IVF treatment involves a period of several weeks where certain activities are restricted — but travel is not automatically one of them. Many patients worry unnecessarily about flying or going away during treatment, while others don't realise there are specific points in the cycle where travel genuinely requires care.
This guide addresses the most common travel questions patients have during each phase of an IVF cycle.
Before Stimulation Starts
Can you travel freely before starting a cycle?
Yes. Before stimulation begins, no restrictions apply. If you are taking down-regulation medication (in a long protocol), these injections can generally be continued while travelling — they require refrigeration, so plan accordingly, and carry them in hand luggage.
During Stimulation (Injections Phase)
Can you travel during stimulation?
Short trips are generally possible, but stimulation requires monitoring scans (typically 2–3 ultrasounds) during the 10–14 day injection phase. You need to be within reach of a clinic that can do monitoring scans, either at your treating clinic or at a local fertility unit that offers monitoring services.
Many UK fertility clinics and private scanning services offer standalone monitoring for patients travelling or being treated at a clinic in another city or country.
What about flying during stimulation?
Flying during stimulation is not medically prohibited, but practical considerations apply:
- Medication storage: FSH injections must be kept refrigerated until use. Airlines allow fertility medication in hand luggage with a doctor's letter, but cold chain management during travel requires planning (cool bags, ice packs permitted through security).
- Access to scanning: You need monitoring scans at specific points during stimulation. If flying to a destination, ensure a monitoring clinic is arranged in advance.
- Rapid escalation: If your stimulation response is unexpectedly high (OHSS risk), you need to be able to reach your clinic for assessment. Long-haul travel during stimulation is therefore higher risk than domestic or short-haul trips.
Can you go abroad during stimulation?
Some patients manage entire stimulation cycles while based abroad, with monitoring at a local clinic and all results shared with the treating clinic. This requires advance planning and a reliable communication pathway with your clinic. For short trips (2–3 days) where monitoring scan timing is not critical, international travel during stimulation is manageable. For longer absences, discuss with your clinic first.
Around Egg Collection
Can you fly to the egg collection destination?
Yes — this is the standard for patients having IVF abroad. Travel on the day before egg collection is normal practice.
Can you fly immediately after egg collection?
Most clinics advise against flying on the day of egg collection itself (you are recovering from sedation and should not drive or operate machinery). Flying the following day is generally acceptable if you feel well. Comfort-wise, the abdominal bloating common after egg collection may make a long flight uncomfortable.
What about OHSS risk?
If you are at risk of ovarian hyperstimulation syndrome (OHSS), flying creates specific risks: dehydration at altitude can worsen OHSS, and the DVT risk from long flights is elevated in patients with significant OHSS (which creates a prothrombotic state). If OHSS develops after egg collection, flying should wait until your clinic confirms it is safe.
For patients whose cycle is managed with a freeze-all approach (embryos frozen, no fresh transfer), leaving the country after egg collection — once you have recovered and OHSS is not developing — is generally fine. You return for the FET at a later date.
Around Embryo Transfer
Can you travel to the clinic for transfer?
Yes. International travel for embryo transfer is the normal model for patients having IVF abroad. A transfer trip typically involves arriving 1–2 days before transfer (for a pre-transfer scan and lining check) and returning home 1–2 days after.
Should you rest after embryo transfer?
Evidence does not support bed rest after embryo transfer. Studies consistently show no difference in implantation rates between patients who rest and those who resume normal activities. Travelling home — including flying — after embryo transfer is not contraindicated.
Short-haul flights (under 4 hours) on the day of or day after transfer are widely practised by patients having IVF abroad without evidence of harm. Long-haul flights are similarly considered safe, though comfort during abdominal bloating may be an issue.
During the Two-Week Wait
Can you go on holiday during the two-week wait?
Yes. There are no medical restrictions on travel during the two-week wait. Many patients find a holiday or break during this period helpful for managing the anxiety of waiting. There is no evidence that travel, flying, swimming, or other holiday activities affect implantation.
Practical considerations for the 2WW:
- Continue progesterone pessaries or injections as prescribed — these must be kept available (and refrigerated if injectable)
- Ensure you know what to do if bleeding or unusual symptoms occur while away
- Confirm whether the clinic wants a blood test or urine test at day 14 — a blood test requires a clinic or lab
What if the test is positive while you're abroad?
A positive pregnancy test while overseas does not require emergency action. Follow up with your clinic by phone or email, continue progesterone as prescribed, and arrange a scan when you return. Routine early pregnancy monitoring does not need to happen the same day as the positive test.
Medication and Travel
Taking IVF medication through airport security:
- Carry all medication in hand luggage — never in checked bags (temperature variation and risk of loss)
- Carry a letter from your clinic or prescribing doctor explaining the medication
- Syringes and needles are permitted through UK security with a medical letter; most other countries also permit this with documentation
- Refrigerated medication: cool bags and ice packs are permitted through security. Pre-cooling the bag before packing is more important than the ice pack itself for short journeys
Frequently Asked Questions
Q: I have a work trip that requires flying during stimulation. Is this a problem?
A: It depends on the length of the trip and whether monitoring can be arranged at your destination. A 2-day domestic or short-haul business trip during stimulation is manageable with advance planning. A week-long overseas trip may be more difficult to fit around monitoring requirements. Discuss with your clinic — they may be able to adjust the monitoring schedule or advise on remote monitoring options.
Q: Can I go to a hot country during the two-week wait?
A: Yes, with sensible precautions. There is no evidence that heat affects implantation. Avoid hot tubs and saunas (associated with raised core body temperature, which is generally advised against in early pregnancy), but sunbathing, swimming, and normal holiday activities are fine.
Q: I have progesterone pessaries — how do I travel with them?
A: Progesterone pessaries do not typically require refrigeration (check the specific product's storage requirements). They can be carried in hand luggage with the prescription paperwork. They can be warm, but avoid storing at very high temperatures for extended periods.
Q: Is there any risk from going through airport body scanners during IVF?
A: Airport security scanners (millimetre wave or X-ray body scanners) use very low-level radiation and have not been shown to have any effect on fertility, embryos, or early pregnancy. There is no medical basis for requesting manual search rather than scanner to avoid supposed risk during IVF.
Q: We planned a holiday during what will be my stimulation phase. Should we cancel?
A: Not necessarily. Whether to proceed with the holiday depends on how far abroad you're going, whether monitoring can be arranged, and how important the timing of the cycle is to you. For a short European trip, it may be entirely manageable. For a long-haul destination where monitoring arrangements would be very difficult, delaying the cycle by one month to avoid the conflict is often the simpler choice.
