What's Covered


Today you will be learning about the causes and effects of various sexually transmitted diseases.  Specically you will focus on:

  1. Sexually Transmitted Diseases


1. SEXUALLY TRANSMITTED DISEASES


Sexually transmitted diseases (STDs) are passed by sexual contact with another person and can be caused by parasites, bacteria or viruses. 

Chlamydia is caused by bacteria and is one of the most common sexually transmitted diseases among young people that affects the urinary tract and the genitals. If left untreated, it can actually lead to pelvic inflammatory disease. Chlamydia does not have very obvious warning signs or symptoms, so oftentimes this disease will get left untreated. 

Pelvic inflammatory disease, also known as PID, can be caused by bacteria such as gonorrhea. If either of these two diseases go untreated, they can lead to pelvic inflammatory disease, which can lead to sterility or menstrual problems.

Gonorrhea is another disease that's caused by a bacterium. Diseases that are caused by bacteria can be treated with antibiotics. Sometimes they are hard to detect because the warning signs aren't obvious. Gonorrhea is a bacteria, and in males, it will cause painful urination, oozing from the penis and, if it's left untreated, can cause sterility. In women, the symptoms are very hard to notice and oftentimes it will go untreated, which can then lead to sterility.

Syphilis is also caused by bacteria that causes ulcers or chancres on the skin. Syphilis can affect various organs of your body such as your bones and heart. If left untreated, it can lead to insanity and paralysis. This one, again, can be treated if caught early.

Genital herpes is caused by a virus. There is no cure for genital herpes. Basically, sores will develop on the genitals.

Hepatitis B and Hepatitis C are forms of hepatitis that can be sexually transmitted. Hepatitis B and C are viruses that are transmitted through body fluids, such as blood or semen. This type of virus will attack the liver and inhibit the liver's ability to properly function;  it can be a very serious disease.

Thrichomoniosis is a disease that's caused by a parasite, specifically a protozoan. Thrichomoniosis leads to the urethra becoming inflamed, which can cause painful urination. However, in this disease can be treated with antibiotics.

Genital warts is when warts or growths will develop on the genitals. This is the result of HPV. HPV stands for Human Papilloma Virus. Human Papilloma Virus can lead to the formation genital warts.

Terms to Know

Chlamydia

The most common STD in humans, chlamydia is caused by a
bacterium that infects the reproductive and urinary tracts. If left
untreated it can cause pelvic inflammatory disease.

Pelvic Inflammatory Disease

Inflammation of the uterus, fallopian tubes/oviducts and/or ovaries that can lead to scarring and damage.

Gonorrhea

Commonly referred to as the clap, gonorrhea is a bacterial infection that can cause painful urination and penile discharge in males and vaginal discharge in females.

Syphilis

Caused by bacteria, syphilis initially presents as a rash or skin lesions and if left untreated can cause cardiovascular damage and insanity.

Genital Herpes

A viral infection that can cause sores to develop on the mouth or reproductive organs, genital herpes is an incurable disease.

Hepatitis B

A retroviral infection of the liver that is spread through sexual contact and is very curable in adults.

Thrichomoniosis

A protozoan parasite that commonly causes vaginitis in females.

Genital Warts

Caused by the human papilloma virus (HPV), genital warts appear on reproductive organs and the anus and can increase the chance of developing certain cancers.

Summary

This lesson has been an overview on various sexually transmitted diseases, such as chlamydia, pelvic inflammatory disease, gonorrhea, syphilis, genital herpes, genital warts, hepatitis and trichomoniasis.

Good luck.
