To identify which methods used in the assessment of the ovarian reserve are exclusive or complementary to identify the best response to follicle development.
Retrospective cohort study, involving patients undergoing assisted reproduction treatment at the Instituto de Medicina Reprodutiva e Fetal, from April 2009 to July 2014. Age, biochemical tests, and ultrasound were assessed. The data were analyzed to predict the follicular development and the relation between them, using, for statistical analysis, Statistical Package for Social Sciences software.
Out of the 293 couples included, 50.2% presented infertility by ovarian factor. Considering the age as the main variable, a significant negative correlation with the volume of both ovaries was observed (right ovary, r = 0.21; left ovary, r =0.22; both p< 0.0001), and with the antral follicle count (right ovary, r =0.38; left ovary, r =0.47; both p< 0.0001). Considering the antral follicle count as the main variable, a significant positive correlation with the total recruited oocytes was observed. When we correlated the antral follicle count with the recruited follicles larger than 18 mm, we observed that, with a cutoff of 12 antral follicles, there is a positive predictive value of 99%, and an area under the ROC curve of 0.76.
We concluded from our study that age and antral follicle count are effective predictors of ovarian response in cycles of assisted reproduction. The ovarian volume, as well as the anti-Müllerian hormone dosage, seem to be adequate markers of the ovarian reserve.

PURPOSE: To evaluate the sonographic parameters related to morphological characteristics of pelvic adnexal masses by obtaining two-dimensional images by an observer presence, forwarded electronically (via tele-ultrasound) in static and dynamic modes observers do not face (distance) for comparative analyzes inter intraobserver and to the validation of a second opinion. METHODS: From March to August 2010 were selected 50 patients with adnexal mass viewing of the pelvic ultrasound. They were subjected to ultrasound for abdominal and transvaginal routes. The images were captured in static and dynamic modes, electronically forwarded for evaluation of non-presence and two examiners evaluated according to morphological ultrasonographic parameters previously determined. RESULTS: The evaluators did not face in static and dynamic modes obtained almost perfect agreement for all morphological parameters with Kappa values between 0.6 and 0.8. There was no difference between the methods employed, except for the morphological parameter papillary projection in the static mode , in which the agreement was almost perfect ( 0.8 ) while in dynamic mode was substantial (0.6). CONCLUSIONS: The sonographic parameters of the features of adnexal masses pelvic sent by tele-ultrasound are capable of being validated for issuing a second opinion. There were no significant differences in the methodology used in the issue of tele-ultrasound images (static or dynamic) to characterize the composition of pelvic adnexal masses.

OBJECTIVE: to determine GSTT1 and GSTM1 null genotype frequencies as well as CYP1A1 polymorphic allele frequencies in a group of women with endometriosis, and to compare these frequencies with those observed in a group without endometriosis (control), aiming at a possible identification of biomarkers of susceptibility to endometriosis. METHODS: a total of 50 women with suggestive clinical signs of endometriosis underwent videolaparoscopy and biopsies were evaluated histologically. Endometriosis was present in 25 women (case group). Negative results were found in 25 women (control group). GSTT1 and GSTM1 null genotypes were assessed by multiplex polymerase chain reaction (PCR). The investigation of the polymorphic allele of the gene CYP1A1 was performed by PCR-RFLP (restriction fragment length polymorphism). For statistical analysis, the Fisher exact test was used. RESULTS: in both groups, the deletion polymorphism frequencies presented values of 16% for the gene GSTT1 and of 44% for the gene GSTM1; therefore, the results did not show differences in the distribution of the GSTT1 and GSTM1 null genotypes among the studied groups. The allelic frequency for the m1 allele of the gene CYP1A1 was higher in the women with endometriosis (0.22), although not statistically significant, when compared to the control group (0.14). CONCLUSION: the results did not show an association between the evaluated polymorphisms and the endometriosis diagnosis.
