Catching a cough or cold during IVF or fertility treatment can feel stressful — after all, you’ve planned every step carefully and want your body in peak condition. The good news is that a mild viral infection is very common and rarely harmful to your fertility or treatment outcome.

Most colds and coughs are caused by everyday viruses. They don’t affect egg quality, implantation, or embryo development. What matters most is how you care for yourself while your immune system does its job.

Practical advice if you get sick during treatment

  • Rest and stay hydrated. Fatigue is your body’s way of asking for recovery time. Sleep, fluids, and gentle nutrition will help you bounce back faster.
  • Be cautious with medications. Not all over-the-counter cold remedies are suitable during stimulation or early pregnancy. Always check with your fertility clinic before taking anything new.
  • Monitor your temperature. A mild fever is usually harmless, but a persistent or high fever should be discussed with your team — especially close to egg collection or embryo transfer.
  • Keep your clinic informed. Even minor illnesses are worth mentioning. Occasionally, procedures can be safely postponed by a few days if needed to protect your wellbeing.

At REN Fertility, we remind our patients that a cold doesn’t mean your cycle is lost. With rest, care, and good communication, treatment can usually continue without disruption.

In short: if you’re coughing or sniffling during IVF, don’t panic. Most coughs and colds are self-limiting, and your fertility team is here to support you every step of the way.
