Fertility Treatment IVF and ICSI Treatment

In vitro fertilisation (IVF) and intracytoplasmic sperm injection (ICSI) are advanced assisted reproductive technologies that have helped countless couples and individuals grow their families.

IVF and ICSI Treatment

If you have been trying to conceive without success, or are a solo parent or in same-sex couple, assisted reproductive treatment may help improve your chances of pregnancy. IVF and ICSI are commonly used fertility treatments and can assist with a wide range of fertility challenges. 

What is IVF?

IVF, or in vitro fertilisation, is a fertility treatment where eggs are collected from the ovaries and fertilised with sperm in a laboratory. These eggs and sperm may be provided by you and/or your partner, or accepted from a donor. Once fertilisation occurs and embryos develop, one embryo is transferred into the uterus of the partner intending to carry the pregnancy in the hope of achieving pregnancy.

IVF may be recommended for people experiencing:

  • Blocked or damaged fallopian tubes
  • Endometriosis
  • Ovulation disorders
  • Male factor infertility
  • Unexplained infertility
  • Reduced egg reserve or age-related fertility decline, including from premature ovarian insufficiency

In addition to helping couples overcome infertility, IVF and ICSI are invaluable technologies that enable members of the LGBTQIA+ community and solo parents to experience parenthood through the use of donor sperm/eggs and surrogacy.

What is ICSI?

ICSI, or intracytoplasmic sperm injection, is a specialised form of IVF used to assist fertilisation. Instead of leaving sperm and eggs to fertilise on their own accord in the laboratory dish, a highly skilled embryologist will select a single sperm and inject it directly into each mature egg.

ICSI is commonly used when there are concerns about low sperm count, low sperm motility, low sperm morphology or when surgical sperm specimens are used, although it may also be recommended in other situations such as previous poor outcomes with standard IVF insemination or if preimplantation genetic testing is required. If you are having a baby with the help of a sperm or egg donor, ICSI may be the most appropriate technique after the donor eggs or sperm have been thawed. 

IVF and ICSI follow similar treatment steps, with the main difference occurring during fertilisation in the laboratory.

The IVF and ICSI process

Every fertility journey is different, and your treatment plan will be tailored to your individual circumstances. While treatment can vary slightly, IVF and ICSI generally involve several key stages.

1

Fertility assessment and planning

Before making her treatment recommendations, Dr Anna will review your fertility and medical history, and any previous investigations. She may organise additional fertility tests to better understand factors affecting conception and to help guide your treatment plan.

This is also the perfect opportunity to discuss your goals, treatment expectations, and any questions or concerns you may have.

2

Ovarian stimulation

During an IVF or ICSI cycle, hormone medications are used to stimulate the ovaries of the individual providing the eggs to grow multiple eggs. This increases the number of eggs available for fertilisation and may improve the chance of creating healthy embryos.

Close monitoring will be provided throughout this stage using blood tests and ultrasound scans to assess how the ovaries respond to treatment. 

3

Egg collection

Once the follicles in which the eggs develop reach a certain size, a trigger injection will be administered and then approximately 36 hours later, a minor procedure called the egg collection or egg retrieval is performed. This procedure is usually carried out under light sedation and involves collecting eggs from the ovaries using ultrasound guidance through the vagina.

Most people can return home on the same day, with symptoms of mild cramping, bloating, and fatigue resolving within the week.

4

Fertilisation and embryo development

In conventional IVF, eggs and sperm are combined in a special culture medium in an embryology lab to allow fertilisation to occur naturally. This requires the sperm to swim to the egg and burrow through its outer layers.

In ICSI, a single sperm is carefully injected into each mature egg to assist fertilisation by an embryologist.

The resulting embryos are monitored over 5-6 days as they develop in the laboratory. If you have chosen to undertake preimplantation genetic testing (PGT), a few cells are biopsied from the outer layers of each embryo and sent for genetic analysis. PGT is available to screen for aneuploidy, monogenic conditions, and structural rearrangements in chromosomes; Dr Anna can recommend which test will be most valuable for you.

5

Embryo transfer

One embryo is selected and transferred into the uterus of the partner carrying the pregnancy by performing a speculum exam, and then using a thin catheter to pass the embryo through the cervix up into the uterus. This is usually a quick procedure that does not require anaesthetic, and most people can expect to return home the same day. 

Additional suitable embryos may sometimes be frozen for future use.

6

Pregnancy testing

A blood test is performed around two weeks after embryo transfer to determine whether pregnancy has taken place.

Understanding IVF success rates

IVF and ICSI success rates vary between individuals and are influenced by many factors, including age, egg quality, sperm health, embryo development, and underlying fertility conditions.

While IVF and ICSI can significantly improve the chance of pregnancy for many people, treatment does not guarantee success. Dr Anna believes in providing realistic, evidence-based guidance while supporting you through each stage of treatment.

Frequently Asked Questions

In standard IVF, eggs and sperm are combined in a laboratory dish and allowed to fertilise through the natural process of a sperm cell finding the egg and penetrating its outer shell. In ICSI, a single sperm is injected directly into an egg to assist fertilisation. ICSI is often recommended over IVF when there are significant male fertility concerns, use of frozen eggs, PGT, or previous poor fertilisation with standard IVF cycles.

A typical IVF or ICSI cycle usually takes around two to six weeks from the start of ovarian stimulation medication to pregnancy testing, although timing can vary depending on your treatment plan and individual response.

The number of IVF cycles taken before achieving pregnancy varies from person to person and depends on factors such as age, the presence of a fertility condition, egg and sperm quality, and successful embryo development. Some people achieve pregnancy in their first cycle, while others may require multiple attempts. Dr Anna will discuss your individual circumstances and help you understand what to expect throughout treatment.
