PURPOSE: to evaluate the effects of the association of estrogen and androgen on the quality of life and sexuality of women during climacterium. METHODS: ninety-six postmenopausal women with vasomotor symptoms and sexual dysfunction were included. The participants were randomly divided into three treatment groups with 32 pacients each: placebo, conjugated equine estrogens (CEE) (0.625 mg per day) and CEE (0.625 mg per day) associated with methyltestosterone (2.5 mg per day). The length of the treatment period was three months. The Women Health Questionnaire (WHQ) and the Modified Sexuality Questionnaire were applied to evaluate the quality of life and sexuality before and after the treatment. Some parameters of cardiovascular risk, endometrial echo and hepatic toxicity were evaluated. ANOVA was used for data analysis followed by the Fisher test and the Shapiro-Wilk post hoc test. RESULTS: the improvement in WHQ parameters was significant in the hormonal treatment groups (CEE and CEE + methyltestosterone) compared to the placebo group. However, there were no differences in somatic symptoms among the three groups. The association of estrogen with androgen significantly improved sexual function (score (mean): 64 vs 67, p<0.05) and depressive humor (score (mean): 75 vs 80, p<0.05) compared to estrogen alone. This therapy also presented a large number of WHQ questions with a high score (p<0.05). The use of CEE associated with methyltestosterone decreased the total cholesterol (212±42 and 194±43, before and after the treatment, respectively) and HDL colesterol (56±16 and 48±14, before and after the treatment, respectively), and slightly increased the endometrial echo (4.7±2.3 and 5.5±2.3, before and after the treatment, respectively). No signifcant changes in liver enzymes during the treatment period was detected. CONCLUSIONS: estrogen associated with methyltestosterone resulted in significant improvement in the quality of life and sexuality of postmenopausal women. This effect was superior to estrogen alone and placebo. The effect of treatment with the estrogen-androgen association was evident regarding depressive humor and sexual function questions of the WHQ.

PURPOSE: to determine the efficacy and safety of dinoprostone and misoprostol for the induction of vaginal childbirth, with or without the use of oxytocin in nulliparous women. METHODS: in this retrospective observational study, 238 patients were subjected to the induction of delivery from January 2008 to February 2010 with the use of misoprostol 25 mcg by the vaginal route or a pessary containing 10 mg of dinoprostone. A total of 184 patients were selected, with the following characteristics: nulliparous, gestational age of 37-42 weeks, singleton pregnancies, cephalic presentation, intact membranes, and Bishop score < 3. Obstetric and neonatal data were analyzed and compared between groups. The Student t-test, chi-square test and Fisher's exact test were used for statistical analysis, with the level of significance set at p<0.05. RESULTS: the rate of vaginal childbirth did not differ significantly in patients who used misoprostol and dinoprostone (43.2% versus 50%; p = 0.35, respectively). The ripening of cervix was higher in the group treated with misoprostol (87.3% versus 75.6%, p=0.04). The use of oxytocin was necessary in 58.8% of the misoprostol group and 57.3% in the dinoprostone group after the ripening of cervix. Failed induction was the primary indication of caesarean section delivery in both groups, with no significant difference between them. Fetal and maternal adverse events, such as tachysystole and Apgar scores were similar. CONCLUSION: dinoprostone and misoprostol are both effective for vaginal childbirth induction, although they need to be combined with oxytocin. They showed a similar safety profile, with misoprostol being more efficient regarding cervical ripening.

PURPOSE: to compare the serum levels of five markers of oxidative stress and assisted reproduction (AR) outcomes among infertile patients, with tubal and/or male factor and with polycystic ovary syndrome (PCOS). METHODS: 70 patients were included, 58 with tubal and/or male factor infertility and 12 with PCOS, who underwent controlled ovarian stimulation to perform intracytoplasmic sperm injection (ICSI). A blood sample was collected between the third and fifth day of the menstrual cycle in the month prior to ovarian stimulation. We analyzed the levels of malondialdehyde, hydroperoxides, protein oxidation products, glutathione and vitamin E, by reading the absorbance with a spectrophotometer and by high performance liquid chromatography (HPLC). Data were analyzed statistically by the Student's t-test and Fisher's exact test. RESULTS: significant increases in the body mass index, ovarian volume and number of antral follicles were observed in PCOS patients, as well as the use of a lower total dose of follicle stimulating hormone for these patients. There were no differences in the response to ovarian stimulation, in the results of AR or serum levels of malondialdehyde, hydroperoxides, advanced oxidation protein products, glutathione and vitamin E between groups. CONCLUSIONS: the present data did not demonstrate a difference in the levels of serum markers of oxidative stress or in AR results when comparing non-obese infertile patients with PCOS and controls. These data suggest that the results of AR may not be compromised in this specific subgroup of patients with PCOS. However, interpretations of the action of oxidative stress on the results of AR are still not clear and the reproductive implications of oxidative stress need to be better evaluated.
