The Rise of STIs in London: What Tests Should You Get in 2025?

Sexually transmitted infections (STIs) are on the rise across the UK, with London seeing the sharpest increase. According to recent public health reports, diagnoses of gonorrhoea, syphilis, and chlamydia are at record levels, and emerging infections such as trichomonas and Mycoplasma genitalium are being detected more frequently.

If you are sexually active, discreet and accurate testing is essential to protect both your health and that of your partner. At Marylebone Diagnostic Centre, 73 Baker Street, W1U 6RD, we provide fast, confidential STD testing in London, from single tests to comprehensive sexual health panels.

Why Are STIs Rising in London?

London has always been at the centre of healthcare trends, and unfortunately STIs are no exception. Several factors are driving the surge:

• Increased casual relationships and dating app use.
• Lower condom uses across younger age groups.
• Drug-resistant infections, especially antibiotic-resistant gonorrhoea.
• Lack of symptoms in many people, meaning infections spread unknowingly.

The rise is not limited to traditional infections such as gonorrhoea or chlamydia. We are seeing growing awareness of conditions like trichomoniasis and Mycoplasma genitalium, which are often overlooked but can cause long-term reproductive health problems.

The Most Common STIs in 2025

1. Chlamydia

Still the most common STI in London. Often symptomless, but it can cause pelvic inflammatory disease and infertility if untreated.

2. Gonorrhoea

Cases have risen sharply in the last five years. Resistant strains are now a major concern.

3. Syphilis

Rates are at their highest in decades. Untreated, syphilis can cause severe long-term complications.

4. Trichomonas

An underdiagnosed STI that affects both men and women. Symptoms include discharge and discomfort, but many carriers show no signs.

5. Mycoplasma genitalium

A bacterial infection linked to infertility and pelvic pain. Testing is now recommended in comprehensive sexual health panels.

What Tests Should You Get in 2025?

At MDC, we recommend a personalised approach to sexual health testing. Our most popular packages include:

• Basic STI Panel – covers the most common infections such as HIV, syphilis, gonorrhoea, and chlamydia.
• Advanced Sexual Health Panel – includes additional tests for Mycoplasma genitalium, Ureaplasma, Trichomonas, and hepatitis viruses.
• Targeted Testing – if you are worried about a specific exposure, we can test for one or more infections.

Why Early Testing Matters

Many STIs do not cause noticeable symptoms. Without testing, they can silently damage reproductive health and increase the risk of complications such as infertility, pelvic inflammatory disease, or chronic pain. Early detection ensures:

• Faster treatment and recovery.
• Reduced risk of transmission.
• Protection of long-term fertility and health.
