🚑Contemporary Health Issues Unit 10 – Reproductive and Sexual Health

Key Concepts and Terminology

• Reproductive health encompasses the physical, mental, and social well-being related to the reproductive system and its functions throughout life
• Sexual health involves a positive and respectful approach to sexuality and sexual relationships, free from coercion, discrimination, and violence
• Contraception methods (hormonal, barrier, intrauterine devices) prevent pregnancy by interfering with ovulation, fertilization, or implantation
• Sexually transmitted infections (STIs) are infections passed from one person to another through sexual contact (chlamydia, gonorrhea, HIV)
• Family planning enables individuals and couples to attain their desired number of children and determine the spacing of pregnancies through contraceptive use and infertility treatment
• Reproductive rights include the right to decide freely and responsibly on matters related to sexuality, reproduction, and access to health services
• Maternal health refers to the health of women during pregnancy, childbirth, and the postpartum period

Anatomy and Physiology Basics

• The female reproductive system consists of internal organs (ovaries, fallopian tubes, uterus, cervix, vagina) and external genitalia (vulva)
  • Ovaries produce eggs (ova) and hormones (estrogen and progesterone)
  • Fallopian tubes transport the egg from the ovary to the uterus
  • The uterus is where the fertilized egg implants and the fetus develops
• The male reproductive system includes the testes, epididymis, vas deferens, seminal vesicles, prostate gland, and penis
  • Testes produce sperm and testosterone
  • The epididymis stores and matures sperm
  • The vas deferens transports sperm from the epididymis to the ejaculatory ducts
• The menstrual cycle is a series of natural changes in hormone production and the structures of the uterus and ovaries, enabling pregnancy
  • Follicular phase involves the development of follicles in the ovaries
  • Ovulation occurs when a mature egg is released from the ovary
  • Luteal phase prepares the uterus for potential implantation of a fertilized egg
• Spermatogenesis is the process of sperm production in the testes, which begins at puberty and continues throughout a man's life
• Fertilization occurs when a sperm cell penetrates and fuses with an egg cell in the fallopian tube, forming a zygote

Reproductive Health Across the Lifespan

• Puberty marks the onset of reproductive maturity, characterized by physical changes (breast development, menstruation in females; testicular enlargement, voice deepening in males) and emotional changes
• Adolescence is a critical period for developing healthy attitudes and behaviors related to sexuality and relationships
• Preconception health refers to the health of women and men during their reproductive years before pregnancy occurs, which can impact pregnancy outcomes
• Menopause is the natural cessation of menstruation, typically occurring between ages 45-55, accompanied by hormonal changes (decreased estrogen) and symptoms (hot flashes, vaginal dryness)
• Andropause, or male menopause, is a gradual decline in testosterone levels with age, which can affect sexual function, muscle mass, and bone density
• Reproductive aging can impact fertility, with a decrease in egg quantity and quality in women and a decline in sperm motility and morphology in men
• Sexual function may change with age due to hormonal shifts, chronic health conditions, medications, and psychosocial factors (relationship issues, stress)

Sexual Health and Wellness

• Sexual orientation refers to a person's emotional, romantic, and sexual attraction to others (heterosexual, homosexual, bisexual, asexual)
• Gender identity is a person's internal sense of being male, female, neither, or other genders, which may or may not correspond with their sex assigned at birth
• Sexual pleasure is a natural and healthy aspect of sexuality, involving physical and emotional satisfaction derived from sexual activities
• Communication is essential for healthy sexual relationships, including discussing boundaries, desires, and concerns with partners
• Consent is a clear, voluntary, and ongoing agreement to engage in sexual activity, which can be withdrawn at any time
• Sexual dysfunction can affect individuals of all ages and may include issues with desire, arousal, orgasm, or pain (erectile dysfunction, vaginismus)
  • Treatment options include therapy, medications, and lifestyle changes
• Sexual violence, including sexual assault and intimate partner violence, can have profound physical, emotional, and psychological consequences for survivors

Contraception and Family Planning

• Hormonal contraceptives (birth control pills, patches, injections) work by altering the hormone levels to prevent ovulation and thicken cervical mucus
• Barrier methods (condoms, diaphragms, cervical caps) physically block sperm from reaching the egg
  • Male condoms also provide protection against STIs
• Intrauterine devices (IUDs) are small, T-shaped devices inserted into the uterus that prevent fertilization or implantation
• Natural family planning methods (rhythm method, basal body temperature tracking) involve identifying fertile days in the menstrual cycle to avoid pregnancy
• Emergency contraception (Plan B, Ella) can prevent pregnancy after unprotected sex or contraceptive failure if taken within a specific timeframe
• Sterilization (tubal ligation, vasectomy) is a permanent form of birth control that involves surgically blocking the fallopian tubes or vas deferens
• Contraceptive effectiveness is measured by the failure rate, or the percentage of women who experience an unintended pregnancy within the first year of use

Sexually Transmitted Infections

• STIs are caused by bacteria (chlamydia, gonorrhea, syphilis), viruses (HIV, HPV, herpes), or parasites (trichomoniasis)
• Transmission occurs through sexual contact, including vaginal, anal, and oral sex, as well as from mother to child during pregnancy or childbirth
• Symptoms can vary depending on the STI but may include genital discharge, pain, sores, or warts
  • Some STIs may be asymptomatic, emphasizing the importance of regular screening
• Diagnosis involves physical examination, laboratory tests (blood tests, urine samples, swabs), and sometimes imaging (ultrasound)
• Treatment depends on the specific STI and may include antibiotics, antiviral medications, or topical treatments
  • Some STIs, such as HIV and herpes, have no cure but can be managed with medication
• Prevention strategies include using condoms consistently and correctly, limiting the number of sexual partners, and getting vaccinated (HPV, hepatitis B)
• Partner notification is essential to prevent the spread of STIs and ensure that all affected individuals receive appropriate testing and treatment

Pregnancy and Childbirth

• Pregnancy begins with implantation of the fertilized egg in the uterus and lasts approximately 40 weeks, divided into three trimesters
• Prenatal care involves regular check-ups with a healthcare provider to monitor the health of the mother and fetus, including physical exams, ultrasounds, and screening tests
• Maternal nutrition and lifestyle choices (diet, exercise, avoiding alcohol and tobacco) can significantly impact fetal development and pregnancy outcomes
• Labor is the process of giving birth, characterized by regular uterine contractions and cervical dilation
  • Stages of labor include early labor, active labor, and the pushing stage
• Delivery can occur vaginally or through a cesarean section (C-section), a surgical procedure to remove the baby through incisions in the abdomen and uterus
• Postpartum care focuses on the physical and emotional recovery of the mother and the care of the newborn, including breastfeeding support and monitoring for complications (postpartum depression, infections)
• Perinatal mental health disorders, such as postpartum depression and anxiety, can affect women during pregnancy and after childbirth and require prompt recognition and treatment

Social and Cultural Aspects

• Gender roles and expectations can influence sexual attitudes, behaviors, and access to reproductive health services
• Stigma surrounding sexual health issues (STIs, abortion, infertility) can create barriers to seeking care and support
• Cultural and religious beliefs may impact decisions related to contraception, abortion, and sexual practices
• Comprehensive sexuality education provides age-appropriate, evidence-based information on sexual health topics to promote informed decision-making and healthy behaviors
• Media representations of sexuality and relationships can shape societal norms and individual perceptions, both positively and negatively
• LGBTQ+ individuals may face unique challenges in accessing inclusive and affirming reproductive and sexual health services
• Reproductive justice is a framework that emphasizes the right to bodily autonomy, to have or not have children, and to parent in safe and sustainable communities

Healthcare Access and Services

• Reproductive healthcare services include contraception, STI testing and treatment, prenatal care, abortion, and infertility treatment
• Access to healthcare can be influenced by factors such as insurance coverage, geographic location, and socioeconomic status
• Confidentiality is essential in reproductive healthcare, particularly for adolescents and individuals in vulnerable situations
• Telemedicine has expanded access to reproductive health services, particularly in rural or underserved areas
• Integrated care models, which combine reproductive health with primary care and mental health services, can improve health outcomes and patient satisfaction
• Healthcare disparities, such as higher rates of maternal mortality among Black women in the United States, highlight the need for equitable and culturally competent care
• Reproductive healthcare policies, such as funding for family planning services and abortion regulations, can significantly impact access to care

Current Issues and Debates

• Abortion remains a contentious issue, with ongoing debates about legal restrictions, access, and moral considerations
• Assisted reproductive technologies (in vitro fertilization, surrogacy) have raised ethical questions about the commodification of reproduction and the rights of all parties involved
• Maternal mortality rates have increased in some developed countries, prompting efforts to improve prenatal and obstetric care
• The COVID-19 pandemic has disrupted reproductive healthcare services and highlighted disparities in access and outcomes
• Climate change may have implications for reproductive health, such as increased risk of preterm birth and reduced fertility
• Efforts to promote sexual and reproductive health and rights globally face challenges related to funding, political opposition, and cultural barriers
• Advances in contraceptive technology, such as male contraceptive pills and longer-acting reversible contraceptives, may expand options for pregnancy prevention in the future
