IVF treatment involves a lot of waiting!. Waiting to start, for results, for early pregnancy scans, and for the start of obstetric care. If you have just had an unsuccessful IVF cycle, the wait to try again can feel harder than the treatment itself. Many people in this position want a clear answer, quickly, so they may plan the months ahead with some certainty.
So, how many times can you do IVF in a year? In Australia, there is no legal or medical limit on the number of IVF cycles you can have. In practice, most people complete up to three or four stimulated cycles in a year.
Generally, fertility teams recommend waiting about one full menstrual cycle between Ovarian stimulation (or “Stim”) treatments. Frozen embryo transfers usually can go ahead sooner, with no adverse impact on the likelihood of getting pregnant.
At Surfcoast Fertility, we help patients across regional Victoria plan treatment timing that suits their body, their results and their wellbeing. Here is what shapes that timing.

How Many Times can I do IVF in a Year?
There is no set limit on how many In Vitro Fertilisation (IVF) treatments you can do in a year in Australia. The realistic number is shaped by your recovery between cycles, and for most people that means around three to four stimulated cycles within twelve months.
A single stimulated IVF cycle usually runs for about four weeks, from the start of ovarian stimulation through to egg collection, embryo transfer and the pregnancy test. Add the recommended recovery window between cycles, and the calendar fills quickly.
Recommended Time Between IVF Treatments
The general recommendation is to wait about one full menstrual cycle, roughly four weeks, after a negative pregnancy test before starting another stimulated IVF cycle.
This break gives your ovaries time to settle after stimulation and allows your hormone levels to return to baseline. Frozen embryo transfers (FETs) are different.
Because ovarian stimulation in a FET cycle is much more gentle, and sometimes is not needed at all, a FET may often proceed in your next cycle. Research has found no clinical benefit in delaying a frozen embryo transfer beyond the earlier 25- to 35-day window after a stimulation cycle
| Treatment Type | Typical gap Before Starting | Why the gap Matters |
|---|---|---|
| Stimulated (fresh) IVF cycle | About one full menstrual cycle (four to six weeks) | Allows ovaries and hormones to recover after stimulation |
| Frozen embryo transfer (FET) | Often the next cycle | No stimulation required, so less physical recovery needed |
| Cycle after OHSS or complications | Several weeks to two months, as advised | Your body needs to fully recover before further stimulation |
| Back-to-back stimulation (e.g. DuoStim) | Within the same cycle, in selected cases | Two egg collections in one cycle, only where clinically appropriate |
These are general guides, not rules. Your fertility team may recommend a longer or shorter interval based on your scan results, hormone levels and how you are feeling.
Factors That May Affect How Many IVF Cycles You Have in a Year
How many IVF treatments you can do in a year depends on more than the calendar. Physical recovery, emotional readiness, your age, whether you have frozen embryos, and practical factors like finances all play a part.
Key considerations include:
- Physical Recovery
Conditions such as ovarian hyperstimulation syndrome (OHSS) need to fully resolve before another stimulated cycle. - Emotional Wellbeing
Coping with IVF may affect emotional and mental health and may increase rates of depression, anxiety and stress. A planned pause between cycles may support your wellbeing. - Your age and Test Results
For some patients, particularly those in their late 30s or 40s, moving to the next cycle sooner rather than later. - Frozen Embryos
Having embryos in storage may shorten the gap between attempts, as a FET involves less physical load than a fresh cycle. - Cost and Logistics
Medicare rebates, private cover and time away from work all influence realistic pacing. Ballarat IVF Fertility group, and Surfcoast Fertility will review treatment costs for patients planning a Stimulation treatment cycle in the current calendar year
‘The number of cycles you fit into a year matters far less than what we learn from each one. Every cycle tells us something, and taking the time to listen to that, and to how you are feeling, is what may give the next attempt its best chance.’
– Dr Russell Dalton, Medical Director
Planning Your IVF Timeline With Surfcoast Fertility
Surfcoast Fertility plans treatment timing around each patient, not a set schedule. Your team reviews every cycle, what worked and what could be adjusted, before recommending when to begin again.
We virtually never use the Pill, or provera.
For selected patients, options such as DuoStim, which involves two ovarian stimulations within a single cycle, may be discussed as part of our IVF and women’s health treatments.
Counselling and planning support are also available through our support services, because the space between cycles matters as much as the cycles themselves.
In Vitro Fertilisation FAQs
Is IVF more likely to work second time?
It may be. Your team reviews everything learned from your first cycle, including how your ovaries responded and the quality of your embryos, and may adjust your treatment plan accordingly. Small changes in the treatment regimen can make a difference, but we often repeat the same treatment plan, especially if key information, such as hormone levels, and endometrial thickness were perfect. The biggest change for subsequent cycles is using a different embryo.
Many patients see outcomes improve across subsequent cycles, though results vary with individual factors like age and diagnosis.
How long should you wait between IVF attempts?
Most health professionals recommend waiting one full menstrual cycle after a negative pregnancy test, which is typically four to five weeks. Some patients may benefit from a slightly longer break of up to eight weeks; this is often to allow for personal time and stress management with the support of one of our counsellors.
How many IVF attempts on average?
There is no single average that applies to everyone, but many patients undertake two to three cycles before achieving a pregnancy, and some need more.
At what age is IVF most successful?
IVF outcomes are generally strongest for women under 35, as egg quality and quantity naturally decline with age. That said, many patients in their late 30s and beyond achieve pregnancies through IVF.
What is the success rate of IVF in Australia?
Success rates vary with age and individual circumstances, so no single figure applies to everyone. According to the 2023 ANZARD report from UNSW, in the most recent year with complete data, the live birth rate per initiated cycle was 23.8%, and about one in 16 babies born in Australia was conceived through IVF.

Wondering When Your Next Cycle Could Start?
There is no rule that caps how many times you can try IVF in a year. What matters is giving your body time to recover between stimulation cycles, protecting your emotional well-being, and allowing each treatment to be reviewed before the next begins.
Surfcoast Fertility in Geelong has been supporting families across regional Victoria since 2010, with a doctor-owned team that reviews every cycle personally, plus counselling and telemedicine support between treatments.
