 The first is selection against donors posing a threat to the physical wellbeing of pregnant women. This form of selection is ubiquitous such that the barring of donors with sexually transmissible diseases such as HIV, hepatitis B and syphilis is mandated by national and international guidelines on gamete donation (see, for example HFE Act 2008: s. T52 – see Other Internet Resources). This motivation for selection is widely seen as morally unproblematic and will, for this reason, be largely ignored here.
