Incidence of and indications for sperm donor restriction - analysis of patients continuing treatment: a retrospective single-centre study.

Donor restriction due to suspected/confirmed disease risk is relatively frequent. This affected a relevant number of women (around 800), of whom 172 (approximately 20%) had to decide whether or not to use these donors further. Although donor screening is being performed thoroughly, there remain health risks for donor children. Realistic counselling of all stakeholders involved is necessary.
