Study Notes

Sexual Self

The sexual self encompasses sexual health, sexual orientation, gender identity and expression, and values related to sexuality.

Gonads (Sex Organs)

Reproductive glands (testes or ovaries) start developing around the 8th week of embryonic development.
Initially, male and female embryos have similar structures in a stage called the indifferent stage.

Differentiation of Sex Structures

Differentiation into male or female structures occurs due to the presence of testosterone.
Testosterone is the primary male hormone, regulating sex differentiation, the production of male sex characteristics, spermatogenesis, and fertility.

Embryos in Male and Female

In male embryos, the testes produce testosterone, leading to the development of male duct systems and external genitalia.
In female embryos, the absence of testosterone from the ovaries results in the formation of female ducts and external genitalia.

Hormonal Disruptions

Any disruption to the normal production of sex hormones during embryonic development can lead to abnormalities.
These abnormalities can result in conditions such as pseudohermaphrodites, individuals whose accessory reproductive structures don't match their gonads. Another possibility is a person whose external genitalia are different from their chromosomal sex, or true hermaphrodites with both ovarian and testicular tissues.

Cryptorchidism

This is a condition affecting young males.
It can lead to infertility, and increased risk of testicular cancer. Treatment often involves childhood surgery.

Abnormal Chromosomes

Separation errors during meiosis can result in reproductive system defects.
Females with only one sex chromosome (XO) have Turner syndrome; they lack ovaries. YO males don't survive development.
Milder conditions like phimosis (foreskin narrowing) and misplaced urethral openings affect primarily males.

Puberty

Puberty is the developmental period (generally between ages 10 and 15) when reproductive organs grow to their adult size and become functional due to rising gonadal hormone levels.

Male Puberty

Male puberty typically starts around age 13.
It involves reproductive organ growth, and hair appearance on pubic areas, underarms, and face.
Sexual maturation is marked by the presence of mature semen in the testes.

Female Puberty

In females, budding breasts around age 11 often signal puberty.
Menarche (the first menstrual period) occurs about two years after the start of puberty.
Hormones regulate ovulation and female fertility.

Diseases Associated with the Reproductive System

Infections are common problems, especially vaginal infections in young and older women.
Sexually transmitted microorganisms, such as chlamydia, gonorrhea, syphilis, herpes virus and yeast, are prevalent.
In males, common inflammatory conditions include prostatitis, urethritis, and epididymitis, often stemming from sexual contact.
Most women reach their peak reproductive ability in their late 20s.
Decline in ovarian function (common after 20s) impacts estrogen production, leading to irregular or shorter menstrual cycles.

Erogenous Zones

Erogenous zones are areas of the body that are sensorially receptive and heighten sexual arousal when stimulated.

Human Sexual Behavior

Human sexual behaviour encompasses a wide array of physical and psychological activities encompassing sexual arousal, desire, and satisfaction.
Types of behaviour are usually categorized by gender and number of participants.

Solitary Behavior (Masturbation)

Self-stimulation that leads to sexual arousal and climax.
Very common in young males, often starting before puberty.

Sociosexual Behaviour

Heterosexual behaviour refers to sexual interactions between one male and one female.
This is the most common sociosexual behavior example.

Petting

A form of sexual activity involving touching and kissing of the clothed body, not involving stimulation of genitals.

Coitus

The insertion of the male reproductive structure into the female reproductive organ.
Viewed differently by societies based on the individuals' marital status.
Pre-marital coitus (sex) is more readily tolerated but not promoted by many cultures if the involved individuals intend marriage.

Physiology of Human Sexual Response

Sexual response follows a sequential pattern (or phases) during sexual activity.

Four Types of Sexual Response

Excitation Phase: Increased pulse and blood pressure.
Plateau Phase: Brief duration. Orgasm often happens with continued stimulation.
Sexual Climax: Marked by pleasure, increased pulse and blood pressure, pelvic muscle spasms, and potentially involuntary vocalizations.
Resolution Phase: Return to a normal physiological state.

Nervous System Factors

The entire nervous system plays a key role during sexual response.
The autonomic nervous system controls involuntary responses.
Efferent cerebrospinal nerves transmit sensory messages to the brain.

Sexual Problems

Often physiological, psychological, or social in origin.

Physiological Issues

Typically infections or hormonal imbalances, generally rare.
Treatable by medication or surgery.

Psychological Issues

Societal pressures and myths often contribute to anxiety and inadequacy, leading to problems.

Examples of Psychological Factors and Causes

Performance anxiety, leading to erectile dysfunction.
Past trauma influencing sexual dysfunction (e.g., premature ejaculation, vaginismus).

Sexually Transmitted Diseases (STDs)

Infections spread through sexual contact (bacteria, viruses, or parasites).
AIDS is one of the leading STDs globally.
Interconnected with HIV, STDs substantially impact women and infants, causing various health issues.
Examples include Chlamydia, Gonorrhea, Syphilis, Chancroid, Human Papillomavirus (HPV), Herpes Simplex Virus, and Trichomonas vaginalis. Potential issues include pelvic inflammatory disease, infertility, ectopic pregnancies, cervical cancer, perinatal or congenital infections in infants.

Natural and Artificial Contraception Methods

Natural methods avoid chemicals or foreign objects in the body.
Religious beliefs and cost-effectiveness often drive the choice of natural methods.

Natural Contraception Methods

Abstinence: Refraining from sexual intercourse.
Calendar Method: Tracking menstrual cycles to avoid fertile periods based on ovulation.
Basal Body Temperature (BBT): Tracking body temperature changes to pinpoint ovulation.
Cervical Mucus Method: Analyzing mucus changes to detect fertile periods.
Symptothermal Method: Combining BBT and cervical mucus to determine ovulation.
Ovulation Detection (using test kits): Kits that analyze urine for ovulation prediction

Artificial Contraception Methods

Oral Contraceptives (The Pill): Hormonal pills taken daily to regulate ovulation and other hormones.
Transdermal Patch: A patch worn on the skin that releases hormones into the body.
Vaginal Ring: A ring inserted into the vagina that releases hormones.
Hormonal Injections: Injections that prevent ovulation by releasing progestogens.
Intrauterine Devices (IUDs): Devices inserted into the uterus to prevent fertilization.
Diaphragm/Cervical Cap: Devices covering the cervix to block sperm.
Male Condoms: Covering the penis during sexual intercourse to prevent semen entry.
Female Condoms: Covering the vagina to prevent semen entry.
Surgical Methods (Vasectomy or Tubal Ligation): Permanent methods preventing sperm/egg from entering fallopian tubes.
