BACKGROUND A poor quality of oocytes and embryos and a low fertilization rate have been found in polycystic ovary syndrome (PCOS) patients. An inverse association between follicular fluid homocysteine (Hcy) levels and oocyte and embryo quality has also been demonstrated. We examined the relationship between follicular fluid Hcy concentrations and oocyte and embryo quality in PCOS patients undergoing assisted reproduction. METHODS Fifty-two PCOS patients were included in the study, and underwent GnRH agonist/recombinant FSH treatment. The Hcy, folate, vitamin B(12), malonyldialdehyde (MDA) and estradiol (E(2)) levels were measured in follicular fluid from single oocytes at time of retrieval. One follicle per ovary was sampled and 94 were analysed. Plasma hormones were also measured. Oocytes and embryos were graded (1-3) using standard approaches. RESULTS The concentrations of Hcy, E(2), vitamin B(12), folate and MDA in plasma were higher than in follicular fluid (all P < 0.001). Significant differences were observed in follicular Hcy levels between Grade 3 and Grade 2 oocytes (P < 0.001). Hcy levels were lower in Grade 1-2 embryos than that in Grade 3 embryos; follicular fluid vitamin B(12) levels were lower in patients showing high concentrations of follicular fluid Hcy (P < 0.01). The follicular fluid Hcy levels were negatively correlated with follicular fluid vitamin B(12) (r = -0.44), folate (r = -0.68) and fertilization rate (r = -0.85), and positively correlated with follicular fluid MDA (r = 0.51). CONCLUSIONS Concentrations of Hcy in follicular fluid on the dOPU may be a useful marker for fertilization rate, and oocyte and embryo quality in PCOS patients undergoing assisted reproduction.

OBJECTIVE To compare the efficacy of microdose GnRH agonist (GnRH-a) flare-up and multiple dose GnRH antagonist protocols in patients who have a poor response to a long luteal GnRH-a protocol. DESIGN Prospective, randomized, clinical study. SETTING University hospital. PATIENT(S) Forty-two poor responder patients undergoing intracytoplasmic sperm injection (ICSI)-embryo transfer cycle. INTERVENTION(S) Twenty-one patients received microdose leuprolide acetate (LA) (50 microg twice daily) starting on the second day of withdrawal bleeding. The other 21 patients received 0.25 mg of cetrorelix daily when the leading follicle reached 14 mm in diameter. MAIN OUTCOME MEASURE(S) Serum E(2) levels, number of growing follicles and mature oocytes, embryo quality, dose of gonadotropin used, cancellation, fertilization, implantation rate and pregnancy rate (PR). RESULT(S) The mean serum E(2) concentration on the day of hCG administration was significantly higher in the microdose GnRH-a group than in the GnRH antagonist group (1,904 vs. 1,362 pg/mL). The clinical PRs per started cycle of microdose GnRH-a and GnRH antagonist groups were 14.2% and 9.5%, respectively. There were no statistically significant differences in the other ovulation induction characteristics, fertilization and implantation rates. CONCLUSION(S) Microdose GnRH-a flare-up protocol and multiple dose GnRH antagonist protocol seem to have similar efficacy in improving treatment outcomes of poor responder patients.

OBJECTIVE To determine serum interleukin (IL)-18 levels and to find out whether IL-18 is associated with carotid intima-media wall thickness (IMT) and various cardiovascular risk factors in women with polycystic ovary syndrome (PCOS). DESIGN A prospective, controlled study. SETTING University hospital. PATIENT(S) Sixty women with PCOS and 60 healthy women were included this study. INTERVENTION(S) Serum levels IL-18, homocysteine (Hcy), C-reactive protein (CRP), IL-6, malonyldialdehyde (MDA), lipid and hormone profiles were measured. Carotid IMT was evaluated for both common carotid arteries. MAIN OUTCOME MEASURE(S) Serum IL-18, carotid IMT, Hcy, CRP, IL-6, MDA, and homeostasis model assessment of insulin resistance. RESULT(S) The evaluation, which was made without the obesity influence taken into consideration, revealed that patients with PCOS have increased serum IL-18 levels than that of the control group (214 +/- 102 vs. 170 +/- 78 pg/mL). The interaction between PCOS and obesity was seen to have statistical significance (F = 67.8). Body mass index (BMI), waist to-hip ratio, Hcy, and homeostasis model assessment of insulin resistance are independent determinants of plasma IL-18 in patients with PCOS. Elevated serum IL-18 levels were positively and significantly correlated with a greater carotid IMT. For Hcy and carotid IMT, the interaction between PCOS and obesity was found in a two-way ANOVA variation analysis (F = 48.5 and F = 81.5, respectively). CONCLUSION(S) Elevated serum IL-18 levels were associated with cardiovascular risk factors and carotid IMT in patients with PCOS.

OBJECTIVE To determine the possible relationship between serum antimüllerian hormone (AMH) concentrations on day 3 and controlled ovarian stimulation and reproductive outcomes in women with polycystic ovary syndrome. DESIGN Prospective, clinical trial. SETTING University hospital. PATIENT(S) Sixty women with PCOS. INTERVENTION(S) Serum concentrations of AMH measured on cycle day 3. MAIN OUTCOME MEASURE(S) Clinic pregnancy rate (CPR), implantation rate (IR), and fertilization rate (FR). RESULT(S) The CPR, IR, and FR were markedly different among the day-3 serum AMH groups (low, moderate, and high AMH groups). The CPR were 33.3, 46.1, and 60.0, respectively, in the low, moderate, and high serum AMH groups on day 3. The embryo IR were 18.6, 26.7, and 36.3, respectively. The FR were 54, 68, and 79, respectively. An AMH level≥3.01 ng/mL was shown to predict FR with a sensitivity of 86.4% and specificity of 75%. An AMH level≥3.2 ng/mL was shown to predict IR and CPR with sensitivity and specificity of 72.1% and 72.7%, and 75.6% and 77.3%, respectively. CONCLUSION(S) On day 3 of the in vitro fertilization stimulation cycle, serum concentrations of AMH can be used as a marker for ovarian response as well as reproductive outcome in assisted reproductive cycles of PCOS patients.

BackgroundThromboembolism is a rare but extremely serious complication of ovarian hyperstimulation syndrome.Case reportWe report a case of left internal jugular vein thrombosis, presenting as a late complication of moderate ovarian hyperstimulation syndrome.ConclusionPrevention of vascular thrombosis should be a part of the treatment in the setting of assisted reproductive procedures complicated with ovarian hyperstimulation syndrome.

OBJECTIVE To determine the potential effect of the ultrashort gonadotropin-releasing hormone (GnRH) agonist/GnRH antagonist protocol versus the microdose GnRH agonist protocol in poor responders undergoing intracytoplasmic sperm injection (ICSI). MATERIAL AND METHODS The patients in the Agonist-Antagonist Group (n=41) were administered the ultrashort GnRH-agonist/ antagonist protocol, while the patients in the Microdose Group (n=41) were stimulated according to the microdose flare-up protocol. The mean number of mature oocytes retrieved was the primary outcome measure. Fertilization rate, implantation rate per embryo and clinical pregnancy rates were secondary outcome measures. RESULTS There was no differenc between the mean number of mature oocytes retrieved in the two groups. There were also no statistical differences between the two groups in terms of peak serum E2 level, canceled cycles, endometrial thickness on hCG day, number of 2 pronucleus and number of embryos transferred. However, the total gonadotropin consumption and duration of stimulation were significantly higher with the Agonist-Antagonist Group compared with the Microdose Group. The implantation and clinical pregnancy rates were similar between the two groups. CONCLUSION Despite the high dose of gonadotropin consumption and longer duration of stimulation with the ultrashort GnRH agonist/ antagonist protocol, it seems that the Agonist-Antagonist Protocol is not inferior to the microdose protocol in poor responders undergoing ICSI.
