Semen fertility investigations



Sperm morphology stain

  • The department offers a range of semen infertility investigations which include:
    • sperm concentration (sperm count)
    • sperm motility
    • sperm morphology (normal forms)
    • volume
    • pH
    • viscosity
  • Any other infertility tests should be referred to a specialist andrology unit, e.g. Bristol.
  • As these samples are very time-consuming to process, an appointment system is operated to ensure sufficient time can be allocated to carry out the analysis.
  • Appointments are usually arranged for weekday mornings (Monday to Friday).
  • To book an appointment patients should phone between 09.00am and 12.00 noon Monday to Friday on Telephone number 0300 422 4200.
  • A room is available on site, if required, for patients to use to produce a sample.
