Screening needs vary, but many seniors should test at least once when starting a new relationship, annually if they have more than one partner, and right away after unprotected sex or if symptoms appear, with one-time hepatitis C screening and HIV testing at least once or annually if at risk. Medicare Part B often covers HIV and other STI screening and counseling for people at increased risk with little or no cost when ordered by a Medicare-approved provider, though coverage depends on medical necessity and your plan. There are several factors to consider; see below for specific test intervals, who is considered higher risk, and how to talk with your doctor so you can choose the right next steps.
Sexual health does not end at retirement. Many adults over 65 remain sexually active, form new relationships, or re-enter dating after divorce or the loss of a partner. Yet conversations about sexual health and the frequency of STI testing in older adults are often overlooked. This can lead to delayed diagnosis and treatment of sexually transmitted infections (STIs), which may have more serious consequences with age.
This guide explains how often seniors should consider STI screening, what Medicare typically covers, and how to talk with a doctor about sexual health in a practical, calm, and informed way.
STIs are not limited to younger people. According to data from the U.S. Centers for Disease Control and Prevention (CDC), rates of several STIs—including syphilis, gonorrhea, and chlamydia—have increased among adults aged 55 and older over the past decade.
Several factors contribute to this trend:
STIs in older adults can be more difficult to detect and may worsen existing health problems such as heart disease, diabetes, or weakened immune function. This makes understanding the right frequency of STI testing especially important.
There is no one-size-fits-all schedule. The right frequency of STI testing depends on personal risk factors, sexual activity, and overall health. However, guidance from credible medical organizations such as the CDC and the U.S. Preventive Services Task Force (USPSTF) offers helpful direction.
Seniors should consider STI screening:
For many older adults in long-term, mutually monogamous relationships, routine STI testing may not be necessary unless symptoms develop or a partner's status changes.
Doctors typically recommend different screening intervals depending on the specific infection and risk level.
Early detection is critical. HIV can be managed effectively with treatment, even later in life, but delayed diagnosis increases complications.
Syphilis can affect the brain, heart, and nervous system if untreated, and symptoms may be subtle in older adults.
These infections may cause few or no symptoms yet still lead to complications.
Medicare recognizes the importance of preventive sexual health care and typically covers STI screening when certain conditions are met.
Medicare Part B may cover:
In many cases, these services are covered without cost-sharing when ordered by a healthcare provider and performed by a Medicare-approved provider.
Some seniors feel uncomfortable raising sexual health concerns. However, doctors are trained to discuss these topics professionally and without judgment. Being open helps ensure appropriate care.
When speaking with a doctor, consider discussing:
If something feels serious, unusual, or life-threatening, speak to a doctor right away rather than waiting.
STIs in seniors may not cause obvious symptoms. When symptoms do appear, they can resemble other age-related conditions.
Possible warning signs include:
Prompt testing and treatment can prevent long-term complications and reduce the risk of spreading infections to others.
Sexual health is not only physical. Past or recent experiences can affect how people experience intimacy, make decisions about protection, or seek care. This is true at any age.
If you're experiencing emotional or physical symptoms that may be connected to past experiences, Ubie's free AI-powered Sexual Trauma symptom checker can help you better understand what you're experiencing before speaking with a healthcare provider.
If trauma or distress is affecting your health or safety, speaking to a doctor or mental health professional is strongly recommended.
Maintaining sexual health does not require drastic changes—just informed choices.
Helpful steps include:
These steps support both physical health and peace of mind.
Sexual health remains an important part of overall well-being for seniors. Understanding the right frequency of STI testing, knowing what Medicare covers, and feeling comfortable talking with a doctor can make a meaningful difference.
There is no need for fear or embarrassment—but there is a real need for awareness and timely care. If you have symptoms, concerns, or potential exposure to an STI, speak to a doctor as soon as possible, especially if anything feels serious or life-threatening. Early action protects your health and helps ensure that aging does not mean neglecting an essential part of your well-being.
