UK sperm donations being exported despite 10-family limit

Exclusive: Legal loophole means there is no restriction on making sperm or eggs available for additional fertility treatments abroad

• You feel a bit mass-produced': donor-conceived people on the export of UK sperm

Sperm donated in the UK is being exported and can be used to create large numbers of children across multiple countries, contradicting a strict 10-family limit that applies in the UK, experts warn.

A legal loophole means that, while a single donor can be used to create no more than 10 families in UK fertility clinics, there are no restrictions on companies making sperm or eggs available for additional fertility treatments abroad.
