ADOLESCENT SEXUALITY, AGE DISCREPANCY, SEX ABUSE AND BIRTH CONTROL

     According to information available from the Guttmacher Institute, sex by age 20 is the normal age across the world, and countries with low levels of adolescent pregnancy accept sexual relationships among teenagers and provide comprehensive and balanced information about sexuality.

However, in a Kaiser Family Foundation study of US teenagers, 29% of teens reported feeling pressure to have sex, 33% of sexually active teens reported "being in a relationship where they felt things were moving too fast sexually", and 24% had "done something sexual they didn’t really want to do". Several polls have indicated peer pressure as a factor in encouraging both girls and boys to have sex. Inhibition-reducing drugs and alcohol may possibly encourage unintended sexual activity. If so, it is unknown if the drugs themselves directly influence teenagers to engage in riskier behavior, or whether teenagers who engage in drug use are more likely to engage in sex. Correlation does not imply causation. The drugs with the strongest evidence linking to teenage pregnancy are cannabis, alcohol, and amphetamines, including "ecstasy". The drugs with the least evidence to support a link to early pregnancy are opioids, such as heroin, morphine, and oxycodone, of which a well-known effect is the significant reduction of libido – it appears that teenage opioid users have significantly reduced rates of conception compared to their non-using, and cannabis, alcohol, and amphetamine using peers. Amphetamines are widely prescribed to treat ADHD – internationally, the countries with the highest rates of recorded amphetamine prescription to teenagers also have the highest rates of teenage pregnancy.

                                                          Birth control

 Adolescents may lack knowledge of, or access to, conventional methods of preventing pregnancy, as they may be too embarrassed or frightened to seek such information. Contraception for teenagers presents a huge challenge for the clinician. In 1998, the government set a target to halve the under-18 pregnancy rate by 2010. The Teenage Pregnancy Strategy (TPS) was established to achieve this. The pregnancy rate in this group, although falling, rose slightly in 2007, to 41.7 per 1000 women. Young women often think of contraception either as 'the pill' or condoms and have little knowledge about other methods. They are heavily influenced by negative, second-hand stories about methods of contraception from their friends and the media. Prejudices are extremely difficult to overcome. Over concern about side-effects, for example weight gain and acne, often affect choice. Missing up to three pills a month is common, and in this age group the figure is likely to be higher. Restarting after the pill-free week, having to hide pills, drug interactions and difficulty getting repeat prescriptions can all lead to method failure.

In the United States, according to the 2002 National Surveys of Family Growth, sexually active adolescent women wishing to avoid pregnancy were less likely than those of other ages to use contraceptives (18% of 15- to 19-year-olds used no contraceptives, versus 10.7% average for women ages 15 to 44). More than 80% of teen pregnancies are unintended. Over half of unintended pregnancies were to women not using contraceptives, most of the rest are due to inconsistent or incorrect use. 23% of sexually active young women in a 1996 Seventeen magazine poll admitted to having had unprotected sex with a partner who did not use a condom, while 70% of girls in a 1997 PARADE poll claimed it was embarrassing to buy birth control or request information from a doctor.

Among teens in the UK seeking an abortion, a study found that the rate of contraceptive use was roughly the same for teens as for older women.

In other cases, contraception is used, but proves to be inadequate. Inexperienced adolescents may use condoms incorrectly or forget to take oral contraceptives. Contraceptive failure rates are higher for teenagers, particularly poor ones, than for older users. Reversible longer term methods such as intrauterine devices, subcutaneous implants, or injections (Depo provera, Combined injectable contraceptive), require less frequent user action, lasting from a month to years, and may prevent pregnancy more effectively in women who have trouble following routines, including many young women. The simultaneous use of more than one contraceptive measure further decreases the risk of unplanned pregnancy, and if one is a condom barrier method, the transmission of sexually transmitted disease is also reduced.

                                          Age discrepancy in relationships

According to the conservative lobbying organization Family Research Council, studies in the US indicate that age discrepancy between the teenage girls and the men who impregnate them is an important contributing factor. Teenage girls in relationships with older boys, and in particular with adult men, are more likely to become pregnant than teenage girls in relationships with boys their own age. They are also more likely to carry the baby to term rather than have an abortion. A review of California's 1990 vital statistics found that men older than high school age fathered 77 percent of all births to high school-aged girls (ages 16–18), and 51 percent of births to junior high school-aged girls (15 and younger). Men over age 25 fathered twice as many children of teenage mothers than boys under age 18, and men over age 20 fathered five times as many children of junior high school-aged girls as did junior high school-aged boys. A 1992 Washington state study of 535 adolescent mothers found that 62 percent of the mothers had a history of being raped or sexual molested by men whose ages averaged 27 years. This study found that, compared with nonabused mothers, abused adolescent mothers initiated sex earlier, had sex with much older partners, and engaged in riskier, more frequent, and promiscuous sex. Studies by the Population Reference Bureau and the National Center for Health Statistics found that about two-thirds of children born to teenage girls in the United States are fathered by adult men age 20 or older

Sexual abuse

                                                     Sexual abuse

Studies have found that between 11 and 20 percent of pregnancies in teenagers are a direct result of rape, while about 60 percent of teenage mothers had unwanted sexual experiences preceding their pregnancy. Before age 15, a majority of first-intercourse experiences among females are reported to be non-voluntary; the Guttmacher Institute found that 60 percent of girls who had sex before age 15 were coerced by males who on average were six years their senior.[citation needed] One in five teenage fathers admitted to forcing girls to have sex with them.

Multiple studies have indicated a strong link between early childhood sexual abuse and subsequent teenage pregnancy in industrialized countries. Up to 70 percent of women who gave birth in their teens were molested as young girls; by contrast, 25 percent for women who did not give birth as teens were molested.

In some countries, sexual intercourse between a minor and an adult is not considered consensual under the law because a minor is believed to lack the maturity and competence to make an informed decision to engage in fully consensual sex with an adult. In those countries, sex with a minor is therefore considered statutory rape. In most European countries, by contrast, once an adolescent has reached the age of consent, he or she can legally have sexual relations with adults because it is held that in general (although certain limitations may still apply), reaching the age of consent enables a juvenile to consent to sex with any partner who has also reached that age. Therefore, the definition of statutory rape is limited to sex with a person under the minimum age of consent.
