PURPOSE: to evaluate the effects of the administration of two synthetic steroids in the uterus morphology and in the reproductive parameters of adult female rats. METHODS: divided into four experimental groups: control (C; physiological solution); treated with nandrolone decanoate (DN; 7.5 mg/kg of body weight); with a testosterone esters compound (T; 7.5 mg/kg); and simultaneously with DN and T (7.5 mg/kg of each steroid), in a single intraperitoneal weekly dose, for eight weeks. Five females of each group were sacrificed and the uterine horns were collected, weighted and prepared for histological and morphometrical evaluation. The remaining rats were mated with normal male rats for reproductive parameters evaluation, composing the groups treated during the pre-gestational period. Another group of 20 female rats were treated during the gestational period (7th-14th days). For data analysis, the Kruskal-Wallis non-parametric variance analysis was used, followed by the test of Dunn or of Student-Newman-Keus (5% significance level). RESULTS: there was a significant body weight increase in the androgenized females (ND: 305±50; T: 280±35; ND+T: 275±30 versus C: 255±22 g; p<0.05). Uterine weight was not affected by the steroidal treatment (ND: 0.6±0.2; T: 0.4±0.04; ND+T: 0.7±0.1 versus C: 0.4±0.09 g). All the androgenized females presented estral acyclicity and endometrium characterized by papilliferous luminal lining, oedematous stroma with hemorrhagic areas and secretory activity. There were changes in the morphometrical thickness parameters of the luminal epithelium, myometrium and perimetrium in the androgenized groups. None of the female rats got pregnant when treated with steroids in the pre-gestational period and the treatment during organogenesis affected negatively the reproductive parameters. CONCLUSIONS: steroidal agents alter the uterine structure and impair fertility and gestational outcome in female rats.

PURPOSE: to compare in a retrospective way, 51 women who underwent tubal ligation, 30 through microlaparoascopy (Gmicrol) and 21 through minilaparotomy (Gminil). METHODS: the analyzed parameters were: total time for accomplishment of the procedure and the surgical technique, time of hospital stay and return to the habitual activities after the surgery, postoperative pain, morbidity, satisfaction degree and esthetic effect, considering values of p<0,05 as significant, and also standard cost. RESULTS: Gmicrol took less time to accomplish the surgery than the Gminil (43 against 57 minutes respectively, p<0,05), less time to accomplish the surgical technique (6.48 against 30.32 minutes respectively, p<0,05), and lower hospital stay (9,90 hours as against 41,7 hours respectively, p <0,05). There was no significant difference between the two groups regarding time to return to the habitual activities after surgery. To evaluate postoperative pain, a scale of 0-10 it was applied. Gmicrol present a lower pain score on the 1st and 2nd postoperative days (1.13 and 0.26 to Gmicrol and 4.52 and 1.14 to Gminil, respectively, p<0,05). There was no significant difference between immediate postoperative the most common complaint being pain at the site of pain and that on the 3rd postoperative day. Gminil presented a higher morbidity rate incision. To evaluate the satisfaction degree and esthetic effect, numeric values were attributed to as good, regular, poor and very bad as answered by the patiets. Gmicrol presented a higher satisfaction degree (p<0,05) and better esthetic effect as compared to Gminil (p <0,05). The microlaparoscopy standard cost was R$ 109.30 being lower than that of minilaparotomy. CONCLUSIONS: tubal ligation by microlaparoscopy, under local anesthesia and conscious sedation presented some advantages compared to minilaparotomy.
