Request forms for IUI and DI analysis are provided by the relevant clinicians at appointments.
The fertility laboratory operates an appointment only system for the analysis of semen samples.
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.
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 means 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.
All additional test examinations are carried out when appropriate by the biomedical scientist as part of the diagnostic process. This may include
The laboratory currently follows the WHO 2010 Guidance, 5th edition.
The WHO updated their guidance in 2021 from the 5th to 6th edition for semen analysis. Main changes in reporting include morphological assessment to incorporate specific morphological issues.

The laboratory is HFEA accredited.
