Sperm DNA test

A specialised male fertility test to analyse sperm quality

The Lister Fertility Clinic offers the SpermComet® test to examine DNA damage that may be behind unexplained infertility

About

Sperm DNA damage, also known as DNA fragmentation, can be the cause of failed fertility treatment, low pregnancy rates and even miscarriage. The SpermComet® test checks the health of your sperm DNA. Results can determine the best fertility treatment to increase your chance of having a healthy baby.

Need to know

  • What happens icon plus

    If you and your partner are having trouble getting pregnant or are considering fertility treatment, the SpermComet® test might be the right first step. It can be done in addition to a normal semen analysis. Where a normal semen analysis looks at sperm count, mobility, shape and size, the SpermComet® test analyses your sperm at a molecular level. You'll produce a sample of semen, which is frozen and sent to a dedicated lab for testing. The lab will look for DNA damage in individual sperm. We'll have the results back within seven days and your consultant will discuss these with you.
  • How to prepare icon plus

    Your consultant will explain the test to you and answer any questions you may have. Ideally you should abstain from sexual activity for three to five days before the test. If you're not comfortable producing a semen sample at the clinic, it might be possible to do this step at home. Your consult will let you know if this is an option.
  • Afterwards icon plus

    Your consultant will review the results of the SpermComet® test with you. These should be available within seven days. If your results show damage to your sperm DNA, your consultant may suggest some healthy diet and lifestyle changes that can improve the quality of your sperm. They'll also be able to recommend the best course of fertility treatment based on your results.
