This article is a personal perspective on male infertility, a condition that is not only extremely prevalent but also a major reason for couples to resort to ART. The introduction of ICSI as a form of facilitated fertilization had a revolutionary impact on our capacity to treat cases of male infertility associated with severely compromised semen quality. However, the widespread use of this technique is also thought to pose risks in terms of the incidence of miscarriage, the health and wellbeing of the offspring and perpetuation of the infertile phenotype into future generations...

The derivation of gametes from patient-specific pluripotent stem cells may provide new perspectives for genetic parenthood for patients currently facing sterility. We use current data to assess the gamete differentiation potential of patient-specific pluripotent stem cells and to determine which reprogramming strategy holds the greatest promise for future clinical applications. First, we compare the two best established somatic cell reprogramming strategies: the production of induced pluripotent stem cells (iPSC) and somatic cell nuclear transfer followed by embryonic stem cell derivation (SCNT-ESC)...

Recently, American colleagues called for a systematic collection of anonymized data on how many embryos and foetuses are deselected per institution per year, and for which conditions. These authors argued that if this information would be reported to a government agency or international body, the information would provide a baseline against which jurisdiction-specific trends in selection could be assessed. People who have disabilities, together with other key stakeholders, laypeople and experts, would then be in a position to assess the social impact of human selecting technologies and to make recommendations for action to mitigate negative effects as appropriate...
