The Effect of Testosterone Propionate on the Sex-life of the Female Rat
نویسنده
چکیده
THE action of hormonic substances on the smaller experimental animals is usually assessed by killing the animal and examining its organs shortly after treatment. The present paper deals with a study of the effects of testosterone propionate injections on the subsequent life of the female rat. An earlier paper (Groome, 1939, which see for references) describes the immediate anatomical effects of testosterone propionate on the young female rat. In this instance the experiment was repeated, but instead of killing the females, when the course of injections was completed, males were introduced and the sexual cycle observed.

the previous studies have been suggested that to tolerance,sensitivity and pain threshold are different between men and women.these differences can be affected by various factors.in this study,the effect of gonadectomy on gender differences in thermal pain sense threshold was tested hot plate method in rats.therefore the reaction time(the delay occurred in response to thermal stimulus)at zero,1...
متن کاملOrganizational effects of testosterone, estradiol, and dihydrotestosterone on vasopressin mRNA expression in the bed nucleus of the stria terminalis.
In adulthood, male rats express higher levels of arginine vasopressin (AVP) mRNA in the bed nucleus of the stria terminalis (BST) than do female rats. We tested whether this sex difference is primarily due to differences in neonatal levels of testosterone. Male and female rats were gonadectomized on the day of birth and treated with testosterone propionate (TP) or vehicle on postnatal days 1, 3...
متن کاملRelationship between neonatal testosterone and 5-hydroxytryptamine (5 HT) in controlling the pattern of LH release in adult rats
Relationship between neonatal testosterone and 5-hydroxytryptamine (5-HT) in controlling the pattern of LH release in adult rats was investigated in this study. Hypothalamic 5-HT concentrations are transiently lower in male as compared to female Wistar rats in the second week post-partum (pp). It has also been shown that pharmacologically potentiating 5-HT activity during this period feminizes ...
