Fertility · Reproductive Hormones · Fertility Genes
This report reads your DNA and sorts every result into one of five plain-language groups, so you can see at a glance what deserves attention and what does not. Nothing here is a diagnosis. A flagged result means your genetics place you above or below the average person for that trait — a reason to ask a question, not a reason to worry.
Fertility — Male reproductive health is influenced by a combination of genetic, hormonal, and environmental factors. Genetics plays a significant role in determining fertility and the balance of reproductive hormones, both of which are crucial for reproductive function.
These are ordered by how closely they relate to your flagged results — not generic health advice. Marrow does not prescribe, dose, or tell you to take anything. Diet and lifestyle changes are listed first because they are yours to make. Anything you would swallow is listed separately, by name only, as something to raise with a clinician who knows your history and your medications.
Limit the use of non-organic lawn and garden chemicals.
Refrain from using products containing organic solvents such as paints, varnishes, paint strippers, cleaning supplies, glues, and adhesives.
Use exhaust fans in kitchens and ensure proper ventilation when cooking at high temperatures to reduce indoor levels of PAHs.
Ensure you allocate enough time in your schedule to achieve a minimum of 7 hours of sleep each night.
Limit red meat to a few times a month and include a moderate amount of dairy products.
Aim for at least one serving (approximately 1 medium-sized tomato or 1/2 cup of chopped or cooked tomatoes) per day.
Do not use opioid medications unless prescribed by a healthcare provider for specific medical conditions where pain management is necessary, and even then, use them only as directed for the shortest possible duration.
Do this consistently as part of your daily dietary intake.
These came up in the research behind your flagged results. They are listed by name so you can ask about them. Marrow is not recommending them, and gives no dose. Supplements interact with prescription medication and with each other — that conversation belongs with your clinician.
Of the 14 results in this package, these 1 came back furthest from the population average. Each one below explains what it is, where you sit, and which report it came from. Start here.
Key Takeaways: Genes affecting male fertility may be involved with sperm production and protecting DNA from damage.
Risk factors include: certain health or anatomical issues, stress, medical treatments, chemical/heat exposure, drug and alcohol use, smoking, obesity.
If you have a high genetic risk, you may reduce overall risk by taking action on risk factors that you can change.
Named only. Marrow gives no dose and does not recommend these.
Not everything in a genetic report is a warning. These came back protective or better than average.
Several factors can increase the risk of developing testicular cancer: Undescended testicle at birth Family history Personal history Age: Most common in men between 15 and 35.
Ethnicity: More common in Caucasian men compared to African-American men.
Treatment options depend on the cancer’s stage and type and may include: Surgery: The primary treatment is often a radical inguinal orchiectomy, where the affected testicle is removed through an incision in the groin.
The remaining results, grouped by what they mean. Every one of these is explained in full — with the genes and variants behind it — in the technical version of this report.
Genetics is a predisposition, not a verdict. The single most useful thing you can do with this document is take it to a clinician and talk through the flagged findings — especially any that line up with symptoms you already have or conditions that run in your family. Nothing here changes: your DNA is the same at 60 as it is today, so this report does not expire.
Genotyping was performed on DNA extracted from a buccal (cheek) swab using a genome-wide array. Results are derived from peer-reviewed genome-wide association data and, where applicable, published clinical guidelines. Each report was scored independently against its own reference set. Percentile figures describe where your result sits relative to a reference population.
This is a laboratory-developed test. It has not been cleared or approved by the U.S. Food and Drug Administration. Genotyping does not detect all variants in the genes assessed; the absence of a flagged result does not exclude risk. Predisposition is probabilistic and is modified by environment, lifestyle, ancestry and family history. Results must be interpreted by a qualified healthcare professional and must not be used alone to diagnose, treat, or alter any medication regimen. Marrow does not recommend, prescribe, or dose any supplement or medication.
