About Dr Anthony Marren CREI

Understanding the emotional journey couples endure when they have difficulty conceiving or recurrent pregnancy loss is essential to my approach.

Taking the time to truly listen during consultations allows me to provide the support my patients need. Providing clear and helpful information is a priority, empowering couples to make informed decisions about their fertility treatment.

My Qualifications

My Qualifications

After obtaining my medical degree from the University of Newcastle, I was awarded the Faculty of Medicine Medal, recognising academic excellence throughout the B. Medicine program. I then went on to complete a Master of Medicine in Reproductive Health and Human Genetics at the University of Sydney.

My training in Obstetrics and Gynaecology at Sydney’s Royal Prince Alfred Hospital led to becoming a Fellow of the Royal Australian and New Zealand College of Obstetricians and Gynaecologists. I am also a certified sub-specialist in reproductive endocrinology and infertility (CREI) after an additional three years of advanced training.

Male and Female Fertility Treatment

Offering comprehensive, evidence-based fertility treatments for both women and men is at the heart of my practice. I bring expertise as a laparoscopic surgeon, specialising in complex procedures such as endometriosis and fibroid surgery. 

My special interests include the investigation and management of recurrent pregnancy loss, recurrent implantation failure, and pre-implantation genetic testing. I am also experienced in providing fertility preservation options for individuals preparing for chemotherapy, ensuring personalised care during challenging times.

Who Is a Candidate for Fertility Treatment?

Any individual regardless of relationship status, gender, or sexual orientation who wishes to achieve a pregnancy or take steps to preserve their fertility has the right to a fertility assessment and treatment.

How Long Does Fertility Treatment Take?

Those treatments that hopefully result in a successful pregnancy (e.g. ovulation tracking, ovulation induction (OI), intrauterine insemination (IUI), and in vitro fertilisation (IVF) will typically take 1-month.

Egg freezing cycles typically will take 2-weeks.

Cycles that require chromosome/ genetic testing of embryos and then their subsequent transfer will take approximately 2-months.

What Are the Success Rates of IVF?

Depends on a number of factors such as:

  1. Female age;
  2. Male age;
  3. Underlying cause of infertility;
  4. Duration of infertility;
  5. Number of prior unsuccessful cycles.

How can I prepare for my first consultation?

A GP referral will provide a summary of your history and any investigations performed. It also enables a Medicare rebate for the consultation.

Please obtain any summaries from any prior fertility cycles. Especially the MONITORING and EMBRYOLOGY pages. 

Consider what you would like to achieve from the first consultation and write down any questions you have.

What types of reproductive surgeries are available for fertility issues?
  • HYSTEROSCOPY is a minimally invasive procedure that allows us to diagnose and treat conditions found within the uterus e.g. polyps, fibroids, and adhesions (Asherman syndrome).
  • LAPAROSCOPY is a minimally invasive procedure that allows us to diagnose and treat conditions found within the pelvis e.g. endometriosis, adhesions, and fibroids.
  • LAPAROTOMY is an open procedure that allows us to treat conditions such as large fibroids that are difficult to do with laparoscopy.
How is PGS different from PGD?

PGT = pre-implantation genetic testing of embryos.

Embryos have 5-10 cells removed at the day 5 - 6 stage (Blastocyst).

The genetic material within these cells is amplified (copied multiple times). This enables the chromosome and genetic structure of the embryo to be assessed.

  • PGT-A (aneuploidy) is a screening test that enables us to determine if the embryo has the correct number of chromosomes (euploid) or not (aneuploid).
  • PGT-SR (structural rearrangement) is a test that enables us to determine if the embryo has a rearrangement of chromosome material (most commonly translocation).
  • PGT-M (monogenetic) is a test that enables us to determine if the embryo is affected by a specific genetic condition e.g. cystic fibrosis.
