People living with HIV can conceive, have a healthy pregnancy, and give birth to HIV-negative babies. With modern treatment, the risk of passing HIV to a baby is less than 1% when the mother is on effective treatment with an undetectable viral load.
If you’re thinking about having a baby, talk to your HIV team early. Preconception planning makes everything smoother and gives you and your baby the best possible start.

Can I Have a Baby with HIV?
Yes. In the UK, the vast majority of babies born to HIV-positive mothers are HIV-negative. The key is being on effective ART with an undetectable viral load throughout pregnancy and delivery.
Planning Ahead
Ideally, start the conversation with your HIV team several months before you want to conceive. They will:
- Check your viral load is undetectable
- Review your ART to make sure it’s safe in pregnancy
- Check immunity to infections like rubella and chickenpox
- Offer vaccinations if needed
- Discuss your partner’s HIV status and testing
Conception Options by Situation
| Situation | Approach |
|---|---|
| Woman HIV+, partner HIV-, woman on effective ART (U=U) | Condomless sex during fertile window is safe. No risk of transmission. |
| Man HIV+, partner HIV-, man on effective ART (U=U) | Condomless sex is safe. Partner may take PrEP for extra reassurance. |
| Both HIV+ | Condomless sex is fine |
| Either partner with detectable viral load | Delay until undetectable, or consider assisted conception |
During Pregnancy
Most pregnancies proceed as normal. You’ll have your usual antenatal care plus regular HIV clinic appointments. Viral load is checked more often, especially near delivery. The aim is to have an undetectable viral load by 36 weeks.
Delivery
If your viral load is undetectable (below 50 copies/ml) at 36 weeks, vaginal delivery is usually safe and is often recommended over caesarean. If the viral load is higher, a planned caesarean is offered to reduce transmission risk.
After the Baby Is Born
- Babies are given antiretroviral medication for 2-4 weeks after birth as a precaution
- They are tested for HIV at several points during the first 6 months
- In the UK, the NHS advises formula feeding rather than breastfeeding, although breastfeeding with undetectable viral load is increasingly supported as an option with careful monitoring
If You’re Trying and Not Getting Pregnant
HIV itself does not usually reduce fertility, but some conditions linked to HIV can. If you’ve been trying for more than a year (or six months if you’re over 35), ask your GP or HIV team about fertility assessment.

Frequently Asked Questions
Can I pass HIV to my baby during pregnancy?
The risk is less than 1% when you’re on effective treatment with an undetectable viral load throughout pregnancy and delivery.
Will my HIV medication harm the baby?
Most modern HIV medicines are considered safe in pregnancy. Your HIV specialist will review your regimen to make sure it’s the best option.
Can I breastfeed with HIV?
In the UK, formula feeding is still the recommended default. Some clinics now support breastfeeding with undetectable viral load and close monitoring, but this should only be done with the full support of your HIV team.
