Human Sexuality and Reproductive Health: Biological and Clinical Perspectives

Sexuality: Definitions and Terminology

Overview of Sexuality

Sexuality is a multifaceted aspect of human biology and psychology, encompassing biological sex, sexual activity, gender identities and roles, and sexual orientation. Sexual health integrates somatic, emotional, intellectual, and social aspects of sexual being in ways that are positively enriching.

• Biologic sex: Determined by chromosomal development (e.g., XX for female, XY for male).

• Gender identity: An individual's personal sense of their gender, which may or may not correspond with their biological sex.

• Gender role behavior/expression: The outward expression of gender, including behaviors, clothing, and interests.

• Sexual orientation: The pattern of romantic or sexual attraction to others (e.g., heterosexual, homosexual, bisexual).

Key Terminology

• Gender identity: Internal sense of being male, female, both, neither, or somewhere along the gender spectrum.

• Gender expression: How a person outwardly shows their gender identity.

• Gender diverse: Individuals whose gender identity or expression differs from societal expectations.

• Gender dysphoria: Distress caused by a discrepancy between a person's gender identity and their assigned sex at birth.

• Cisgender: A person whose gender identity matches their sex assigned at birth.

• Transgender: A person whose gender identity differs from their sex assigned at birth.

• Gender binary: The classification of gender into two distinct, opposite forms (male and female).

• Gender fluid: A gender identity or expression that varies with time.

Sexual Orientation

• Heterosexual: Attraction to individuals of the opposite gender.

• Gay or lesbian: Attraction to individuals of the same gender.

• Bisexual: Attraction to both men and women.

• Asexual: Lack of sexual attraction to others.

• Questioning: Exploring or uncertain about one's sexual orientation.

Sexual Expression and Health

Sexual Expression

Sexual expression ranges from adaptive (healthy) to maladaptive (unhealthy) behaviors.

• Masturbation: Self-stimulation of the genitals for sexual pleasure.

• Sexual intercourse: Vaginal or anal penetration between partners.

• Oral–genital stimulation: Oral contact with the genitals.

• Abstinence: Choosing not to engage in sexual activity.

• Alternative expressions: May include voyeurism, sadism, masochism, sadomasochism, and pedophilia (the latter is illegal and considered a psychiatric disorder).

Factors Affecting Sexuality

• Developmental considerations: Age and stage of life influence sexual development and expression.

• Culture: Cultural norms and values shape sexual attitudes and behaviors.

• Religion: Religious beliefs may influence sexual practices and values.

• Ethics: Personal and societal ethics guide sexual behavior.

• Lifestyle: Personal choices and habits impact sexual health.

Human Reproductive Physiology

Menstruation and the Ovarian Cycle

Menstruation is the normal vaginal bleeding that prepares the uterus for the presence of a fertilized ovum. The menstrual cycle is divided into four phases:

• Follicular phase: One follicle in the ovary matures and produces an ovum.

• Proliferation phase: The endometrial lining of the uterus becomes thick and velvety.

• Luteal phase: The corpus luteum forms and secretes hormones to support a potential pregnancy.

• Secretory phase: The endometrial lining disintegrates if fertilization does not occur, leading to menstruation.

• Menopause: The permanent cessation of menstrual activity, typically occurring between ages 45-55.

Causes of Menstrual Cycle Irregularities

• Pregnancy or breast-feeding

• Eating disorders, extreme weight loss, or excessive exercise

• Polycystic ovary syndrome (PCOS)

• Premature ovarian failure

• Pelvic inflammatory disease (PID)

• Uterine fibroids

Sexual Response Cycle

Phases of the Sexual Response Cycle

The sexual response cycle consists of four phases:

• Excitement: Initial arousal and increased blood flow to the genitals.

• Plateau: Heightened arousal and sustained sexual tension.

• Orgasm: Climax of sexual tension, characterized by involuntary spasmodic contractions of the genital organs.

• Resolution: Return to the unaroused state.

Example: Involuntary spasmodic contractions of the genital organs occur during the orgasm phase.

Sexually Transmitted Infections (STIs)

Common STIs

• HIV (Human Immunodeficiency Virus)

• Bacterial vaginosis (BV)

• Chlamydia

• Cytomegalovirus

• Genital herpes

• Gonorrhea

• Human papillomavirus (HPV)

• Syphilis

• Trichomoniasis

Prevention of STIs

• Delay initiation of sexual activity

• Have regular checkups for STIs

• Learn the common symptoms of STIs

• Avoid sexual activity during menstruation

• Avoid anal intercourse

• Avoid douching

Sexual Dysfunction

Male Sexual Dysfunction

• Erectile dysfunction: Inability to achieve or maintain an erection.

• Premature ejaculation: Ejaculation that occurs sooner than desired.

• Delayed ejaculation: Difficulty or inability to ejaculate.

Female Sexual Dysfunction

• Inhibited sexual desire: Reduced interest in sexual activity.

• Dyspareunia: Painful intercourse.

• Vaginismus: Involuntary contraction of vaginal muscles, making intercourse difficult or painful.

• Vulvodynia: Chronic pain or discomfort of the vulva.

Effects of Illness, Injury, and Medications

• Diabetes mellitus

• Cardiovascular disease

• Diseases affecting joints and mobility

• Surgery and changes in body image

• Spinal cord injuries

• Chronic pain

• Mental illness

• Medications (e.g., antihypertensives, antidepressants)

Sexual Harassment and Professional Boundaries

Forms of Sexual Harassment

• Quid pro quo: Something is withheld in exchange for sexual favors.

• Environmental (hostile environment): Unwelcome sexually oriented and gender-based behaviors that create a hostile work environment.

Hostile Work Environment Examples

• Sexual bantering and joking

• Offensive pictures and language

• Sexual innuendoes and behaviors

• Unwanted attention

Responding to Patient Advances and Harassment

• Be self-aware and set clear boundaries

• Confront and provide feedback to the patient or coworker

• Document incidents and report to supervisors

• File grievances or seek legal advice if necessary

Assessment and Nursing Interventions

Nursing History

• Reproductive history

• History of STIs and sexual dysfunction

• Sexual self-care behaviors

• Sexual self-concept and functioning

The BETTER Model for Addressing Sexuality

• BRING up the topic of sexuality

• EXPLAIN concern for all aspects of patients’ lives

• TELL patients that sexual dysfunction can occur and will be addressed

• TIMING is important; address sexuality at each visit

• EDUCATE about treatment side effects

• RECORD assessments and interventions in medical records

Physical Assessment

• Physical examination

• Annual gynecologic exam with Pap smear

• Assessment for suspected STI or pregnancy

• Workup for infertility

• Evaluation of unusual lumps, discharge, or genital appearance

• Requests for birth control or changes in urinary function

Patient Outcomes Regarding Sexuality

• Define individual sexuality

• Establish open communication with significant others

• Develop self-awareness and body awareness

• Describe responsible sexual health self-care practices

• Practice responsible sexual expression

Implementation Strategies

• Establish a trusting nurse-patient relationship

• Teach about sexuality and sexual health

• Promote responsible sexual expression and contraception

• Facilitate coping with special sexual needs

• Address health care needs of LGBTQ+ individuals

• Advocate for patients’ sexuality needs

• Counsel patients regarding sexuality, abortion, abuse, or rape

Contraception

Methods of Contraception

• Behavioral: Methods such as abstinence, fertility awareness, and withdrawal.

• Barrier: Physical or chemical barriers to prevent sperm from reaching the egg.

• Hormonal: Use of hormones to prevent ovulation (e.g., birth control pills).

• Intrauterine devices (IUDs): Devices placed in the uterus to prevent pregnancy.

• Emergency contraception: Methods used after unprotected sex to prevent pregnancy.

• Sterilization: Permanent methods such as tubal ligation or vasectomy.

Barrier Methods of Contraception

Method	Description
Condom	Sheath placed over the penis or inside the vagina to prevent sperm entry.
Diaphragm	Dome-shaped rubber device placed in the vagina before intercourse to cover the cervix and block sperm.
Cervical cap	Small cap that fits over the cervix to block sperm entry.
Spermicides	Chemical agents that kill sperm, used alone or with other barrier methods.
Vaginal sponge	Sponge containing spermicide placed in the vagina before intercourse.

Example: The diaphragm is a barrier method of contraception in which a dome-shaped rubber device is placed in the vagina before sexual activity to prevent semen from coming into contact with the cervix.
