Assisted Conception Australia and New Zealand 1999 and 2000 provides information on all pregnancies and infants resulting from the use of assisted conception techniques such as in-vitro fertilisation (IVF), intracytoplasmic sperm injection (ICSI) and gamete intrafallopian transfer (GIFT). Specifically, the report presents data on pregnancy rates, causes of infertility, maternal and paternal characteristics, number of embryos/eggs transferred, frozen embryos, donor eggs/embryos, pregnancy outcomes, multiple births and infant outcomes. The data are obtained from all IVF units in Australia and New Zealand.This report will be particularly useful to health professionals providing clinical services or otherwise working on infertility and assisted reproductive technology, couples considering assisted conception and those conducting research, or with a general interest, in assisted conception techniques and outcomes.
