Effects of prenatal stress on male offspring sexual maturity.
Prenatal stimulations have been shown to have long-term effects on at reproductive activity. We evaluated the influence of the prenatal stress on the hypothalamic-pituitary-gonad (HPG) axis in male offsprings from mothers with high number of offsprings per litter (HNL) and low number of offsprings per litter (LNL) after hypothesizing that the number of offsprings per litter may modify the effec...
متن کاملEffect of prenatal immobilization stress on sexual activity in male Wistar rats
Since the stress influences the biological processes, in the present study the effect of prenatal immobilization stress on the sexual activity of male rats was studied. Adult male and female Wistar rats (Pasteur Institute, Tehran) were copulated. After observing the vaginal plugs, pregnant rats were divided into control and two experimental groups. All groups were kept under the laboratory co...
متن کاملTestosterone is involved in mediating the effects of prenatal stress in male guinea pig offspring
Studies in humans have demonstrated a link between stress during pregnancy and altered behaviour and stress reactivity in children. In guinea pigs, we have previously shown that a short period of maternal stress during gestation leads to increased anxiety, elevated basal cortisol levels and decreased testosterone levels in adult males. We hypothesized that restoring testosterone to normal level...
متن کاملThe Effect of Prenatal Exposure to Restraint Stress on Hippocampal Granule Neurons of Adult Rat Offspring
Objective(s) It is well known that prenatal stresses (PS) induce a variety of neurobiological and behavioral alterations, some of them involving the hippocampal formation. This study aimed to determine whether restraint stress influences the neuronal volume and number of granule cells in the hippocampus of adult rat offspring. Materials and Methods Ten Wistar pregnant rats were randomly divi...
متن کاملDevelopmental effects of prenatal cocaine exposure on 5-HT1A receptors in male and female rat offspring.
Prenatal cocaine exposure results in behavioral abnormalities throughout development in rats, but little is known regarding the biological mechanisms underlying these abnormalities. Pregnant rats received subcutaneous twice-daily injections (1 ml/kg) of normal saline or 15 mg/kg of cocaine hydrochloride throughout gestation (gestation days 1-20). Following delivery, pups were placed with untrea...
