TestosteroneCortisolCold-pressor testHeart rate variabilityBlood pressureHigher testosterone levels in males have previously been linked to decreased stress reactivity, but in other cases, testosterone has been reported to increase the stress response. We addressed these inconsistencies in a placebo-...
plasma ET-1 content in Cas was significantly higher(P0.05),and no significant change in TC group(P 0.05).Compared with Cas group,plasma testosterone and NO concentrations were significantly increased;whereas plasma ET-1 level was reduced in TC group(P0.05).Conclusion Change of testosterone levels...
The hormone also affects your state of mind, including how well your brain works. Low testosterone has been linked to mood swings, increased stress, and depression. “Cells in the brain have testosterone receptors, and low testosterone in those receptors significantly affects mental health.” Muscle...
Although DNA per well was significantly higher ( P 0.1) effect on DNA concentration in either cell type. Overall, cells from small follicles incorporated significantly ( P < 0.01) more [ 3 H]-thymidine than those from medium follicles. Both oestradiol and testosterone significantly ( P < 0.01...
The participants having received testosterone showed a more reactive fear pattern, with higher peaks and steeper reductions in fear levels in session 2. Post-hoc exploration of moderating effects of endogenous testosterone levels, revealed that this pattern was specific for women with high basal ...
Repeated measures ANCOVA on the 96 participants confirmed a significantly higher testosterone level after hormone application in the testosterone group compared to the placebo group. Following a non-significant difference in testosterone levels at baseline (Time 1, p = 0.81), hormonal levels differe...
We examined the effects of physiologic testosterone therapy added to standard estrogen/progestin therapy on quality of life, self-esteem, and mood in women with POI. METHODS: One hundred twenty-eight women with 46,XX spontaneous POI participated in a 12-month randomized, placebo-controlled, ...
Magnetic resonance imaging (MRI) studies of individuals with X-variant sSCA (sSCA X ) tend to reveal lower total brain volumes (TBV) and higher ventricular volumes [12]-[14]. Diffusion tensor imaging studies have also reported lower fractional anisotropy in 47,XXY [15]. People with Y-variant...
erythroid 2-related factor 2-antioxidant response element (Nrf2-ARE) pathway regulates cellular responses to oxidative and electrophilic stress. In the aging process, the circulating level of testosterone was progressive reduction in males15,16. Androgen was capable of modulating two important cellular ...
While many samples were mixed or consisted of women, only two studies exclusively recruited males. In view of the hormonal differences (i.e. the higher testosterone levels in men), it can be assumed that particularly strength gains will be different depending on the sex of the participants46....
