PURPOSE: to evaluate three embryo scoring systems specific for 3-day embryos and to correlate them with positive in vitro fertilization outcome. METHOD: retrospective study of the In Vitro Fertilization Program of the University Hospital, Faculty of Medicine of Ribeirão Preto, University of São Paulo. A total of 137 patients submitted to the transfer of 439 embryos were evaluated. The main outcomes measured were pregnancy and implantation rates. RESULTS: a significant difference in the three scoring systems was observed between pregnant (n=53) and non-pregnant (n=84) patients (p<0.0001). In the first embryo scoring system, in which cell number alone was used, higher pregnancy (70%) and implantation rates (42%) were observed when embryos with a mean blastomere number higher than 8 were transferred. Scoring system 2, based on a total four-point score (cleavage stage, blastomere number, fragmentation and symmetry), showed increased pregnancy (52.8%) and implantation rates (31%) for scores above 2. Scoring system 3, based on cell number and morphological criteria, also showed higher pregnancy and implantation rates with increasing average scores of the transferred embryos. CONCLUSION: the three scoring systems assessed in 3-day embryos were positively correlated with pregnancy and implantation rates.

PURPOSE: to assess the level of lipid peroxidation (LP) and vitamin E in the follicular fluid and serum of infertile patients, with or without endometriosis, submitted to induction of ovulation for assisted reproduction procedures. METHODS: infertile patients aged 20 to 38 years old were selected prospectively and consecutively and divided into Endometriosis Group (17 patients with pelvic endometriosis) and Control Group (19 patients with previous tubal ligation or with male factor). Blood samples were collected on: D1 (before the beginning of the use of gonadotrophins), D2 (day of human chorionic gonadotrofin application) and D3 (day of oocyte retrieval). On D3, follicular fluid samples free from blood contamination were also collected and stored. LP was assessed for malondialdehyde (MDA) quantification by spectrophotometry, and antioxidant status by measurement of vitamin E by HLPC. RESULTS: on D1, no significant difference in LP was observed between groups. However, vitamin E levels were significantly higher in the Control Group. On D2, LP levels were significantly higher in the Endometriosis Group compared to Control and vitamin E levels continued to be significantly higher in the Control Group. On D3, there was no significant difference in both serum and follicular fluid levels of LP or vitamin E between groups. However, on D3, vitamin E levels were found to be significantly higher in serum than in follicular fluid in both groups, whereas MDA levels were significantly lower in follicular fluid than in serum only in the Control Group. CONCLUSION: before the beginning of the induction of ovulation, a significant decrease in antioxidant status was observed in patients with endometriosis, perhaps because antioxidants are consumed during oxidation reactions. After the induction of ovulation with exogenous gonadotrophins, the group of patients with endometriosis presented not only increased lipid peroxidation compared to Control, but also maintained a lower antioxidant status than the Control Group. However, on the day of oocyte retrieval, both serum LP potential and the levels of vitamin E were found to be similar in both groups.

PURPOSE: to evaluate the use of natural latex mold (Hevea brasiliensis) as a modification of McIndoe and Bannister neovaginoplasty in patients presenting Mayer-Rokitansky-Küster-Hauser (MKRH) syndrome. METHODS: we retrospectively included nine patients presenting MKRH syndrome, who had been submitted to McIndoe and Bannister neovaginoplasty modified by the use of natural latex mold. Neovaginal epithelization and depth, coitus occurrence and satisfaction, and surgical complications were evaluated. RESULTS: five weeks after the procedure, eight patients presented an epithelized 7 to 12 cm deep neovagina. There was one case of complete neovaginal stenosis, because of incorrect use of the mold. After at least one year, the others maintained 4 to 8 cm deep neovaginas and capacity for intercourse, with 66.7% satisfaction. One woman presented precocious rectovaginal fistula and late episodes of uretrovaginal fistulae. Two patients presented distal neovaginal stenosis in long-term follow-up. One of these and the patient with fistulae were submitted to a new procedure. CONCLUSIONS: the use of natural latex mold as a modification of classic neovaginoplasty technique allows the creation of neovaginas morphologically and functionally similar to the normal vagina in patients with vaginal agenesis.

PURPOSE: to evaluate the rate of chemically diagnosed pregnancy (serum beta-HCG>25 mIU/mL levels obtained fourteen days after the embryonic transfer) clinically diagnosed pregnancy (gestational sac visualized by ultrasound four to six weeks after the embryonic transfer) and miscarriage rates in women submitted in vitro fertilization to (IVF) and intracytoplasmic sperm injection (ICSI) in a tertiary center of assisted reproduction and to correlate these rates with age. METHODS: retrospective transverse study with analysis of 1016 cycles of controlled ovarian hyperstimulation of 932 infertile women with indication of IVF (370 cycles) or ICSI (646 cycles). The patients' age ranged from 22 to 46 years. All women with age over 35 years included in the study had FSH<15 IU/L. The studied cycles were divided into two groups: the first including the cycles referring to women of 22 to 30 years and the second group, to those of 31 to 46 years. The studied variables were: pregnancy (chemical or clinical) and miscarriage rates. The chi2 test was used to compare these rates between the groups. RESULTS: the total pregnancy rate was 36.42%, with a significant reduction starting at 30 years (p=0.0001). From 22 to 30 years (303 cycles) the pregnancy rate was 45.4%, while in the range from 31 to 46 years (713 cycles), it was 25.1%. The miscarriage rates were, 10.2 11,6%, respectively (p=0.6854). CONCLUSION: although the miscarriage rates did not differ between the groups, a decrease in the pregnancy rate of infertile women submitted to IVF or ICSI was observed after the age of 30 years. Thus, we recommend the gynecologists not to postpone the investigation and the referral for treatment of infertility.

PURPOSE: to study the histological modifications that occur in the endometrium of women before and six months after tubal ligation (TL) and to correlate these findings with progesterone (P4) levels. METHODS: the study was conducted on 16 women with normal menstrual cycles who were evaluated before and in the sixth cycle after TL. P4 levels were determined from the 8th day at 2-day intervals until ovulation and on the 8th, 10th and 12th day after ovulation or on the 24th day of the cycle. An endometrial biopsy was obtained between the 10th and 12th day after ovulation or on the 24th day of the cycle and a correlation with P4 was determined. Data were analyzed statistically by the nonparametric McNemar test for the evaluation of hormonal determination and by the exact Fisher test for the histological evaluation of the endometrium, with the level of significance set at p<0.05. RESULTS: mean age was 34.1±1.3 years. The intermenstrual interval was 27.1±2.6 days and the duration of bleeding was 3 to 5 days, with no difference between the studied periods. Before TL, 8/16 (50.0%) of the cases had a secretory endometrium according to the cycle, 3/16 (18.8%) had a secretory endometrium not according to the cycle and 3/16 (18.8%) had a dysfunctional endometrium, suggesting a defect in the luteal phase in 6/16 (37.5%). After TL, 7/16 (43.8%) had a secretory endometrium according to the cycle, 3/16 (18.8%) a secretory endometrium not according to the cycle and 4/16 (25.0%) had a dysfunctional endometrium, suggesting a defect in the luteal phase in 7/16 (43.8%). In 2/16 (12.5%) of the cases before TL and in 2/16 (12.5%) other cases after TL it was not possible to perform histological evaluation due to insufficient material or unspecfiic endometritis. In the luteal phase after TL, mean P4 levels were significantly lower on days +8, +10 and +12 than before TL, being 15.1, 18.0 and 20.7 ng/ml, respectively, before TL and 10.6, 8.0 and 5.4 ng/ml after TL (p<0.05). Before TL, 5/8 (62.5%) of the cases with a secretory endometrium according to the cycle had P4 >10 ng/ml and 3/8 (37.5%) had P4 <10 ng/ml. After TL, when the endometrium was secretory according to the cycle, P4 was >10 ng/ml in 4/7 (57.1%) and <10 ng/ml in 3/7 (42.9%). These differences were nonsignificant (p>0.05). CONCLUSION: six months after TL, the intermenstrual interval and the duration of bleeding were unchanged. P4 levels decreased during the luteal phase although this did not interfere in the endometrial response.

PURPOSE: to verify the efficacy of a single subcutaneous dose of cetrorelix acetate to avoid premature ovulation in assisted fertilization cycles. METHODS: this is a prospective, controlled and randomized study, with 20 women undergoing ovarian stimulation for assisted fertilization, 10 of whom were submitted to classical GnRH agonist protocol (control group) while 10 utilized a 3-mg subcutaneous dose of the GnRH antagonist on the 7th day of ovarian stimulation (cetrorelix group). Serum FSH, LH, estradiol and progesterone concentrations were assessed on the first, seventh, HCG administration and oocyte retrieval days. Both groups were compared for pituitary suppression (progesterone concentration on HCG day) and assisted fertilization cycle performance (gonadotropin ampoules utilized, follicles over 18 mm, retrieved oocytes, fertilization, implantation and pregnancy rates), utilizing Mann-Whitney and Fisher exact tests. RESULTS: no significant difference was observed between control and cetrorelix groups, respectively, for medians of age (31.5 and 34 years), body mass index (24 and 22), gonadotropin ampoles utilized (34 and 32), follicles over 18 mm (3.5 and 3.3), retrieved oocytes (11 and 5), obtained embryos (4 and 3), fertilization (93,7 and 60%, p=0.07) and pregnancy rates (50 and 60%, p=0.07). Efficient pituitary blockade through the ovarian stimulation period was observed for both groups. CONCLUSIONS: these results confirm the efficacy of a 3-mg dose of cetrorelix acetate to prevent premature ovulation in patients undergoing assisted fertilization and suggest a tendency towards a smaller number of embryos and fertilization rates in the cetrorelix group than in the control group. Implantation and pregnancy rates were similar between groups. Other prospective studies with a greater number of patients should be performed to confirm these results.

PURPOSE: to evaluate the results of neovaginoplasty with the use of a human amniotic graft in patients with the Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome. METHODS: the study was a retrospective analysis of a series of 28 patients with the MRKH syndrome conducted from 1990 to 2003. The patients were attended and treated at the Ambulatório de Ginecologia Infanto-Puberal (AGIP) of the Hospital Universitário of the Faculdade de Medicina de Ribeirão Preto of the Universidade de São Paulo (FMRP-USP), being submitted to neovaginoplasty by the technique of McIndoe and Bannister, modified by the use of a human amniotic membrane graft. Epithelization, amplitude and depth of the neovaginas were evaluated 7 and 40 days after the procedure. Patient satisfaction was determined during the late postoperative period in terms of the presence of discomfort and dyspareunia during sexual relations. RESULTS: postoperatively, seven patients (25%) presented vaginal stenosis and six of them were submitted to a new surgical intervention, one had shortening of the neovagina, corrected with the use of exercises with a vaginal mold, three (10.7%) developed a rectovaginal fistula, one (3.6%) a uterovesical fistula, and one (3.6%) excess skin in the vaginal introitus - all successfully corrected with surgery. Four patients (14.3%) presented urinary tract infection. Two months after surgery, 11/19 patients (57.8%) presented satisfactory sexual activity and 42% dyspareunia, and within a maximum period of four years, 20/21 patients (95.2%) had satisfactory sexual activity and 4.8% dyspareunia. CONCLUSIONS: an amniotic membrane graft is a good option for the treatment of vaginal agenesis. Perioperative follow-up involves educational guidance regarding the use of the mold and regarding patient sexuality in order to reduce the complaints of dysfunctional coitus in the presence of a favorable surgical evolution and a neovagina of adequate aspect.

PURPOSE: to check whether there were differences in some social indicators between adolescent and adult pregnant women in the city of Ribeirão Preto, from January 1992 to December 1996. METHODS: the information was obtained from hospital discharge forms and was analyzed at the Hospital Data Processing Center of the FMRP-USP. The analyzed parameters were: number and types of deliveries, category of hospital admission, occupation, and obstetric diagnosis. The 6.04a text processor Epi-Info System, a data bank and statistics of epidemiology produced by the Centers of Disease Control and Prevention (Atlanta, GA, USA), and Dbase IV were used to process the information. The association between variables was tested by the chi² test, with level of significance set at 5%, using the GraphPad Prism version 2.0, 1995 software. RESULTS: a total of 43,253 deliveries occurred during this period, among which 7,134 (16.5%) corresponded to adolescent deliveries, while 36,119 (83.5%) to adult deliveries. The number of deliveries by adolescent girls increased 25.5% along this period. The proportion of adolescent deliveries in the unified health system category of admission increased, and it was higher than that of the adults'. Only 14.1% of the adolescents belonged to the economically active population, comparing with 34.8% of the adults. Only 6.8% of the adolescents were students, while 79.0% were house-workers or had a nonpaid occupation. In the analyzed period, the ratio of vaginal delivery increased among the adolescents, as compared to that of the adults. The ratio of cesarean delivery persisted stable and higher among the adults. Premature delivery and false labor were significantly more frequent among the adolescents. CONCLUSION: the number of deliveries increased among the adolescents, and most of them were normal. The ratio of admission by the unified health system category and that of vaginal delivery were higher among the adolescents. There were more adolescents without an economically active work. Thus, we recommend strategies to prevent adolescent pregnancy, mainly among the poor population.

The ratio of admission by the unified health system category and that of vaginal delivery were higher among the adolescents. There were more adolescents without an economically active work. Thus, we recommend strategies to prevent adolescent pregnancy, mainly among the poor population.
