Sexually transmitted infections (STIs) are common and often easily treatable, but many people delay testing because symptoms can be subtle, embarrassing, or even absent. Unfortunately, leaving an STI untreated can lead to serious health complications and increase the risk of transmission to others.
This article outlines some of the most common symptoms of STIs in both men and women, highlights when you should seek testing, and explains how easy it is to access STI care through services like Pocket Lab.
Why Recognising STI Symptoms Matters
STIs don’t always cause obvious signs. You might carry and spread an infection without knowing it. This is especially true for conditions like chlamydia and gonorrhoea, which are often silent in the early stages.
Recognising even mild or unusual changes in your body can help you:
Get treatment early, before complications develop
Protect sexual partners
Reduce the risk of spreading the infection
Many people only get tested after a partner is diagnosed or after symptoms have persisted. Being proactive is key to protecting your sexual health.
Common STI Symptoms in Men
While symptoms can vary, some of the most typical signs of an STI in men include:
Pain or burning during urination
Unusual discharge from the penis
Pain or swelling in the testicles
Sores, bumps, or blisters around the genitals or anus
Itching or irritation in the genital area
Painful bowel movements (in some rectal infections)
Some men experience no symptoms at all—especially in the case of chlamydia or HPV. Regular screening is still important if you're sexually active.
Common STI Symptoms in Women
Women may notice signs of infection that overlap with other conditions, such as thrush or urinary tract infections. It’s important not to self-diagnose. See a healthcare provider if you experience:
Unusual vaginal discharge with a strong smell or different colour
Burning during urination
Pain during sex
Lower abdominal or pelvic pain
Itching, soreness, or swelling around the vulva
Sores, ulcers, or bumps in the genital area
Bleeding between periods or after sex
Certain infections like chlamydia, gonorrhoea, and trichomoniasis can lead to pelvic inflammatory disease (PID) if untreated, potentially affecting fertility.
STIs That Often Show No Symptoms
Some of the most commonly diagnosed STIs in New Zealand often go unnoticed until complications arise. These include:
Chlamydia: Often silent but can damage reproductive organs
Gonorrhoea: May cause mild symptoms or none at all
HPV (Human Papillomavirus): Usually no symptoms but can cause genital warts or lead to cervical changes
Hepatitis B: May stay asymptomatic for years
HIV: Early flu-like symptoms may go unnoticed; long-term damage without treatment
This is why routine STI testing is so important, even if you feel healthy.
When to Get an STI Test
You should consider an STI test if:
You have any of the symptoms listed above
A current or former partner tests positive for an STI
You've had unprotected sex with a new partner
You have multiple sexual partners
You’re starting a new relationship and want peace of mind
It’s been over 12 months since your last test
It’s also a good idea to test between partners and to include STI screening as part of your general health routine.
You can book a discreet, STI test online with Pocket Lab, provide samples at your local lab, and get results typically within a few days.
You can also book a STI consultation with a trusted doctor to assess your risk, arrange discreet STI testing, and provide treatment if needed.
How Untreated STIs Can Affect Your Health
Even when symptoms are mild, untreated STIs can lead to long-term issues such as:
Infertility in both men and women
Pelvic inflammatory disease (PID)
Epididymitis (testicle inflammation)
Chronic pelvic pain
Increased risk of contracting or passing on HIV
Liver complications (with hepatitis B)
Some STIs, such as syphilis and HIV, can progress through multiple stages and cause damage to vital organs if not caught early.
Reducing Stigma: Why Early Testing Is Responsible
Many people delay testing due to shame, fear, or not wanting to "make a fuss." But the reality is, STIs are a normal part of sexual health, and getting tested is responsible and respectful to both yourself and others.
Early detection and treatment are the most effective ways to stay healthy and prevent the spread of infections.
