- Abstract
Backgrounds: This case-control study was designed to assess the possible role of fetuin-A, a multifunctional protein, in reproductive processes of women undergoing in vitro fertilization (IVF). Methods: Paired serum and follicular fluid (FF) samples were obtained from 35 unselected patients who received IVF treatment. Their main clinical chartacteristics: age 35.2±5.4 years, BMI 22.9±2.8, duration of infertility 3.2±2.0 years, gonadotropin administered 1199.4±202.3 IU, and estradiol level on day 6 of stimulation 1827±1342 pmol/L. In total 25 healthy women of similar age admitted for minor elective surgery served as controls for serum analysis. Fetuin-A and high-sensitivity C-reactive protein (hsCRP) were measured in serum and FF by using commercially available ELISA kits and turbidimetric immunoassay, respectively. Results: Serum fetuin-A levels of patients participating IVF are markedly elevated when compared to those of healthy women (1.30±0.58 g/L vs. 0.55±0.09 g/L, p<0.000). Fetuin-A in FF proved to be comparable to its serum levels (1.17±0.45 g/L) and no relationship could be detected between the respective individual values. Moreover, markers of reproductive potential (number of oocytes and embryos) appeared to be independent of serum and FF fetuin-A. hsCRP in serum and FF was not related to fetuin-A and did not influence the number of oocytes and embryos. Conclusions: Fetuin-A concentration is high in FF of patients undergoing IVF, however, it can not be used as an estimate of fertilization success.
