To examine the tubes, a doctor uses X rays or a telescope-like instrument called a laparoscope, which is inserted directly into the pelvic area through a small, abdominal incision. Delicate microsurgery, and, more recently, laser surgery, sometimes can repair the damage successfully...

Medical Center in Torrance, a woman with healthy ovaries was artificially inseminated with sperm from the husband of an infertile woman. Five days after fertilization, the donor's uterus was flushed with a nutrient solution and the embryo was recovered and implanted in the infertile woman's uterus...
