Ideally semen samples should be produced on-site at TDL’s Patient Reception at 76 Wimpole Street, London.
Patients should abstain from ejaculation for 2–3 days before the test (but no less than 2 days and no longer than 5 days). This requirement is important for semen analyses to ensure reliability of results. It is possible that samples that do not comply with guidelines for abstinence and collection may not be able to be processed.
All semen samples must be produced directly into the sterile containers provided by TDL.
All containers are weighed and batch tested for sperm cytotoxicity. In exceptional circumstances when semen samples are produced off-site, these must be delivered to an Andrology member of staff within 45 minutes of collection. Samples can only be accepted for processing by the Andrology Department in containers provided by TDL.
All semen samples must be accompanied by a completed 'Information Form For Patients Producing Semen Samples'.
