Facebook: A Próxima Arma na Luta contra as DST

 Salon (04.01.12)::Tracy Clark-Flory  
          
Investigadores de topo estão a estudar as formas de envolver o Facebook e outras redes sociais na prevenção de DST (doenças sexualmente transmissíveis).

Numa conferência recente, Peter Leone do Centro para Doenças Infecciosas da Universidade da Carolina do Norte discutia a forma como o círculo de amigos e parceiros sexuais pode ser um forte indicador de risco de DST. Citou o exemplo de um surto de sífilis na Carolina do Norte: "Quando examinámos as redes sociais conseguimos ligar muitos dos casos a encontros sexuais e quando perguntámos com quem se relacionavam estes indivíduos ou quem conheciam, conseguimos interligar 80 por cento dos casos."

 "As pessoas pensam que se tem de estar directamente conectado a alguém enquanto eu vejo as coisas a nível da população", afirma Leone. "Não é diferente de alguém que vai a um piquenique e apanha uma intoxicação alimentar. Preocupamo-nos com todos os que estiveram nesse piquenique."

De acordo com Sean Young, investigador no Departamento de Doenças Infecciosas da Universidade da Califórnia (UC) - Los Angeles, as redes sociais são, actualmente, um meio muito útil como portal de informação e fonte de discussão sobre risco e detecção. Esta normalização e destigmatização é exactamente o que pretende a campanha "Get yourself Tested" que apela aos mais jovens para que realizem o teste e utilizem a rede Foursquare no centro médico onde são acompanhados.

"Existem provas que (em termos de comportamento sexual) somos influenciados pelo que os nossos amigos fazem", afirma James Fowler, professor de genética médica na UC-San Diego e autor de " Connected: The Surprising Power of Our Social Networks and How They Shape Our Lives." Mas é preciso "contacto real e próximo para que as pessoas alterem o seu comportamento."

New Directions for Clinical Applications in Male and Female Sexual Dysfunction
 
The 5th Sexual Dysfunction Organising Committee would like to invite all General Practitioners, Sex Therapists, Psychologists, Psychiatrists, Counsellors, Physiotherapists, Urologists, Researchers and members of the broader medical community with a focus on Sexual Health to attend the 5th Sexual Dysfunction Conference 26th – 29th April 2012 in Queenstown New Zealand.

Located on the shores of Lake Wakatipu, Queenstown is one of the scenic icons of New Zealand with stunning views of the nearby Remarkable Mountains. Queenstown Airport is serviced by all major airlines and has regular national and international connections.
 
Queenstown is considered to be the adventure capital of New Zealand (some would say the world), with a wide range of activities including bungy jumping, rafting, skydiving, heliflights, heliskiing and many more thrilling activities. There is also a wide range of more passive activities such as cruises, walking, hiking, golf, fishing, farm visits, sightseeing and wine tours. Coronet Peak, The Remarkables, Cardrona and Treble Cone ski resorts are all close by. Nearby are a number of wineries producing some of New Zealand's best wines and Queenstown has excellent shopping for local products and a good selection of fine cafes and restaurants. Day tours depart from Queenstown for the world famous Milford and Doubtful Sounds in Fiordland or to Mount Cook, New Zealand's highest mountain (12,340 feet). Travel by coach, plane or helicopter for the scenic experience of a lifetime!
 
The meeting will be held at the Millenium Hotel which is located within minutes of the central shopping and entertainment area and just 20 minutes drive to the nearest skifield

Oxytocin involvement in SSRI-induced delayed ejaculation: a review of animal studies

Oxytocin involvement in SSRI-induced delayed ejaculation: a review of animal studies.

de Jong TR, Veening JG, Olivier B, Waldinger MD.
 
Abstract

INTRODUCTION: Selective serotonin reuptake inhibitors (SSRIs) differ in the severity of induced ejaculation delay. Various studies indicate that oxytocin is involved in sexual behavior.

AIM: To review and evaluate the involvement of oxytocin in SSRI-induced ejaculation delay.

MAIN OUTCOME MEASURES: Oxytocine release, 5-hydroxytryptamine (5-HT) neurotransmission, and desensitization of 5-HT(1A) receptors.

METHODS: A review and critical analysis of animal studies investigating the interaction of serotonergic and oxytocinergic neurotransmission in relation to the ejaculation process.

RESULTS: Although acute treatment with the SSRIs fluoxetine and paroxetine immediately causes increased serotonin levels, delayed ejaculation does not occur. The increased serotonin levels induce oxytocin release via activation of 5-HT(1A) receptors, and this might compensate for the inhibitory actions of serotonin on sexual behavior. Chronic treatment with fluoxetine and paroxetine desensitizes 5-HT(1A) receptors on oxytocin neurons, and that might in part determine the onset of delayed ejaculation. Desensitization of 5-HT(1A) receptors is less strong following chronic treatment with the SSRIs fluvoxamine or citalopram, which may attenuate the degree of delayed ejaculation.

CONCLUSIONS: Preliminary data suggest that the severity of chronic SSRI treatment-induced delayed ejaculation and the differences between the various SSRIs in inducing ejaculation delay is related to gradual desensitization of 5-HT(1A) receptors on oxytocin neurons.

Simultaneous penile-vaginal intercourse orgasm is associated with satisfaction (sexual, life, partnership, and mental health)

J Sex Med. 2011 Mar;8(3):734-41. doi: 10.1111/j.1743-6109.2010.02149.x. Epub 2010 Dec 8.

Abstract
INTRODUCTION: Previous multivariate research found that satisfaction was associated positively with frequency of specifically penile-vaginal intercourse (PVI; as opposed to other sexual activities) as well as with vaginal orgasm. The contribution to satisfaction of simultaneous orgasm produced by PVI merited direct examination in a large representative sample.

AIMS: To examine the associations of aspects of satisfaction (sexual, life, own mental health, partner relationship) with consistency of simultaneous orgasm produced by PVI (as well as with PVI frequency and vaginal orgasm consistency).

METHODS: A representative sample of Czechs (N = 1,570) aged 35-65 years completed a survey on aspects of satisfaction, PVI frequency, vaginal orgasm consistency, and consistency of simultaneous orgasm produced by PVI (the latter being a specially timed version of vaginal orgasm for women).

MAIN OUTCOME MEASURES: Analysis of variance of satisfaction components (LiSat scale items) from age and the sexual behaviors.

RESULTS: For both sexes, all aspects of satisfaction were associated with simultaneous PVI orgasm consistency and with PVI frequency (except female life satisfaction). All aspects of satisfaction were also associated with vaginal orgasm consistency. Multivariate analyses indicated that PVI frequency and simultaneous orgasm consistency make independent contributions to the aspects of satisfaction for both sexes.

CONCLUSIONS: For both sexes, PVI frequency and simultaneous orgasm produced by PVI (as well as vaginal orgasm for women) are associated with greater life, sexual, partnership, and mental health satisfaction. Greater support for these specific aspects of sexual activity is warranted.

Abstract

INTRODUCTION: Evidence was recently provided for vaginal orgasm, orgasm triggered purely by penile-vaginal intercourse (PVI), being associated with better psychological functioning. Common sex education and sexual medicine approaches might undermine vaginal orgasm benefits.

AIMS: To examine the extent to which women's vaginal orgasm consistency is associated with (i) being told in childhood or adolescence that the vagina was the important zone for inducing female orgasm; (ii) how well they focus mentally on vaginal sensations during PVI; (iii) greater PVI duration; and (iv) preference for above-average penis length.

METHODS:   In a representative sample of the Czech population, 1,000 women reported their vaginal orgasm consistency (from never to almost every time; only 21.9% never had a vaginal orgasm), estimates of their typical foreplay and PVI durations, what they were told in childhood and adolescence was the important zone for inducing female orgasm, their degree of focus on vaginal sensations during PVI, and whether they were more likely to orgasm with a longer than average penis.

MAIN OUTCOME MEASURES: The association of vaginal orgasm consistency with the predictors noted above.

RESULTS: Vaginal orgasm consistency was associated with all hypothesized correlates. Multivariate analysis indicated the most important predictors were being educated that the vagina is important for female orgasm, being mentally focused on vaginal sensations during PVI, and in some analyses duration of PVI (but not foreplay) and preferring a longer than average penis.

CONCLUSIONS: Focusing attention on penile-vaginal sensation supports vaginal orgasm and the myriad benefits thereof. Brody S, and Weiss P. Vaginal orgasm is associated with vaginal (not clitoral) sex education, focusing mental attention on vaginal sensations, intercourse duration, and a preference for a longer penis.
