The Complexities of Sex Education in Utah
1 The Complexities of Sex Education in Utah Grace Sponaugle Occidental College, Urban & Environmental Policy Professor Cha, Professor Matsuoka, & Professor Shamasunder April 8, 2019 Sponaugle 2 Abstract Utah has a state-wide policy of abstinence education. Abstinence education programs have been proven to be ineffective at delaying the initiation of sex and changing sexual risk behaviors (Santelli et al., 2017), correlating with high rates of teen pregnancies and STIs ((Stanger-Hall & Hall, 2011)(McCammon, 2017)). Limiting the standards by which sex education programs are deemed “effective” to disease and pregnancy prevention, neglects the holistic view of sexual health as defined by the CDC. Therefore, in an attempt to understand the broader implications that sex education has had on youth in Utah, this study examined, through a survey and interviews, the social, cultural, and educational influences that youth in Utah attributed to their sex education. Additionally, this study analyzed how these influences have played a role in the youth’s self perception of their sexual knowledge and sexual health. This research revealed that abstinence education is inherently limited, calling for Utah to expand its sex education framework beyond abstinence education and embrace a comprehensive model for sex education. Sponaugle 3 Acknowledgements First, I would like to thank Professor Cha, Professor Matsuoka, and Professor Shamasunder for their help and guidance not only on the completion of my thesis, but also throughout my journey at Occidental College. Additionally, I would like to thank everyone that participated in the survey and interviews. None of this would have be possible without your support and interest in my project. -
Human Reproductive Systems Males Vs. Females Learning Goals • Students Will Describe the Basic Anatomy and Physiology of the Male and Female Reproductive Systems
Human Reproductive Systems Males vs. Females Learning Goals • Students will describe the basic anatomy and physiology of the male and female reproductive systems. Gonads are sex organs that create gametes? & excrete sex hormones Gonads are sex organs that create gametes & excrete sex hormones Male gonads are called testes Female gonads are called ovaries -Are the site of sperm production -Are the site of egg production & maturation Gametes are also called sex ?cells, and are used to create offspring with a mixture of genetic information. Gametes are also called sex cells, and are used to create offspring with a mixture of genetic information. Male gametes are called sperm Female gametes are called -produce 300-500 million per 5ml eggs/ova of semen -70,000-100,000 at birth -release 1-2 per month from puberty to menopause. Sex Hormones are chemical? signals that tell the sex organs how to function. Sex Hormones are chemical signals that tell the sex organs how to function. Male hormone is called Female hormones are estrogen testosterone and progesterone -released from the testes -released from the ovary -controls sperm production -controls egg production & release Duct systems help deliver gametes from gonads and are the site of fertilization in females and delivers sperm out of the body in males. Male duct systems include: Epididymis -site of sperm maturation (about 20 days for sperm to mature) Male duct systems include: Vas deferens -Tube for sperm to travel through as they leave the testes Male duct systems include: Urethra -shared tube for release of semen from reproductive tract and urine from the bladder. -
Perceptions of a School-Based Sexuality Education Curriculum: Findings from Focus Groups with Parents and Teens in a Southern State
Perceptions of a School-Based Sexuality Education Curriculum: Findings from Focus Groups with Parents and Teens in a Southern State S. Alexandra Marshall, Heather K. Hudson, and Lorraine V. Stigar Abstract School-based sexuality education is widely supported by most Americans. However, there is debate over the topics that should be taught. Also, a better understanding of desires adolescents and parents have for equipping youth to make healthy decisions is needed. This study gathered perceptions from parents and students about the sexuality education curriculum being implemented in selected, priority high schools in Arkansas. Separate parent and student focus groups were conducted at four of the fifteen priority high schools with high rates of sexually transmitted infection (STI) and teen pregnancy. Common themes included: 1) sex education should be comprehensive and is currently inadequate; 2) characteristics valued in friendships are not currently reinforced in schools leaving a disconnect for students when it comes to healthy romantic relationships; 3) students feel ill-equipped to pursue healthy dating relationships and lack realistic role models for healthy dating relationships; and 4) many teens are believed to be in abusive dating relationships. A comprehensive sexuality education curriculum is recommended to better address all relationship types and equip students to make healthy decisions in the context of their relationships. *S.

Abstract: For centuries, scientists have been intrigued by the origin of dioecy in plants, characterizing sex-specific development, uncovering cytological differences between the sexes, and developing theoretical models. Through the invention and continued improvements in genomic technologies, we have truly begun to unlock the genetic basis of dioecy in many species. Here we broadly review the advances in research on dioecy and sex chromosomes. We start by first discussing the early works that built the foundation for current studies and the advances in genome sequencing that have facilitated more-recent findings. We next discuss the analyses of sex chromosomes and sex-determination genes uncovered by genome sequencing. We synthesize these results to find some patterns are emerging, such as the role of duplications, the involvement of hormones in sex-determination, and support for the two-locus model for the origin of dioecy. Though across systems, there are also many novel insights into how sex chromosomes evolve, including different sex-determining genes and routes to suppressed recombination. We propose the future of research in plant sex chromosomes should involve interdisciplinary approaches, combining cutting-edge technologies with the classics Citation: Carey, S.; Yu, Q.; to unravel the patterns that can be found across the hundreds of independent origins. -

Effectiveness of Sex Education in Adolescents
Study Protocol Effectiveness of Sex Education in Adolescents Aroa Cortínez-López 1, Daniel Cuesta-Lozano 2,* and Raquel Luengo-González 2 1 Obstetric Unit, Clinic University of Navarra, 28027 Madrid, Spain; [email protected] 2 Nursing and Physiotherapy Department, University of Alcala, Alcalá de Henares, 28805 Madrid, Spain; [email protected] * Correspondence: [email protected] Abstract: Adolescence is the time during which the personal and sexual identity develops. The specific characteristics of adolescents and the lack of maturity facilitates the acquisition of sexual risk behaviors such as relaxation in the use of barrier contraceptives or the use of toxic substances, alcohol or drugs during sexual relations, increasing of sexually transmitted infections (STIs) and unwanted pregnancies. Health education in sexuality is one of the best ways to prevent risk behaviors and to promote healthy and responsible sexuality. While there have been different works in sex education in adolescents, there is still a lack of a comprehensive systematic literature review that including randomized and non-randomized clinical trials and quasi-experimental pre-post studies addressing education programs that provide information on healthy and responsible sexuality. Further, it is noted that a protocol drafted in consideration of the existing approaches is needed to present a basis for a systematic literature review in this area. This article, therefore, proposes a review protocol that will evaluate the impact of comprehensive sex education programs in the level of knowledge about STIs, behavioral level concerning the frequency of use of effective contraceptive methods and level of knowledge about sexual identity, diversity and/or responsible sexuality, after the intervention. -

It can give us knowledge about our bodies; debunk harmful stereotypes about sex, race, and gender; provide opportunities for us to think critically about our own values and relationships; and empower us to stand up for our rights and the rights of others to pleasure, bodily autonomy, and consent. This was not, however, what sex education was initially designed to do. Too often, over the past 100 years of American history, it has been used to do just the opposite. 4 5 Those who originally pushed the importance of SIECUS believes, however, that sex education— educating the public about sexuality did so out if done properly—has the power to serve as a of a fear that their comfortable, white, middle vehicle for social change. Understanding the class way of living was being threatened by the history of sex education in this country, the loosening of sexual morals.
