Sexual function was examined in spontaneously hypertensive rats (SHR) from 8 to 20 wk of age and compared with normotensive Wistar-Kyoto (WKY) and Long-Evans rats (LE). Blood pressures (evaluated indirectly) were elevated in SHR (185 +/- 2 and 195 +/- 3 mmHg at 16 and 19 wk of age...
Sexual differentiation of the brain is a function of various processes that prepare the organism for successful reproduction in adulthood. Release of gonadal steroids during both the perinatal and the pubertal stages of development organizes many sex differences, producing changes in brain excitability and...
Current evidence indicates that sexual differentiation of the human brain occurs during fetal and neonatal development and programs our gender identity-our feeling of being male or female and our sexual orientation as hetero-, homo-, or bisexual. This sexual differentiation process is accompanied by ...
In recent years, more and more emphasis has been placed on the investigation of sex differences in the human brain. Noninvasive neuroimaging techniques represent an essential tool in the effort to better understand the effects of sex on both brain structure and function. In this review, we provi...
Recent findings, however, suggest that brain cells that differ in their genetic sex are not equivalent, and that difference may contribute to sex differences in brain function. Here we discuss evidence for sex chromosome effects on both neural and nonneural systems, which together provide support ...
Sexual dimorphism in body and brain weight was studied in cats. Paw preference was assessed by food reaching test. Sexual dimorphism in body weight related to paw preference. Males weighed more than females in total sample and non-right-handed (NRH) cats (no significant difference in right-hand...
Moreover, concepts referring to "male brain", "female brain" or "sexual dimorphism" are outdate and incorrect, and therefore should be avoided in the neuroscientific literature. Finally, neuroscientists with a focus on sex/gender difference should adopt a psychobiosocial approach whenever possible, ...

The human sexual response is a complicated biopsychosocial phenomenon in which internal and external stimuli are modulated by the central and peripheral nervous system, resulting in a cascade of biochemical, hormonal and circulatory changes that lead to cognitive and physical sexual arousal. In this art...
