Mitochondrial replacement techniques, Mexico and the legal unknowns

24 April 2017 - by Dr César Palacios-González

It is not every day that we can examine the details of the first use of a new reproductive technology. But the first live birth of a baby following the use of a mitochondrial replacement technique (MRT) in IVF last year gives a window into just this. The case – with procedures carried out in both the US and Mexico – also raises legal questions... [Read More]

Regeneration of oocytes from discarded genetic material: will this double IVF success rates?

28 November 2016 - by Dr Philip Lewis and Professor Daniel Brison

A major factor limiting the effectiveness of IVF is the availability of high-quality egg cells from a patient. But new research suggests that the use of polar bodies might create two oocytes for the price of one... [Read More]

Old drugs: new eggs?

07 November 2016 - by Bethany Muller and Dr Roger Sturmey

Ten years ago, the claim that treatment with cancer drugs can 'grow new eggs' would have been met with incredulity. But a recent study has raised the possibility that ovarian stem cells may be capable of providing new eggs in later life... [Read More]

Semen quality of ICSI-born males – not as bad as we thought

10 October 2016 - by Professor Allan Pacey

The finding that men who were conceived as a result of ICSI have lower sperm counts is not surprising, but the good news is that they are not as low as might have been expected... [Read More]

Shortage of organs for transplantation – is more research on human–animal chimeras the right approach?

12 September 2016 - by Dr Silvia Camporesi and Giulia Cavaliere

By focusing all our attention on the ethics of human–animal hybrids, we may be overlooking non-technical solutions to the short supply of human organs for transplantation... [Read More]

Turning back the ticking clock: Could we? Should we?

01 August 2016 - by Dr Roger Sturmey

Reports that scientists in Greece have rejuvenated ovaries in perimenopausal women is potentially very exciting. However, there remain significant questions about this research... [Read More]

Matching mitochondrial and nuclear DNA: Much ado about nothing?

18 July 2016 - by Dr Dusko Ilic

A match of mitochondrial and nuclear genomes apparently affects healthy ageing in mice. But key questions need to be answered before stirring up implications for human mitochondrial replacement therapies... [Read More]

Can women put motherhood on ice?

27 June 2016 - by Dr Lucy Freem

Pre-pubertal ovarian tissue preservation – are we pushing the boundaries too far?

11 April 2016 - by Dr Edgar Mocanu

Oncofertility services allow some women to cryopreserve oocytes, embryos or ovarian tissue in order to protect their ability to have a family when faced with malignancy and adjuvant therapy. However, to date, fertility cryopreservation had very little to offer young, pre-pubertal girls... [Read More]

Beating the biological clock - should you freeze your eggs?

26 October 2015 - by Kirsty Oswald

Will egg freezing enable women to take full reproductive control and beat the biological clock? Or is it just another way to tell women they can't have a career and a family? These were some of the questions tackled at PET's recent event 'Beating the Biological Clock: should you freeze your eggs?'... [Read More]

The case against human cloning

28 September 2015 - by Brendan Foht

Genetic ties, social ties and parental responsibility

14 September 2015 - by Dr Reuven Brandt
