Fertility of male adult rats submitted to forced swimming stress
(Associação Brasileira de Divulgação Científica (ABRADIC), 2003-05-01)
We investigated whether stress interferes with fertility during adulthood. Male Wistar rats (weighing 220 g in the beginning of the experiment) were forced to swim for 3 min in water at 32ºC daily for 15 days. Stress was ...
Does the male reproductive performance depend on the early lactation milk in rats?
(1996-01-01)
This study investigated the role of the early lactation milk (ELM) on the male reproductive performance and the participation of GnRH on this effect in Wistar rats. Newborn males were divided into three experimental groups: ...
Sexual behavior and fertility of male rats submitted to prolonged immobilization-induced stress
(Associação Brasileira de Divulgação Científica (ABRADIC), 2000-09-01)
In order to investigate whether prolonged stress interferes with the onset of sexual behavior at puberty and with fertility at adulthood, prepubertal male Wistar rats (40 days of age) were immobilized 6 h a day for 15 days ...
Copulatory efficiency and fertility in male rats exposed perinatally to flutamide
(Pergamon-Elsevier B.V. Ltd, 2011-01-01)
This study investigated the effects of perinatal treatment with flutamide on male sexual behavior, semen parameters, and fertility in adult male rats. Pregnant rats received 15 mg/kg of flutamide or peanut oil, s.c., at ...
Sexually dimorphic traits and male fertility in a paper wasp
(Oxford Univ Press, 2020-07-01)
Females of many social Hymenoptera commit their reproductive potential to a single male; they mate once and never re-mate. Sexual selection theory predicts that under this regimen female precopulatory mate choice is crucial. ...
Reproductive changes in male rats treated perinatally with an aromatase inhibitor.
(2002-01-01)
The effects of maternal exposure to aromatase inhibitor during the perinatal period of sexual brain differentiation were studied. The fertility was assessed in adult, male rat offspring of aromatase inhibitor-treated dams. ...
Effects of prenatal hydrocortisone acetate exposure on fertility and sexual behavior in male rats
(Elsevier B.V., 2003-08-01)
The aim of the present study was to investigate the effects of hydrocortisone during the prenatal period and its later repercussions on the fertility and sexual behavior of male rats. Pregnant rats were treated (s.c.) with ...
Neonatal inhalatory anesthetic exposure: Reproductive changes in male rats
(2002-12-01)
We investigated the effects of an inhalatory anesthetic (ethyl ether) during the neonatal period of brain sexual differentiation on the later fertility and sexual behavior of male rats. Animals were exposed to ethyl ether ...
