Fertilization rate during intracytoplasmic sperm injection procedure comparing 6 and 12 O’clock polar body position.

A Prospective study was designed to compare fertilization rate between the . and 12 o’clock position of the polar body during the intracytoplasmic sperm injection (ICSI) procedure. A total of 128 oocytes were injected by placing the first polar body at 6 o’clock and 12 o’clock alternately. Normal fertilization rates were 70.31 and 71.87 percent respectively. There was no statistical significance between the two groups.
