ABSTRACT. Objective. To identify psychosocial differences between sexually experienced male adolescents who indicate intentions to get someone pregnant and those who do not.Methodology. Cross-sectional study of 101 sexually experienced adolescent males recruited from a sexually transmitted disease clinic in northern California. We used Student's t tests and regressions to examine psychosocial differences between males who reported any intention versus no intention to get someone pregnant in the next 6 months, and we used analyses of variance to examine differences among different combinations of pregnancy plans/likelihood.Results. Adolescents' reports of their plans for getting someone pregnant differed from their assessments of the likelihood that they would do so ( 2 ؍ 24.33; df ؍ 1). A lthough teen pregnancy rates have dropped in recent years, a sizeable number of girls 15 to 19 years old still become pregnant each year. In 2000, 330 000 girls Ͻ18 years old became pregnant in the United States, and 166 000 gave birth. 1 More than 75% of teen pregnancies are considered unplanned or unintended, and ϳ35% of all teen pregnancies end in abortion. 2 For adolescents continuing a pregnancy, ϳ40% to 60% of births are considered to be the result of unintended pregnancies. [2][3][4][5][6] The vast majority of research studies examining adolescent pregnancy have focused solely on female adolescents' pregnancy attitudes, intentions, and behaviors. However, male partners play a role in determining the frequency of sexual intercourse 7 and the use of contraceptives. [8][9][10] Male partners also exert strong influence on female adolescents' intentions to conceive 4,11,12 as well as their decisions regarding and adjustment to a pregnancy termination. 13 Male pregnancy intentions can also affect the psychological and emotional responses to the children born as a result of a given pregnancy. Research has demonstrated that disagreements in pregnancy intentions between mothers and fathers can affect infants' health and well-being. Such disagreements occur about one fourth of the time. 14,15 Studies of adolescent males indicate a range of attitudes toward pregnancy. Some indicate that getting someone pregnant is a marker of manhood, 16 and making it known that they have fathered a child can elevate their social standing (even if they take no additional child-rearing actions). 15 Others report the potentially negative consequences for their futures 17 and recognize the additional responsibilities that they would need to take on. 18,19 Understanding male adolescents' motivations for getting someone pregnant and the factors (ie, attitudes, beliefs, and intentions) that characterize those male adolescents who indicate a desire to get someone pregnant may aid in efforts to reduce the negative health consequences of teenage childbearing in the United States. Adolescent pregnancies are often characterized by delayed initiation of prenatal care, poor prenatal health behaviors, and low birth weight infants. [20][21][22] Recent work al...
