background there is currently great concern about the possible adverse effect of microwave radiation from cell phones. in addition, noise is one of the physical pollutants of modern societies. objectives the present study aimed to examine the separate and simultaneous effects of cell phone microwaves, noise, and their effects on sperm parameters and total antioxidant capacity in adult male rats...

the purpose of this study was to evaluate the effect of dietary zinc levels during gestation on physical development of offspring. the statistical population consisted of adult male and female rats (albino-wistar) which were obtained from pasteur institute, iran. after mating, 9 pregnant female rats were divided into 3 groups: 1) zinc deficient group (0.05

Males are usually more prone to parasite infections due to behavioural and ecological patterns as well as genetic and physiological differences between males and females. They have associated aggression, dispersal, and assemblage, which increase the chances of contact with both ectoand endoparasites. In order to determine the effect of host sex on the establishment and development of Trichinell...

OBJECTIVE In this study we investigated the effects of spearmint (Mentha spicata Labiatae) on the reproductive system, fertility and number of offspring in adult male rats. MATERIALS AND METHODS Adult Wistar male rats in one control (C) and three experimental groups (I, II and III) received 0, 10, 20 and 40 mg/kg spearmint extract orally for 45 days, respectively. Following this treatment, th...

Rat urine contains many volatile constituents that may be used for chemical communication. The levels of certain urinary volatiles are strongly dependent on the sex and endocrine status (e.g., puberty). We performed chemical and behavioral studies to identify the volatiles in adult male rat urine that attract mature females. Our results demonstrated that adult male rats have higher levels of 2-...

Although various contraceptive methods and medications have been devised so far,there is no ideal male contraceptive agent,free from side effects and without adverse effects on secondary sexual  characterestics and sexual behaviour.in this study the antifertility effects of furazolidone on the process of spermatogenesis in adelt male rats have been evaluated.the results indicate that this drug ...

BACKGROUND Because of safety, repeatability, and portability, clinical echocardiography is well established as a standard for cardiac anatomy, cardiac function, and hemodynamics. Similarly, application of echocardiography in commonly used rat experimental models would be worthwhile. The use of noninvasive ultrasound imaging in the rat is a potential replacement for more invasive terminal techni...

Aim: investigate the implications of HFD induced obesity on lipid profile in parent rats and their offspring. Methodology: Twenty adult female (100 - 150g) were grouped into A B which received NRC respectively for 16 weeks. Group with BMI >0.50g/cm2 considered obese. Adult male Wistar fed introduced to each group, ensure mating pregnancy after feeding. The offspring produced by group...

Care of premature infants often requires parental and caregiver separation, particularly during hypoxic and hypothermic episodes. We have established a neonatal rat model of human prematurity involving maternal-neonatal separation and hypoxia with spontaneous hypothermia prevented by external heat. Adults previously exposed to these neonatal stressors show a sex difference in the insulin and gl...

  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...
