Why insist on morning testosterone before any price talk?
Start with the story, not a milligram
Start with the story, not with a milligram. When did it change - slowly over years, or in a week? Do morning erections still arrive? Is desire gone, or is desire present and the rigidity missing? Has a partner change, a surgery, or a new medicine landed on the same calendar?
A tablet cannot answer those questions. A 10 mg Cialis card, a 25 mg diamond, or a Levitra 2.5-or-20 mark all assume there is enough nerve, enough vessel, and enough hormone for cGMP to matter. If the failure is a blocked artery, a cut nerve, a testosterone under 300 ng/dL with symptoms, or a panic that starts before any touch, the first card may be a lab, a cardiology look, or a therapist - not a blister.
This page will not rank molecules. The match file already refused a crown. Here we bind the work-up the AUA expects before anyone talks price.
The psych layer that a tablet cannot hear
Situational failure - rigid on waking, blank with a partner - is a classic psychogenic or mixed pattern. Performance fear writes a loop: one bad evening, then watching, then another blank. A PDE5 can sometimes break the loop by giving a reliable first success. It cannot hear a couple who have stopped touching for a year.
Depression, anxiety, and many of the medicines used to treat them sit on both sides of the ledger. SSRIs are famous for blunting desire and delaying orgasm. Naming the medicine is part of the work-up. Stopping it in the parking lot is not.
Alcohol and other sedating drugs deserve a plain sentence. A man who only fails after a bottle is not first in line for a 20 mg ceiling. He is first in line for an honest count of drinks. The tablet will not outrun a Saturday night that already chose a depressant.
When a PDE5 is the wrong first card
A nitrate still in the pocket. Unstable coronary disease. A cardiologist who already said sex is unsafe. Those are hard stops, not 'start low' situations. The origin file exists because that collision was measured.
Documented hypogonadism with symptoms, especially collapsed desire, may need a testosterone plan alongside or before a PDE5. The AUA notes that in men with testosterone deficiency who are considering a PDE5, the inhibitor may work better when testosterone is also treated. That is combination counseling, not a license to skip the draw.
Primary psychogenic ED in a young man with intact morning erections may need a skilled sex-therapy hour more than a 20 mg ceiling. Peyronie's disease with pain and a bend needs a urology look. Priapism history needs a different caution set. Pelvic trauma in a young man is a specialist file. None of those is solved by asking which of three cards 'wins.'
Vascular plumbing that will not fill
Most later-life ED is endothelial. The same arteries that feed the heart feed the penis, only the penile ones declare the problem earlier. Smoking, diabetes, hypertension, high lipids, obesity, and a couch habit are not 'lifestyle colour.' They are the plumbing list.
A man who gets winded on a flight of stairs is telling you the heart may not tolerate the work of sex. Princeton-style risk banding still matters: stabilize high-risk disease before anyone inks a PDE5. The tablet does not replace a stress test you already needed.
ED can be the first public sign of atherosclerotic disease. Treating only the erection and ignoring fasting glucose, A1c, and a lipid panel is how a 'simple pill visit' misses the myocardial infarction two years later. Name the vessels. Then decide whether a tablet is even safe.
Weight, sleep apnea, and tobacco are not moral footnotes. They change endothelial function. A man who wants a tablet and will not discuss those is still allowed a work-up. He is not allowed to pretend the vessels are a mystery the blister will solve. Name what can be changed. Then, if a PDE5 is still the right remainder, pick a card.
Tests that belong on the slip first
| On the slip first | Why it sits there | What it is not |
|---|---|---|
| Story + medicine list | Sorts sudden vs slow, situational vs global | Not a reason to skip labs |
| Morning total testosterone | AUA: measure in men with ED | Not an ED treatment if T is already normal |
| A1c / fasting glucose, lipids | Vascular risk often is the disease | Not optional 'if we have time' |
| Heart-risk banding | Sex is work; high-risk disease waits | Not a PDE5 allergy test |
| Special vascular / nerve tests | Young, trauma, surgery planning | Not a first-visit default |
History and medicines first. Then a blood-pressure check and a look at pulses if the story is vascular. Morning total testosterone. Fasting glucose or A1c. A lipid panel when cardiovascular risk has not been recently named. Those are ordinary, cheap, and more useful than a boutique scan on visit one.
Special vascular or neurologic testing is for the odd case: a young man after pelvic trauma, a failure that makes no sense, a man heading toward surgery. Nocturnal erection studies exist. They are not a default shopping item.
Shared decision-making in the AUA guideline assumes the man has heard the options - oral PDE5 if not contraindicated, intraurethral or injection alprostadil, a vacuum device, a prosthesis - in a stepwise way. Price talk about one blister before that list is marketing, not a work-up.
Partners belong in the room when the man wants them there. A failure that only happens with one person and never on waking is information. A partner who has been blamed for 'not trying' is also information. The slip should hold both sentences before anyone quotes a milligram lock from this site.
Red flags that stop the folio
Stops that outrank any milligram lock
- Nitrate or popper still in use - no PDE5.
- Unstable or high-risk heart disease until a clinician clears sex.
- Erection lasting more than four hours - emergency care.
- Sudden vision or hearing loss - stop the drug, seek care.
- Young sudden loss, trauma, or a new painful bend - specialist, not a price.
- Morning T never drawn and desire is gone - draw before you crown a tablet.
Chest pain, syncope, or marked breathlessness with ordinary effort. A new neurologic deficit. An erection that will not die after four hours. Sudden vision or hearing loss after a tablet already taken. These are emergency or same-day files, not email questions.
A young man who lost rigidity overnight after a perineal injury, or who has a painful curve that is new, should not be priced a blister in a checkout line. Trauma and Peyronie's need hands-on exams.
Hidden nitrates include recreational nitrites. Ask in plain words. A man who says 'I only use a spray when I travel' still has a spray. The 10 mg versus strip folio and the QT slip cannot override that sentence.
Nerves and hormones that never fire
Pelvic surgery, radiation, spinal disease, multiple sclerosis, and diabetic neuropathy can interrupt the signal that tells cavernosal muscle to relax. A PDE5 needs that signal. After a nerve-sparing prostatectomy some men still get a partial response. After a non-sparing cut, expecting a first-line tablet to restore a baseline erection is often the wrong first card - injections, devices, or a surgical talk may belong earlier.
Morning total testosterone is an AUA moderate recommendation in men with ED. The usual threshold discussed with symptoms is under 300 ng/dL, drawn in the morning. Low desire, fatigue, and weak morning erections traveling together make that draw less optional. Testosterone is not an ED drug in a man whose level is already normal.
Thyroid disease and high prolactin are less common and still worth a thought when the story is odd - headaches, galactorrhea, visual-field complaints, or a failure that never looked vascular. Do not order a Christmas tree of hormones on every first visit. Do not skip the morning T because a tablet is cheaper to talk about.
Bind the work-up, then the molecule
Draw the story into vascular, nerve, hormone, and psych lanes - knowing they overlap. Note the morning testosterone and the heart-risk band. Shelf-check nitrates, antiarrhythmics, and the medicines that already blunt desire. Bind tests before anyone quotes a pill price.
A PDE5 is a reasonable first therapy for many men once those marks are clean. It is the wrong first card when the hold is dirty, the nerve is cut, the hormone is the main actor, or the couple has a problem a tablet cannot hear.
If the work-up says a tablet is fair, then - and only then - use this site's locks on the Copenhagen shelf. This folio will not sell you a favourite.

Reader questions on this review
Answered by Dr. Ingrid Halvorsen, MD · Internal medicine & clinical pharmacology
These readers wanted a price before a name for the failure. I send them back to tests, red flags, and the moments a PDE5 is the wrong first card. Teaching, not a chart for the person who wrote in.
Because the AUA says to measure morning serum total testosterone in men with ED, and because a low reading with symptoms changes the first card. Desire that has collapsed, weak mornings, and fatigue traveling together make the draw less optional. If T is already normal, testosterone will not treat the erection and we stop talking about gels. If T is low, a PDE5 may still be used - sometimes it works better once deficiency is treated - but pricing a blister while skipping the lab is how men stay hypogonadal and angry at 'weak pills.' Draw in the morning. Repeat if the first value is borderline and the story is loud.
He is rigid on waking and fails with me. Is a pill still first?
That pattern often means the plumbing and the nerves can still fill, and the failure is situational - anxiety, a couple who have started watching, a mismatch in timing. A PDE5 is sometimes used as a bridge to a first reliable success. It is not a substitute for saying the fear out loud, and it is a poor first card if he drinks heavily before every attempt. I would still want the medicine list and a morning T, because mixed pictures are common. I would not open at a 20 mg ceiling to 'overpower nerves.' If a tablet is used at all, it is a small, clean trial plus a plan for the loop, not a price hunt.
After prostate surgery, is a PDE5 even the first card?
It depends on what was spared. After a nerve-sparing operation, rehabilitation protocols often include a PDE5 as one tool. After a non-sparing resection, expecting an oral tablet to recreate a baseline erection is frequently the wrong first hope - injection, a vacuum device, or a prosthesis talk may belong earlier. Either way, the failure has a name: surgical disruption, not a missing brand. Do not shop milligram locks on this site as if they replace the operative note. Bring the operative note to a urologist who does this work.
Chest pain on ordinary stairs - do we price a tablet this week?
No. Sex is cardiovascular work. Pain on ordinary stairs is a heart file, not a Cialis file. High-risk or unstable disease needs evaluation and, often, stabilization before anyone discusses a PDE5. If a nitrate is already in the pocket, the tablet is contraindicated anyway. I would rather you spend the week on a cardiology appointment than on comparing 10 mg, 25 mg, and 2.5-or-20. The match file can wait. The stairs cannot.
Sudden complete loss overnight in a man of 34 - work-up or pharmacy?
Work-up. Overnight global loss in a young man is not a 'try the cheap diamond' story. Think trauma, a neurologic event, a new medicine, a psychogenic crash, or a vascular oddity that deserves hands. Morning erections, a medicine list, and a physical exam come before a price. If there was perineal injury, skip the internet and go to a specialist. A PDE5 can still appear later. It is the wrong first card on the night the rigidity vanished.
Low desire plus soft erections - hormone file or PDE5 file?
Start with the hormone file and the mood file, not with a ceiling dose. Collapsed desire is a testosterone and depression question as much as an endothelial one. Draw the morning T. Ask about sleep, prolactin-type clues, and the antidepressant already on the list. A PDE5 needs arousal to work. If there is no desire, you are asking a vascular drug to fix a different lane. Mixed pictures get both: treat deficiency if it is real, treat mood if it is real, then consider a tablet if rigidity is still the complaint.
Diabetes and cold feet - do we treat this as vascular first?
Yes, as a working hypothesis. Long-standing diabetes hits endothelium and nerves together. Cold feet, numb soles, and rising A1c are not decorations on an ED visit. Get the A1c, the blood pressure, and the lipids on the slip. A PDE5 may still help if some residual signal and some residual vessel remain. It will disappoint if you treat it as a candy on top of ignored glucose. Vascular first means name and treat the disease. Then, if the hold is clean, a tablet can be a later card - not the only card.
He is on an SSRI. Which test still happens before a blister?
The same core set: story, medicine list (the SSRI stays on it), morning testosterone, glucose, heart-risk look. The SSRI may be the main actor for delayed orgasm or flattened desire. That does not skip the T draw, because mixed pictures are common, and it does not license a parking-lot stop of a depression medicine. A psychiatrist and the prescriber share that change. A PDE5 is sometimes added when rigidity is the leftover complaint and the hold is clean. It is the wrong first card if the only problem is anorgasmia from the SSRI.
When is a PDE5 the wrong first card, in one sentence?
When the hold is dirty, the heart cannot take the work of sex, the failure is a cut nerve or an untreated hormone problem, or the couple's problem is not a cGMP problem. That sentence is why this folio exists. The three cards on this shelf - 10 mg, 25 mg, 2.5 or 20 - assume a PDE5-shaped remainder. If you cannot name the failure, do not price a remainder.
His partner says it is just stress. What still stays on the slip?
The partner may be partly right and still incomplete. Stress and a watching loop are real. So are diabetes, a new beta-blocker, a low morning T, and a nitrate nobody mentioned. What stays on the slip is the story, the full medicine list, morning testosterone, a glucose mark, and a heart-risk sentence. 'Just stress' is allowed as a hypothesis. It is not allowed as a reason to skip the work-up or to skip the holds. If the psych layer is truly the main actor, a therapist may be the first card. The tests still happen.
These replies are teaching, not a treatment plan for the person who asked. Take your own history, labs and medicine list to a prescriber who can see all three.
