Abnormal semen analysis results could mean you have a physical problem in your reproductive tract, or that your body isn't making enough testosterone. However, test results aren’t always a true indicator of fertility. For example, you could have a low sperm count and still be fertile, or h...
Moreover, under androgen deprivation, the carrying capacity of cancer cells dependent on testosterone was made a linear function of the density of the testosterone producing cancer cells. As such, the originally noncooperative game between the three cancer cell types includes also cooperative elements....
Thus, testosterone deficiency may induce the sperm miRNA alterations by exosomes in seminal plasma, which are further responsible for the decline of sperm motility[59] (Figure 1). Effects of Other Sources of EVs on Male Reproduction In addition, other tissues or cells in the body can secrete...

The effects of gonadal hormones on suicide-related endophe- notypes may be integrated with those of 5-HT dysregulation, discussed above, as testosterone increases 5-HT transporter mRNA expression and binding in rats and humans.207,208 In addition, testosterone increases the neuronal firing rates ...
stages, but did significantly increase at the time when a males’ partner is about to become fertile again (as one set of offspring are about to fledge. The higher level of testosterone makes sense, because we demonstrated that higher testosterone is related to the swimming performance of sperm...

Testosterone treatment of orchiectomized male rats has no effect on nitric oxide levels or nitric oxide mediated dilation in cerebral vessels [25]. Notably, estrogen acts through a number of mechanisms to maintain cerebral autoregulation [24] to partially restore myogenic tone in ovariectomized ...
PCOS blood tests include follicle-stimulating hormone (FSH), progesterone, testosterone, and prolactin. These tests cannot confirm a PCOS diagnosis on their own. An ultrasound showing multiple ovarian cysts is the main diagnostic feature of PCOS. ...
