Science Alert: Experts Respond

Fertile eggs created from mouse stem cells – Expert Reaction

Sarah-Jane O'Connor posted in on October 18th, 2016.

Japanese researchers have successfully produced functional mouse eggs entirely in cell culture using stem cells. Their study, published today in Nature, resulted in healthy and fertile mouse pups. The researchers say being able to grow viable mouse eggs in the lab will provide clues to aid the development of similar systems in other species. More information […]

UPDATED: World’s first ‘three-parent’ baby – Expert Reaction

Sarah-Jane O'Connor posted in on September 28th, 2016.

News broke overnight that a baby born in April was the result of a new technique using DNA from three people. The Jordanian parents contacted researchers at New York’s New Hope Fertility Center after discovering the mother had a rare mitochondrial disease – Leigh syndrome – which she had passed on to two children, both […]

Embryo research hits ethical barrier – Expert Reaction

John Kerr posted in on May 5th, 2016.

Scientists have broken through a technical barrier in human embryo research and now face an ethical one. Two separate studies published in Nature and Nature Cell Biology today report on new methods allowing human embryos to cultured and studied in Petri dishes for as long as 13 days. Previous studies have struggled to keep embryos […]

Sperm banking for young men – Expert reaction

John Kerr posted in on June 26th, 2015.

A bioethicist’s call for young men to freeze their sperm for future use has received a chilly reception from independent experts. Writing in the Journal of Medical Ethics, Dr Kevin Smith, from Abertay University in Dundee, suggested state-sponsored sperm-banking as way of avoiding the complications of older fatherhood. Younger men could freeze their healthier sperm […]

Safe IVF in New Zealand – experts respond

Laura Goodall posted in on November 6th, 2014.

New Zealand and Australia are world leaders when it comes to safe In Vitro Fertilisation (IVF), confirms a new report that summarises the latest data from the two countries. The authors of the Assisted Reproductive Technology in Australia and New Zealand 2012 report analysed data about IVF cycles undertaken in 2012 and the resulting babies born. They found that rates of multiple […]

IVF and mental retardation, autism risk – experts respond

Dacia Herbulock posted in on July 3rd, 2013.

A Swedish study has found that IVF treatment is not associated with increased risk of developing an autistic disorder, however it was associated with a small but statistically significantly increased risk of mental retardation. The authors note that the prevalence of these disorders was low, and the increase in absolute risk associated with IVF was […]

Time-lapse images of embryos used to boost IVF success

Dacia Herbulock posted in on May 17th, 2013.

New research describes a breakthrough in IVF technology that proponents claim will significantly increase live birth rates in fertility clinics. The technique uses precision time-lapse imaging to more accurately distinguish developing embryos with normal and abnormal numbers of chromosomes. The study found that embryos with too many or too few chromosomes typically reach specific growth […]

IVF pioneer Sir Bob Edwards dies, age 87

John Kerr posted in on April 11th, 2013.

Robert Edwards, a pioneering fertility scientist whose ground breaking research lead to the success of in-vitro fertilisation, died Wednesday at age 87. Prof Sir Robert (Bob) Edwards, working with Dr Patrick Steptoe, is credited with the development of in vitro fertilization, or IVF, which resulted in the birth in 1978 of the world’s first ‘test […]

In Vitro Fertilisation (IVF) explained

Peter Griffin posted in on July 24th, 2008.

What is IVF? In vitro fertilisation is a form of assisted reproductive technology which involves the combination of human eggs and sperm outside of a woman’s body. Prepared ova and sperm cells are cultured together in the laboratory overnight. The resulting fertilised eggs are allowed to develop to the 8-cell stage – typically 2-3 days […]

30 years of In Vitro Fertilisation (IVF)

Peter Griffin posted in on July 24th, 2008.

Three decades ago today, on 25 July 1978, Louise Brown, the world’s first ‘test-tube’ baby was born. We asked New Zealand reproductive health experts to reflect on how far the science has come, and what may lie ahead.
