Human Reproduction, Sexual Health, and Disease Prevention

Sexual Maturity and the Stages of Life

Changes in sexual maturity occur throughout the stages of infancy, puberty, adolescence, and adulthood.

Labor and Childbirth

Labor: This process involves dilation, expulsion, and childbirth.

Complications: Potential issues include poor posture of the baby, insufficient dilation of the cervix of the uterus, and umbilical cord pinching.

Infertility and Assisted Reproduction

Sterility: This is defined as the inability to have children.

• Male: Causes include insufficient sperm production, immature spermatozoa, mobility issues, or malformations.
• Female: Causes include obstruction of the Fallopian tubes, lack of ovulation due to hormonal imbalances, or difficulty in the implantation of the zygote in the endometrium.

Assisted Reproductive Techniques: These include artificial insemination and in vitro fertilization.

Alternative Contraceptive Methods

• Natural: The Ogino-Knaus method, monitoring basal body temperature, and the observation of cervical mucus.
• Mechanical: Male and female condoms, the diaphragm, and the IUD.
• Chemical: Spermicides and contraceptive pills.
• Surgical: Tubal ligation and vasectomy.

Sexual Habits and Definitions

Sexual Habits: Maintain health by washing frequently, using condoms, avoiding promiscuity, and avoiding violent attitudes. It is important to seek a trusted adult interlocutor, see your doctor, and ignore advice from uninformed persons.

Sex: The biological condition by which individuals are distinguished as male or female.

Sexuality: A set of anatomical, physiological, and psychological conditions that characterize each sex, representing a series of emotional phenomena and behaviors related to sex.

Health and Infectious Diseases

Health is a state of complete physical, mental, and social well-being. Diseases can be categorized as physical, social, or mental.

Infectious Diseases and Transmission

Infectious Diseases: These can be transmitted through the air, by means of any contaminated object, through physical contact (STDs), or by the ingestion of contaminated food.

Infectious Agents: The primary causes of diseases are fungi, protozoa, bacteria, and viruses.

Sexually Transmitted Diseases (STDs)

• Candidiasis: Caused by a fungus.
• Gonorrhea: Caused by bacteria.
• Syphilis: Caused by bacteria.
• Genital Herpes: Caused by a virus.
• Hepatitis B and C: Caused by a virus.
• AIDS: Caused by a virus.

Treatments and Non-Infectious Diseases

Treatments: Fungi are treated with fungicides, bacteria with antibiotics, protozoa with specific chemical substances, and viruses with antibodies.

Non-Infectious Diseases: These include metabolic, genetic, degenerative, and autoimmune diseases, as well as those caused by cellular proliferation.

Prevention and Donation

Disease Prevention: It is essential to take prophylactic measures to avoid risk factors and adopt healthy habits.

Donation: The donation of cells, tissues, and organs is vital, though one must consider the risks of rejection or infection.
