Molluscum Contagiosum in the Genital Area: Symptoms & UK Treatment

Molluscum contagiosum is a viral skin infection caused by a member of the poxvirus family. While it is very common in children (often spread through shared towels or play), in adults, it is frequently classified as a sexually transmitted infection (STI) when it appears on the genitals, groin, or inner thighs. According to NHS guidance, the infection is generally harmless and will eventually clear without treatment, but the process can take many months or even years.

The infection presents as small, firm, dome-shaped spots that are usually 2mm to 5mm in size. They often have a shiny or pearly appearance and a characteristic small indentation or 'dimple' in the centre. While they are usually painless, they can occasionally become red, itchy, or sore if they get irritated or if an inflammatory response begins as the body starts to fight the virus.

In the United Kingdom, many patients initially mistake molluscum for genital warts, skin tags, or even ingrown hairs. However, there are specific features that an online doctor or sexual health clinician will look for:

• The Dimple: Most molluscum bumps have a tiny 'umbilicated' centre.
• Firmness: They feel firm to the touch rather than soft or fleshy.
• Location: When spread sexually, they typically appear on the penis, scrotum, vulva, pubic mound, or inner thighs.
• Grouping: The spots often appear in small clusters.

It is important to remember that if you have these spots in the genital area, you should seek a formal diagnosis. This ensures you are not living with a different STI, such as Syphilis or Genital Warts (HPV), which may require different management strategies under NICE clinical knowledge summaries.

The virus lives only in the top layer of the skin and does not enter the bloodstream. It is spread through direct skin-to-skin contact or by 'fomites'—objects that have touched the virus, such as towels, flannels, or razors. In adults, sexual contact is the most common route of transmission for genital cases.

To prevent spreading the infection to other parts of your body or to other people, follow these precautions:

• Do not shave or wax: Shaving causes micro-tears in the skin, allowing the virus to spread rapidly to adjacent areas. This is a common cause of 'outbreaks' in the pubic region.
• Avoid scratching: Picking or scratching the bumps can cause them to bleed and release the viral core, which is highly infectious.
• Use separate towels: Do not share towels or cloths with others in your household.
• Barrier protection: While condoms can reduce the risk, they may not cover all affected skin, meaning transmission is still possible during intimate contact.

In the UK, the standard NHS approach is often to 'wait and see,' as the virus is self-limiting. However, many patients prefer treatment for cosmetic reasons or to reduce the risk of transmission to a partner. Treatment options include:

Topical Treatments

Certain liquids or creams can be applied directly to the spots to encourage the immune system to react. Some of these are available via a prescription from an online doctor after a consultation.

Cryotherapy

This involves freezing the bumps with liquid nitrogen. It is usually performed in a GP surgery or a sexual health clinic. Multiple sessions may be required if the spots are numerous.

Curettage or Expression

A clinician may use a small surgical instrument to scrape the bump away or 'pop' the central core. Do not attempt this at home, as it can lead to scarring and secondary bacterial infections.

If you have noticed new bumps in your genital area, it is natural to feel anxious. Speaking to an online doctor in the UK is a convenient and confidential way to get a professional opinion. You should book a consultation if:

• You are unsure if the bumps are molluscum, warts, or another condition.
• The spots are spreading rapidly across the groin or abdomen.
• The bumps are becoming red, painful, or discharging pus (which may indicate a secondary infection).
• The presence of the spots is causing significant psychological distress or affecting your intimate relationships.
• You have a weakened immune system, as molluscum can be more persistent and extensive in these cases.

An online GP can review your symptoms, provide advice on self-care, and, where appropriate, suggest treatments or refer you to a local specialist clinic for physical intervention like cryotherapy.

The good news is that molluscum contagiosum does not stay in your system forever. Once the spots have cleared, the virus is gone, and you are no longer contagious. Most cases in healthy adults resolve within 6 to 12 months, though some may persist longer. It does not affect your long-term fertility or general health. If you are diagnosed with genital molluscum, it is often recommended to have a full STI screen to ensure no other underlying infections were transmitted at the same time.
