Sexual Health & Fertility
Straight, evidence-based answers on erections and sex drive, with no shame and no sales pitch. Often an early signal of wider health worth acting on.
Erection problems and low desire are common, treatable, and among the least discussed symptoms in men's health. This hub treats them as medical questions rather than as personal failures.
One theme runs through it and it is the reason to read rather than wait. Persistent erectile dysfunction can be a cardiovascular risk marker, but it does not prove a vascular cause or heart disease. Because causes often overlap, assessment should cover cardiovascular risk, medicines, hormones, neurological contributors and psychological factors.

Low sex drive in men: the causes worth checking first
A practical guide to low libido in men: medication, mood, relationships, sleep, thyroid, prolactin, diabetes, testosterone and when to seek care.
Erectile dysfunction: causes, and when it is a warning about your heart
Why ED can be an early sign of a circulation problem, how physical and psychological causes overlap, what a doctor may check, and which treatments help.
Where to start
- Erectile dysfunction Causes, what your doctor should check, and why it matters for your heart.
- Signs of low testosterone Read this if desire has dropped alongside erections, because the two point in different directions.
- TRT: benefits and limits What treatment does and does not fix, including the sexual outcomes from the largest trial.
What this hub answers
- Is erectile dysfunction a heart warning?
- It can be a cardiovascular risk marker, but it does not prove heart disease or state an individual's absolute risk. A clinician can assess blood pressure, glucose, cholesterol, smoking, age and other factors; ED can precede cardiovascular symptoms in some men.
- Is low desire the same as erectile dysfunction?
- No. Desire and erectile rigidity are separate domains. Preserved interest does not identify the cause of ED: vascular, neurological, hormonal, medicine-related and psychological contributors can overlap. A clinician should assess the full pattern rather than infer blood flow from libido alone.
- Does low testosterone cause erection problems?
- It is rarely the only cause. A morning total-testosterone measurement belongs in the initial assessment of men with ED; low libido makes testosterone deficiency more plausible, but it is not a prerequisite for testing.
