Understanding Timelines

IVF and OI Timeline

IVF and OI: first steps

In assisted reproductive technology, timing is everything and that’s why it’s important to understand the timelines. Your medical treatment will typically begin based on your natural cycle and the timeframe for each step may vary depending on your individual response.

In IVF and OI, you may begin with oral contraceptives for 3-4 weeks (or longer in some cases), followed by about 2 weeks of hormones to prevent ovulation and encourage follicle growth—typically a GnRH analogue, another hormonal drug called follicle-stimulating hormone (FSH), and, if appropriate, human menopausal gonadotropin (HMG). Your progress during this treatment will be closely monitored to keep track of egg development and properly time next steps.

Based on these tests, your team will determine when you are ready for the hCG trigger—another single hormonal injection that helps in the eggs final development. Following this, you will be ready for egg retrieval. If you are retrieving eggs for cryopreservation (freezing), this is typically when your treatment process will end.

Embryo Transfer

Once your eggs have been retrieved and fertilized and one or more healthy embryos have been selected, you will undergo embryo transfer—this typically 2, 3, or 5 days after egg retrieval depending on the number and quality of embryos. Your first pregnancy test will typically take place 2 weeks following transfer.

Luteal support

If you are undergoing IVF with embryo transfer, you will likely begin treatment with progesterone following egg retrieval. This is called luteal support, and is intended to help prime the womb for the best chance of implantation and pregnancy. There are several different progesterone options available but most will be taken for about 10 days.

Additional cycles or transfers

For many patients, one cycle doesn’t result in a pregnancy. If you’ve frozen embryos for transfer or are starting a new cycle, you may wish to try again as soon as possible. You and your care team can work together to determine a healthy schedule that is most likely to succeed!
