1. Subversion cognition: The "hidden tasks" and "invisible flaws" of sperm
Traditionalwisdom holds that the mission of sperm is only to carry half of its genes and combine with an egg. However, the 2023 "China Experts Consensus on the Assessment and Management of Male Factors in Repeated Pregnancy Loss" clearly points out that sperm is far from being a passive gene carrier. It is the "chief engineer" and "navigator" of early embryonic development.
·Centriole defects in spermThis can cause the fertilized egg to stop dividing at an early stage, resulting in poor embryonic development potential.
·High sperm DNA fragmentation rateThis can directly damage the mitochondria in the embryo’s “energy factory”, causing the embryo to stop developing under seemingly ideal cultivation conditions. Alternatively, it may lead to biochemical pregnancies after implantation, resulting in fetal demise.
This means that even if the results of semen analysis (quantity, motility, morphology) are satisfactory, there may still be hidden defects that cannot be detected by conventional tests. These defects can be the real culprit behind repeated failure in IVF attempts.
Theconcept of "I am functioning normally, pregnancy is your business" is one-sided.
“,”.The assessment of male fertility has gone far beyond the functional level of "whether a woman can be pregnant" and has gone deep into the quality level of "whether a healthy life can be formed." It is common in clinical practice that the man "feels good" in everything, but the woman failed to transplant high-quality embryos many times. It was not until in-depth examination that it was discovered that the man's sperm DNA fragmentation rate (DFI) was abnormally elevated or carried certain pathogenic genes. Men's "health" status needs to be measured by the precise yardstick of modern reproductive medicine, rather than subjective feelings.
Many "killers" that damage the quality of sperm are lurking in daily life, silently affecting the fate of embryos.
Many of the “killers” that impair sperm quality lurk in everyday life, silently influencing the fate of embryos.
▶Environmental toxins – plasticizers

,,.Studies have shown that increased concentrations of plasticizer metabolites in men are significantly associated with a decrease in the live birth rate of IVF. By interfering with the "epigenetic" programming of sperm, even if an embryo is formed, it may fail due to chaotic development instructions.
▶obesity

.Studies have pointed out that men with a BMI of more than 30 have a significant decrease in sperm quality, and chronic inflammation caused by obesity reduces the key ability of sperm to adhere to the endometrium, directly affecting embryo implantation.
Faced with challenges, expectant fathers should become active "partners" rather than passive "suppliers."

,DNA(DFI).If necessary, levels of environmental toxins (such as bisphenol A, phthalate metabolites) can be detected in urine.
·Stay away from toxins: Avoid using plastic products to contain hot food and hot drinks; choose non-fragrant or light fragrant toiletries with simple ingredients.
· Stay away from toxins: Avoid using plastic containers to hold hot or hot drinks. Choose products with no or mild fragrance, and those with simple ingredients.
· Managing weight: Maintain a BMI within the healthy range (18.5-24.9) through proper diet and exercise, such as 150 minutes of moderate-intensity exercise per week.
· Optimize nutrition: Increase the intake of antioxidant-rich foods such as dark green vegetables, tomatoes, and nuts. Additionally, it’s important to supplement with nutrients like zinc, selenium, and vitamins C/E. These factors can help reduce the rate of DNA damage.
Fertility is a dance of life, not a solo of one party.
,.The emergence of test-tube technology should not be a reason to unilaterally impose fertility pressure on women. Instead, it provides a mirror for us to understand fertility responsibilities more scientifically and equally. When expectant fathers let go of their outdated self-confidence and participate in scientific evaluation and positive self-adjustment with an open attitude, it is often the beginning of breaking the dilemma and welcoming new hope. A "seed" of true health stems from the common understanding and dedication of both parties.
