Sexual behavior reduced

The YRBSS has much more information than what is reported here. These questions would be the most likely to be directly or indirectly related to drug use. Although some of these issues have moved in a positive direction, others have not. Sexual behaviors reduced somewhat and violence-related behaviors generally increased. Achievement of the 2007 goal is possible only in regard to suicide planning. However, suicide attempts have increased in the time frame reported. 

Second, sexual behavior might change if the good message of a treatment of HIV/AIDS spreads. Already today we have an increase of incidence in some countries, such as Germany. This might be partly due to the long-term consequence of a reduced horror. ...

Wysocki, 1989) reduces ultrasonic vocalizations by male mice when a female is present (Wysocki etal., 1982) and abolishes maternal aggression in primiparous female mice (Lepri etal., 1985). Deafferentiation of the VNO in male mice impairs sexual behavior. The effect is greatest if the male was deafferentiated before experience with any adult female (Clancy etal., 1984). Aggressive behavior in male mice is less reduced after deafferentiation of the VNO if they had had fighting experience (Daranzoet a /., 1983). 

Although reduced sleep is often an early prodromal symptom, patients are usually brought for evaluation and treatment when their behaviors create the potential for more severe consequences (e.g., self-injurious behavior, atypical sexual behavior, significant financial indiscretions). 

Reports of the effects of amfetamine on sexual behavior refer variously to unchanged, reduced, mixed, and heightened sexual performance, but long-term abusers often have sexual dysfunction (SED-9, 9). 

To observe the role of chemical cues in the sexual behavior of males of small mammals, we can alter the odor of females. Hair is a great substrate for odor-carrying lipids. For example, the behaviorally active body odors of sheep reside in the wool fat, also known as suint. Removing hpids from the fur of female mice reduces the lipophilic odorants significantly. Hair near skin glands is often anatomically modified into osmetrichia to hold sebum on its cuticular surface (Miiller-Schwarze et al. 1977). 

After leaving their mother, young female pandas are thought to wander some distance to find a territory in a different area. This behavior reduces inbreeding in panda populations. Pandas become sexually mature at 6-7 years of age, and probably live to about age 15 in the wild. The small number of young produced per female per year, plus the relatively late age of sexual maturity, means that population growth rates are low. This makes giant panda populations vulnerable to extinction if the rate of mortality increases. 

Fish made anosmic by occlusion of the nares, cautery of the nasal epithelium, or section of the olfactory tracts showed reduced sexual behavior or ability to discriminate pheromone-bearing water (Tavolga,... 

When a courtship response is used as an indicator of pheromone sensitivity, the failure of immature animals to respond may be a reflection of a reduced state of sexual motivation rather than an inability to detect pheromonal odors. In a wide variety of male and female teleosts, sufficient levels of circulating sex steroids are required before sexual behavior is expressed (Liley and Stacey, 1983). The sex steroid concentrating areas of the ventral telencephalon and preoptic area are thought to mediate this effect by controlling behavioral output, a function distinct from their possible role in the detection of pheromones per se (see discussions in Kyle and Peter, 1982 Kyle et al., 1982 Demski and Hornby, 1982).
