Looking for genetic relatives in genetic databases is harmful and wrong
20 May 2019 - by Professor Guido Pennings
More and more people are using DNA testing websites. The curiosity about one's ancestry seems to be growing, especially in the USA. In doing so, millions of people are giving away all rights to their genetic information without much concern about what can or will be done with it... [Read More]

21 August 2006 - by Professor Guido Pennings
Egg sharing remains a highly controversial procedure. The discussion on whether or not egg sharing in return for a free or reduced IVF cycle constitutes a kind of payment has been going on since the very beginning of the practice. However, from an ethical point of view, it might be... [Read More]
Sperm and egg donation: a system of need-adjusted reciprocity

All kinds of solutions have been proposed, including increased payment. Another solution, namely egg sharing, has been criticised by some as morally dubious. In the meantime, as the SEED...

A 'social compensation tax' for social sexing
11 April 2005 - by Professor Guido Pennings
The recommendations of the recent report by the House of Commons Science and Technology Committee in the UK have stirred up the discussion on social sex selection. Over the years, the discussion on sex selection has been seriously hampered by the high emotional engagement of the participants. As a consequence... [Read More]
