Abstract
Purpose: To compare the efficiency of transvaginal ultrasound-guided functional ovarian cyst aspiration, withconservative management, in the outcome of patientsundergoing assisted reproductive technique (ART) (in vitrofertilization or intracytoplasmic sperm injection). Thesecysts were identified before ovarian stimulation begun andafter administration of a midluteal GnRH agonist.
Methods: Fifty nine patients undergoing ART from January1, 1997 to February 28, 1999, who developed functionalovarian cysts were included. Aspirations of these cysts(n = 14) versus conservative management(n = 45) were compared. Total number of ovarian folliclesdeveloped, number of oocytes retrieved, estradiol levels onthe day of human chorionic gonadotropin, fertilization rate,number of good quality embryos transferred, implantation,and clinical pregnancy rate per cycle were evaluated.
Results: No statistical differences were observed betweenthe two groups in any of the selected parameters.
Conclusions: Cyst aspiration and conservative managementshowed similar implantation and pregnancy rates, in patientswho develop functional ovarian cysts after pituitarydown-regulation following luteal phase gonadotropin-releasinghormone agonist administration. Prospective studies areneeded to confirm this trend.
Keywords: assisted reproductive technique, transvaginal aspiration, functional ovarian cysts, GnRH agonists; ovarian stimulation
