Can RA, PsA or JIA affect pregnancy or fertility? 

For many people living with inflammatory arthritis—whether it is Rheumatoid Arthritis (RA), Psoriatic Arthritis (PsA), or Juvenile Idiopathic Arthritis (JIA)—planning a family comes with unique questions. The good news is that these conditions do not typically prevent a person from having a healthy pregnancy or a healthy baby. However, because inflammatory arthritis is a systemic condition that often requires long-term medication, careful planning and coordination with your rheumatology team are essential. In the UK, specialists aim to help patients achieve stable disease activity before conception to ensure the best possible outcomes for both parent and child.

Inflammatory arthritis does not directly cause infertility, but active inflammation and certain medications can make it more difficult to conceive. Most people with RA, PsA, or JIA can have successful pregnancies, provided their disease is well-controlled. The NHS notes that most women with rheumatoid arthritis find their symptoms improve during pregnancy, though they may experience a flare-up after the baby is born. 

Fertility and Conception 

While the conditions themselves do not usually stop you from getting pregnant, active inflammation can affect the body’s reproductive environment. In women, high levels of systemic inflammation can sometimes lead to longer times to conception. In men, certain medications and active disease can occasionally affect sperm quality. 

The most significant factor regarding fertility is medication. Some drugs used to treat arthritis are not compatible with trying to conceive. 

Methotrexate: 

This is a major concern for both men and women. It must be stopped several months before attempting to conceive because it can interfere with the development of the baby. 

NSAIDS: 

Long-term use of anti-inflammatories can sometimes interfere with ovulation. 

Biologics: 

Many modern biologics are now considered safe to continue up until a certain point in pregnancy, but this must be discussed with a consultant. 

The “Pregnancy Glow” and Arthritis 

A fascinating aspect of inflammatory arthritis is that many women experience a significant reduction in joint pain and swelling during pregnancy. This is often attributed to natural changes in the immune system designed to protect the developing baby. 

However, this remission is not guaranteed for everyone, and it is particularly less common in Psoriatic Arthritis compared to Rheumatoid Arthritis. It is also important to prepare for the postpartum flare. Within the first few months after giving birth, as hormones and the immune system return to their baseline, many people experience a return or worsening of their arthritis symptoms. 

Medication Safety and Pregnancy 

The most important step for any person with arthritis planning a pregnancy is a pre-conception review. In the UK, your rheumatologist will work with you to create a pregnancy-compatible treatment plan. 

Medication Category	Common Examples	Pregnancy Guidance
Non-Compatible	Methotrexate, Leflunomide	Must be stopped (typically 3-6 months prior)
Usually Compatible	Sulfasalazine, Hydroxychloroquine	Often continued to maintain stability
Biologics	Adalimumab, Certolizumab	Often safe; some stopped in the third trimester
Corticosteroids	Prednisolone	Generally safe at low doses if needed for flares

The British Society for Rheumatology provides detailed evidence-based guidelines on which medications can be safely used during pregnancy and breastfeeding, ensuring that parents can keep their inflammation under control without harming the baby. 

Managing Your Care in the UK 

If you have JIA, RA, or PsA and are pregnant or planning to be, your care will likely be shared between your GP, your midwife, and your rheumatology team. You may be referred to an obstetrician who specialises in high-risk pregnancies, not because your baby is in danger, but to ensure your medication and joint health are monitored closely. 

Specialists recommend aiming for at least 3 to 6 months of stable, low disease activity before trying to conceive. This reduces the risk of flares during pregnancy and helps ensure you have the physical strength and mobility needed for late pregnancy and early parenthood. 

Conclusion 

Inflammatory arthritis presents extra hurdles for family planning, but it does not mean parenthood is out of reach. With early planning, medication adjustments, and close monitoring, the vast majority of people with RA, PsA, or JIA have healthy, successful pregnancies. The key is to have open conversations with your medical team well before you stop your contraception. If you experience severe abdominal pain, heavy bleeding during pregnancy, or a sudden flare that prevents you from moving safely, call 999 or contact your maternity unit immediately.
