New Fertility Treatment Now Available in New Zealand
New Fertility Treatment Now Available in New Zealand
Women with polycystic ovarian disease or
who are undergoing cancer treatment are set to benefit from
a fertility treatment previously unavailable in New
Zealand.
The technique, called In Vitro Maturation (IVM), involves the removal of the eggs from an ovarian follicle, allowing them to mature in the laboratory for one to two days and then fertilised in the same way as IVF. This offers an alternative to conventional In Vitro Fertilisation (IVF) whereby mature eggs are collected and fertilised straight away.
Dr Simon Kelly of Fertility Associates, who will be introducing this service to New Zealand, says that this will mean pregnancy with their own eggs will be possible for some 5% of women for whom conventional IVF treatment is more challenging.. “IVM is commonly used for women who have polycystic ovarian disease or who may be about to undergo treatment for cancer where it is known the IVF drugs may stimulate the growth of the existing cancer,” Dr Kelly said. “While we expect the initial numbers to be quite low, we do expect to see more women opting for IVM as the process improves and understanding of IVM increases.”
IVM has huge potential as the technique of maturing a woman’s eggs outside of her body continues to improve. It has the potential to minimise the duration, cost and side effects of IVF drugs, and to relieve women of the time consuming and intrusive nature of blood tests and ultrasound scans leading up to IVF itself.
Dr Kelly believes that as more fertility clinics gain experience with IVM, the pace of improvement will accelerate.
IVM has been used overseas for around 12 years but approval for use in New Zealand has been granted by the Ministry of Health under the Human Assisted Reproductive Technology (HART) Act 2004 this week.

About the HART Act – Human Assisted
Reproductive Technology Act 2004
The practice of
fertility treatment where sperm, eggs or embryos spend time
outside the human body is governed by the Human Assisted Reproductive Technology
(HART) Act 2004.
The Act starts by listing important
principles, including the health and well being of children
conceived using fertility treatments, the health safety and
dignity of future generations, the health and well being of
women having treatment, informed consent, consideration and
respect for the needs, values and beliefs of Maori, and
consideration and respect for ethical, spiritual and
cultural perspectives in society.
In addition, the Act
states that offspring conceived through the use of donor
sperm or donor eggs should be made aware by their parents of
their genetic origins, and be able to secure information
about the donor and his or her identity.
About
Dr Simon Kelly
Dr Simon Kelly graduated from the
University of Otago and then completed postgraduate training
in Obstetrics and Gynaecology both in Auckland and the
United Kingdom.
He subsequently undertook two
fellowships in reproductive medicine firstly as a lecturer
to Professor Stuart Campbell at St George's Hospital Medical
School in London, UK and then most recently with Professor S
L Tan at McGill University in Montreal, Canada. His main
areas of interest are the application of advanced ultrasound
technology to infertility management, in vitro maturation of
immature oocytes collected from unstimulated ovaries and
aspects of fertility preservation.
Apart from his
fertility interests, Simon also has a private obstetric and
gynaecology practice based at Fertility Associates. He
conducts clinics in Auckland, East Auckland and the North
Shore.
About In Vitro Maturation (IVM)
In
Vitro Maturation (IVM) of eggs is a promising new technology
that may function as another option to traditional IVF. The
benefits of IVM are patient convenience, patient safety
because drugs are not used, and reduction or no cost of
drugs. IVM involves collection of immature eggs from
patients, these are then matured in the laboratory, and may
then be used in standard IVF / ICSI procedures.
Using
immature eggs in the IVM process requires extensive
laboratory work and is more time consuming than traditional
IVF.
IVM is a well established technique for many
animals, and is used commercially in cattle breeding.
