In the diagnosis and treatment of infertility, male sperm problems often put families in trouble, especially the result of "high sperm DNA fragmentation rate (DFI)", which makes many men call out "the sky is falling":"Does a high fragmentation rate mean sterilization? Even the genetic material in the sperm is broken, so it's impossible to make a test tube, right?" Today, we use a brand new real diagnosis and treatment case to help everyone clear the fog: high DFI has never been a "dead end" for childbirth, blindly following the trend and eating health products is the real detour, and the third generation of IVF technology is the key to breaking through the dilemma.
1. Popular explanation: What exactly is Sperm DNA Fragmentation Rate (DFI)?
,DNA(DFI)“”.We can compare sperm to a express package carrying a "genetic file package". DFI tests whether the file package is damaged and whether the documents (DNA) inside are complete. When the DNA chain is broken or incomplete,"fragments" are formed. The higher the DFI value, the higher the proportion of sperm representing a "broken file" in semen.
,,DNA,.Many people will naturally associate it with: Does high DFI mean poor embryo quality? Is it easier to get pregnant and lose? Is the test tube sure to fail? This kind of worry is understandable, but in clinical practice, directly equating high DFI with "hopeless childbearing" is actually a huge cognitive bias.
40-year-old Mr. Wang and his wife had failed to plan for a pregnancy for three years, during which they experienced an early abortion, which made the couple's journey to seek a child particularly difficult.
403,,.Their diagnosis and treatment experience hides the common confusion of many patients with high DFI.
1. Crucial inspection results
Aftera comprehensive examination by the couple, all indicators of his wife were normal, and the problem lay with Mr. Wang. The semen analysis report showed that not only was his sperm forward mobility only 21%(the normal reference value was 32%), which was a asthenospermia, but more importantly, his DFI value was as high as 35%(usually a DFI of 30% means a high fragmentation rate). The moment he received the report, Mr. Wang bluntly said: "My fertility has declined at this age. Now my sperm is still weak and 'broken'. I definitely can't give my wife a healthy baby."
2. 6 months of "ineffective consumption of health products"
After the early abortion, a friend told Mr. Wang that "eating antioxidant health supplements can repair sperm DNA." He believed it without consulting a professional doctor. From imported coenzyme Q10 and zinc and selenium tablets to the "conditioning folk prescriptions" circulated among the people, he bought more than a dozen kinds and persisted in eating them for 6 months. Not only did he spend nearly 20,000 yuan in savings, but the DFI value during the review. Instead, it rose to 37%. What worried him even more was that long-term random tonic caused him to develop symptoms of fatigue and loss of appetite. Examination found mild abnormalities in liver function indicators. The desperate couple finally came to our reproductive center for help.
After carefully sorting out Mr. Wang's medical history, examination report and previous conditioning, the expert team gave the core diagnosis and treatment ideas: immediately stop blind tonic, and overcome the difficulties of childbirth through a combination of "scientific life conditioning + precise test tube technology".
The expert team carefully reviewed Mr. Wang’s medical history, examination results, and previous treatment efforts. They concluded that the most effective approach is to immediately stop any unnecessary dietary supplements. Instead, a combination of “scientific lifestyle adjustments” and “precision reproductive technology” should be used to overcome the challenges related to fertility.
1. Decisively stop "blind supplements"
Experts clearly informed Mr. Wang that all health care products and folk prescriptions that had not been evaluated by doctors had been discontinued. Experts explained that there is currently no evidence-based medical evidence to show that conventional health products can effectively reduce high DFI. On the contrary, messy supplements will increase the metabolic burden of liver and kidney, even interfere with the endocrine balance in the body, and indirectly affect the spermatogenic function. This is also the important reason why his DFI value rises instead of falling.
2. Personalized "Life Conditioning Guide"
Combined with Mr. Wang's 40-year-old age and his irregular work schedule and long-term sedentary work characteristics, experts formulated a four-month personalized life conditioning plan for him.
•Adjust your workand rest strictly to avoid staying up late, fall asleep before 10:30 every night, and ensure more than 7 hours of sleep every day, because night is a critical period for the repair and production of spermatogenic cells.
•Diet and TaboosCompletely quit smoking and alcohol, refuse coffee, strong tea and high-sugar drinks, eat more deep-sea fish, nuts, spinach and other foods rich in unsaturated fatty acids and trace elements, while controlling weight, and avoiding obesity affecting hormone levels
•Exercise and decompressionCarry out aerobic exercise 4 times a week, 40 minutes each time, and choose mild exercises such as brisk walking, jogging, and swimming; at the same time, he is advised to take a 30-minute walk every day, combined with deep breathing relaxation training, to relieve the dual pressure of preparing for pregnancy and work.
3. "ICSI+PGT" precision test tube technology solution
In response to Mr. Wang's high DFI+ asthenospermia, experts formulated a precise treatment strategy of "ICSI (second-generation test tube)+PGT (third-generation test tube)" for the couple
·Step 1: Precise fertilization with ICSI technology

Due to Mr. Wang's poor sperm vitality, natural fertilization is difficult and the DFI is high. Embryologists will use a high-powered microscope., accurately select a single sperm with normal shape and suitable vitality from the semen and inject it directly into the egg to complete fertilization. This step is equivalent to "selecting semen from the best" and avoids the macro impact of poor overall semen quality and high DFI
·Step 2: PGT technology embryo screening

Thecore risk of high DFI is that it may lead to chromosomal abnormalities in the embryo, which may lead to miscarriage. Therefore, experts will conduct PGT gene screening on the cultured blastocysts to accurately determine whether the chromosomes of each embryo are normal, and only select healthy embryos for transplantation to block paternal genetic risks from the root cause and ensure pregnancy success rate and fetal health.
Four months later, Mr. Wang and his wife returned to the center to start the test tube cycle.
4,.The reexamination results showed that his sperm forward mobility increased to 28%, and the DFI value dropped to 31%. Although it still had a high fragmentation rate, the overall condition had improved significantly and the mental stress had been much less. The treatment process went smoothly
·Thewoman successfully removed 11 mature eggs
·FertilizationThrough ICSI technology, 10 eggs were successfully fertilized, with a fertilization rate of 91%
·Nurturing and screeningfinally produced 6 high-quality blastocysts. After PGT screening, 2 embryos had completely normal chromosomes
·Transplantation and OutcomeThe doctor transplanted a high-quality normal embryo for them. 14 days after transplantation, blood tests confirmed a successful pregnancy; 30 days after transplantation, B-ultrasound showed that the gestational sac was normal and the fetal heart was beating strongly. The couple have now successfully entered the mid-trimester prenatal check-up stage.
5. Core logic: Why can high DFI still lead to successful results through third-generation IVF?
•

PGT technology solves the "potential risks" The most terrifying thing about high DFI is not the difficulty of fertilization, but the possible chromosomal abnormalities in the embryo after fertilization.
▶PGT technology addresses these “potential risks”.

DFI,.PGT technology is like an "embryo quality inspection instrument" that screens out abnormal embryos before transplantation. As long as the transplanted embryos are healthy, the pregnancy success rate is almost no different from that of normal embryos.
•Scientific conditioning improves the "basic conditions"

Althoughhealth care products are ineffective, targeted life conditioning can improve the spermatogenic environment and improve the overall vitality and quality of sperm, laying a good foundation for the smooth implementation of test tube technology.
,DFI,,“”.For patients with high DFI, the effective path is to hand over professional diagnosis and treatment to reproductive experts, and implement daily life conditioning-regular work and rest, healthy eating, moderate exercise, coupled with the precise support of three generations of test-tube technology, you can overcome fertility barriers. Childbirth has never been a matter for one person, nor is it something that can be solved by "folk prescriptions". Believe in science and find the right method, good pregnancy will naturally come as scheduled.
