Ceres Fertility Recommends Fertility Phix and they have kindly given us a discount code for all who visit them, JUSTINE is the code. When couples are trying to conceive naturally or through fertility treatment such as IVF or ICSI, the focus is often placed on egg quality and the female partner. However, male fertility contributes to 50% of embryo quality, and one of the most important factors in male fertility is s***m DNA fragmentation.
S***m DNA fragmentation refers to damage to the genetic material inside the s***m. Even when s***m count, motility and morphology appear normal, high DNA fragmentation can still lead to:
Poor embryo development
Low fertilisation rates
Poor blastocyst development
Failed IVF cycles
Implantation failure
Miscarriage
The good news is that s***m DNA fragmentation can often be improved in approximately 90 days, which is the time it takes for new s***m to be produced.
What Causes High DNA Fragmentation in Men?
The most common cause of s***m DNA damage is oxidative stress, which damages s***m during production and storage. Many lifestyle and environmental factors increase oxidative stress and s***m DNA damage.
Heat Exposure – Saunas, Steam Rooms, Hot Baths
S***m are produced outside the body because they require a cooler temperature than body temperature. Heat exposure increases scrotal temperature and can significantly increase DNA fragmentation.
Men trying to improve s***m DNA should avoid:
Saunas
Steam rooms
Hot baths
Heated car seats
Laptops placed on the lap
Long hot showers
Keeping the testicles cool is extremely important for s***m production and DNA quality.
Tight Underwear and Tight Clothing
Tight underwear and tight trousers increase scrotal temperature and reduce s***m quality over time. Men trying to conceive should wear:
Loose boxer shorts
Loose trousers
Breathable fabrics
Smoking, Alcohol and Recreational Drugs
Smoking is one of the biggest causes of s***m DNA damage. Alcohol and recreational drugs increase oxidative stress and reduce s***m quality.
Men trying to improve fertility should:
Stop smoking
Avoid va**ng
Limit alcohol
Avoid recreational drugs
Illness, Flu, Viruses and Fever
Many men do not realise that a fever, flu, COVID, or viral illness can damage s***m DNA for up to 3 months.
S***m production takes approximately 72–90 days, so any illness in the last 3 months can affect s***m quality and embryo development.
If a man has had:
Flu
Fever
COVID
Viral infection
Infection requiring antibiotics
It is often recommended to wait 3 months before fertility treatment so new healthy s***m can be produced.
Steroids and Testosterone Use
Anabolic steroids and testosterone supplements can shut down natural s***m production and severely damage s***m DNA and fertility.
Men should avoid:
Bodybuilding steroids
Testosterone injections
Testosterone gels
Performance enhancing drugs
These can cause very high DNA fragmentation and very low s***m counts.
Long Abstinence Periods
Long periods without ej*******on can increase s***m DNA damage because s***m deteriorate while stored in the body. Many fertility specialists recommend ej*******ng every 2–3 days to improve s***m DNA quality.
How Men Can Reduce DNA Fragmentation
The good news is that DNA fragmentation can often be reduced with lifestyle changes, antioxidants and supplements.
Men should aim to make changes for at least 90 days before IVF, ICSI or trying to conceive.
Lifestyle Changes to Improve S***m DNA
Diet
Eat a diet rich in antioxidants:
Fruits
Vegetables
Nuts
Fish
Olive oil
Whole grains
Berries
Leafy greens
Antioxidants help reduce oxidative stress and protect s***m DNA.
Exercise
Moderate exercise improves testosterone levels, s***m production and overall fertility. Avoid excessive cycling or overheating during exercise.
Sleep
Poor sleep negatively affects testosterone and s***m production. Aim for 7–8 hours of sleep per night.
Weight
Being overweight or obese is linked to increased DNA fragmentation and poor s***m quality.
Stress
Chronic stress increases oxidative stress and hormone imbalance, which can damage s***m DNA.
Avoid Toxins
Men should try to reduce exposure to:
Pesticides
Chemicals
Plastics
Heavy metals
Pollution where possible
Supplements to Improve S***m DNA
Oxidative stress is one of the main causes of s***m DNA damage, and antioxidant supplements can help improve s***m DNA quality.
Common supplements for male fertility include:
CoQ10
Zinc
Selenium
Vitamin C
Vitamin E
Omega-3
L-Carnitine
Folic Acid
Lycopene
Ceres Fertility recommend Fertility Phix male fertility supplements to support s***m health, improve DNA quality and support embryo development. Fertility Phix have many more beneficial vitamins included in their supplements and have proven success in this field.
Supplements should ideally be taken for at least 3 months before IVF or embryo creation.
90 Day Male Fertility Improvement Plan
Men trying to improve s***m DNA and fertility should follow this plan for 90 days:
Stop Immediately
Smoking
Steroids/testosterone
Saunas and steam rooms
Hot baths
Tight underwear
Heavy alcohol
Recreational drugs
Laptops on lap
Start Immediately
Fertility supplements
Antioxidant rich diet
Exercise
Good sleep
Drink plenty of water
Reduce stress
Wear loose underwear
Keep testicles cool
Ej*****te every 2–3 days
Final Thoughts
Male fertility plays a major role in embryo quality, IVF success and miscarriage risk. High s***m DNA fragmentation is often a hidden cause of poor embryo development and failed fertility treatment.
The positive news is that s***m DNA fragmentation can often be significantly improved in just 90 days with the right lifestyle changes, supplements and medical guidance.
Improving s***m DNA quality before IVF or embryo creation can significantly improve embryo quality, implantation rates and overall fertility outcomes.
