Finding an unexpected lump, bump, or spot in the genital area can understandably cause anxiety. Many people worry that a new change may be a sign of a sexually transmitted infection (STI), such as genital herpes. In reality, many genital skin changes are normal, harmless anatomical variations.
One of the most common areas of confusion we see in clinic is distinguishing between Fordyce spots and genital herpes. Although they can appear in similar areas, they are fundamentally different in cause, symptoms, and management. This guide aims to help you understand the key differences and recognise when specialist advice is appropriate.
Fordyce spots are small, raised, painless bumps that can appear on the shaft of the penis, the scrotum, or the labia. They represent ectopic sebaceous (oil) glands — the same type of glands that normally moisturise skin and hair, but located on hairless or mucosal surfaces.
Key features of Fordyce spots:
- Appearance: Small (approximately 1–3 mm), yellowish-white or flesh-coloured
- Sensation: Not painful and does not itch
- Contagion: Not infectious and cannot be passed to a partner
- Prevalence: Very common, seen in up to 70–80% of adults
Fordyce spots are a normal part of human anatomy. They do not pose a health risk and usually remain stable over time. Some people, however, find their appearance distressing or cosmetically bothersome.
Genital herpes is a common STI caused by the herpes simplex virus (HSV). Unlike Fordyce spots, herpes is an infection and typically presents in episodes (outbreaks).
Key features of genital herpes:
- Appearance: Early outbreaks often start as small red bumps or fluid-filled blisters, which may burst and form painful sores or ulcers that then crust over
- Sensation: Frequently associated with tingling, itching, burning, or pain
- Systemic symptoms: Some people experience flu-like symptoms (fever, aches, swollen glands), particularly during a first episode
- Contagion: Highly contagious through skin-to-skin contact, including sexual contact
Herpes lesions change over time and usually heal within a few weeks, although the virus remains in the body and can reactivate.
Fordyce Spots vs Herpes: Key Differences at a Glance
When trying to distinguish between Fordyce spots and herpes, it helps to look at how the spots behave over time:
| Feature |
Fordyce Spots |
Genital Herpes |
| Pain/Itching |
None |
Often painful, itchy, or tender |
| Appearance |
Small (1-3mm), white/yellow bumps |
Blisters, crusting, or open sores |
| Fluid |
Solid (no fluid) |
Blisters contain clear or cloudy fluid |
| Duration |
Permanent unless treated |
Outbreaks heal within 1–3 weeks |
| Contagiousness |
Not contagious |
Can be transmitted to partners |
Why an accurate diagnosis matters
Although self-examination is helpful, genital skin changes can be difficult to interpret without clinical experience. Anxiety around herpes is very common, and misidentifying normal skin features can cause unnecessary distress and impact sexual wellbeing.
A professional assessment allows us to:
- Confirm whether lesions are benign anatomical variants
- Identify infections that require treatment
- Provide reassurance and clear guidance on next steps
Testing for Herpes
If an infection is suspected, we offer appropriate diagnostic testing:
- Herpes DNA PCR swab
This is the most accurate test when a blister or sore is present. A swab is taken directly from the lesion to detect the virus.
- Herpes antibody blood test
This test looks for antibodies, showing whether your immune system has been exposed to HSV in the past. It can be useful in selected situations but does not always explain current symptoms.
Your clinician will advise which test, if any, is appropriate for you.
Managing Fordyce Spots
Fordyce spots do not require treatment for medical reasons. However, if they cause distress or affect confidence, we offer specialist removal using hyfrecation.
Hyfrecation is a precise, low-power electrical technique used in genital dermatology to treat superficial skin lesions.
What the process involves:
- Preparation: Local anaesthetic is used (numbing cream or small injection)
- Procedure: Each spot is treated individually with minimal impact on surrounding skin
- Aftercare: You receive a tailored aftercare pack and clear written instructions to support healing
A face-to-face examination is always required before treatment to confirm the diagnosis and discuss risks and expectations.
Your Journey with Us
We aim to make sexual health care accessible, discreet, and supportive:
- Initial assessment
Secure pre-appointment questionnaires and photographs may allow an initial opinion, but do not replace in-person examination.
- In-clinic care
Where examination, testing, or treatment is needed, this is provided in a professional and confidential setting.
- Ongoing support
From STI testing to post-procedure follow-up, we support you until you feel informed and reassured.
