The program is structured as a 10-week plan. This is because is this is the critical window for both sperm and egg health. The sperm a man's body starts to produce today, will only be ready for ejaculation in around 10-weeks time. And although a woman has all of her eggs from birth, the egg starts maturing around 3 months before ovulation. What both parents do in these months leading up to conception has a huge impact on a child's health. Not only can the egg and sperm get damaged from unhealthy food, toxins and poor lifestyle choices, but these also change the epigenetic expression of the DNA. These changes can either set a child up, or handicap their health for life.

Once you sign up, we'll send you your at-home test kits (depending on which program you select), which takes 3-5 days. All the instructions to complete the tests are included in the boxes. Return the tests to the labs using the pre-paid return label included with the kit. Once we have your results, a fertility and epigenetic expert will analyse the data and determine your targeted intervention plan. We'll notify you once this is ready, and your 10-week program will begin.

We combine all of your data (lifestyle audit + all test results, biometrics etc.) and run it through our proprietary health screening system, which is then looked over by a fertility expert and epigeneticist. We assess your results against both fertility and epigenetics markers, and look at the combined health of both partners to assess the potential risk areas.

The program is very simple, but that doesn’t make it easy. It really depends on you, what your specific interventions are, and your ability to stick with things when it gets tough.

If you’re actively trying, that’s a real possibility. Don’t worry if this happens! Any improvements to your health will improve the quality of your sperm and epigenetic health. So any improvements you make will benefit your future child.

Depending on your semen health, we may recommend you speaking with a urologist if we think medical intervention may be appropriate. However, the waiting time to see a urologist is often 6+ months so in the meantime, we’ll give you two options: 1) continue with your Upstream program to see if you can improve things naturally in the meantime, or 2) we’ll refund you for the cost of the program (minus the tests you’ve been sent). The choice is yours.

Your epigenetics affect how your genes are expressed and can influence your child’s health and development. Lifestyle factors like your diet, stress levels, sleep quality, and exposure to toxins can modify how certain genes function, and these changes can be passed on to your child. This means your habits before conception can shape your child’s baseline health, impacting their growth, resilience, and risk for conditions later in life.

Yes, definitely. If you're going to be freeze and store your sperm, you should make sure it's the best quality sperm possible. The quality of your sperm when frozen, will impact how effective it is at fertilizing an egg in future. The other thing to consider is the epigenetic health of your sperm. Freezing sperm acts like a time capsule. Your health today will be preserved and (possibly) be passed on to your future children. Make sure you're preserving the best version of yourself possible.

The importance of preconception health is a relatively new focus for many, but the science has actually been around for years. Research in epigenetics has long shown how preconception habits profoundly shape a child’s long-term health. However, the medical field often takes time to catch up with cutting-edge science, and many doctors still focus primarily on maternal health during pregnancy rather than the critical period before conception. As awareness grows, this gap is slowly closing, but the message hasn’t reached everyone yet.
