Researchers have demonstrated a range of factors that are associated with adolescents who engage in problematic or harmful sexual behaviour (HSB) including adverse childhood experiences, disruptive family organisation, poor attachment or attachment style deficits, social isolation, and substance abuse. There is, however, a paucity of research examining sexual development histories in adolescent males who have engaged in HSB. This study describes the sexual developmental histories that precede such behaviour, of 277 adolescent males who were referred for assessment of HSB in New Zealand (NZ). It informs the realities of practice and directs us to the need for research examining the patterns of early sexual development so as to identify possible risk factors and pathways for concerning sexual behaviour.

Background Sexual offending has been attributed to empathy deficits, implicating interventions targeting empathy as a potential mechanism for reducing sexually harmful behaviour. However, there is less known about how appropriate and effective interventions are for individuals with intellectual disabilities. This review aims to provide a comprehensive synthesis of research findings in this area.

There is an increasing adolescent population with severe obesity with impairments in social and romantic relationships that are seeking clinical weight management, including weight loss surgery (WLS).
To document romantic, sexual and sexual risk behaviours in a clinical sample of adolescent females with severe obesity (BMI? > ?40?kg/m 2 ) compared to those of healthy weight (HW).
This multi‐site study—an ancillary to a prospective longitudinal observational study documenting health in adolescents having WLS—presents pre‐operative/baseline data from 108 females undergoing WLS, 68 severely obese seeking lifestyle intervention and 118 of HW. Romantic and sexual risk behaviour and birth control information sources were assessed using the Sexual Activities and Attitudes Questionnaire (SAAQ).
Severely obese females reported engaging in fewer romantic and sexual behaviours compared to HW. Similar to HW, a subgroup (25%) of severely females were engaging in higher rates of sexual risk behaviours and reported pregnancies and sexually transmitted infections (STIs). A considerable number (28–44%) reported receiving no birth control information from physicians.
Discussion topics with the adolescent patient should extend beyond reproductive health needs (e.g. contraception, unintended pregnancies) to include guidance around navigating romantic and sexual health behaviours that are precursors to these outcomes.

An estimated 350 million cases of STIs occur globally each year. In Sweden, Chlamydia is the most common STI with approximately 30 000 cases annually, disproportionally affecting youth. National surveys report low condom use among youth. Smartphone coverage is high among this tech-savvy group. In collaboration with youth, we developed an interactive smartphone application comprising games, peer experiences and information snippets to promote condom use.

Individual threespine sticklebacks (Gasterosteus aculeatus) presented with a choice of two stimuli (dummies or video images) that simulate prospective mates show a preference but nevertheless allocate a substantial proportion of their courtship effort to the less preferred one. The evidence presented here reveals additionally that mating preferences of male and female stickleback are expressed more strongly as their overall courtship response increases. This suggests that a more sexually aroused fish attends more to cues relevant to mate choice and is more selective of mates than less aroused fish are. This effect is likely to be mediated by a central process and could have significant impact on mate choice and sexual selection, at least in situations where prospective mates are encountered simultaneously.

Gonadotropin-releasing hormone (GnRH) was originally identified because of its essential role in regulating reproduction in all vertebrates. Since then, three phylogenetically related GnRH decapeptides have been characterized in vertebrates and invertebrates. Almost all tetrapods investigated have at least two GnRH forms (GnRH1 and GnRH2) in the central nervous system. From distributional and functional studies in vertebrates, GnRH1 in the hypothalamus projects predominantly to the pituitary and regulates reproduction via gonadotropin release. GnRH2, which is located in the midbrain, projects to the whole brain and is thought to be involved in sexual behaviour and food intake. GnRH3, located in the forebrain, has only been found in teleost fish and appears to be involved in sexual behaviour, as well as, in some fish species, gonadotropin release. Multiple GnRH receptors (GnRH-Rs), G-protein-coupled receptors regulate endocrine functions and neural transmissions in vertebrates. Phylogenetic and structural analyses of coding sequences show that all vertebrate GnRH-Rs cluster into two main receptor types comprised of four subfamilies. This suggests that at least two rounds of GnRH receptor gene duplications may have occurred in different groups within each lineage. Functional studies suggest that two particular subfamilies of GnRH receptors have independently evolved to act as species-specific endocrine modulators in the pituitary, and these show the greatest variety in regulating neuron networks in the brain. Given the long evolutionary history of the GnRH system, it seems likely that much more remains to be understood about its roles in behaviour and function of vertebrates. (C) 2008 The Authors.

This study was conducted to determine sexual experiences and gender differences in sexual behaviour in university students. In this cross-sectional and descriptive study conducted between 1(st) February and 12(th) November 2017. A total of 491 volunteer students were selected at a state university in the Mediterranean region of Turkey using a systematic sampling method. Questionnaires were distributed to the students in sealed envelopes and collected on completion. The data were collected using a socio-demographic form and a sexual experiences and sexual health behaviours form. A total of 414 students (78 males; 336 females) were included in this study. The prevalence of sexual intercourse among these was 4.3%, and total oral and anal sex experiences were 35% and 16.7%, respectively. A significantly higher number of female students of those who reported having sexual intercourse (n = 9; 50.0%), oral sex (n = 81; 55.9%) and anal sex (n = 60; 87.0%), also reported not telling anyone about his/her partner (77.2%), not talking about sex (82.4%) and not buying contraceptive products, even when necessary (78.3%). Hidden sexuality was seen to affect female students more often and this may lead to risky sexual behaviours, sexually transmitted diseases, an unhealthy sexual life with multiple partners and even unplanned, unwanted pregnancies.

The aim of the study was an empirical verification of a model assuming the influence of subjectively perceived sexual attractiveness and positive childbirth experience (PCE) (independent variables) on the level of women's sexual satisfaction after home birth or hospital birth (dependent variable) with the mediating involvement of subjectively perceived partner's support during pregnancy. The study was conducted with a group of 253 women after childbirth. Three standardised research tools were used in the study: the PCE Questionnaire, Sexual Satisfaction Questionnaire and Body Esteem Scale as well as original tools for the evaluation of subjectively perceived partner's support during pregnancy and childbirth. The empirical verification of the theoretical model was performed with the use of multiple regression methods. The level of subjectively perceived partner's support during pregnancy, level of attractiveness and PCE had influence on the level of women's sexual satisfaction. Such an influence was, however, not noticed in relation to the partner's presence during childbirth, level of partner's support during childbirth or role of the place of childbirth. Subjectively perceived partner's support during pregnancy is of key importance, mediating between PCE and the level of women's sexual satisfaction after childbirth.

Objectives The current guidelines aim to evaluate the role of pharmacological agents in the treatment of patients with compulsive sexual behaviour disorder (CSBD). They are intended for use in clinical practice by clinicians who treat patients with CSBD. Methods An extensive literature search was conducted using the English-language-literature indexed on PubMed and Google Scholar without time limit, supplemented by other sources, including published reviews. Results Each treatment recommendation was evaluated with respect to the strength of evidence for its efficacy, safety, tolerability, and feasibility. Psychoeducation and psychotherapy are first-choice treatments and should always be conducted. The type of medication recommended depended mainly on the intensity of CSBD and comorbid sexual and psychiatric disorders. There are few randomised controlled trials. Although no medications carry formal indications for CSBD, selective-serotonin-reuptake-inhibitors and naltrexone currently constitute the most relevant pharmacological treatments for the treatment of CSBD. In cases of CSBD with comorbid paraphilic disorders, hormonal agents may be indicated, and one should refer to previously published guidelines on the treatment of adults with paraphilic disorders. Specific recommendations are also proposed in case of chemsex behaviour associated with CSBD. Conclusions An algorithm is proposed with different levels of treatment for different categories of patients with CSBD.
