New rules to protect frozen sperm, eggs and embryos

Date issued: 8 June 2004 - Extracted from HFEA publication

The HFEA has announced strict new guidelines to protect the safety of frozen sperm, eggs and embryos stored at fertility clinics throughout the UK. The guidelines have been produced following an HFEA review into a small number of incidents where inadequate temperature levels in storage vessels led to the irretrievable loss of patients’ stored material.

To improve safety for patients, by the end of June 2005 all clinics storing frozen sperm, eggs and embryos are expected to ensure:

	Effective alarms and monitoring systems are fitted to storage vessels
	The alarm system includes a process to alert staff if problems occur outside normal working hours - like auto-dialling of staff’s home telephone numbers or links to a hospital’s fire alert system
	Formal emergency procedures are in place for dealing with a freezer incident - including adequate spare storage vessels for transferring samples
	A staff ‘on-call’ system is in place so that there is always somebody available to carry out these emergency procedures

As an additional measure the samples of patients whose fertility has been impaired by medical treatments, like those used to treat cancer, should be divided between different storage vessels.

Angela McNab, HFEA Chief Executive said:

"We have to make sure we take every step possible to safeguard stored material in clinics. For cancer patients in particular, this material is so precious because it can be their only chance of having children. Patient safety is our top priority at the HFEA and we work constantly with infertility clinics to improve it.”

These storage guidelines are the latest in a series of HFEA initiatives to improve patient safety at UK fertility clinics by sharing information between clinics. Earlier this year the HFEA formalised its incident alert system which involves the HFEA issuing all clinics with anonymous details of adverse incidents to help avoid mistakes being repeated.

Notes to editors

Cancer patients are encouraged to store their sperm, eggs or embryos before undergoing treatment, like chemotherapy or radiotherapy, which can leave them infertile.

Sperm, eggs and embryos are stored in liquid nitrogen at -196°C in storage vessels called dewars.

The HFEA was set up in August 1991 as part of the Human Fertilisation and Embryology Act 1990. The HFEA’s principal tasks are to license and monitor clinics that carry out in vitro fertilisation (IVF), donor insemination (DI) and human embryo research. The HFEA also regulates the storage of gametes (eggs and sperm) and embryos.
