Mammalian external genitals show sexual dimorphism [1, 2] and can change size and shape upon sexual arousal. Genitals feature prominently in the oldest pieces of figural art [3] and phallic depictions of penises informed psychoanalytic thought about sexuality [4, 5]. Despite this longstanding interest, the neural representations of genitals are still poorly understood [6]. In somatosensory cort...
Mucosae of the female and male genital tracts are the portals of entry for sexually transmitted diseases (STDs) of viral, bacterial, and parasitic origin; worldwide, V120 000 000 cases of STDs are reported annually, but the true incidence is probably much higher. Infection with human immunode¢ciency virus (HIV) is no exception: epidemiologic data indicate that worldwide, 70^ 90% of all HIV infe...
Spermatophore formation in Galathea intermedia begins in the proximal part of the vas deferens. The contents subsequently form a spermatophoric ribbon, the so-called "secondary spermatophore," in its distal part. A strongly muscular ductus ejaculatorius is present in the coxa of the fifth pereiopod which builds up pressure for the extrusion of the spermatophoric ribbon. After extrusion, the rib...
BACKGROUND 46,XY disorders of sex development (46,XY DSD) are genetically heterogeneous conditions. Recently, a few submicroscopic genomic rearrangements have been reported as novel genetic causes of 46,XY DSD. METHODOLOGY/PRINCIPAL FINDINGS To clarify the role of cryptic rearrangements in the development of 46,XY DSD, we performed array-based comparative genomic hybridization analysis for 24...
The present study reviews the genus Agrotis Ochsenheimer, 1816 (Lepidoptera: Noctuidae: Noctuinae) in Iran from a taxonomic and faunistic point of view. An identification key of external features is presented for 16 Iranian species and subspecies. A description of each taxon is presented based on external male and female genital characteristics. Diagnostic features and comparisons with the clos...
With the evolution of social living came the problem of forming, maintaining, advertising, and repairing social bonds between individuals (e.g. de Waal 1986, 1993). Affiliative contact behaviors such as grooming and socio-sexual behavior play an important role in the expression and negotiation of social bonds. In rare cases an affiliative contact behavior may be restricted largely to one sex. P...
