Red flags

  • PDE5 inhibitor use with concurrent nitrates (or riociguat) — absolute contraindication; severe hypotension/collapse risk
  • Priapism after erectile pharmacotherapy — urological emergency
  • ED as a cardiovascular risk marker — do not treat with sildenafil alone while ignoring diabetes, lipids, and angina
  • Active suicidal ideation after sexual failure, relationship collapse, or fertility despair — same-day risk assessment
  • New ED with neurological red flags (saddle anaesthesia, progressive weakness) — urgent medical/neurology pathway
  • Severe antipsychotic hyperprolactinaemia with hypogonadism driving ED — revise regimen when psychosis control allows

The one-line answer

Erectile disorder and ejaculatory disorders (premature or early, and delayed) are phase-specific sexual dysfunctions requiring distress, careful organic-versus-psychogenic discrimination, and stepped care — lifestyle and psychosexual therapy as first principles, PDE5 inhibitors for suitable ED (with the absolute nitrate contraindication), and behavioural plus SSRI or dapoxetine strategies for PE — while never missing ED as a cardiovascular risk marker or iatrogenic SSRI or antipsychotic causation.[5][6][7][10]

Meet the patient

A 54-year-old man, eight weeks after a myocardial infarction, is referred by his GP for "anxiety about sex". He has not been able to get an erection since the MI, avoids the topic with his wife, and has started sleeping in the spare room. He is convinced the exertion will kill him. His HbA1c, never checked before the stent, comes back elevated.[2][6]

This is leaf examiner uses to test three things at once: phase mapping (is this erection or ejaculation?), safety (the nitrate question is never far away), and the cardiovascular hidden curriculum — because ED is often the first presentation of endothelial disease, and sildenafil without checking the sugars and lipids is a missed diagnosis.[3][6]
