Sexual behavior humans

These cues are important in rearing, territorial, courtship and, in particular, sexual behaviors. The vomeronasal organ (VNO) is separate from the main epithelium in mammals, comprising a thin epithelial tissue within a bony capsule in the lateral wall of the nasal cavity. It is probably vestigial in humans. The VNO epithelium contains at least two populations of microvillar chemosensory neurons one is in the more apical aspects of the epithelium, while the other lies in the more basal region. These two populations of vomeronasal neurons (VNs) are defined by the differential expression of several genes. For example, the apical VNs express the G-protein subunit Ga, while the basal neurons express Ga0. Apical and basal VNs also... [Pg.824]

Removal of the adrenal gland, and thus adrenal androgens, has been associated with an inhibition of sexual behavior in both humans and primates. In addition, in primates exogenous androgens, but not estrogens, reportedly reversed the effects of adrenalectomy. Exogenous androgen treatments reportedly can facilitate sexual responses in women (Sherwin, 1996). [Pg.147]

Phthalates are suspected of acting as endocrine disrupters also in humans, affecting male and female reproductive tract development. Exposure to PAEs in adult men has been associated with semen quality and alterations in sexual behavior [104], and with endometriosis and intrauterine inflammation (which is a risk factor for prematurity) in adult women [105, 106], as well as other effects. These studies suggest that DEHP may play a role in inducing the intrauterine inflammatory process. Besides the reproductive effects of PAEs, recent studies have also shown the genotoxicity of DEHP, DBP, and DiBP in human lymphocytes and mucosal cells [107,108]. [Pg.318]

All prescription drug abuse may lead to harmful consequences such as accidents, injuries, blackouts, legal problems, and unsafe sexual behavior, which can increase the risk of acquiring sexually transmitted diseases (STDs) and human immunodeficiency virus (HIV). Specifically, each class of drugs has certain potentially life-threatening consequences of abuse. The abuse of opioids may lead to severe respiratory depression and inability to breathe, which can lead to death. Depressants may also cause respiratory depression and may lead to seizures if an addict suddenly stops taking them. Stimulants speed up the body s activities and raise blood pressure and heart rate, and when abused, may lead to a heart attack, stroke, or a seizure. Combinations... [Pg.18]

Lifestyle (environmental) factors including smoking, diet, cultural and sexual behavior, occupation, natural and medical radiation, as well as exposure to substances in air, water, and soil all influence the carcinogenic process in humans. Cancer susceptibility is determined by complex interactions between age, environment, and an individual s genetic make-up. [Pg.538]

Olfaction plays an important role in sexual behavior in many animals. Macrosomatic animals have a highly developed ability to use olfaction for identifying sexual partners, enemies and food i.e.. these animals use olfaction for survival and continuation of the species. The linkage between reproductive behavior and olfaction is not as strong in humans but we may still possess the neural hardware tying odors to sexual arousal and certainly the profit and loss statements of the fragrance industry attests to a key role of olfaction in human sex drives. [Pg.539]
