Unprotected sexual intercourse between persons residing in or traveling from regions with Zika virus transmission is a risk factor for infection. To model risk for infection after sexual intercourse, we inoculated rhesus and cynomolgus macaques with Zika virus by intravaginal or intrarectal routes. In macaques inoculated intravaginally, we detected viremia and virus RNA in 50% of macaques, foll...
It is essential that physicians who take care of adolescents, whether in specialty practice or primary care, learn to routinely address adolescent sexuality and reproductive health care. According to our most recent Youth Risk Behavior Survey, 64.1% of 12th graders have had sexual intercourse ≥1 time, and 49.3% of 12th graders have had sexual intercourse with at least ≥1 person in the last 3 mo...
Abstinence from sexual intercourse can be a healthy choice for adolescents, particularly if an adolescent is not ready to engage in sex. However, government programs exclusively promoting abstinence-only-until-marriage (AOUM) are problematic from scientific and ethical viewpoints. Most young people initiate sexual intercourse as adolescents or young adults, and given a rising age at first marri...

METHODS A representative sample of 4.456 adolescents participated. To select the participants, a stratified random ...
Objective. – Inspite of unquestionable progress, the protection of girls at first sexual intercourse is still not perfect. The main risks are well known (sexually transmitted infections [STIs], unwanted pregnancies, psychological consequences) and seem to be higher in the case of early sexual initiation. The aim of this epidemiological study is to analyse factors associated with early heterosex...
In order to examine factors associated with orgasm in heterosexual encounters, we analyzed data from the Australian Study of Health and Relationships, a national telephone survey of sexual behavior and attitudes and sexual health knowledge carried out in 2001-2002 with a representative sample of 19,307 Australians aged 16 to 59. Respondents were asked whether at their last sexual encounter they...
High-risk human papillomavirus (HPV) types cause most cervical carcinomas and are sexually transmitted. Sexual behavior therefore affects HPV exposure and its cancer sequelae. The International Collaboration of Epidemiological Studies of Cervical Cancer has combined data on lifetime number of sexual partners and age at first sexual intercourse from 21 studies, or groups of studies, including 10...
We prospectively evaluated the effect of the treatment of lower urinary tract symptoms (LUTS) on sexual function. The patients were assessed by using the International Index of Erectile Function (IIEF-15) inventory at baseline and three months after medical (alpha-blockers) or surgical treatment (transurethral resection of the prostate, TURP). Following treatment, there were improvement in erec...
