The Human Fertilisation and Embryology (Statutory Storage Period) Regulations 1991
These Regulations provide that where a person who has provided gametes becomes infertile, or is likely to, the gametes may (in the circumstances laid down in the Regulations) be stored for a period longer than the period of 10 years for which gametes may ordinarily be stored. The storage period can be extended in this way only if the person who provided the gametes was aged under 45 at the time.
