Semen Analysis or Sperm DNA Fragmentation?

Making healthy sperm is complicated and things can go wrong along the way. If you are thinking about starting a family, have been trying for a while, or have experienced miscarriage, it makes sense to take a fertility test to check out the health of your sperm.

Semen analysis is usually the first step men take when looking into their fertility. It provides important information about sperm health, but often that’s not enough. Semen analysis measures your sperm count, motility, and morphology but it does not reveal the quality of the sperm – only a sperm DNA fragmentation test can do that.

Semen Analysis or Sperm DNA Fragmentation?

What’s the difference between Sperm DNA Testing & Semen Analysis?

Sperm DNA fragmentation (SDF) damage provides more information about a man’s fertility than semen analysis alone. Many men who have a normal semen analysis result cannot get their partner pregnant, while lots of men with an abnormal semen analysis result do conceive naturally.

Research shows that 40 percent of the men attending fertility clinics who had a normal semen analysis result, also had a high sperm DNA damage result using our Exact® test. Men with high sperm DNA fragmentation damage:

  • are less likely to get their partner pregnant
  • have double the risk of miscarriage
  • are less likely to be successful with fertility treatment, such as IVF

Our range of SDF tests are the most accurate available having the highest sensitivity, specificity and predictive power when compared to other sperm DNA tests.

A Sperm DNA Fragmentation (SDF) test will tell you:

Your sperm DNA provides 50% of the genetic blueprint for your child, directly influencing their physical traits and biological characteristics.

By going way beyond the standard semen analysis, a SDF test is the only test that gives you a deeper understanding of your sperm health and whether your sperm can:

  • Reach the egg – strong enough to swim to their target
  • Fertilise the egg – healthy enough to create an embryo
  • Support a successful pregnancy – reducing the risk of miscarriage

Knowing this can give you valuable insights for your fertility journey and help guide the best next steps.
