IVF Timeline: What Happens From Start To Finish?

The active IVF cycle typically takes four to six weeks from the treatment start date to a pregnancy test. If you factor in the first consultation, testing and treatment planning, an initial IVF cycle usually lasts six to eight weeks.

When talking about the IVF treatment timeline, it is helpful to split it into three distinct phases:

1. Clinic waiting time – the time it takes to get an appointment and have your initial consultation.
2. Pre-treatment preparation – the phase in which tests, investigations and treatment planning are completed.
3. The active IVF cycle – the treatment stage, beginning with the first medications and culminating in a pregnancy test.

All three stages impact the total time required to complete a cycle.

The IVF timeline can be extended by clinical scheduling, any tests required, donor selection and treatment specifics, such as stimulation protocols and the type of embryo used.

• Clinical scheduling – fertility clinics need to schedule tests, consultations and treatment, and availability can influence how long this takes.
• Testing – additional testing may be required in some cases.
• Choosing a donor – the process of choosing a donor, ensuring availability and transporting donor sperm or eggs may impact the timeline.
• Treatment protocols – some IVF protocols involve the suppression of normal hormonal activity before ovarian stimulation begins, adding time to the total.
• Type of embryo – a fresh embryo transfer typically takes place sooner in the cycle than a frozen embryo, while PGT (preimplantation genetic testing) embryos extend the cycle further. 
• Individual response – an individual’s response to ovarian stimulation may delay embryo transfer.
• Additional cycles – if the first cycle is unsuccessful and further cycles are required, the overall treatment timeline can be considerably longer.

The IVF timeline for a single cycle runs for six to eight weeks and features nine main steps. However, these nine steps are not evenly distributed across the timeline. While the start and end of the six- to eight-week period involve more waiting, the third and fourth weeks are busier, with several steps condensed into a short time.

Using donor sperm for IVF treatment is very common and will not add much time to the process. The only additional step is finding the right sperm donor for your family. At European Sperm Bank, we simplify this with detailed donor profiles and with the help of our tools Personality Explorer and Photo Match. Once you have found your sperm donor, you can order the required donor straws, and we liaise with your fertility clinic to arrange delivery and ensure your straws are ready for the start of your treatment.

IVF often involves several appointments and visits to your fertility clinic. However, they tend to be concentrated around the ovarian stimulation stage, as regular monitoring is necessary. This means it is possible to arrange IVF appointments around work, daily life and other commitments. Many people continue to work throughout the treatment cycle, but flexibility is important.

Understanding when appointments are likely to occur and how frequently can help you plan ahead. 

• Ovarian stimulation – monitoring appointments typically take place every few days early in stimulation but become more frequent as follicles develop. Eventually, you may require daily appointments, but your clinic will advise on exact scheduling.
• Egg retrieval – retrieval is a quick procedure, but people react differently to it. Many people need the rest of the day off, as it can result in cramping, bloating and tiredness. If you are sedated during retrieval, someone may need to drive you home.
• Embryo transfer – though your fertility clinic will monitor embryo development closely, they can make short-notice decisions when it comes to embryo transfers. Be prepared to attend your transfer from the second or third development day onwards.
• Keep your diary free – while you can work around clinic appointments, the IVF timeline is unique to every individual and depends on monitoring results. Avoid making other commitments around key dates, in case the timeline changes.

How long does one IVF cycle take?

A single IVF cycle typically takes six to eight weeks, though it can vary depending on your treatment specifics. As you may require more than one IVF cycle to get pregnant, the overall treatment journey may be longer.

What day of your cycle do IVF injections start?

Many IVF protocols start ovarian stimulation injections around day 2 or 3 of your menstrual cycle.

However, there is no universal starting day. Some protocols involve medication before stimulation or use different approaches to control ovulation and coordinate the cycle. Your fertility clinic will tell you exactly when injections will start based on the protocol they have selected for you.

How many days are IVF injections?

Ovarian stimulation injections typically last for about 10–14 days. However, the exact number is determined through follicle monitoring and varies between individuals. When you are ready, you receive a trigger injection, and egg retrieval usually happens 36 hours later. 

How long after egg retrieval is embryo transfer?

Embryo transfer typically takes place between days three and six if you have a fresh embryo transfer. However, the timing depends on how long the embryos are cultured. With a Day 3 transfer, the embryo is at the multicellular stage. It is possible to successfully transfer an embryo at this stage, but most clinics prefer to wait until Day 5 or 6 when it reaches the blastocyst stage.

If embryos are frozen, the transfer does not happen during the same part of the cycle. The embryos are frozen and transferred during a later frozen embryo transfer (FET) cycle. The timing of that transfer depends on how your uterine lining is prepared and the protocol used by your clinic.

How long should you wait between IVF cycles?

There is no standard wait time between cycles, and the interval required depends on how you respond to and recover from the previous cycle, as well as your fertility specialist’s professional opinion. In some situations, another treatment cycle can start relatively soon after the previous one ends. In other cases, you may want to wait a while, or your clinic may recommend carrying out further investigations first.

Does PGT make the IVF timeline longer?

Yes, Preimplantation Genetic Testing (PGT) usually extends the IVF timeline because embryos are frozen after the biopsy takes place and testing is conducted. Results are not available immediately, so a fresh embryo transfer is not performed.

Once the PGT results are available, your clinic will identify suitable embryos and plan a frozen embryo transfer in a later cycle.
