Policy & Guidelines

We are committed to providing the Government and other policy makers with accurate evidence based opinion.

The following are policy and guidelines of interest to our organisation:

Statement on Openness in Animal Research (8/9/2015)

The British Andrology Society supports the use of animals in research when properly regulated and when no alternatives are available. We actively support progress towards a reduction in the use of animals by refining experiments and developing new ways to minimise the use of and replace animals wherever possible.


The British Andrology Society endorses the Society of Biology’s position on the use of animals in scientific research, which outlines both the benefits that come from using animals in research, and the commitment to reduce the use of animals in research as technology allows. For details, see:


The British Andrology Society has signed the Concordat on Openness on Animal Research, a commitment to provide the public with accurate and up-to-date information about how animals are used in research, the role they play in scientific discovery and the development of new medical treatments.

For details see:

The retention and storage of pathological records and specimens (2/6/2015)

The guidelines for retention and storage of pathological records and specimens have recently been revised and issued by The Royal College of Pathologists and the Institute of Biomedical Science. The revised guidance can be accessed via their website:

Statement on the use of CASA (04/08/2014)

The BAS is aware that the use of computer assisted sperm analysis (CASA) is becoming more common in UK andrology laboratories, as such we are issuing this guidance statement alongside a similar one from our colleagues in the ABA.


Whilst the BAS supports technological advances in semen analysis, it is essential that full process validation and verification is performed on any systems being brought into clinical use to ensure that their performance provides at least the same level of accuracy as existing methods. In this case the manual motility scores and counts on an Improved Neubauer chamber as recommended in WHO 2010 and as part of the ESHRE~BAS Basic Semen Analysis Course.  


CASA systems have the potential to reduce the time taken to assess motility and concentration by providing a rapid and automated assessment of the parameters of sperm motion and the concentration of sperm in a semen sample. Local validation against the standards as outlined above is expected as a minimum for any CASA system, and its ongoing use and validation will always require well-trained Andrology staff.


Given that sperm are highly sensitive to temperature, the BAS does not endorse the assessment of sperm motility at room temperature and algorithmic extrapolation of what the motility might be at 37ºC on the basis of a room temperature manual or CASA analysis.  

2008 Donor Guidelines

The 2008 Donor Guidelines are a consensus document that set down the screening steps necessary for any sperm or egg donor to be accepted and released for treatment within the UK.

Post-Vasectomy Semen Analysis Guidelines

On 15th April 2016 new Laboratory Guidelines for Post-Vasectomy Semen Analysis were published. These are now available via this link


The 2002 Post-Vasectomy Semen Analysis Guidelines are still viewed by many worldwide as the basis document for assessment of a successful vasectomy procedure through semen analysis. They have recently been updated by the Society jointly with the ABA and BAUS (please see separate link above). The 2002 guidelines are still available for download below but should now only be read in association with the 2016 Guidelines.
