Our Expert Biomedical Scientist is available by contacting the laboratory directly- 01332 785710 for questions related to sample processing, collection and reference ranges.

How do I complete a request form?

Semen analysis (White) and Post vasectomy analysis (Green) request forms are available from our pathology stores Tel: 01332 785581

Request forms for IUI and DI analysis are provided by the relevant Clinicians at appointments. 

Is there an out of hour’s service or shift system?

See opening times above.

Are there any instructions for transportation of samples, including any special handling needs?

The fertility laboratory operates an appointment only system for the analysis of Semen samples. Patients are requested to call 01332 785643 to arrange an appointment.

It is preferably for samples to be produced on site (dedicated rooms available)

Samples that are produced at home must be provided in a specific container (available from the fertility unit) and brought to the unit at the arranged appointment time. Samples must be received within 30 minutes of production.

Is there any information on those key factors which are known to affect the performance of the test or the interpretation of the results?

Semen Sample pots provided by the fertility unit are Cytotoxicity tested by the Andrology laboratory. It is essential that these containers are used. We cannot accept samples in any other containers.

It is imperative that samples arrive in the department soon after production. Time limits are set at 30 minutes post production for semen analysis and for post vasectomy analysis to allow us to process the sample within 1 hour of production.

Abstinence (the length of time since the last ejaculate by masturbation or intercourse) should be between a minimum of 2 days and preferably up to a maximum of 7 days; outside of this range quantity and/or quality of the sample may be affected.

It is essential that the whole sample is collected. Samples that are only partially collected will not be tested. This is to avoid the reporting of inaccurate results, as sperm are not ejaculated evenly throughout the seminal fluid.

Samples that are produced at home should be kept at body temperature. Excessive heat/cold will affect the diagnostic interpretation of results.

What are the time limits for requesting additional examinations?

All additional test examinations are carried out when appropriate by the Biomedical Scientist as part of the diagnostic process. This may include

Vitality Test

Anti-sperm Antibody Testing
