“…However, the high individual variation in the present results shows that these parameters are not useful as a predictor of IVF/ICSI outcome. Lorenz-Eberhardt et al [12] untersuchten 72 Follikelflüssigkeiten und ebenso viele Oozyten und bestimmten den mittleren Gesamt-Bilirubingehalt in der Follikelflüssigkeit von reifen, mittelreifen und unreifen Eizellen (0,2043 mg/dl zu 0,2302 mg/dl zu 0,1830 mg/dl). Auûerdem bestimmten sie den Gesamt-Bilirubingehalt in der Follikelflüssigkeit fertilisierter und nicht fertilisierter Oozyten (0,2062 mg/dl zu 0,2417 mg/dl).…”

The aim of this study was to determine the relationship between the ovarian stimulation protocol (with HMG or FSH) after down-regulation with GnRH anologa and protein (total protein and albumin) as well as bilirubin and urea in serum. Furthermore, it was intended to find out the effect of these parameters on IVF/ICSI outcome. 50 patients were included in this study. All patients underwent controlled ovarian hyperstimulation for assisted reproduction therapy either with FSH (Gonal-F) or HMG (Menogon). Ovulation induction was induced by human chorionic gonadotrophine (HCG, Predalon) 10 000 IU i. m. The protein concentration (total protein, albumin) as well as bilirubin and urea concentrations were determined before down-regulation with GnRHa, at the beginning of ovarian stimulation with FSH or HMG, on the day of ovulation induction with HCG, during oocyte retrieval and fourteen days after embryo transfer. The age, body mass index and etiology of infertility showed no significant difference between patients stimulated with HMG or FSH. Total protein and albumin concentration decreased significantly (p=0.001) from 77.45 +/- 5.90 g/L and 47.02 +/- 3.41 g/L to 74.60 +/- 4.6 g/L and 45.04 +/- 2.39 g/L, respectively at the time of oocyte retrieval. Whereas, no significant change with bilirubin and urea concentration was observed. However, the mean concentration of total protein, albumin, bilirubin of patients who become pregnant was higher of those who did not. In conclusion, this study shows that total protein and albumin concentration in plasma decreased during the follicular phase significantly with the application of exogenous gonadotrophins and steroid hormones in comparison to the value before down-regulation. The mean value of total protein, albumin, bilirubin of patients who become pregnant was higher (but not significant) of those who did not. However, the high individual variation in the present results shows that these parameters are not useful as a predictor of IVF/ICSI outcome.
