When You are Ready

When You are Ready

When you are ready to get pregnant, your eggs will be fertilized and an embryo will be transferred into your uterus in a regular IVF procedure.




Your eggs can remain frozen indefinitely until you are ready to conceive. At that time, they will be thawed, fertilized, and hopefully developed to a 5-6 day old embryo, called a blastocyst.


Each egg will be directly injected with 1 sperm by a process called intracytoplasmic sperm injection (ICSI). Research has shown that ICSI is most successful method to fertilize thawed eggs.

Embryo culture

After the eggs are fertilized, they will be maintained in the laboratory incubators. Typically most eggs do not lead to healthy embryos, but most patients who freeze eggs before the age of 35 will have enough eggs to produce 2-4 healthy appearing embryos.


Embryo transfer is a simple procedure that does not require anesthesia. An embryo is loaded into a transfer catheter that passes through the vagina and cervix, into the uterus.  Your doctor may use an ultrasound as a guide to placing the embryo into the uterus. After the procedure, you are free to go home.

Embryo Transfer


Once the embryo is transferred, pregnancy occurs when the embryo imbeds itself into the wall of the uterus, where it begins to develop the placenta and fetus.


PGT-A (also called CCS) is a screening technique that is used with IVF. It involves carefully removing a few cells from the embryo and analysing whether it has the correct number of chromosomes. A healthy embryo should have 23 pairs of chromosomes.

What Are the Advantages of PGT-A?

Selecting embryos that have been identified as normal with PGT-A can:

  • Increase pregnancy rates to >75%
  • Reduce miscarriages rates 10%-12%
  • Minimize risks for chromosomal anomalies such as Down syndrome.
  • Allow chromosomally normal embryos to be frozen for future use.

After Your Transfer

You will have a pregnancy blood test about 15 – 18 days after your embryo transfer.

If positive, we will do 2 early ultrasound scans at 6 weeks and 8 weeks to determine if the pregnancy is progressing as expected.

Once you’ve had your 8 week scan, you “graduate” from Olive. We will refer you to the doctor or midwife and they will be following you through your pregnancy.
