The Health Ministry reported Tuesday that the success rate of in vitro
fertilization (IVF) treatments has dropped slightly over the past decade despite
the amount of IVF treatment cycles rising from 20,000 to 38,000 in that
The number of live births has only increased from 4,792 in 2002
to 6,901 in 2011.
The ministry said that director- general Prof. Ronni
Gamzu is contemplating a recommendation of the National Council for Obstetrics
and Gynecology to reduce the number of IVF treatments for those whose medical
situations offer no real hope for success.
At present, all women within a
specific age group are entitled to receive state-funded IVF treatment until they
give birth to two healthy babies.
While 86.4 percent of embryos created
by IVF were implanted in 2011, the rate of subsequent pregnancy was 23%, and the
rate of live births from IVG was 14.9% that year, compared to 88% implantation
rate, 25.2% pregnancy and 17.9% live births in 2002.
In other words, most
of the IVF procedures during the past decade made it possible to return embryos
to the womb; a quarter produced pregnancies; and almost a fifth ended in a live
The average number of babies delivered in each pregnancy resulting
from IVF was 1.2 in 2011, compared to 1.2 to 1.3 a decade ago. Fertility
specialists are returning fewer embryos to the womb than before to reduce the
risk of multiple pregnancies.
