“Postmenopausal women are especially vulnerable to STIs
because having fragile vulvar tissues
can allow these viruses to enter the body more easily”.1

Umbrella

What may the Sexually Transmitted Infections Umbrella include?

Depending on the Source (DotS) this Umbrella may include:

  • Sexually Transmitted Diseases (STDs)
  • Sexually Transmitted Infections (STIs)
  • Venereal Diseases (VD)

Terminology

Are sexually transmitted infections (STIs) also called sexually transmitted diseases (STDs)?

In Sexually Transmitted Infections the Office on Women’s Health, United States Department of Health and Human Services, Womenshealth.gov explain:

“Sexually transmitted infections (STIs) are also called sexually transmitted diseases, or STDs”.2

Sexually Transmitted Infections

What are sexually transmitted infections (STIs)?

DotS the definition of STIs may vary. The (Australian) Jean Hailes for Women’s Health’s (JH) definition is:

“An STI is an infection spread from one person to another usually during sex. STIs can be spread through semen, vaginal fluids, anal fluids, blood, skin-to-skin contact and, in some cases, saliva”.3

Sexually Transmitted Diseases

What are sexually transmitted diseases (STDs)?

DotS the definition of STDs may vary. The (United States) MedlinePlus’ definition is:

“Sexually transmitted infections (STIs), or sexually transmitted diseases (STDs), are infections that are passed from one person to another through sexual contact. They are usually spread during vaginal, oral, or anal sex. But sometimes they can spread through other sexual contact involving the penis, vagina, mouth, or anus. This is because some STIs, like herpes and HPV, are spread by skin-to-skin contact”.4

How Many

How many STIs are there?

In Sexually Transmitted Infections (STIs): Overview the World Health Organization (WHO) elaborate on:

“More than 30 different bacteria, viruses and parasites are known to be transmitted through sexual contact, including vaginal, anal and oral sex. Some STIs can also be transmitted from mother-to-child during pregnancy, childbirth and breastfeeding. Eight pathogens are linked to the greatest incidence of STIs. Of these, 4 are currently curable: syphilis, gonorrhoea, chlamydia and trichomoniasis. The other 4 are viral infections: hepatitis B, herpes simplex virus (HSV), HIV and human papillomavirus (HPV)”.5

Cause

What can cause STIs?

In Sexually Transmitted Diseases (STDs): Symptoms & Causes – Causes the (United States) Mayo Clinic note:

“Sexually transmitted infections can be caused by:

  • Bacteria.  Gonorrhea, syphilis and chlamydia are examples of STIs that are caused by bacteria
  • Parasites. Trichomoniasis is an STD caused by a parasite
  • Viruses. STDs caused by viruses include human papillomavirus (HPV), the herpes simplex virus, and the human immunodeficiency virus (HIV), which causes AIDS”.6

Human Papillomavirus Virus

What is the human papillomavirus (HPV)?

In Sexually Transmitted Infections (STIs): About Genital HPV Infection – Overview: What Is Human Papillomavirus (HPV)? the (United States) Centers for Disease Control and Prevention (CDC) explain:

“HPV is the most common STI. There are many different types of HPV. While most do not cause any health problems, some types can cause genital warts and cancers. Vaccines can stop these health problems from happening. HPV is a different virus than HIV and HSV (herpes)”.7

In Sexually Transmitted Infections (STIs): Key Facts, dated 21 May 2024, the WHO note:


  • “Human papillomavirus (HPV) infection is associated with over 311 000 cervical cancer deaths each year”.8

Common or Not

How common are STIs?

In Sexually Transmitted Infections (STIs): Key Facts, dated 21 May 2024, the WHO note:

  • “More than 1 million curable sexually transmitted infections (STIs) are acquired every day worldwide in people 15–49 years old, the majority of which are asymptomatic”.9

Risk

Who can catch an STI?

In Safer Sex and Sexually Transmitted Infections (STIs): How To Have Safer Sex the JH explain:

“Practising safer sex can reduce your risk of getting an STI. Anyone can catch an STI. You can’t tell if a sexual partner has an STI. A strong and healthy person may still be infected. Some people may not even know they have an STI.

It’s important to communicate openly and agree on protection before you have sex”.10

Oral Sex

Does oral sex reduce the risk of getting an STI?

According to the JH:

“Note that oral sex doesn’t reduce the risk of getting an STI. Common STIs such as herpes, gonorrhoea and chlamydia can all be transmitted through unprotected oral sex”.11

Perimenopause and Menopause

During perimenopause and following menopause, is it still possible to acquire STIs?

In Sexual Health: Practice Safe Sex the Menopause Society (formerly the North American Menopause Society) note:


“Sexuality doesn’t—and shouldn’t—end with menopause. Still, even with advancing age, safe sex is critical. After menopause and without the risk of pregnancy, it’s easy to let protected sex slide. But anyone who is not in a long-term, monogamous relationship and has unprotected sex is at risk of sexually transmitted infections (STIs). You need to be aware of the many infections you can get and take the necessary precautions. Postmenopausal women are especially vulnerable to STIs because having fragile vulvar tissues can allow these viruses to enter the body more easily”.12

In Sexually Transmitted Infections (STIs): Changes Associated With Menopause the WHO explain:

“During perimenopause and following menopause, it is still possible to acquire sexually transmitted infections (STIs), including HIV, through unprotected sexual contact, including oral, anal and vaginal sex. The thinning of the vaginal wall after menopause increases the chances of lesions and tears, thereby increasing the risk of HIV transmission during vaginal sex”.13

Safer Sex

What is safer sex?

DotS the definition of safer sex may vary. In Safer Sex and Sexually Transmitted Infections (STIs): Safer Sex the JH’s definition includes:

“Safer sex is not just about protection from unplanned pregnancies and sexually transmitted infections (STIs). It’s also about making sure everyone involved feels safe and respected.

Communication is an important part of safer sex. Whether you’re in a long-term relationship or an open relationship with multiple partners, it’s important to talk about consent, contraception and sexual preferences before you have sex. This is also a good time talk about things like boundaries and STIs”.14

Female Condom

What is a female condom?

DotS the definition of a female condom may vary. In Contraception: Coitally-Dependent Barrier Methods — (c) Female Condom the Australasian Menopause Society explain:

“The female condom is a polyurethane sheath inserted into the vagina prior to intercourse. It is less commonly used than other forms of contraception. They are more expensive than male condoms and have a slightly higher failure rate. They can be purchased online at family planning clinics and also at some pharmacies”.15

In Internal Female Condoms the (United Kingdom) NHS also explain what female condoms are.

Testing

Where may STIs testing be available?

DotC (Depending on the Country) STIs testing may be available from your health care provider or your country’s equivalent of a:

  • Family Planning Center/Clinic
  • Genitourinary Medicine Center/Clinic
  • Sexual Health Center/Clinic
  • Women’s Community Health Center/Clinic
  • Women’s Contraceptive Center/Clinic
  • Women’s Health Center/Clinic

Pap Test

Does a Pap test screen for STIs?

In Sexually Transmitted Infections: Does A Pap Test Screen for STIs? Womenshealth.gov explain:

“No. Pap testing is mainly used to look for cell changes that could be cancer or precancer. However, your doctor may test you for HPV in addition to doing the Pap test if you are older than 30.

If you want to be tested for STIs, you must ask your doctor or nurse”.16

Health Care Provider

What if I would like help with safer sex and/or female condoms?

If you would like help with safer sex and/or female condoms it may be in your best interest to choose to talk to your health care provider about this.

In Safer Sex and Sexually Transmitted Infections (STIs): What To Do If You Have An STI the JH also explains:

“If you are diagnosed with an STI, it’s important to follow the treatment recommended by your doctor. Take the full course of medicines even if you start to feel better and symptoms disappear.

It’s also important to tell anyone you’ve recently had sexual contact with so they can be tested and treated too.

If you find this hard, the following websites have tips on how to tell your partner and ways you can send an SMS or text without them knowing it’s from you:
