Anal Warts: Risks and Symptoms After Unprotected Sex - Urology

My boyfriend has genital warts in the anal area?


Hello doctor, my boyfriend has been experiencing itching around his anus recently, and yesterday the doctor diagnosed him with anal warts.
We had unprotected intercourse last week, but his penis did not come into contact with my anus during the process.
I went to the gynecologist for a check-up and would like to know if it is possible for symptoms to appear later.
What is the likelihood of transmission if there was no contact with my boyfriend's anus during intercourse?

Hello: Cauliflower is relatively complex; sometimes it is not necessary to directly contact the lesions, as the surrounding skin can also be involved.
The conditions for transmission include immune status and viral load, and it is possible for lesions to appear later.
Wishing you good health.

More Info


Anal warts, commonly known as genital warts, are caused by certain strains of the human papillomavirus (HPV). They can appear in various locations, including the genital area, anus, and surrounding skin. The presence of anal warts can be concerning, especially in the context of recent unprotected sexual activity.
In your case, it is important to understand the transmission dynamics of HPV and the potential risks associated with your recent sexual encounter. HPV is primarily transmitted through direct skin-to-skin contact, which can occur during vaginal, anal, or oral sex. Even if you did not directly touch your boyfriend's anus during intercourse, there is still a risk of transmission if there was any contact with infected areas or bodily fluids. HPV can be present on the skin even if warts are not visible, which complicates the assessment of risk.

Regarding your concern about the possibility of developing symptoms after the sexual encounter, it is indeed possible for HPV to remain dormant in the body for an extended period before symptoms appear. The incubation period for HPV can vary widely, ranging from weeks to months or even years. Therefore, it is plausible that you could develop symptoms related to HPV infection at a later date, even if you do not currently exhibit any signs.

It is also worth noting that while HPV is a common sexually transmitted infection, not all strains lead to the development of warts or other health issues. Some strains are associated with a higher risk of certain cancers, such as cervical cancer in women, while others may cause benign warts. Regular screenings and check-ups with your healthcare provider are essential for monitoring your sexual health and addressing any concerns.

To mitigate the risk of HPV transmission in the future, consider the following preventive measures:
1. Vaccination: The HPV vaccine is highly effective in preventing infections from the most common cancer-causing strains of HPV. It is recommended for both males and females, ideally before the onset of sexual activity.

2. Condom Use: While condoms do not provide complete protection against HPV, they can significantly reduce the risk of transmission. Using condoms consistently and correctly during sexual activity is advisable.

3. Regular Screenings: For women, regular Pap smears and HPV tests are crucial for early detection of any abnormalities that could indicate cervical cancer. Men should also have regular check-ups, especially if they are at higher risk for HPV-related conditions.

4. Communication with Partners: Open discussions about sexual health and STI testing with partners can help reduce anxiety and promote safer sexual practices.

If you have any concerns about your health or potential symptoms, it is essential to consult with a healthcare professional. They can provide personalized advice, conduct necessary tests, and help you understand your risk factors. Remember that early detection and intervention are key to managing any sexually transmitted infections effectively.
