Microsurgery requires the basic understanding of tubal physiology. Before a patient undergoes a microsurgical procedure, she and her husband should have completed an infertility workup. This may include a diagnostic laparoscopy to determine the length of the tube remaining on each side. Microsurgical techniques are now being used with increased success for accurate anastomosis of the fallopian tube. The average time between reversal surgery and pregnancy is 10 months.
