RESUMO
The objective of this study was to evaluate the effect of the ethanol extract of Simarouba versicolor on reproductive parameters of Wistar rats (Rattus norvegicus): implantation index (%), resorption index (%), pre-implant loss, post-implant loss of the parents. pregnancy, the rats with approximately 90 days, weighing 160 to 250 g were divided into 4 groups (n=8), Control, Sv-EtOH 10, 20, 40mg/kg. The formulas used to evaluate reproductive parameters were following: IMPLEMENTATION INDEX = (number of implantations / number of corpus luteum)x100; REABSORPTION INDEX = (no resorption*/ no implants) x100* no resorptions = (no implants)-(nofetuses); PRE-IMPLANT LOSSES = (No. of corpus luteum - No. of implants / No. of corpus luteum) x100; POSTIMPLANT LOSSES = (number of implants - number of natives / number of implants) x100. In the analysis of the implantation index, resorption, pre-implant loss and post-implantation loss were not significant when compared to the control. These results indicate the absence of maternal toxicity for the investigated doses during the period of pre-implantation, implantation and full term pregnancy. However, further studies with different doses and concentrations of Simarouba versicolor extract will be necessary in the gestational period.

The aim of this study was to evaluate the reproductive organs on the effect of Simarouba versicolorethanol extract (EEOH-Sv) at a dose of 10mg / kg administered for 60 days / VO. The testes, epididymis,prostate and seminal vesicles were sectioned and placed in vials Boan solution for 24 hours and then preservedin alcohol at 70%. Histopathology of organs were dehydrated in xylol, impregnated and embedded in paraffin.Subsequently cut in the microtome at a thickness of 3 m and subjected to hematoxylin-eosin. The results of thehistopathology of the testis was observed that the EEOH-Sv caused concretions in 100% of animals evaluatedand 20% of the animals showed sharp associated with degeneration of the seminiferous tubules. In theepididymis was observed in 40% epithelial thickening, and there was 100% of benign prostatic hypertrophyassociated in 20% of animals inflammatory infiltrate. Thus, it is concluded that-Sv EEOH was toxic to thisorgans except the seminal vesicle.(AU)

Simarouba versicolor belongs to Simaroubaceae family. It is known that this and other species of thegenus have several activities including the antiestrogen and male infertility. In order to verify the ethanol extractof Simarouba versicolor (Sv-EtOH) in isolated uterus of Wistar rats, studies have been conducted with Sv-EtOHon the tonic contractions induced by KCl or oxytocin, recorded by isometric transducers coupled to a system ofdigital acquisition, by characterizing that blocking the uterine contraction induced by oxytocin, it was found thatthere was no significant inhibition of these contractions in the presence of Sv EtOH at concentrations of 500,750, 1000 µg / mL. The Sv-EtOH (81, 243, 500, 750, 1000µg/mL) did not induce a significant relaxation ofcontractions induced by KCl showing an EMAX 49.26 ± 7.32 and did not induce significantly the inducedrelaxation of concentrations with oxytocin EMAX de 18,78±4,91%.(AU)
