| The reproductive system of male Phrynops geoffroanus adults is macroscopically described and the variation in testicular biometry is evaluated. A pair of oval testes is connected by the efferent ductules to the epididymis, which continue as deferent ducts, which emerge in the penis. The volume of the gonads showed the highest averages during spring and summer months. GSI varied significantly throughout the year, with the highest averages observed in the months that correspond to the end of spring and the beginning of summer, when the reproduction of the species takes place, and the lowest averages were seen in winter, suggesting a cyclical testicular activity. |

| Caesalpinia ferrea Mart (Leguminosae) is a medicinal plant used to treat diabetes, among other therapeutic properties, but which is also reported to have hepatotoxic effects. Although it contains substances such as flavonoids and coumarin, which are known to have antifertility activity, no studies have apparently been conducted to evaluate the potential adverse side effects of this plant on the function of the reproductive system after a chronic treatment. Therefore, this investigation was carried out to evaluate the effect and safety of the long-term exposure to C. ferrea on male Wistar rats' vital organs, reproductive system and sperm production. Adult and immature male rats were treated with an aqueous extract of C. ferrea at a dose level of 300 mg/kg... |

| Studies of developmental effects of mixtures of endocrine disrupters on the male reproductive system are of great concern. In this study, the reproductive effects of the co-administration of di-2-(ethylhexyl) phthalate (DEHP) and genistein (GEN) during pregnancy and lactation were studied in male rat offspring. Pregnant Sprague-Dawley rats were gavaged from gestation day 3 to postnatal day 21 with vehicle control, DEHP 250 mg/kg body weight (bwyday, GEN 50 mg/kg bwday, GEN 400 mg/kg bwday, and two combinations of the two compounds (DEHP 250 mg/kg bwday + GEN 50 mg/kg bwday, DEHP 250 mg/kg bwday + GEN 400 mg/kg bwday). The outcomes studied were general morphometry (weight, AGD), testicular histology, testosterone levels, and expression at the mRNA level of... |
