The present study is the first to demonstrate that sex differences in hypothalamic activation upon smelling the chemo-signal androstadienone are not acquired during sexual maturation, under the influence of gonadal hormones during puberty, but might be considered hard-wired responses, which already can...
During puberty gonadotropin releasing hormone sets off a cascade of other hormones: a) the typical cascade for the female and what secondary sexual characteristics occur as a result. b) the typical cascade for the male and what secondary sexual characte ...
Certainly, the hormones involved in puberty may have a role in influencing gender identity. Studies conducted on people with 5 alpha-reductase deficiencies showed that about 50% of these patients changed gender identity during puberty [51]. On the contrary, in pathologies affecting the sex chromosom...
These influences also appear to play an important role in functional and structural brain development during adolescence. Finally, we offer some thoughts on directions for future research in these areas. 展开 关键词: behavior puberty social-affective development testosterone ...

Leptin was also found to stimulate gonadotropin hormone expression, as well as act as a puberty permissive factor under the influence of steroid hormones [29]. It was further reported to affect ovarian function, linking follicular alterations with obesity [30]. Additionally, a significant role of ...

Beyond genetic variation, other proposed mechanisms feature a role for sex steroid hormones during neurodevelopment. The best known is the extreme male brain (EMB) theory, which was proposed by Simon Baron-Cohen and conceptualizes the cognitive-behavioral phenotype of ASD as an amplification of male...
