Purpose: to assess ovarian reserve by FSH determination on the 3rd day of the menstrual cycle compared to the clomiphene test and to correlate the results with the ovarian response to controlled hyperstimulation with gonadotrophins for in vitro fertilization. Methods: a total of 49 patients older than 30 years who had been presenting a clinical picture of infertility for at least 1 year were selected. All patients were evaluated for ovarian reserve by the clomiphene citrate test and 26 of them were later submitted to controlled ovarian hyperstimulation with gonadotrophins. Of these 26 patients, 18 showed a good response to ovarian hyperstimulation and 8 showed a poor response. Mean (+ SD) FSH values were calculated for the determinations on the 3rd and on the 10th day and for their sum in the group of patients who responded favorably to ovarian stimulation, and were later correlated with the ovarian response after gonadotrophin stimulation. Results: employing a FSH value > 16.1 IU/mL on the 10th day (mean plus 2 SD) for the prediction of a poor ovarian response in the clomiphene test, the sensitivity, specificity, and positive and negative predictive values of this parameter were 50, 100, 100 and 81.8%, respectively. Considering the clomiphene test to be positive when the sum of the FSH values determined on the 3rd and 10th day plus 2 SD was > 22.6 IU/mL, we obtained 62.5% sensitivity 100% specificity, 100% positive predictive value, and 85.7% negative predictive value. A single FSH determination of 10 IU/mL on the 3rd day of the cycle for the prediction of a poor ovarian response showed 87% sensitivity, 100% specificity, 100% positive predictive value and 94.7% negative predictive value. Conclusion: in the present study, a single FSH determination on the 3rd day of the cycle showed to be more sensitive than the clomiphene test for the evaluation of ovarian reserve.

OBJECTIVE: to assess the ovarian response of poor responsive patients, submitted to the bromocriptine method. PACIENTS AND METHODS: a prospective clinical trial for the in vitro fertilization (IVF) program was performed in 10 poor responsive patients. Endocrinologically normal ovulatory women under 38 years old, who had previously failed in IVF due to poor response to ovarian stimulation with the traditional protocol, were submitted to the bromocriptine method in 12 cycles. They were given bromocriptine, a dopaminergic agonist, in the preceding cycle in order to stop the prolactin production. When the medication was removed at the beginning of the stimulation cycle, an elevation of seric prolactin by a rebound phenomenon was found. This optimized its seric concentration, improving the quality of oocytes and embryos. Serum prolactin and estradiol concentrations, number of follicles, number and quality of oocytes and cleaved embryos, fertilization and pregnancy rates were analyzed. RESULTS: there was a reduction in the dose of gonadotropin administered and in the duration of ovarian stimulation and an improvement in follicular recruitment, oocyte retrieval, embryo morphology, fertilization, and ongoing pregnancy rates. Fertilization rate was 77.7%, pregnancy rate was 44.4% and live baby rate was 25%. CONCLUSION: this study suggests that the bromocriptine method enhanced follicular recruitment and embryonic development, resulting in increased fertilization and pregnancy rates when compared with the traditional protocol for poor responsive patients. Studies with a large number of patients are necessary to confirm these results.

Purpose: to compare the methods used to investigate the endouterine cavity by testing the sensitivity and specificity of X-ray hysterography and sonohysterography compared with hysteroscopy (gold standard). Methods: we carried out a prospective study with 18 patients who, due to symptoms such as irregular menstrual cycles, unexplained postmenopausal uterine bleeding and ultrasound disturbance, were candidates for uterine cavity investigation by X-ray hysterography, sonohysterography and hysteroscopy. Results: sonohysterography sensitivity and specificity were 90 and 87.5%, respectively. Positive and negative predictive values were 90 and 87.5%. For X-ray hysterography, sensitivity, specificity, positive and negative predictive values were 70, 75, 77.7 and 75%, respectively. Conclusion: the use of saline instilation into the endometrial cavity in order to enhance the acuracy of the vaginal ultrasonography seems reliable as a mean to distinguish lesions in the uterine cavity, thereby facilitating the identification of candidates for diagnostic or operative hysteroscopy. X-ray hysterography produces results inferior to hysterosonography.
