Your sperm DNA is your baby’s blueprint

DNA is what makes us who we are. Your sperm DNA carries a copy of the genes that you pass on to your baby. Not only do your genes pass on your characteristics, like eye colour or height, but they build our brains, determine our behaviour and our future health.

Sperm DNA can be damaged when sperm are made, breaking the DNA into smaller fragments. Men with high levels of damaged sperm DNA are less likely to get their partner pregnant and have double the risk of miscarriage. Even if your sperm count is normal, the sperm may not be of good quality, and therefore sperm DNA damage can prevent you from having a baby.

Why get tested?

The Exact Fertility® test measures sperm DNA damage. Knowing whether you have sperm DNA damage can help you make informed decisions about medical treatments or lifestyle changes to improve your sperm DNA and fertility. Exact Fertility® is the only professional-grade sperm DNA test available without a doctor’s referral.

Facing infertility can feel like a long, confusing road. Having a clear understanding of your fertility, right at the start of your journey, will enable you to make an informed decision on which direction is right for you and your partner.

Exact IVF & ICSI Explained

The Exact IVF® and Exact ICSI® professional tests provide detailed information that enables healthcare professionals to identify which fertility treatment is right for you. ICSI is a more successful treatment than IVF if a man has very high levels of damaged sperm DNA. ICSI is most successful when sperm with lower levels of DNA damage are used. Improving your sperm DNA through medical intervention or lifestyle changes before treatment can improve your chance of success.

Understanding the extent of sperm DNA damage before you embark on fertility treatment, can help predict the likelihood of treatment success saving you the time, cost and emotional toll of repeated fertility treatment.
