Background: Our aim was to evaluate the recovery rate of ovarian function and the activity of hypothalamus-hypophiseal- gonadal axis following transplantation of vitrified ovaries. Materials and Methods: Five weeks-old female Wistar Rats were distributed randomly in two experimental groups; Fresh Transplanted, Vitrified-Transplanted and 8 weeks-old female Wistar rats were considered as control ...

Sex differences in basal extracellular striatal dopamine concentrations in gonadectomized male and female rats have been reported previously. In the current experiment, estrous cycle-dependent variation, sex differences and the effect of gonadectomy on extracellular striatal dopamine concentrations were determined using quantitative microdialysis. Female rats were found to have significantly hi...

It has recently been reported from this laboratory that carcinoma of the adrenal cortex occurred in a high percentage of cases in extreme dilution strain ce mice that were gonadectomized at 2 days of age (3). The material collected from these animals is especially valuable because it gives a chance to study and detect the very early changes that precede and lead to the formation of rare tumors ...

The effects of chlorpromazine (CPZ) and estradiol benzoate (EB) on serum prolactin (PRL) levels were studied in gonadectomized male and female rats. In both sexes CPZ (25 mg/kg body weight) produced an elevation of PRL when measured 2 hr after the injection, but the elevated levels were higher in ovariectomized rats than in orchidectomized rats. These results reconfirm a sexual difference in th...
