Low sperm count following ICSI conception – Expert reaction

Sarah-Jane O'Connor posted in on October 6th, 2016.

A new study of men who were conceived in the 1990s using a now common fertility treatment has found they have lower-than-average fertility – suggesting the treatment passed the fathers’ fertility issues onto the sons. The 54 young men, now aged 18-22, were conceived using intracytoplasmic sperm injection (ICSI) – a method used for men […]

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 […]

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 […]

First steps towards ‘The Pill’ for men – experts respond

John Kerr posted in on August 17th, 2012.

New research has shown a promising avenue for creating a male version of ‘The Pill’, but independent experts caution that an effective contraceptive agent for males will still be some years away. Researchers have identified a compound that may offer the first effective and hormone-free birth control pill for men. The study, published in the […]

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 […]
