Outcome of in vitro fertilization-embryo transfer in treatment of polycystic ovarian syndrome / 浙江大学学报·医学版

<p><b>OBJECTIVE</b>To evaluate the outcome of in vitro fertilization embryo transfer (IVF-ET) in treatment of polycystic ovarian syndrome (PCOS) with infertility.</p><p><b>METHODS</b>A retrospective analysis was performed from 52 patients with PCOS (PCOS group) and 408 cases with tubal infertility (control group). Both groups underwent IVF-ET treatment from 2001 to 2004. The duration of stimulation, amps of gammaFSH, the level of serum E2, P on the day of HCG injection, the number of oocytes retrieved, the rates of fertilization, cleavage, implantation and pregnancy, the incidence of ovarian hyperstimulation syndrome (OHSS) and cancelled rate of ET were compared between the two groups.</p><p><b>RESULT</b>The duration of stimulation and amps of gammaFSH were not significantly different between the two groups. The concentration of serum E2, P on the day of HCG injection, the numbers of oocytes retrieved and cleavaged embryos were significantly higher in PCOS group (P <0.01, <0.05). Fertilization rate was significantly lower in PCOS group (P <0.01). The implantation, pregnancy and miscarriage rates per ET were not statistically significant. The OHSS rates and cancelled rates of ET were higher in PCOS group (P <0.01).</p><p><b>CONCLUSION</b>Women with PCOS have a lower fertilization rate compared with those with tubal-factor fertility during IVF-ET. However, more oocytes are recovered and the preimplanted embryo has a normal chance of implantation leading to similar pregnancy rates. The OHSS rates and cancelled rates of ET are higher in PCOS because of a greater number of oocytes developed and a higher level of E2.</p>

Resistin levels of serum and follicular fluid in non-obese patients with polycystic ovary syndrome during IVF cycles / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

<p><b>OBJECTIVES</b>To measure serum and follicular resistin, steroids hormone levels in women with PCOS (polycystic ovary syndrome) (BMI (body mass index)<25 kg/m(2)), to assess possible correlations of resistin to hormonal and metabolic parameters and to analyze the clinical outcomes of in vitro fertilization-embryo transfer (IVF-ET) in women with PCOS and tubal infertility.</p><p><b>STUDY DESIGN</b>We analyzed the clinical outcomes of IVF-ET in women with PCOS (BMI<25 kg/m(2)) and tubal infertility during the years 2002 to 2004 and compared the serum and follicular fluid resistin levels, estradiol (E(2)), progesterone (P), testosterone (T) levels in 20 PCOS and 20 healthy, age-matched women without PCOS during IVF-stimulated cycles. The correlations between the resistin levels and the outcomes of IVF-ET were evaluated.</p><p><b>RESULTS</b>No significant differences in resistin levels of either serum or follicular fluid between PCOS and control group were found. However, resistin levels in serum were higher than that in follicular fluid in both groups. Multiple regression analysis showed that resistin levels in serum did not correlate with BMI, estradiol, LH (luteinizing hormone) and insulin level in fasting blood. No significant correlations were found between follicular fluid reisistin levels and fertilization rate, implantation rate, clinical pregnancy rate or early miscarriage rate in both PCOS and control groups.</p><p><b>CONCLUSION</b>Our results show that resistin does not have correlation with the hormonal and metabolic parameters as well as the outcomes of IVF. These data suggest that resistin is unlikely to be a local determinant factor in steroidogenesis and growth and maturation of oocytes during IVF-ET in lean women with PCOS.</p>
