Natalist’s Guide to IVF is an easy-to-understand, comprehensive explanation of IVF intended to demystify the process and empower you to take charge of your IVF journey. Chapter six of the book is titled Step by step: How IVF works. Today we’ll be giving you a sneak peek of the sixth out of seven steps Halle outlines in the book.
Embryo Transfer
Ah, transfer day! This is one of the most exciting, and sometimes nerve-wracking, moments during IVF! You will get to see your embryo and watch on the screen as the doctor transfers it from the lab to your uterus.
If you’re doing a frozen embryo transfer, you’ll spend about three weeks preparing for the transfer day. Depending on your specific clinic and diagnosis, you can do a natural cycle transfer or a medicated transfer. In a natural cycle transfer, the embryo is transferred after your natural ovulation. In a medicated transfer, you take about 2 weeks of estrogen to thicken your uterine lining. Once the lining reaches an optimal thickness (typically > 7mm) your doctor will prescribe progesterone to prepare for your embryo transfer. [1-2] Progesterone is often given in an intramuscular (IM) injection. The IM injection can be uncomfortable so be sure to ask your clinic for tips to make it more tolerable. [1-2]
The embryo transfer is a simple procedure that takes only a few minutes. But before it begins, you will be asked to have a full bladder [1-2]. It can take a while to get a full bladder, especially if you can’t hold it long enough and need to start over!
Before the procedure begins, some doctors may give you a mild sedative to help you relax [1-2]. You will then lie on the exam table with your feet in stirrups. The embryo, which has been previously selected based on its quality and viability, is placed in a thin, flexible tube called a catheter. The catheter is then passed into your uterus. The embryo is then gently pushed out of the catheter and into the uterus to hopefully snuggle in and implant. [3-4]
Preparing for the transfer
There are several steps that you can take to prepare for the embryo transfer:
- Review your treatment plan
- Take your medications as prescribed
- Follow a healthy lifestyle
- Follow your clinic’s instructions
