Science Alert: Experts Respond

Sperm derived from stem cells – Experts reaction

John Kerr posted in on February 26th, 2016.

Scientists in China have created functioning sperm from mice stem cells in the laboratory. To accomplish this feat, the researchers coaxed mouse embryonic stem cells to turn into functional sperm-like cells, which were then injected into egg cells to produce fertile mouse offspring. The research, published in Cell Stem Cell, provides a platform for generating […]

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 […]

Fertile mouse eggs created from stem cells – experts respond

John Kerr posted in on October 5th, 2012.

Japanese researchers have turned mouse stem cells into germ cells that give rise to eggs in living mice, which then produced viable offspring via in vitro fertilisation. This research, which mirrors work already done with sperm, may open the door to new insights into female germ cells and provide new leads for treating some forms […]

UK experts on Nature stem cell and infertility genes paper

Peter Griffin posted in on October 29th, 2009.

Scientists have used embryonic stem cells to create the precursors of human sperm and eggs. They hope the techniques may be used to improve the effectiveness of infertility treatments. Our colleagues at the Science Media Centre in the UK wrapped up comment on the paper in Nature. The full title of the paper is: Human […]
