Assisted reproductive technologies

1. Couples who have failed to respond to traditional in fertility treatments, including those with tubal disease, severe endometriosis, oligospermia, immunologic or unexplained infertility, may benefit from in vitro fertilization (IVF), gamete intrafallopian transfer (GIFT) and zygote intrafallopian transfer (ZIFT)

a. All of the procedures involve ovarian stimulation to produce multiple oocytes

2. GIFT - involves the placement of sperm and eggs in the uterine tube by laparoscopy or minilaparotomy and is more invasive than IVF

3. GIFT is not appropriate for women with severe tubal disease and is less successful than IVF ZIFT - fertilization occurs in vitro, and the early development of the embryo occurs in the uterine tube after transfer by laparoscopy or minilaparotomy

a. A recent development is intracytoplasmic sperm injection (ICSI) which allow fertilization with a single sperm, this provides the opportunity for men with severe oligospermia or obstructive azoospermia to father children.

b. Artificial insemination in Azoospermia - if azoospermia is present, artificial insemination by a donor usually result in pregnancy, assuming female function is normal
