Abstract

OBJECTIVE
To assess the clinical efficacy of intraovarian artery stromal Doppler ultrasonography and serum glycodelin (placental protein 14, PP14) as prognostic factors of pregnancy in in vitro fertilization and embryo transfer (IVF-ET) cycles.
METHODS
Fifty seven infertile women undergoing IVF-ET were recruited at SNUH from April, 2003 to March, 2004. All IVF-ET patients received controlled ovarian hyperstimulation (COH) using gonadotropins with either GnRH agonist or GnRH antagonist. Doppler ultrasonographic measurements were performed by Sonoace-8800 (Medison) with 5.5 MHz transvaginal probe. Pulsatility Index (PI) of intraovarian stromal artery was evaluated on the first day of ovarian stimulation and the day of hCG administration. Blood sampling for hormonal assay including PP14 was taken at the time of the first day of ovarian stimulation, hCG administration, oocyte retrieval, and embryo transfer (ET). Serum hormonal profiles, PI, and outcomes of COH and IVF-ET were compared between clinically pregnant (n=12) and nonpregnant (n=45) groups.
RESULTS
Demographic and clinical characteristics of the patients were comparable in both groups except body mass index (BMI). There was no significant correlation between BMI and serum PP14 levels or PI measured in intraovarian stromal artery. Pregnant group had significantly higher fertilization rate and larger number of cryopreserved embryos. The mean serum levels of estradiol, progesterone, LH and FSH were not different between the two groups. When compared with the nonpregnant group, serum PP14 levels were lower in the pregnant group throughout the treatment cycle, but there was no statistical significance. PI of intraovarian stromal artery on hCG day was significantly lower in the pregnant group (1.2 +/- 0.4 vs. 1.8 +/- 0.8). There was no significant correlation between serum PP14 levels and PI.
CONCLUSION
This study suggests that serum PP14 levels cannot be a prognostic factor in IVF-ET. The development of more sensitive assay method is required. PI of intraovarian stromal artery on hCG day can be clinically more useful in predicting the success of IVF-ET.
