If your father or brothers had premature ejaculation (PE), you may wonder whether it runs in the family. The honest answer is that genetics may play a part for some men, but the evidence is limited and no specific cause has been established. This article explains what we can and cannot say. It is general information and not a medical assessment.
What the family studies suggest
Some family and twin studies suggest that PE, especially the lifelong kind, tends to cluster in families more than chance would predict. The International Society for Sexual Medicine (ISSM) guideline describes genetic factors as a possible but minor contributor, and it treats most of the biological explanations as unconfirmed. We are not aware of research on South African families, and we do not quote figures.

Lifelong versus acquired
A possible genetic link is mostly discussed in connection with lifelong PE, which has been present since the first sexual experiences. Acquired PE, which develops later, is more often linked to other causes, such as medical conditions, erection problems or anxiety. See the types of PE and the overview of causes.
What this does not mean
- It does not mean that you will certainly pass PE on to a son, or that you are certain to have it because a relative did.
- It does not mean that nothing can be done. Many factors other than genes affect PE, including anxiety, habits, relationships and health.
- It does not mean that PE is your fault, or a sign of weakness.
- It is not a reason to avoid talking about it with your relatives or your doctor.
What helps regardless
Whatever the cause, the same practical steps apply: learning how PE works, reducing pressure and worry, talking to your partner and exploring options with a doctor or qualified practitioner. Outcomes vary and nobody can promise a result. See what can and cannot be promised and the overview of treatment options.
When to get assessed
If PE has been present for as long as you can remember, if it happens most of the time, or if it is upsetting you, it is worth being assessed. See a doctor if it began suddenly, or if you have pain or erection problems. Our page on when to see a doctor explains what to expect, and you can also try the private self-check.
