Māori Scholarship could revive rare fertility treatment

A Victoria University of Wellington researcher hopes to improve the success of a fertility treatment that’s rarely used in New Zealand but may potentially provide a safer alternative to current artificial reproductive technologies (ART).

Matire Ward of Te Matarahurahu hapū and Te Kotahitanga Marae in Kaikohe has just been granted a Māori Health Research PhD Scholarship, valued at $113,791, in the Health Research Council of New Zealand’s 2019 Career Development Awards. She will be working under the supervision of Dr Janet Pitman, who focuses on factors that make a good egg.

Ward aims to improve the process of in vitro maturation (IVM), in which eggs are retrieved while still at an immature stage and brought to maturity in the laboratory (in vitro). The process differs from conventional in vitro fertilisation (IVF) which utilises medications to bring a patient’s eggs to maturity before they are removed from the ovary.

Ward claims that IVM is safer than conventional IVF as the treatment doesn’t rely on ovarian stimulation which may result in ovarian hyperstimulation syndrome (where ovaries become swollen and painful). However, the use of IVM in fertility clinics remains controversial due to the reduced quality of embryos derived from in vitro matured eggs. For this reason, the practice is still rare in New Zealand, with the first baby only conceived in 2013.

"The main issue is that current IVM methods produce lower-quality embryos. We're taking an immature egg from its natural environment and putting it in this foreign environment in the lab," says Ward.

The secret to improving the treatment’s success could be in mimicking, within a Petri dish, the natural physical environment of ovarian follicles in which eggs would normally mature, she says.

As a follicle matures, an area within it fills with fluid, says Ward. The nutrients, including glucose, carbohydrates, hormones, and growth factors present in this fluid are transferred to the egg by its surrounding support cells. This transfer is critical for optimal egg development and maturation.

When cells are cultured in a dish in the lab, these nutrients are provided at concentrations very different to what is found in follicular fluid.

Using cow’s eggs for her investigations, Ward will prepare and test nutrients at concentrations similar to that of follicular fluid. She will then investigate the key molecular and metabolic pathways that are altered when immature eggs are exposed to these nutrients, in order to develop an improved IVM system that produces high-quality embryos.

Ward says refining this therapy may give another treatment option to couples concerned about, or at risk of, hyperstimulation syndrome.

She also aims to have conversations with Māori about the use of ART and how her research might mitigate commonly-held concerns about fertility treatments. “While Māori opinion on these types of therapies is conservative, it’s of upmost importance to all Māori people that their whakapapa is continued in a way that regards tikanga,” she adds.

Ward is the first in her family to undertake tertiary education, but says she is quite used to being surrounded by science. "My mum is a science technician and throughout my childhood, I would often accompany her to the laboratory.”

She says this scholarship will be a foot in the door to get into postdoctoral research involving assisted reproductive technologies in women. “I hope to continue researching in fertility clinics worldwide to expand my research capabilities and then come home to establish myself as a leading reproductive health researcher joining the few Māori women in this research field.”

Matire Ward is one of 19 researchers to receive a 2019 HRC Māori Health Research Career Development Award.

Mr Stacey Pene, the HRC’s senior manager of Māori Health Research Investment, says these Awards are key to building capacity and capability within the Māori research workforce.

“Māori researchers are tackling complex scientific questions and public health issues that will improve Māori health and wellbeing, and benefit New Zealand as a whole. We’re incredibly proud to support researchers who are making a significant contribution to knowledge and a genuine difference to their communities,” he says.

International Art Centre: Rare Goldie Landscape Expected To Fetch $150,000

When Evening Shadows Fall is one of four works by Goldie included in a sale of Important and Rare Art at the International Art Centre in Parnell on November 28. Goldie painted only a handful of landscapes, concentrating mainly on indigenous portraits, which earned him a global reputation as NZ’s finest painter of respected Māori elders (kaumātua). More

Mark Stocker: History Spurned - The Arrival Of Abel Tasman In New Zealand

On the face of it, Everhardus Koster's exceptional genre painting The Arrival of Abel Tasman in New Zealand should have immense appeal. It cannot find a buyer, however, not because of any aesthetic defects, but because of its subject matter and the fate of the Māori it depicts. More
