Bui HN, Schagen SEE, Klink DT, Delemarre-van de Waal H, Blankenstein MA, Heijboer AC. Salivary testosterone in female-to-male transgender adolescents during treatment with intra-muscular injectable testosterone esters. Steroids 2013; 78:91-5....
Post hoc analysis revealed that female-to-male transsexual persons with elevated levels of LH, indicating suboptimal testosterone therapy, reported significantly lower solitary sexual desire levels (than those with low LH levels; P=0.007). Suppressed LH levels were also associated with having a higher...
"It has been known for some time that higher testosterone is linked to smaller vocabulary in children and thatverbal fluencyskills decrease in female-to-male transsexuals aftertestosterone treatment. This fits in well with our finding of decreased grey matter volume. However, the strengthening of th...
In oviparous animals this can include prefertilization decisions such as the production of larger eggs and the deposition of hormones, such as the steroid testosterone, into yolks. On the other hand, a compensatory hypothesis posits that females allocate more resources into the eggs when mated ...
A nasal spray drug called bremelanotide is intended to stimulate nerve pathways linked to sexual arousal and has the same effect on men and women A drug named Intrinsa, developed by Procter & Gamble, is aimed at increasing female libido by boosting levels of the “male” hormone testosterone ...
Testosterone, FSH, trefoil factor 3 (TFF3), luteinizing hormone (LH), matrix metalloproteinase-3 (MMP-3), sex hormone-binding globulin (SHBG), leptin, age, human epidermal growth factor receptor 2 (HER-2) and ferritin were the ten most important variables for classification of sex and female...
To investigate the potential involvement of theca cells in the elevated testosterone levels of HFHS mice, we measured the thickness of the ovarian theca cell layers in antral follicles (Fig. 4C). We found that the thickness of the theca cell layer was significantly increased in HFHS mice ...
There’s a major hormonal difference between men and women that leads to a different result when training for strength and muscle. Men have much more testosterone that helps further build “man” muscles. Unless you’re taking up testosterone-boosting supplements, you’ll not grow as big as a...
Unlike some other female primates, women do not display obvious sexual swellings during the high-fertility phase of their ovulatory cycles. This simple observation has led some researchers to assume that women’s ovulatory status is completely concealed (Gangestad and Thornhill2008). By contrast with...
(Folstad & Karter,1992; Zahavi & Zahavi,1997), androgens responsible for enhanced secondary sexual characteristics are also immunosuppressive, which may lead to a greater vulnerability to pathogens. Males who possess “good genes” are able to withstand the immunosuppressive effects of testosterone and...
