it may affect just one parotid gland, while in others it can affect both. <\/span><\/span><\/span><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\"><span

patients. <\/span><\/span><\/span><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">The MMR vaccine also provides protection

This also <\/span><span style=\"vertical-align: inherit;\">applies if you only develop orchitis in one testicle. <\/span><span style=\"vertical-align: inherit;\">It is only if the orchitis affects both testicles that the issue of fertility becomes important. <\/span><span style=\"vertical-align: inherit;\">Between <\/span><\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC1633545\/\"><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">10 and 30 per cent of men with mumps will develop orchitis in both testicles<\/span><\/span><\/a><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\"> and, of those men affected, a small number may experience a drop in fertility.\u00a0<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">For men, the biggest danger that mumps poses to fertility is if mumps-related orchitis results in testicular atrophy. <\/span><span style=\"vertical-align: inherit;\">This is what can lead to reduced sperm production. <\/span><span style=\"vertical-align: inherit;\">It is estimated that somewhere between <\/span><\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC1633545\/\"><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">30 to 50 per cent of mumps-related orchitis cases will show a degree of testicular atrophy<\/span><\/span><\/a><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\"> . <\/span><span style=\"vertical-align: inherit;\">It&#8217;s important to note, however, that this is unlikely to lead to infertility, rather a reduction in healthy sperm. <\/span><span style=\"vertical-align: inherit;\">Equally, while half may notice slight shrinkage of the affected testicle, it&#8217;s estimated just <\/span><\/span><a href=\"https:\/\/www.nhs.uk\/conditions\/mumps\/complications\/#:~:text=Just%20under%20half%20of%20all,large%20enough%20to%20cause%20infertility\"><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">one in 10 will see a reduction in their sperm count<\/span><\/span><\/a><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\"> . <\/span><span style=\"vertical-align: inherit;\">However, the drop is rarely severe enough to cause any fertility issues.<\/span><\/span><\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Mumps_infertility_and_the_prognosis_for_fatherhood\"><\/span><strong><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">Mumps, infertility and the prognosis for fatherhood<\/span><\/span><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">The good news is that mumps will very rarely lead to infertility. <\/span><span style=\"vertical-align: inherit;\">However, it may contribute to sub-fertility in some cases, which can make conceiving naturally a little bit harder. <\/span><span style=\"vertical-align: inherit;\">For anyone looking to start a family, it can be helpful to take steps to <\/span><\/span><a href=\"https:\/\/www.ivi.uk\/blog\/tips-preconception-health-men\/\"><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">ensure your fertility is in as good a shape as possible<\/span><\/span><\/a><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\"> . <\/span><span style=\"vertical-align: inherit;\">Many of these steps involve healthy lifestyle changes, such as cutting back on alcohol, quitting smoking and maintaining a healthy weight.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">Infertility can be harder to spot in men than in women, and it is often overlooked in conversations about reproductive issues. If you&#8217;re concerned about your fertility, one of the first steps is to book a sperm analysis test. <\/span><span style=\"vertical-align: inherit;\">This becomes particularly important if you have had mumps-related orchitis and find you are struggling to conceive. <\/span><span style=\"vertical-align: inherit;\">The simple test will determine the quality and the quantity of your sperm, and identify if there is an issue affecting your ability to conceive. <\/span><span style=\"vertical-align: inherit;\">Should a problem be found, there are a number of treatment options available at IVI, such as <\/span><\/span><a href=\"https:\/\/www.ivi.uk\/assisted-reproduction-treatments\/in-vitro-fertilisation\/\"><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">In Vitro Fertilization (IVF)<\/span><\/span><\/a><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\"> and <\/span><\/span><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">Intrauterine Insemination (IUI)<\/span><\/span><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\"> .<\/span><\/span><\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Mumps_and_infertility_are_on_the_rise_%E2%80%93_but_is_there_a_link\"><\/span><strong><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">Mumps and infertility are on the rise &#8211; but is there a link?<\/span><\/span><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">The MMR jab was first introduced in the UK in 1988 and this led to a steady decline in mumps cases. <\/span><span style=\"vertical-align: inherit;\">Prior to this, around 8 in 10 people developed mumps, the majority being of school age. <\/span><span style=\"vertical-align: inherit;\">A decade later in 1998, an MMR health scare meant many parents opted not to vaccinate their children, believing a now widely discredited paper that suggested a link between the MMR vaccine and autism.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">As a result, cases of mumps in the UK hit a decade high in 2019. That year, <\/span><\/span><a href=\"https:\/\/www.bbc.co.uk\/news\/health-51493496\"><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">cases of mumps were reported 5,042 times<\/span><\/span><\/a><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\"> , a figure that was four times higher than the 1,066 cases reported in 2018.
