The proportion of women after the age of 35 undergoing IVF is constantly on the rise. Oocytes retrieved from older women are often of lower quality then oocytes retrieved from younger women. It is believed that due to the lower quality the fertilization rate is decreased in this population. However a recently published retrospective study including 745 women did not show an advantage for ICSI over conventional IVF. Contrary to what is believed, the conventional IVF group had a higher number of zygotes formed, more cycles with embryos transferred at the blastocyst stage and more cycles where embryos were available for cryopreservation.
