Older mothers and global/national responsibilities

08 February 2010 - by Professor Naomi Pfeffer

Much of the debate about elderly motherhood has focussed on the anomalous situation of a woman simultaneously qualifying for an old age pension and child benefit. It is an engaging topic, but the discussion needs to be widened to include a consideration of global/national responsibilities: the relationship of a woman who provides an egg to, following its fertilisation, the woman in whom the embryo is implanted....[Read More]

Study shows rapid decline in women's eggs after 30

31 January 2010 - by Maren Urner

The first study to chart the fate of a woman's supply of eggs from conception to the menopause, carried out by researchers of the University of St Andrews and Edinburgh University, UK, shows that the average 30-year-old woman will have just 12 per cent of her original ovarian 'store' of eggs left. The study, published in the journal PLoS ONE, also shows that by the age of 40, only three per cent of the estimated two million eggs a woman is born with are left. The rapid decrease...[Read More]

25 January 2010 - by Ailsa Taylor

Last week BioNews reported that the UK's Human Fertilisation and Embryology Authority (HFEA) had for the first time decided to publish its report and the Licence Committee minutes relating to Grade A incidents, two of which occurred earlier last year at Guy's Hospital Assisted Conception Unit (ACU). It has been brought to our attention that there were a number of inaccuracies in this article. The corrected version of the article is published below:...[Read More]

Unnatural selection?

14 December 2009 - by Helen Keeler

I had wanted to donate my eggs to a woman with fertility problems ever since having children of my own. I frequently tell my three children that I always wanted to be a mother and that every day they make my dreams come true. How wonderful it would be to help make someone else's dreams come true too....[Read More]

14 December 2009 - by Sarah Guy

Embryo donation is not like adoption

11 December 2009 - by Dr Fiona MacCallum

The recent report by the Ethics Committee of the American Society for Reproductive Medicine (ASRM) (1), stating that the use of the term 'embryo adoption' is misleading, addresses a question which has been asked since the first successful donation of an embryo. Should treatment with donated embryos be approached as any other assisted reproductive technology (ART), or should it be seen as another form of adoption? Children conceived through embryo donation do resemble adopted chi..

A link between male infertility and epigenetic disorders in ART babies?

11 December 2009 - by Dr Rosalind M John

The aim of assisted reproductive technology (ART) is to achieve a single most important goal, the birth of a healthy child. ART is responsible for the birth of over 200,000 children each year worldwide. In the most common form of infertility treatment - IVF (in vitro fertilisation) - the woman's eggs are collected and then combined with the man's sperm in a petri dish. The successfully fertilised eggs are then transferred into the woman's womb. In ...[Read More]

Controversial egg modification technique could increase IVF success in older women

15 November 2009 - by Rebecca Robey

A controversial new technique to improve the quality of eggs from older women undergoing IVF is being developed by Japanese scientists. Because the procedure involves using eggs from two women to create a single viable egg for fertilisation, it has sparked a media furore over the potential creation of what have been inaccurately dubbed 'three-parent embryos'....[Read More]

25 October 2009 - by Nienke Korsten

In a debate in the House of Lords of the UK parliament last week, Tory Lord Earl Howe criticised revised regulations that allow for embryos, sperm and eggs to be stored for up to 55 years for prematurely infertile parents.

01 September 2009 - by Dr Jennifer Speirs

Professor Lisa Jardine, the chair of the UK's Human Fertilisation and Embryology Authority (HFEA), has called for a fresh debate on two allegedly controversial aspects of gamete donation, namely the provision of gametes to a known relative of a different generation, and the provision of semen by a man to his sister if she is using a donated egg...[Read More]

The problem with 21st Century Motherhood

17 August 2009 - by Dr Sammy Lee

Did the death of Maria Bousada change public attitudes to the modern phenomenon headlined as 'Oldest Mums'? The world's media certainly made hay and the news reverberated for a few days; and it seems likely that the Channel 4 documentary 'the Worlds Oldest Mums' was rescheduled to screen early to catch the media wave which the death generated. The aftermath, though, of this tsunami seems to have largely been relative indifference....[Read More]

17 August 2009 - by Ailsa Taylor

Many women are risking their chances of being able to have children by leaving it too late, according to Bill Ledger, Professor of Obstetrics and Gynaecology at the University of Sheffield. He told the Daily Telegraph that women who chose to delay motherhood until their 30's and beyond in order to establish their careers were ignoring the implications this could have for their fertility....[Read More]

HFEA calls for debate around payment for sperm and egg donation

27 July 2009 - by Ailsa Taylor

A public debate is urgently needed to decide whether people should be paid for donating eggs and sperm to infertile couples, according to Lisa Jardine, Chairman of the Human Fertilisation and Embryology Authority (HFEA). In an exclusive interview with the Times, Professor Jardine said that the lack of egg and sperm donors in this country was driving couples abroad for fertility treatment in often unregulated clinics, and that the HFEA could potentially consider a reversal of the ban on paymen...[Read More]
