Lower sex drive or erection changes: where to start
A broader starting point for changes in desire or erections, including what to tell a GP and why a hormone test is only one possibility.

The short answer
Changes in desire and difficulty getting or keeping an erection are different concerns, and both can have several causes. They do not automatically mean low testosterone. Speak to a GP or sexual health service if erection problems keep happening, or to a GP if low desire worries you.
Describe the change in your own words
It may be less interest in sex, an erection that does not last, or both. Say when it began, whether it is occasional or persistent and what is bothering you most. You do not need a medical label before asking for help. A clinician can ask the further questions needed to understand the pattern.
Keep more than hormones in view
The NHS describes several possible contributors, including stress, relationship difficulties, medicines, alcohol and physical health conditions. Recurrent erection problems can warrant a wider health assessment. Testing testosterone may be appropriate in some circumstances, but choosing it first from a shopping page can leave the original concern insufficiently explored.
Prepare for the conversation
Bring an accurate list of prescribed medicines, non-prescription treatments, supplements and any hormones used. Note changes in sleep, mood or health and whether future children matter to you. You can ask for a private conversation, explain that a topic feels awkward, or bring notes so you do not have to remember everything under pressure.
Agree a route that fits the cause
Help may involve looking at a condition, reviewing medicines or supporting emotional and relationship concerns. Treatment depends on the assessment. Do not stop a prescription because its leaflet mentions sexual side effects, or assume that an online hormone or erection product is suitable. Ask the prescriber or pharmacist about your particular medicines.
One useful next step
If the problem is recurring or worrying you, book an appropriate appointment and write one sentence about the main change you want help with. Ask what assessment is proposed, what it can establish and how follow-up works. Ask Timber can explain general terms and help organise questions; the individual assessment belongs with a healthcare professional.
