A test that evaluates the integrity of sperm DNA to support fertility planning and treatment.
Helpful tools

What is Sperm DNA Fragmentation Testing?

At Sunfert, we define Sperm DNA Fragmentation Testing as a specialised assessment that measures the amount of damaged DNA in a man’s sperm. Healthy DNA in sperm is essential for fertilisation, embryo development, and a successful pregnancy.

High levels of DNA fragmentation can contribute to difficulties in conceiving, recurrent miscarriages, or unsuccessful IVF attempts.

By identifying DNA damage early, our testing allows us to tailor fertility treatments effectively, enhancing your chances of achieving parenthood.

Who Can Benefit from Sperm DNA Fragmentation Testing?

We recommend this test for men who experience:

  • unexplained infertility despite regular attempts to conceive
  • repeated IVF or IUI failures
  • recurrent miscarriages
  • lifestyle factors that may affect sperm quality, such as smoking, excessive alcohol consumption, or prolonged stress
  • advanced paternal age, which can increase DNA damage in sperm

By understanding the condition of sperm DNA, we can guide couples towards the most suitable treatment strategy, whether it involves lifestyle modifications, medical therapy, or assisted reproductive techniques.

When Should You Consider Sperm DNA Fragmentation Testing?

We suggest considering testing if you notice:

  • difficulty conceiving after 6–12 months of trying
  • previous unsuccessful assisted reproduction attempts
  • known risk factors like varicocele, exposure to toxins, or chronic illness
  • concerns about paternal age or lifestyle influences on fertility

Early testing helps us pinpoint potential challenges and create a personalised approach to improve fertility outcomes.

If you are concerned at any stage – we recommend booking a doctor appointment or a free nurse consultation. The sooner you make a plan the better your chances in the long term.

When to seek advice early
  • If you have polycystic ovaries, endometriosis, or have been through a cancer diagnosis; we recommend you get in touch quickly so we can talk you through all your options and give you the greatest possible chance of success.
  • If you’re a single woman considering motherhood in the future; it’s best to approach us early and consider egg freezing as this can be an option for you while you have a higher ovarian reserve and healthier eggs.

Body Mass Index calculator

Being overweight or underweight can reduce fertility, so it is important to keep your body weight within the normal healthy range.

Body Mass Index (BMI) is an indication of your body weight and can be calculated by dividing weight by height. You should aim for a BMI of between 20 and 25, as this will optimise your chances of conception.

Woman’s BMI below 19

Even in these modern times, nature knows best. If a woman's BMI falls below 19, the body senses famine and ovulation is switched off to prevent the risk of having a baby with malnutrition. Excessive exercise can reduce body fat and increase muscle mass to a point where periods cease for the same reason. Risk of miscarriage is also increased in women with a low BMI.

Being underweight

If a woman's BMI falls below 19, the body senses famine and ovulation is switched off to prevent the risk of having a baby with malnutrition. Excessive exercise can reduce body fat and increase muscle mass to a point where periods cease for the same reason. Risk of miscarriage is also increased in women with a low BMI.

BMI’s greater than 30

This can reduce fertility by 50%. Pregnancy for women with a 30+ BMI is often associated with problems such as maternal diabetes, high blood pressure, big babies and increased risk of caesarean section.
