The widespread use of ultrasound for follicle development assessment and ovum pickup has raised concerns about the theoretical possibility of adverse effects on oocyte function. Studies in other species do not demonstrate any adverse effects when using sonic energies as those presently used in diagnostic ultrasound. However, no data are available concerning the effects of diagnostic ultrasound on human preovulatory oocytes. This study was conducted to determine whether there were any adverse effects on the reproductive function of oocytes using transvaginal ultrasonography. No effect on fertilization and subsequent cleavage of oocytes was demonstrated. This method can, therefore, be recommended for follicle assessment and as a better alternative to laparoscopy for oocyte retrieval.
