Effects of administering testosterone undecanoate in rats subjected to physical exercise: effects on the estrous cycle, motor behavior and morphology of the liver and kidney

The aim of the work was evaluate the effects of testosterone undecanoate (TU) treatment combined with moderate physical training on: the estrous cycle, body weight (BW), motor behavior (MB), and the morphohistology of the reproductive system, the liver and kidney in rats. Female Wistar rats (180 g -...

Female Wistar rats (180 g - 250 g) were divided as follows: sedentary + TU (S + TU), trained + TU (T + TU), sedentary + vehicle (S + V), trained + vehicle (T + V). The rats swam 50 min/Day, strapped with a 5% BW load, for 4 weeks. During this training, (BW) was monitored daily as well as the estrous cycle (EC) by vaginal smear. The TU (15 mg/kg s.c) was administered 3 times/week for 4 weeks. At the end of the study, data on MB, BW and morphohistopathological changes in viscera were compiled. The (T + TU) group had on average, a higher (BW) in the fourth week compared to the first week, and (BW) higher than (S + V) and (S + TU) groups. We noted an interruption in the EC and a decrease in weight of ovaries in animals treated with TU. In addition, there was an increase in the relative weight of the heart in groups (T + V) and (T+ TU), and kidneys in group (T + TU). Histopathological analysis showed periportal congestion and isolated foci of hepatic necrosis in rats with TU. Thus, TU combined with training abolished the EC, promoted ovarian atrophy, liver necrosis, cardiac hypertrophy and a decrease in motor activity.<br>O objetivo do trabalho foi avaliar o efeito do tratamento com undecanoato de testosterona (UT) combinado ao treinamento físico moderado sobre ciclo estral, peso corporal, estruturas do sistema reprodutor, comportamento motor e morfologia hepática e renal em ratas. Ratas Wistar (180 a 250 g) foram divididas em: sedentárias + UT (S+UT), treinadas + UT (T+UT), sedentárias + veículo (S+V), treinadas + veículo (T+V). As ratas nadaram 50 min/dia com sobrecarga de ~5% do peso corporal por 4 semanas. Durante o período de treinamento foi realizado acompanhamento diário do peso corporal (PC) e do ciclo estral (CE) pelo esfregaço vaginal. O UT (15 mg/kg s.c.) foi administrado 3x/semana durante 4 semanas. Ao final foram avaliados comportamento motor, pesos e alterações histopatológicas de alguns órgãos. O grupo T+UT apresentou PC maior na quarta semana do que na primeira, com pesos corporais maiores que os grupos S+V e S+UT. Houve interrupção no CE e redução do peso dos ovários nos animais tratados com UT. Houve aumento do peso relativo do coração, nos grupos T+V e T+UT, e do peso relativo dos rins, no grupo T+UT. A análise histopatológica revelou congestão periportal e focos isolados de necrose hepática nas ratas com UT. O UT combinado com treinamento produziu supressão do ciclo estral, atrofia ovariana, necrose hepática, hipertrofia cardíaca e redução da atividade motora.http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1984-82502010000100009Esteróides androgênicos anabólicosExercício físicoUndecanoato de testosteronaAndrogenic anabolic steroidsEndurance trainingTestosterone undecanoate
