What's really behind erectile dysfunction.
ED is common, treatable, and rarely about one thing. It usually comes down to blood flow, but hormones, stress, health, and habits all factor in. Understanding the why is how a clinician chooses the right treatment, instead of guessing.
Blood flow
An erection is a circulation event. When blood vessels don't relax and fill the way they should, firmness suffers. It's the most common mechanism behind ED.
Hormones
Low testosterone can lower desire and affect erections. When it fits the picture, a clinician may check your levels rather than treat the symptom alone.
The mind
Stress, anxiety, depression, and performance pressure are real physical drivers. A reliable option often takes the pressure off and breaks the cycle.
Lifestyle
Sleep, alcohol, smoking, and inactivity all move the needle. Small changes alongside treatment tend to compound over time.
Health and medications
Diabetes, blood pressure, and certain prescriptions can contribute. Your history matters, which is why a clinician reviews it before anything is prescribed.
A possible early signal
Because ED is vascular, it can be an early sign of cardiovascular or metabolic issues worth checking. Treating it is also a reason to look at the bigger picture.
A licensed clinician reviews your history and, when it's warranted, your bloodwork before recommending treatment. If your symptoms point somewhere else, they'll tell you, and help you find the right path.

How treatment actually helps.
Support healthy blood flow
The medications a clinician may prescribe relax blood vessels so that, when you're aroused, your body produces a firmer, more reliable response. They support your natural response, they don't replace arousal.
Match the format to your life
As-needed for spontaneity on demand, a low daily dose for readiness without planning, or a compounded fast-dissolve option. Your provider helps you find the format and strength that fit how you actually live.
Address the root when it's there
If hormones, health, or another factor is driving things, a pill alone isn't the answer. A licensed clinician can check testosterone and related markers and treat the cause, not just the moment.
Options a provider may consider for you.
Sildenafil
A well-studied option that supports blood flow for an as-needed, on-demand response. Taken before intimacy.
Tadalafil (daily)
A low daily dose that supports readiness without timing around a single dose, for more spontaneity.
Tadalafil (as-needed)
A longer-acting option taken before intimacy, with a wider window than sildenafil for some men.
Sildenafil / Tadalafil combo
A compounded, fast-dissolve option that pairs ingredients when a clinician determines it's appropriate.
Hormone evaluation
When low desire or other signs fit, a clinician may check testosterone and related markers to treat an underlying cause.
Lifestyle and follow-up
Sleep, alcohol, training, and ongoing provider support that help treatment work and last.
Which option is appropriate, and at what strength, is a clinical decision your provider makes from your history and goals. Some products are compounded, are not FDA-approved, and require a prescription. Individual results vary.
Why men choose KAYU for sexual health.
A real clinician, on video
You speak face to face with a licensed clinician before anything is prescribed. Not a chatbot, not a one-way questionnaire.
Built for you, compounded
Your provider chooses the ingredient, strength, and format compounded by a licensed pharmacy, instead of a single off-the-shelf pill.
Discreet by default
The whole process is online and private, and your formula ships free in plain, unmarked packaging. No waiting rooms, no awkward conversations.
We look for the why
ED can point to hormones or heart health. A clinician reviews the bigger picture and checks labs when it's warranted, rather than just handing you a pill.
Transparent pricing
You pay for care. If a treatment is prescribed, the pharmacy bills medication separately at cost, with no KAYU markup.
Safety first
These medications aren't right for everyone, especially with certain heart conditions or nitrate medications. A clinician reviews your history and declines when it isn't safe.
A realistic timeline.
Your provider explains how and when to take your treatment and what to expect. The first attempt is a starting point, not the final verdict, and settings often need a small adjustment.
Based on how it worked and how you felt, your provider can adjust the strength, switch the ingredient, or change the format until it fits how you want to use it.
Refills, check-ins, and secure messaging keep things on track. If an underlying cause turns up, your provider helps you address it over time.
Timelines are general and not a promise of results. Individual results vary, and your provider adjusts your treatment with you along the way.
When it works, and how long it lasts.
Two proven options with very different timing. Your clinician helps you pick the one that fits how you actually want it to work.
Timing reflects typical clinical ranges; onset and duration vary by person, dose, and food. Compounded and prescription-only, after a licensed clinician reviews your history.
Real clinicians, not a call center.
Your protocol is built and monitored by a licensed clinician, the same people who designed KAYU's care model. Named, credentialed, and accountable for your results.

Men's sexual health FAQ.
What causes erectile dysfunction?
ED usually comes down to blood flow, but hormones, stress and anxiety, sleep, alcohol, certain medications, and conditions like diabetes or high blood pressure all play a part. Because it's so common and the causes overlap, a licensed clinician reviews your history to find what's actually driving it for you.
Is erectile dysfunction actually common?
Yes, very. Difficulty getting or keeping an erection affects a large share of men at some point, and it becomes more common with age. It can also show up with stress, sleep, relationships, or other health factors. You're far from alone, and it's one of the most treatable things men come to a provider for.
Does treatment actually work?
The medications KAYU clinicians prescribe are well-studied and widely used to support blood flow for a firmer, more reliable response when you're aroused. No treatment works for everyone, and the right option depends on your health, which is why a licensed clinician reviews whether it's appropriate for you first. Individual results vary.
What's the difference between sildenafil and tadalafil?
Sildenafil is typically taken as-needed before intimacy and acts over a shorter window. Tadalafil lasts longer and comes as either an as-needed dose or a low daily dose that supports readiness without planning around timing. Your provider helps you choose based on how you want to use it and your health.
Is ED a sign of something more serious?
It can be. Because erections depend on healthy blood vessels, ED is sometimes an early signal of cardiovascular or metabolic issues. That's part of why a clinician looks at the bigger picture and may recommend bloodwork, rather than only treating the symptom.
Is it safe?
A licensed clinician reviews your health history before anything is prescribed and declines or adjusts treatment if it isn't appropriate for you. These medications aren't right for everyone, especially with certain heart conditions or if you take nitrate medications, where combining them can be dangerous. Your provider reviews potential side effects with you.
Is it discreet and private?
Yes. The entire process happens online, your assessment is private, and your formula ships free in plain, unmarked packaging. There are no waiting rooms and no awkward conversations, just your provider and your care team, on your schedule.
How does billing work, and do you take insurance or HSA / FSA?
You pay for your provider review and care. If a treatment is prescribed, the pharmacy bills for your medication separately, at cost, with no KAYU markup. No insurance is required, and many patients use HSA or FSA funds toward eligible care. You're only charged for medication after a licensed clinician approves it.
Can I cancel anytime?
Yes. There's no long-term commitment. You can adjust, pause, or cancel your care anytime, and your provider and care team are reachable by secure message whenever you have questions.
Ready to feel rooted?
Two minutes to the assessment. One week to your first consult. A protocol built on your bloodwork from a provider who knows your name.
