The short answer is no, though there may be temporary side effects to consider. Let\u2019s explore what the research says about how vaccines work and why they are deemed safe for those trying to conceive.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Key takeaways<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Vaccines work to help the body develop immunity to specific diseases by exposing them to small pieces of the virus or bacteria that causes the disease.<\/li>\n\n\n\n<li>There is no evidence that any vaccines, including <a href=\"https:\/\/www.givelegacy.com\/resources\/will-the-covid-19-vaccine-affect-male-fertility\/\">COVID-19 vaccines<\/a>, can cause long-term fertility problems in males or females.<\/li>\n\n\n\n<li>Fevers associated with vaccines may cause a <strong>temporary<\/strong> decline in sperm count or quality.<\/li>\n\n\n\n<li>Studies indicate that, while some diseases \u2014 including <a href=\"https:\/\/www.givelegacy.com\/resources\/covid-19-male-fertility\/\">COVID-19<\/a>, mumps, <a href=\"https:\/\/www.givelegacy.com\/resources\/stis-stds-sperm-health-fertility\">HPV<\/a>, and hepatitis \u2014&nbsp; may affect fertility, getting vaccinated for the same diseases did not affect fertility at all, and may be protective for fertility.<\/li>\n<\/ul>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">How vaccines work<\/h2>\n\n\n\n<p>Vaccines help the body develop immunity to specific diseases caused by viruses or bacteria. Vaccines typically introduce a small, inactive amount or piece of the \u201cpathogen,\u201d or germ. While this pathogen won\u2019t cause illness, it will trigger the immune system to produce antibodies as if it were actually exposed to the disease.<\/p>\n\n\n\n<p>Afterward, the body is left with a supply of antibodies, T-lymphocytes, and B-lymphocytes (also known as T-cells and B-cells) \u2014 immune cells that will be able to fight off that disease if you\u2019re exposed in the future. In this sense, vaccines are like personal trainers for your immune system; they prepare the body for future challenges.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Types of vaccines<\/h3>\n\n\n\n<p>The types of vaccines available in the US include live attenuated vaccines, inactivated vaccines, toxoid vaccines, subunit vaccines, mRNA vaccines, and viral vector vaccines. Let\u2019s briefly review how each one works.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading\">Live attenuated vaccines<\/h4>\n\n\n\n<p>Live attenuated vaccines contain a weakened version of a living virus or bacteria that can replicate in the body without causing illness.&nbsp;<\/p>\n\n\n\n<p>Examples of live attenuated vaccines:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Measles, mumps, and rubella (MMR) vaccine<\/li>\n\n\n\n<li>Varicella (chickenpox) vaccine<\/li>\n\n\n\n<li>Some seasonal flu vaccines<\/li>\n<\/ul>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading\">Inactivated vaccines<\/h4>\n\n\n\n<p>Inactivated vaccines use a dead version of the virus or bacteria. Though it can\u2019t replicate, it can still trigger an immune response. Multiple doses may be needed to build up and\/or maintain immunity.<\/p>\n\n\n\n<p>Examples of inactivated vaccines:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Polio vaccine<\/li>\n\n\n\n<li>Some seasonal flu vaccines<\/li>\n<\/ul>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading\">Toxoid vaccines<\/h4>\n\n\n\n<p>Some illnesses are caused by toxins produced by bacteria, as opposed to the bacteria itself. A toxoid vaccine introduces an inactive form of that toxin to produce immunity.<\/p>\n\n\n\n<p>Examples of toxoid vaccines:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Diphtheria vaccine (included in the DTaP or Tdap combination vaccines)<\/li>\n\n\n\n<li>Tetanus vaccine (included in the DTaP or Tdap combination vaccines)<\/li>\n<\/ul>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading\">Subunit vaccines<\/h4>\n\n\n\n<p>Subunit vaccines use only specific pieces of a pathogen to trigger an immune response. They&#8217;re also called \u201cacellular\u201d vaccines, referring to the fact that they don\u2019t contain a whole cell.<\/p>\n\n\n\n<p>Examples of subunit vaccines:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Pertussis or \u201cwhooping cough\u201d vaccine (included in the DTaP or Tdap combination vaccines)<\/li>\n\n\n\n<li>Hepatitis B vaccine<\/li>\n<\/ul>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading\">mRNA vaccines<\/h4>\n\n\n\n<p>Instead of actually containing the pathogen to which they hope to induce immunity, mRNA vaccines contain a type of messenger code that teaches cells to make a subunit of a virus. That piece of the virus then triggers the immune response to create antibodies.<\/p>\n\n\n\n<p>Examples of mRNA vaccines:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Pfizer-BioNTech and Moderna <a href=\"https:\/\/www.givelegacy.com\/resources\/will-the-covid-19-vaccine-affect-male-fertility\/\">vaccines for COVID-19<\/a>, which teach cells to create a controlled amount of the \u201cspike protein\u201d found on the surface of the coronavirus SARS-CoV-2<\/li>\n<\/ul>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading\">Viral vector vaccines<\/h4>\n\n\n\n<p>Like mRNA vaccines, viral vector vaccines teach cells how to make a particular protein from a virus, triggering the creation of antibodies. In viral vector vaccines, the code is carried inside a modified version of a different virus.<\/p>\n\n\n\n<p>Examples of viral vector vaccines:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Johnson &amp; Johnson-Janssen and AstraZeneca <a href=\"https:\/\/www.givelegacy.com\/resources\/will-the-covid-19-vaccine-affect-male-fertility\/\">COVID-19 vaccines<\/a>, which teach cells to create a controlled amount of the \u201cspike protein\u201d found on the surface of the coronavirus SARS-CoV-2<\/li>\n\n\n\n<li>Ebola vaccine (still in clinical trials)<\/li>\n<\/ul>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Have vaccines ever been shown to affect male fertility?<\/h2>\n\n\n\n<p>The short answer: no, vaccines will not impact fertility in the long term.<\/p>\n\n\n\n<p>There is no evidence that any vaccines, including <a href=\"https:\/\/www.givelegacy.com\/resources\/will-the-covid-19-vaccine-affect-male-fertility\/\">COVID-19 vaccines<\/a>, cause long-term fertility problems in males or females. And because many infections may affect fertility, getting up-to-date on your vaccines may be an important step in <a href=\"https:\/\/www.givelegacy.com\/resources\/the-6-things-all-couples-should-do-before-they-try-to-conceive\/\">preparing to get pregnant<\/a> or try to get your partner pregnant.<\/p>\n\n\n\n<p>However, some vaccines may cause a fever. Research suggests that there may be a temporary <a href=\"https:\/\/www.givelegacy.com\/resources\/fever-sperm-quality-and-fertility\/\">decline in fertility after a fever<\/a> \u2014 however, research is mixed on whether the short fever associated with vaccination will have a significant effect on sperm count or quality.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/www.givelegacy.com\/vnext\/wp-content\/uploads\/2022\/05\/vaccines-and-male-fertility-fever-sperm-DNA-fragmentation-1024x683.jpg\" alt=\"\" class=\"wp-image-11319\" srcset=\"https:\/\/www.givelegacy.com\/vnext\/wp-content\/uploads\/2022\/05\/vaccines-and-male-fertility-fever-sperm-DNA-fragmentation-1024x683.jpg 1024w, https:\/\/www.givelegacy.com\/vnext\/wp-content\/uploads\/2022\/05\/vaccines-and-male-fertility-fever-sperm-DNA-fragmentation-300x200.jpg 300w, https:\/\/www.givelegacy.com\/vnext\/wp-content\/uploads\/2022\/05\/vaccines-and-male-fertility-fever-sperm-DNA-fragmentation-768x512.jpg 768w, https:\/\/www.givelegacy.com\/vnext\/wp-content\/uploads\/2022\/05\/vaccines-and-male-fertility-fever-sperm-DNA-fragmentation.jpg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Fever and semen parameters<\/h3>\n\n\n\n<p>One of the most common side effects associated with vaccines is a low fever, which can occur directly after or up to several days after getting vaccinated. Fever is an expected side effect of vaccination, and indicates that the immune system has kicked into gear and is building its defenses.<\/p>\n\n\n\n<p>However, high body temperatures may negatively affect <a href=\"https:\/\/www.givelegacy.com\/sperm-quality\/\">sperm quality<\/a>. Sperm are produced most optimally at around 93.2\u00baF. This is why the testes hang away from the body \u2014 to ensure the temperature inside the scrotum is lower than body temp. Fevers can temporarily increase the temperature inside the scrotum.<\/p>\n\n\n\n<p>Research suggests that, depending on the number of hours or days you experience a fever, it may significantly affect your semen parameters (or measures of sperm health). Semen parameters include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Sperm concentration: how many sperm are present in the semen<\/li>\n\n\n\n<li>Motility: what percentage of sperm are moving or \u201cswimming\u201d<\/li>\n\n\n\n<li>Morphology: what percentage of sperm are the right size, shape, and structure<\/li>\n<\/ul>\n\n\n\n<p>One small study found that there was a large variation in an individual person\u2019s response to fever. In general, each day of a fever was associated with:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A 7.1\u20138.5% decrease in sperm concentration<\/li>\n\n\n\n<li>A 4.5% decrease in motile sperm<\/li>\n\n\n\n<li>A 1.6% decrease in morphologically normal sperm<\/li>\n<\/ul>\n\n\n\n<p>Other studies of <a href=\"https:\/\/www.givelegacy.com\/resources\/fever-sperm-quality-and-fertility\/\">fever and male fertility<\/a> have found this effect is temporary, and semen parameters tend to recover gradually after a fever has resolved. The testes are making sperm constantly, in a process that takes about 72 days. A <a href=\"https:\/\/www.givelegacy.com\/resources\/fever-sperm-quality-and-fertility\/\">fever can affect sperm<\/a> in any stage of development. That means that, after a fever, a person could have altered sperm health for up to 3 months, depending on the severity of the fever.<\/p>\n\n\n\n<p>Fever may also affect sperm\u2019s genetic health, or <a href=\"https:\/\/www.givelegacy.com\/sperm-dna-fragmentation\/\">DNA fragmentation<\/a>. A <a href=\"https:\/\/onlinelibrary.wiley.com\/doi\/abs\/10.1002\/j.1939-4640.2000.tb02142.x\">2013 study<\/a> found that a one-day fever associated with influenza had effects on sperm chromatin structure, which resulted in the release of genetically abnormal sperm. At 18 days post-fever, 36% of sperm contained \u201cdenatured\u201d or abnormal DNA This percentage decreased gradually as days progressed, again indicating that the effects were temporary.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading\">Will a vaccine-induced fever actually affect male fertility?<\/h4>\n\n\n\n<p>It\u2019s also important to note that, in the studies above, the fevers were induced by illnesses, not vaccines. They tended to be higher, around 103\u00b0F, while fevers caused by vaccines tend to be lower, less than 102\u00baF. Vaccine-induced fevers are also likely to be shorter, <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC6658305\/\">lasting around 8\u201316 hours<\/a>.<\/p>\n\n\n\n<p>Not everyone who gets a vaccine will get a fever. For example, <a href=\"https:\/\/www.cdc.gov\/vaccines\/covid-19\/info-by-product\/pfizer\/reactogenicity.html\">about 16%<\/a> of people who got the Pfizer COVID-19 vaccine had a fever after the second dose. Some vaccines require more than one dose to be effective, and fevers may be more likely after later doses.<\/p>\n\n\n\n<p>So, while fever after vaccination is a theoretical temporary risk to male fertility, it hasn\u2019t always been shown to affect semen parameters in practice. One <a href=\"https:\/\/jamanetwork.com\/journals\/jama\/fullarticle\/2781360\">study<\/a> examined the semen parameters of 45 healthy men before and after vaccination with a Pfizer or Moderna mRNA vaccine. Researchers found no decline in sperm count or motility after vaccination.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Long-term effects of vaccines on male fertility?<\/h3>\n\n\n\n<p>Clinical trials, follow-up studies, and safety monitoring indicates that no vaccines currently on the market have a long-term impact on semen parameters or male fertility.<\/p>\n\n\n\n<p>In fact, vaccination may be an important step to protecting fertility from illnesses and diseases that <em>can <\/em>negatively affect sperm health. Several studies have indicated that, while some infections are known to affect fertility, getting vaccinated for those same infections did not affect fertility at all.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading\">HPV vaccine and male fertility<\/h4>\n\n\n\n<p><a href=\"https:\/\/www.givelegacy.com\/resources\/stis-stds-sperm-health-fertility\">Human papillomavirus (HPV)<\/a> is associated with <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC3739240\/\">infertility in male patients<\/a>.<\/p>\n\n\n\n<p>A <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/20836123\/\">2010 animal study<\/a> found that the HPV vaccine has no effects on fertility. After receiving the vaccine, the reproductive markers of male rats, including histomorphology of testes and epididymis, sperm count, and sperm motility, were not impacted.<\/p>\n\n\n\n<p>Interestingly, in one trial, vaccinating men who <em>already<\/em> had HPV actually <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC5772512\/\">improved their fertility<\/a> \u2014 and pregnancy rates were significantly higher in the vaccine group compared to the control group. This is likely because the vaccine triggered action by the immune system to fight the pre-existing infection.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading\">Hepatitis vaccine and male fertility<\/h4>\n\n\n\n<p>Similarly, <a href=\"https:\/\/www.fertstert.org\/article\/S0015-0282(14)02169-4\/fulltext\">studies<\/a> show that individuals infected with hepatitis are at higher risk for infertility.<\/p>\n\n\n\n<p>Hepatitis vaccines, on the other hand, are <a href=\"https:\/\/www.fertstert.org\/article\/S0015-0282(08)03525-5\/fulltext\">recommended<\/a> for individuals hoping to conceive a child, and are regularly administered to pregnant people and children to prevent illness and associated fertility issues.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">What about the COVID-19 vaccine?<\/h3>\n\n\n\n<p>Misinformation about COVID-19 vaccines negatively affecting fertility has persisted throughout the pandemic.

A <a href=\"https:\/\/jamanetwork.com\/journals\/jama\/fullarticle\/2781360\">study<\/a> by the University of Miami confirmed similar findings in 45 male participants after 70 days.
