The need for early prevention approaches to improve young people's sexual and reproductive health is gaining attention, yet little is known about the sexual experiences of early adolescents aged 10-14 years. Drawing on cross-sectional survey data collected from 365 early adolescents in a Nairobi slum, we used latent class analysis to identify subgroups based on self-reported awareness about sex and involvement in romantic and sexual activities. Multivariate regression models were fitted to examine the characteristics of each subgroup...

Infertility is a disease characterized by the failure to establish a clinical pregnancy after 12 months of regular and unprotected sexual intercourse. It is estimated to affect between 8 and 12% of reproductive-aged couples worldwide. Males are found to be solely responsible for 20-30% of infertility cases but contribute to 50% of cases overall. Secondary infertility is the most common form of female infertility around the globe, often due to reproductive tract infections. The three major factors influencing the spontaneous probability of conception are the time of unwanted non-conception, the age of the female partner and the disease-related infertility...

OBJECTIVE: Since 2003, the Chinese central government has implemented several harm reduction and preventive measures to control HIV. We aim to describe epidemiological trends of HIV, hepatitis C virus (HCV), and syphilis in Guangxi drug users after the policy implementation. METHOD: A total of 12,161-15,870 drug users in Guangxi, China, were recruited annually from 2009 to 2015 through community outreach or snowball sampling. The participants' demographics, behavior, and infection status were used to characterize rates of protective behaviors and disease prevalence (HIV, syphilis, and HCV)...

Fracture of the penis is a well-recognized yet relatively uncommon urologic event. Forceful, blunt trauma with lateral bending of the penis in an erect state typically results in a transverse rupture of the tunica albuginea of the corpus cavernosum. Longitudinal tears of the corpus cavernosum are by themselves considered infrequent. We present a rare case of a patient with longitudinal rupture of the distal corpus cavernosum with concomitant extension to the corpus spongiosum causing partial urethral disruption as a result of trauma during sexual intercourse...

Background: Condoms remain the main protection against sexually transmitted infections (STIs) when used correctly and consistently. Yet, there are many reported barriers to their use such as negative attitudes, reduced sexual pleasure, fit-and-feel problems and erection difficulties. The UK home-based intervention strategy (HIS-UK) is a behaviour change condom promotion intervention for use among young men (aged 16-25 years) designed to increase condom use by enhancing enjoyment of condom-protected intercourse...

Background: Vulvodynia is an idiopathic vulvovaginal pain condition that has significant sexual and relational consequences. Most women with vulvodynia continue to have intercourse, possibly because of a desire to approach positive outcomes (e.g., intimacy) and avoid negative outcomes (e.g., partner disappointment). Purpose: This study examined daily associations between approach and avoidance sexual goals and women's pain during intercourse and couples' sexual and relational well-being, as well as the mediating role of sexual cues...

STUDY QUESTION: What is the natural conception rate over the course of 12 months in couples with unexplained or mild male subfertility who are scheduled for fertility treatment and have a predicted unfavourable prognosis for natural conception? SUMMARY ANSWER: The natural conception rate over the course of 12 months in couples who were allocated to treatment was estimated to be 24.5% (95% CI: 20-29%). WHAT IS KNOWN ALREADY: After starting treatment, couples often perceive unsuccessful cycles as evidence of definitive failure even though they are still able to conceive naturally in between and after treatment...

In human females, direct or indirect stimulation of the clitoris plays a central role in reaching orgasm. A majority of women report that penetrative coitus alone is insufficient for triggering orgasm, puzzling researchers who expect orgasm to be an outcome of procreative intercourse. In the present paper, we turn our attention to the evolutionary role that such unreliability of orgasm at coitus might have played in human evolution. We emphasize that we do not thereby attempt an explanation of its origin, but its potential evolutionary effect...

Objective: The human immunodeficiency virus (HIV) is among the utmost destructive viruses humankind has ever faced in almost four decades. It carries with it profound socioeconomic and public health implications. Unfortunately, there is, currently, no effective cure for HIV infections. This review discusses the various types of condoms, microbicides, and the potential use of nanoparticle-coated condoms as a means of diminishing the risk of HIV transmission and sexually transmitted infections (STIs) during sexual intercourse...

INTRODUCTION: Gay and bisexual men (GBM) often use illicit drugs to enhance sexual pleasure, commonly referred to as 'chemsex' or 'party n play'. In particular, the use of methamphetamine and Viagra™, and other erectile dysfunction medications, both together and separately are strongly predictive of subsequent HIV infection. Truvada™, as pre-exposure prophylaxis (PrEP), virtually eliminates HIV transmission during condomless anal intercourse (CLAI). HIV-negative GBM in intensive sex partying networks may be adding PrEP to their drug regimen to actively reduce the possibility of HIV transmission during chemsex...

During pregnancy, women go through a series of physical and emotional changes that may have an impact on their sexuality. The aim of the study was to examine modifications in sexual function during pregnancy by means of translabial ultrasonography and administration of questionnaires on sexual activity. Eighteen healthy and adult (25-35 years) pregnant women without sexual dysfunction and with a stable heterosexual relationship were examined at 10-12, 18-20, and 30-32 weeks of gestation. Patients underwent ultrasonographic translabial clitoral volume and labia minora thickness measurements and color Doppler assessment of the dorsal clitoral and posterior labial arteries...
