 As with the organ sale debate, though, it is not clear why the existence of these risks constitutes an objection to payment, as opposed to an objection to the whole practice of gamete donation (paid or otherwise) since the risks don’t increase as a result of payment (Wilkinson 2013). In response to this, in the case of sperm donation, it could be argued that the scenario where one man produces hundreds of children is much more likely to happen if payment is allowed, as some men seek to become ‘professional sperm donors’. As has been noted, however, it should be possible to neutralise this risk by enforcing donor offspring limits.
