However, some sperm may not be able to repair DNA, and a man may face difficulty conceiving if the DNA fragmentation percentage increases.   <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is a sperm DNA fragmentation test?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A sperm DNA fragmentation test <em>&#8220;DNA Fragmentation test&#8221;<\/em> aims to measure the percentage of DNA fragmentation in a semen sample by examining the sperm head specifically.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Sperm DNA fragmentation rate<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The normal sperm DNA fragmentation rate is 15%, and it may reach 30% without a major impact on reproductive ability. However, if the sperm DNA fragmentation rate exceeds 30%, the chances of pregnancy occurring or continuing decrease.  <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The following table shows the relationship between sperm DNA fragmentation and a man\u2019s ability to conceive:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>DNA fragmentation rate<\/strong><\/td><td><strong>Chances of conception<\/strong><\/td><\/tr><tr><td>Less than 15%<\/td><td>Normal<\/td><\/tr><tr><td>From 15 to 30%<\/td><td>Moderate<\/td><\/tr><tr><td>More than 30%<\/td><td>Low<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">How to read a DNA Fragmentation test<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The test includes the DNA fragmentation rate &#8220;%SDF&#8221;, which indicates the percentage of DNA fragmentation in the sperm head. The result is considered normal if it is less than 15%, while fertility is slightly affected if the result is 15\u201330%. An increase above 30% is associated with low chances of conception.    <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">When do you need a sperm DNA fragmentation test?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">An andrologist may request a sperm DNA fragmentation test in the following cases:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Unexplained delayed conception.<\/li>\n\n\n\n<li>Recurrent miscarriage without a clear cause.<\/li>\n\n\n\n<li>Before using assisted reproductive techniques, such as ICSI. <\/li>\n\n\n\n<li>Repeated ICSI failure and embryos not reaching day 5.<\/li>\n\n\n\n<li>When factors that negatively affect fertility are present, such as varicocele, obesity, and smoking.   <\/li>\n\n\n\n<li>Sperm freezing.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Requirements for a sperm DNA fragmentation test<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The test requires a semen sample. Below are the requirements for collecting the sample: <\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Abstain from intercourse or ejaculation for 2\u20135 days in most cases.<\/li>\n\n\n\n<li>Keep the semen sample at room temperature.<\/li>\n\n\n\n<li>Submit the sample to the lab within 30\u201360 minutes at most.<\/li>\n\n\n\n<li>Be in good health when taking the test.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">How is a sperm DNA fragmentation test performed?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">There is more than one technique to measure the percentage of DNA fragmentation in a semen sample, such as: <\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Sperm Chromatin Structure Assay (SCSA).<\/li>\n\n\n\n<li>Sperm Chromatin Dispersion test (SCD).<\/li>\n\n\n\n<li>Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) test.<\/li>\n\n\n\n<li>Single-cell gel electrophoresis (COMET) test.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">How long does a sperm DNA fragmentation test take?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The duration of the sperm DNA fragmentation test varies by lab and test type. Typically, the result appears within a few days after submitting the semen sample.  <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Causes of sperm DNA fragmentation<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">There are several reasons behind increased sperm DNA fragmentation, such as: <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Increased reactive oxygen species (ROS)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Increased reactive oxygen species lead to <strong>oxidative stress<\/strong>, which causes many types of damage to the body\u2019s cells, including sperm.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Reactive oxygen species increase the man\u2019s DNA fragmentation rate, in addition to increasing the rate of <a href=\"https:\/\/dr-mwael.com\/en\/sperm-abnormalities-pregnancy-with-a-100-abnormality-rate\/\">sperm abnormalities<\/a>, which affects his ability to conceive.  <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Natural antioxidants protect the body from this damage, so the DNA fragmentation rate increases when antioxidants are deficient. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Varicocele<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Varicocele affects about 15% of men and is one of the most prominent causes of reduced sperm quality. According to some recent studies, men with varicocele are more prone to DNA fragmentation in the sperm head, and varicocele also increases reactive oxygen species.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Infection<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Medical reports indicate that some types of bacterial infections in the urinary or reproductive tract increase sperm DNA fragmentation, such as <em>&#8220;Chlamydia&#8221;<\/em> and <em>&#8220;Mycoplasma&#8221;<\/em> infections. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Testicular temperature<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The testicles have a relatively lower temperature than the body to ensure the highest-quality sperm production. However, when testicular temperature rises, sperm quality decreases and DNA fragmentation increases.    <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, it is recommended to avoid placing a laptop directly on the thighs and to avoid tight clothing to prevent increased testicular temperature. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Weight gain<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Obesity causes many health problems and is also one of the causes of sperm DNA fragmentation, as weight gain leads to:  <\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Increased reactive oxygen species.<\/li>\n\n\n\n<li>Increased testicular temperature.<\/li>\n\n\n\n<li>Poor sperm quality.<\/li>\n\n\n\n<li>Increased DNA fragmentation in men.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">6. Reproductive tract inflammation<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Reproductive tract inflammation, such as epididymitis or prostatitis, affects semen and sperm quality. Inflammation also increases reactive oxygen species, thereby increasing the semen fragmentation rate in men.    <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">7. Smoking<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Smoking is one of the causes of poor sperm quality, and long-term smoking may lead to: <\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Reduced fertility.<\/li>\n\n\n\n<li>Increased sperm DNA fragmentation.<\/li>\n\n\n\n<li>Sperm abnormalities.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Frequent exposure to cigarette smoke may also cause the same damage as smoking, even if you are not a smoker. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">8. Chemotherapy and radiotherapy<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Treating some cancers requires radiotherapy sessions or chemotherapy. However, these treatments may affect testicular function and male fertility in several ways, including increasing the sperm DNA fragmentation rate.  <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Symptoms of increased sperm DNA fragmentation<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In fact, there are no specific symptoms of increased sperm DNA fragmentation except <strong>delayed conception<\/strong>. Your doctor may recommend a sperm DNA fragmentation test in the following cases:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Recurrent early miscarriage.<\/li>\n\n\n\n<li>Delayed conception for no clear reason.<\/li>\n\n\n\n<li>Previous repeated ICSI failure.<\/li>\n\n\n\n<li>ICSI embryos not reaching day 5.<\/li>\n\n\n\n<li>Delayed conception with factors affecting testicular health, such as: \n<ul class=\"wp-block-list\">\n<li>Obesity. <\/li>\n\n\n\n<li>Smoking. <\/li>\n\n\n\n<li>Varicocele.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Treatment of sperm DNA fragmentation in men<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Treatment of sperm DNA fragmentation depends on preventing negative factors that affect testicular function, which helps improve sperm quality and reduce DNA fragmentation. Therefore, treatment may include the following:   <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Taking antioxidants<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Antioxidants are an effective treatment for sperm DNA fragmentation caused by oxidative stress <em>&#8220;Oxidative stress&#8221;<\/em>, which occurs when reactive oxygen species increase. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Several studies have reported that taking antioxidants protects sperm from DNA fragmentation. Your doctor may recommend supplements such as: <\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Vitamin C.<\/li>\n\n\n\n<li>Vitamin E.<\/li>\n\n\n\n<li>Zinc.<\/li>\n\n\n\n<li>Selenium.<\/li>\n\n\n\n<li>N-acetylcysteine.<\/li>\n\n\n\n<li>Coenzyme Q10.<\/li>\n\n\n\n<li>L-carnitine.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">2. Improving lifestyle<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Sperm DNA fragmentation may increase due to unhealthy habits. The following tips can help reduce sperm DNA fragmentation: <\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Losing excess weight.<\/li>\n\n\n\n<li>Maintain a healthy diet rich in antioxidants. <\/li>\n\n\n\n<li>Avoid placing a laptop directly on the thighs.<\/li>\n\n\n\n<li>Quit smoking and avoid exposure to cigarette smoke. <\/li>\n\n\n\n<li>Maintain good personal hygiene to reduce the risk of infection.<\/li>\n\n\n\n<li>Avoid exposure to radiation and harmful chemicals.<\/li>\n\n\n\n<li>Wear loose, comfortable clothing to maintain testicular temperature.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">3. Treating varicocele<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Treating varicocele helps reduce the sperm DNA fragmentation rate, as testicular function improves and sperm quality increases. Therefore, your doctor may recommend microsurgical varicocelectomy to improve sperm quality and enhance fertility.   <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Treating chronic inflammation<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">You should consult a doctor if there is inflammation or infection in the urinary or reproductive tract. Chronic inflammation may affect sperm quality and increase sperm DNA fragmentation. Symptoms of inflammation or infection may include:   <\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Pelvic pain.<\/li>\n\n\n\n<li>Pain or burning during urination.<\/li>\n\n\n\n<li>Frequent urge to urinate.<\/li>\n\n\n\n<li>Changes in urine smell or color.<\/li>\n\n\n\n<li>Pain and swelling in the scrotum.<\/li>\n\n\n\n<li>Unusual discharge from the urethral opening.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The doctor may request some tests to diagnose the cause of inflammation and determine the most appropriate treatment protocol. Treating inflammation helps improve sperm quality. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Can pregnancy occur with sperm DNA fragmentation?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, pregnancy may occur naturally as long as the sperm DNA fragmentation rate is less than 30%. However, if it exceeds that, the chances of natural pregnancy decrease, and the likelihood of early miscarriage increases. Therefore, the doctor will determine a comprehensive treatment plan to reduce DNA fragmentation and increase the chances of conception.     <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Advanced techniques such as ICSI can help achieve the dream of having children if the sperm DNA fragmentation rate does not improve, especially when ICSI is supported by modern techniques to select healthy sperm, such as MACS. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">ICSI<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">ICSI <em>&#8220;ICSI&#8221;<\/em> is a modern technique for treating male infertility. It is a precise medical procedure in which sperm is manually injected into the egg to form an embryo outside the uterus, repeated to form a number of embryos. Doctors then monitor embryo development to select high-quality embryos for transfer to the uterus.   <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">MACS technique<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">MACS <em>&#8220;Magnetic-Activated Cell Sorting&#8221;<\/em> improves sperm quality for ICSI by using electromagnetic separation to exclude sperm with high DNA fragmentation. This allows the doctor to use only healthy sperm in ICSI, enhancing the chances of success.  <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">ICSI with MACS helps achieve the dream of having children if the man\u2019s DNA fragmentation rate does not improve, or when there is not enough time to treat sperm DNA fragmentation due to low ovarian reserve in the wife. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Herbal treatment for sperm DNA fragmentation<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Some herbs rich in antioxidants can reduce oxidative stress. Preliminary studies indicate that some herbs may help reduce sperm DNA fragmentation, <strong>but as a complementary treatment, it does not replace approved medical protocols<\/strong>. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A 2024 medical study indicated the effectiveness of velvet bean, ashwagandha, and Malaysian ginseng in herbal treatment for sperm DNA fragmentation and enhancing male fertility. However, you should consult your doctor before taking any herbs to assess their effectiveness, safety, and potential side effects.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">My experience with DNA fragmentation<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;I was facing repeated ICSI failure over 5 years. The problem was my husband\u2019s high DNA fragmentation, and conventional techniques did not help us conceive. Then we found a specialized center that uses modern ICSI techniques to select healthy sperm. Indeed, ICSI succeeded from the first attempt, and the pregnancy test came back positive!&#8221;    <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Treatment of sperm DNA fragmentation with Dr. Mohamed Wael Ragab <\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/dr-mwael.com\/en\/about-dr-mohamed-wael-ragab-consultant-in-andrology-and-infertility\/\">Dr. Mohamed Wael Ragab<\/a> is one of the experts in andrology and male infertility in Egypt and the Middle East. He is distinguished by extensive experience in dealing with sperm DNA fragmentation cases, relying on the latest diagnostic and therapeutic techniques to enhance the chances of conception. He also holds:   <\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A fellowship from the University of M\u00fcnster, Germany.<\/li>\n\n\n\n<li>Membership in the European Academy of Andrology.<\/li>\n\n\n\n<li>A fellowship of the European Society for Sexual Medicine.<\/li>\n\n\n\n<li>Consultant degree in microsurgical procedures for male infertility treatment.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Dr. Mohamed Wael Ragab\u2019s clinics provide the latest sperm selection techniques such as <strong>MACS<\/strong> <strong>and Zymot<\/strong>, which increase ICSI success rates.<strong> Do not hesitate to <\/strong><a href=\"https:\/\/dr-mwael.com\/en\/contact\/\"><strong>contact us now<\/strong><\/a><strong> to book a medical consultation and start your journey toward achieving the dream of having children!<\/strong> <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently asked questions about sperm DNA fragmentation<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In conclusion, we answer the most important frequently asked questions about male DNA fragmentation: <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does DNA fragmentation prevent pregnancy?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The chances of pregnancy decrease significantly when DNA fragmentation exceeds 30%. Nevertheless, modern techniques such as ICSI with MACS help achieve the dream of having children, and this method is highly effective in overcoming difficult cases of male infertility.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How long does DNA fragmentation treatment take?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Treatment duration varies from one case to another depending on the sperm DNA fragmentation rate and the reasons for its increase. Your doctor may advise a semen analysis after 3 months to assess improvement in sperm quality and DNA fragmentation rate, as the sperm production cycle usually takes 72 to 90 days.    <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does ICSI succeed with sperm DNA fragmentation?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, modern techniques such as MACS contribute to increasing ICSI success rates in cases of sperm DNA fragmentation. It separates healthy sperm and excludes sperm with a high fragmentation rate, allowing ICSI to produce higher-quality embryos and increasing the chances of pregnancy.    <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">DNA fragmentation rate 26: can pregnancy occur?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, pregnancy may occur naturally with a DNA fragmentation rate of 26. However, there is a moderate likelihood of delayed conception or early miscarriage. Therefore, it is recommended to consult a doctor to reduce the sperm DNA fragmentation rate to the normal level (less than 15), which improves the chances of conception.    <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is genetic testing for men?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Genetic testing for men <em>&#8220;Genetic Testing&#8221;<\/em> differs from a sperm DNA fragmentation test. It is used to diagnose any chromosomal abnormality in men that may affect their ability to conceive, such as Klinefelter syndrome or Y chromosome microdeletion.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Sources<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\" id=\"h-\"><a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S2667142524001040\">Effectiveness of Herbal medicines on male reproductive system | Science Direct<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC7763893\/\">MACS &amp; High Levels of SDF | PMC<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.topdoctors.co.uk\/medical-dictionary\/sperm-dna-fragmentation#:~:text=What%20are%20the%20symptoms%20of,your%20partner%20has%20recurrent%20miscarriages.\">Sperm dna fragmentation | Top Doctors<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/bacandrology.biomedcentral.com\/articles\/10.1186\/s12610-023-00197-9#Sec13\">Antioxidants role in reducing SDF | BMC<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.nature.com\/articles\/s41598-023-45091-6\">SDF index affect ARTs | Scientific Reports<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC3509564\/\">DNA Fragmentation in Sperm Cells | PMC<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.fertilityfamily.co.uk\/blog\/sperm-dna-fragmentation-causes-treatment\/\">Sperm DNA fragmentation | Fertility Family<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC6125150\/\">Men with sperm DNA fragmentation | PMC<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC8039607\/\">Genetic testing for men with infertility | PMC<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC7763893\/#sec5-jcm-09-03976\">Magnetic-Activated Cell Sorting (MACS) | PMC<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/progyny.com\/education\/how-to-test-for-sperm-dna-fragmentation\/\">How to Test for Sperm DNA Fragmentation? | Progyny <\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC8761233\/\">SDF: A Critical Assessment of Clinical Practice Guidelines | PMC <\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.frontiersin.org\/journals\/endocrinology\/articles\/10.3389\/fendo.2024.1418936\/pdf\">The effect of Chinese herbal medicine on male factor infertility| Frontiers<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Sperm DNA fragmentation is one of the hidden causes of male infertility.

Sperm DNA fragmentation &#8220;Sperm DNA Fragmentation&#8221; is an abnormal change in DNA that includes breakage of the bonds between the two strands, or separation of parts of the strands, causing DNA to lose its normal shape and structure. Usually, cells can repair some DNA damage to preserve genetic material without any defect. However, some sperm may not be able to repair DNA, and a man may face difficulty conceiving if the DNA fragmentation percentage increases. What is a sperm DNA fragmentation test? A sperm DNA fragmentation test &#8220;DNA Fragmentation test&#8221; aims to measure the percentage of DNA fragmentation in a semen sample by examining the sperm head specifically. Sperm DNA fragmentation rate The normal sperm DNA fragmentation rate is 15%, and it may reach 30% without a major impact on reproductive ability. However, if the sperm DNA fragmentation rate exceeds 30%, the chances of pregnancy occurring or continuing decrease. The following table shows the relationship between sperm DNA fragmentation and a man\u2019s ability to conceive: DNA fragmentation rate Chances of conception Less than 15% Normal From 15 to 30% Moderate More than 30% Low How to read a DNA Fragmentation test The test includes the DNA fragmentation rate &#8220;%SDF&#8221;, which indicates the percentage of DNA fragmentation in the sperm head. The result is considered normal if it is less than 15%, while fertility is slightly affected if the result is 15\u201330%. An increase above 30% is associated with low chances of conception. When do you need a sperm DNA fragmentation test? An andrologist may request a sperm DNA fragmentation test in the following cases: Requirements for a sperm DNA fragmentation test The test requires a semen sample. Below are the requirements for collecting the sample: How is a sperm DNA fragmentation test performed? There is more than one technique to measure the percentage of DNA fragmentation in a semen sample, such as: How long does a sperm DNA fragmentation test take? The duration of the sperm DNA fragmentation test varies by lab and test type. Typically, the result appears within a few days after submitting the semen sample. Causes of sperm DNA fragmentation There are several reasons behind increased sperm DNA fragmentation, such as: 1. Increased reactive oxygen species (ROS) Increased reactive oxygen species lead to oxidative stress, which causes many types of damage to the body\u2019s cells, including sperm. Reactive oxygen species increase the man\u2019s DNA fragmentation rate, in addition to increasing the rate of sperm abnormalities, which affects his ability to conceive. Natural antioxidants protect the body from this damage, so the DNA fragmentation rate increases when antioxidants are deficient. 2. Varicocele Varicocele affects about 15% of men and is one of the most prominent causes of reduced sperm quality. According to some recent studies, men with varicocele are more prone to DNA fragmentation in the sperm head, and varicocele also increases reactive oxygen species. 3. Infection Medical reports indicate that some types of bacterial infections in the urinary or reproductive tract increase sperm DNA fragmentation, such as &#8220;Chlamydia&#8221; and &#8220;Mycoplasma&#8221; infections. 4. Testicular temperature The testicles have a relatively lower temperature than the body to ensure the highest-quality sperm production. However, when testicular temperature rises, sperm quality decreases and DNA fragmentation increases. Therefore, it is recommended to avoid placing a laptop directly on the thighs and to avoid tight clothing to prevent increased testicular temperature. 5. Weight gain Obesity causes many health problems and is also one of the causes of sperm DNA fragmentation, as weight gain leads to: 6. Reproductive tract inflammation Reproductive tract inflammation, such as epididymitis or prostatitis, affects semen and sperm quality. Inflammation also increases reactive oxygen species, thereby increasing the semen fragmentation rate in men. 7. Smoking Smoking is one of the causes of poor sperm quality, and long-term smoking may lead to: Frequent exposure to cigarette smoke may also cause the same damage as smoking, even if you are not a smoker. 8. Chemotherapy and radiotherapy Treating some cancers requires radiotherapy sessions or chemotherapy. However, these treatments may affect testicular function and male fertility in several ways, including increasing the sperm DNA fragmentation rate. Symptoms of increased sperm DNA fragmentation In fact, there are no specific symptoms of increased sperm DNA fragmentation except delayed conception. Your doctor may recommend a sperm DNA fragmentation test in the following cases: Treatment of sperm DNA fragmentation in men Treatment of sperm DNA fragmentation depends on preventing negative factors that affect testicular function, which helps improve sperm quality and reduce DNA fragmentation. Therefore, treatment may include the following: 1. Taking antioxidants Antioxidants are an effective treatment for sperm DNA fragmentation caused by oxidative stress &#8220;Oxidative stress&#8221;, which occurs when reactive oxygen species increase. Several studies have reported&#8230;<\/p>\n","protected":false},"author":193833143,"featured_media":8719,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_wpcom_ai_launchpad_first_post":false,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_post_was_ever_published":false,"_members_access_role":[],"_members_access_error":""},"categories":[409],"tags":[426,423,424,422,425],"class_list":["post-8720","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-delayed-conception","tag-causes-of-increased-sperm-dna-fragmentation-rate","tag-dna-structure","tag-sperm-dna","tag-sperm-dna-fragmentation","tag-what-is-sperm-dna-fragmentation"],"yoast_head":"<!--
