Sexually transmitted diseases (STDs) are infections spread primarily through unprotected sexual contact. They affect millions of people worldwide, and men are no exception. Many STDs may be asymptomatic at first, but if left untreated, they can lead to serious complications, such as infertility, chronic pain, and even increase the risk of contracting other infections like HIV.
In this article, we'll discuss what STIs are, how they're transmitted, which are the most common in men, their symptoms, diagnosis, treatment, prevention, and answer the most frequently asked questions on the topic.

What are STIs?
Sexually transmitted diseases (STDs), also known as sexually transmitted infections (STIs), are a group of infections caused by bacteria, viruses, fungi, or parasites that are spread primarily through unprotected sexual contact. These infections can affect the genitals, rectum, mouth, and, in some cases, other organs of the body.
The causative agents include bacteria, which are responsible for infections such as chlamydia, gonorrhea, and syphilis. These are usually curable with antibiotics if detected early; viruses, which include HIV, genital herpes, HPV, and hepatitis B and C. Some are incurable but can be controlled with medication; parasites such as Trichomonas vaginalis, which causes trichomoniasis and is treatable with antiparasitic drugs; and fungi. Although less common, some yeast infections can be sexually transmitted.
They are a public health problem, as many STIs are asymptomatic in their early stages, which makes it easy for them to spread without the person even knowing they are infected. Some, such as HPV and hepatitis B, are linked to cancer (cervical, penile, liver, etc.). And others, such as untreated syphilis, can cause serious neurological and cardiovascular damage.
How are they transmitted?
STIs are primarily spread through sexual contact, but not all require penetration. The main routes of transmission are unprotected sexual contact, whether vaginal, anal, or oral, without a condom. Some diseases, such as herpes and HPV, are transmitted through skin-to-skin contact, even without ejaculation.
They can also be transmitted through the exchange of bodily fluids, such as semen, vaginal secretions, and blood, which can transmit HIV, hepatitis B and C, and other infections. Oral sex can also transmit gonorrhea, chlamydia, and syphilis.
They can be contracted through blood by sharing needles (injectable drugs, tattoos, or unsterilized piercings) or through untested blood transfusions (in countries with poor health controls).
In addition, vertical transmission (from mother to child) can occur during pregnancy, childbirth or breastfeeding, with diseases such as HIV, syphilis or herpes.
However, some practices that are thought to transmit STIs but do not include casual contact (hugging, social kissing) and sharing food or drinks (except in very rare cases of active oral herpes). They are also not transmitted by insect bites.
What are the most common STDs in men?
Chlamydia
Caused by the bacteria Chlamydia trachomatis, is one of the most common STIs. Many men don't experience symptoms, but when they do, they can include urethral discharge, painful urination, and testicular pain. If left untreated, it can cause infertility.
Gonorrhea
La gonorrhea in men It is produced by the bacteria Neisseria gonorrhoeae, can infect the urethra, rectum, or throat. Common symptoms include white, yellow, or green discharge from the penis, pain when urinating, and pain in the testicles.
In severe cases, it can spread to other parts of the body and cause arthritis or male infertility.
Syphilis
Caused by the bacteria Treponema pallidum, has several stages.
Primary: Appearance of a painless ulcer (chancre) on the penis, anus, or mouth. Secondary: Skin rash, fever, and swollen glands. Tertiary: Can affect the brain, heart, and other organs if left untreated.
VIH / PAGE
The Human Immunodeficiency Virus (HIV) attacks the immune system. Without treatment, it progresses to AIDS. Initial symptoms may include fever, fatigue, and swollen glands.
Genital Herpes
Caused by the herpes simplex virus (HSV-2), it causes painful blisters in the genital area. There's no cure, but antivirals help control outbreaks.
Human Papillomavirus (HPV)
Some strains cause genital warts, while others are associated with cancer of the penis, anus, or throat. There is a vaccine to prevent this.
Hepatitis B and C
They affect the liver and are transmitted through sexual contact or contaminated blood. They can become chronic and cause cirrhosis or liver cancer.
How to know if a man has an STD?

Tests and diagnosis
STIs can be detected through blood tests (HIV, syphilis, hepatitis), urine or secretion samples (chlamydia, gonorrhea), or physical examination (herpes, HPV).

How to treat an STD in men?
Treatment varies depending on the type of infection. It's essential not to self-medicate and to follow a doctor's instructions.
For bacterial infections (Chlamydia, gonorrhea, syphilis), antibiotics are the primary treatment. It is essential to complete the treatment even if symptoms disappear, avoid sexual intercourse until a doctor confirms a cure, and notify sexual partners so they can also be treated.
In the case of viral infections, HIV has no cure, but antiretroviral drugs (ART) control the virus and prevent AIDS. For herpes, acyclovir or valacyclovir reduce outbreaks but do not eliminate the virus. There is no treatment for HPV, but warts can be removed with cryotherapy or laser. Hepatitis B and C are treated with antivirals such as tenofovir (hepatitis B) or sofosbuvir (hepatitis C).
Parasitic infections (Trichomoniasis) are treated with metronidazole or tinidazole (antiparasitic medications).
What happens if I don't treat an STD in time?
If left untreated, STIs can cause problems such as infertility (due to blocked seminal ducts in chlamydia/gonorrhea), chronic pelvic pain, increased risk of HIV (genital ulcers facilitate transmission), or serious complications (tertiary syphilis, HPV cancer, cirrhosis due to hepatitis).
How to prevent STIs in men?
Correct use of condoms
A condom (male or female) should always be used in vaginal, anal and oral sex.verify its expiration date and store it in a cool place. Nor reuse nor use two condoms at the same time.
Vaccination
For HPV, the vaccine (Gardasil) protects against the most dangerous strains (6, 11, 16, 18). It is recommended for men up to age 26. For hepatitis B, three doses provide lifelong protection.
Periodic tests
Get tested at least once a year if you are sexually active and additional tests if you have multiple partners or unprotected sex.
Risk reduction
Limit the number of sexual partners. Avoid alcohol and drug use in sexual contexts (they impair judgment and increase risky behaviors). And don't share needles or personal items (such as razors).
Sex education
STIs and protection should be discussed openly with partners, and symptoms should be known to detect infections early.
