Determinism sexual behavior

Determinism sexual behavior

Behavior is defined as a set of complex reactions of the organism to internal and external stimuli, motivated and organized responses by innate reflexes and won, which directs integration point to certain environmental conditions (Scripcaru 1987).
Sexual behavior is determined by biological factors aside (genetic and hormonal) and on the other the educational, ethnic and social.

Determinism anatomical structures involved in sexual behavior are:
- Hypothalamus that governs the production of sex hormones but is also directly involved in some reactions dynamic behavior.
- Medial preoptic area is responsible for stimulating sexual behavior, especially in men. At this level there is a sexually dimorphic nucleus role in the control of pituitary function and autonomic system but also in information integration. Seems to control especially consumer phase of sexual behavior and less on the initiation (V.Mogos & E.Zbranca).
- Ventro medial nucleus appears to be involved in managing female sexual behavior.
- Mamilari corpora are involved in the sexual behavior of both sexes.
- The limbic system intervenes in the genesis of sexual satisfaction
Temporal lobe appears to be involved in sexual behavior as well as the front.
 Determinism sexual behavior
Sexual dimorphism, sexual dimorphic structures and functions underlying sexual behavior.

Sexually dimorphic structures are:
1. Sexual differentiation is the first genetic sex of the individual and the zygote stage is represented by the formula chromosome.
2. sex gonads (sexual glands) is by definition dimofic and develop genetic condition.
3. gonoforic sex (genitalia). External genitalia differentiate under the influence of gonadal hormones.
4. sexual dimorphism of the central nervous system and the hypothalamus.

Sexually dimorphic functions are:
1. Individual's gender identity-consciousness that belongs to one or other sex.
2. Sexual role-everything that makes a person face to reveal himself and by others as belonging to one sex or the other.
3. Aggressive behavior more strongly expressed in males.

Sex hormones play a vital role in sexual behavior since determinism by stimulating differentiation of target tissues during intrauterine life (starting with the fourth pregnancy) and continuing until pupertate.

Of course, in shaping educational intervention component of adult sexual behavior is not negligible ..

Development of sexual behavior intrauterine life begins so when, under the influence of gonadal hormones, stabilizes the secretion pattern of LH-RH hypothalamic level (continuous type is the type cyclic man and the woman). This phenomenon occurs in IV-VI months of pregnancy. Subsequently, VII-IX months will be organized sexual behavior differently for the two sexes.

Of prenatal androgen excess can cause ambiguous genitalia in girls with different degrees of severity, up to complete masculinization of the external genitalia, heterosexual orientation is still in most cases. Equally androgen deficit in the same period in male subjects will cause genital ambiguity.

Recent studies have demonstrated that exposure showed both estrogen and androgen excess in life ectopic expression would facilitate more frequent gay and / or bisexuality.

During childhood, around the age of 2-4 years to develop gender identity under the influence of ambient stimuli - parental behavior, identity, civil, etc..

Under the action of sex hormones at puberty develop secondary sexual characters and the neuropsychological which enable the individual to comply with requirements imposed by adult life. Thus, genitalia will develop morphologically but also in terms of excitability and the behavioral plan facitileaza erotic expression and sexual behavior. Boys increased initially nocturnal testosterone level will be reflected in the development of nocturnal emissions and then in the initiation and maintenance of masturbation.

Eroticism manifested in puberty shows differences from one sex to another. In boys imagination itself predicts sexual behavior and excitability is dominated by visual stimuli while the girls, your imagination is meager and excitability is dominated by tactile stimuli and past experiences. In boys, libido and sexual function and correlates with androgen levels in girls with interaction with other girls around them who have this experience.

Adult male sexual behavior is maintained by stimulating androgen trophicity genitals as well as by initiating and sustaining desire and sexual dynamics. The diurnal and nocturnal erections are dependent on Testosterone spontaneous but induced the erotic stimuli are (Bancroft 1989) therefore exhibit sexual behavior relative independence from hormonal stimuli.

In women, sexual behavior is activated by gonadal hormones but rather experiencing orgasm is conditioned by social context and relational experience than the level of sex hormones.

The elderly due to decreased hormone secretion vaginal lubrication problems arise from steps that can develop fear of penetration and loss of sexual desire. Lubrication problems are solved by estrogen administration.

Elderly man slowly to reduce the quality of erections and ejaculations. During genital stimulation needed to achieve an erection grows. If these changes occur amid plans to keep sexual desire mental effects can be very unpleasant.

Regarding homosexual behavior it seems that circulating sex hormone levels were normal but there is a possibility that the answer hypothalamic-pituitary-gonadal chain to be lower hormonal stimuli or their metabolism in the brain to be changed.

Long to the idea that homosexuality appearance as heterosexual sexual experiences related to early childhood trauma and sexual reorientation tempted away from the subject. This is an attempt doomed to failure because homosexuality is irreversible established.

Unlike homosexuality is a disturbance of orientation exuale, transexualismul is a deep gender identity disorder (the subject is convinced that belongs to the other sex, contrary to his physical constitution). Of all pathogenic theories developed in an attempt to explain the occurrence transexualismului the hormone seems to be the strongest. This supports the existence of a hormone deficiency since the womb which would lead to a failure of the primary organization of sexual behavior.
However, transexualitatea as homosexualitetea is irreversible, so any attempts to convince the subject to accept their biological sex is doomed to failure and therefore useless.
