Abstract:
Assisted reproductive techniques (ART) are procedures in which the oocyte is handled before replacement, either as an oocyte or embryo. The current success rates and pregnancy outcomes of in-vitro fertilisation (IVF), gamete intra-fallopian transfer (GIFT), zygote intra-fallopian transfer (ZIFT), intra-cytoplasmic sperm injection (ICSI), donor oocyte and frozen embryo programmes are reviewed. Some problems associated with assisted reproductive procedures are also discussed.
