Timeline

IVF Overview

This process takes place over a woman’s 4 week menstrual cycle and is part of a broader range of services in reproductive health and obstetrics and gynaecology.

Week 1–2: Controlled Ovarian Stimulation

IVF takes place over a woman’s 4 week menstrual cycle. Injections are taken taken for about 10-12 days to stimulate the ovaries to mature a group of follicles (containing the eggs). It seems overwhelming to give yourself injections but you will be shown how to do this in a detailed education session with one of our fertility nurses. And don’t be afraid to ask questions. No question is too big or too small. If you have problems, we are available 24 hours per day to answer your questions.

You will go to one of our early morning clinics a few times in the first two weeks. This is to check your ovaries (with a pelvic ultrasound) and to check your hormones (with a blood test). This is done by one of our fertility nurses. You will be called in the afternoon to let you know how you are progressing.

Generally after you have taken the injections for about 12 days, your ovaries are ready and we can prepare for the egg collection. You are given a trigger injection so that the eggs will go through the final maturation process.

End of Week 2: Egg Collection & Semen Collection

You will given a time for the egg collection. I will be there to see you before the egg collection. I will go through the process and answer any questions. The embryologist (scientist) will also see you and go through any final questions. The egg collection takes 5 minutes. There is an anaesthetist and you are asleep. I drain the fluid in the follicles in the ovaries. I collect the fluid and the embryologist looks under a microscope and separates the eggs. The eggs are then taken to the embryology lab where they are put together with the sperm. You will wake up and we will tell you how it went and how many eggs were collected. You can go home and rest for the remainder of the day. Many women will go back to work or their usual duties the next day. We will call you the next day to see how you are going. You will start the progesterone on the night after the egg collection.

Your male partner will be asked to provide a sperm sample at the embryology lab. This is on the day of egg collection. If you are using donor sperm, this is thawed on the day of the egg collection.

Week 2–3: Fertilisation & Embryo Growth

The eggs and the sperm are put together in a special dish. You will be called the following day by the embryologist to let you know how the fertilisation process went.

The progress of the embryos over the next 5 to 6 days is carefully recorded by an embryoscope. Photos are taken of the development of the embryos. This gives the embryologists the opportunity to select the best embryo to use later when you come back in for an embryo transfer. You will be contacted regularly to update you on the progress of your embryos.

Week 3: Embryo Transfer & Storage

After 5 days you will come in for an embryo transfer. This takes 5 minutes and is like a pap smear. You will need to have a slightly full bladder. You will be given a copy of the final picture of your embryo. I will be there again to place the best embryo inside your uterus. The position is checked by a pelvic ultrasound.

You will be contacted about the remaining embryos. These can be stored on day 5 or day 6 if they reach the benchmarks to result in a pregnancy.

Week 4: Pregnancy Test

There is then a 9 day wait before the pregnancy test. During this time do not do anything to overheat – such as a spa or sauna. We also recommend that you don’t do anything to force water up at high pressures – such as bungee jumping or waterskiing! I imagine that most women aren’t planning those activities in the days after an embryo transfer.

You will have a pregnancy test after 9 days. You can call us at anytime during this period if you need to. We are always around. We understand that this waiting time can be very stressful.

Finally, we always aim for a positive result. And this is wonderful if it happens the first time. But if it is not a positive result, I am there to talk you through the next steps and to encourage you to keep going. I am there to be supportive because I understand the emotional rollercoaster which can happen when you are going through fertility treatment. We will always look at different things which can be done to get you a positive result.

Genetic testing of embryos

Monash IVF has a state-of-the-art genetics lab and offers several genetic testing options and support with in-house counsellors. Genetic testing is not required for everyone. I can talk to you about whether it is right for you.

To perform genetic testing on an embryo, the embryologist will remove (biopsy) a small number of cells (~ 5-7 cells) from the embryo once it reaches the blastocyst stage (about Day 5 of development). The cells which are biopsied are those that would contribute to the placenta. The embryos are then cryopreserved while the biopsied cells are sent for genetic testing.

There are different genetic tests which are available. PGT-A (Pre-implantation Genetic Testing – Aneuploidy) refers to the most common test which looks to see that the embryo has the correct number of chromosomes. PGT-M (Monogene) is testing for a specific gene mutation such as cystic fibrosis. PGT-SR (Structural Rearrangement) is a test looking for a structural rearrangement of a chromosome.

PIEZO-ICSI

This is a modified version of ICSI which is currently only offered in Australia by Monash IVF but is used extensively elsewhere around the world. Unlike traditional ICSI, which uses a sharp needle to inject sperm into the egg, PIEZO-ICSI employs a blunt needle combined with micro-vibrating motions to inject the sperm. This gentler approach reduces the risk of damaging the egg’s delicate outer membrane. In select patient groups we have found that PIEZO-ICSI shows improved outcomes compared to traditional ICSI.

I can talk to you about this option and whether this is a benefit to you.

ICSI (Intra-cytoplasmic Sperm Injection)

ICSI is a technique the scientists use to fertilise the egg when conventional insemination is not recommended during an IVF cycle. Indications for use of ICSI include when there are too few sperm or there is poor sperm motility in a sample. The scientist selects the best sperm and then injects it directly into the egg for fertilization.
