVF and ET. We studied the results of 697 couples treated in our programme of in vitro fertilisation and embryotransfer. We demonstrated increasing numbers of cancelled cycles in older women--the cancellation rate was 17.7% in patients under thirty and 50% in women 38-40 years old. The cut-off line of effectivity is the age of 36-37 years. In women aged 38 and older we demonstrated a decrease of pregnancy rate per transfer from 25.5% to 14-16%. However, there was no higher pregnancy loss in older women in our series.
