<h2><span class="display-3">What is CMV (Cytomegalovirus)?</span></h2>
<p>Cytomegalovirus (CMV) is related to the herpes virus and is a common virus that can affect anyone. You can get infected through body fluids such as saliva, blood, urine, sperm and breast milk. Most people will get infected and become CMV positive during their childhood or early adulthood. Once infected, the virus lies dormant in the body forever, with little risk of getting reactivated. This is known as a recurrent CMV infection and is measured in CMV negative and CMV positive.</p>
<h3><span class="display-4">What are the most common CMV symptoms?</span></h3>
<p>The majority are without any symptoms but a few may develop fever, sore throat and headache. It can be hard to spot the symptoms of CMV infection since they are similar to the symptoms of typical flu. Here below we have made a list of the most common symptoms of CMV:</p>
<ul>
<li>Fever</li>
<li>Sore throat</li>
<li>Headache</li>
<li>Skin rash</li>
<li>Swollen glands</li>
</ul>
<p>If you experience any of these symptoms while being pregnant, you should consider contacting your doctor to schedule an appointment.</p>

<h2><span class="display-3">What is CMV status?</span></h2>
<p>Your CMV Status means to be either CMV positive or CMV negative. The first time you get infected you create antibodies called CMV IgM and CMV IgG. IgM antibodies are present during acute infection, IgG antibodies stay forever.</p>
<h3><span class="display-4">What is CMV positive?</span></h3>
<p>If you are CMV positive it means that you have been infected with the virus cytomegalovirus or CMV. Once you have been infected you create antibodies called CMV IgM and CMV IgG, which stay in your body forever. Here below, we have explained how it is possible to become CMV positive:</p>
<ul>
<li>When no IgM antibodies are present, but IgG antibodies are present, a person is CMV positive. This means that he/she has had a CMV infection in the past but does not have an acute infection.</li>
<li>When IgM and IgG antibodies are present, there is an acute infection. If a sperm donor has an acute infection with CMV, he/she cannot donate in that period.</li>
</ul>
<h3><span class="display-4">What is CMV negative?</span></h3>
<p>When no IgM antibodies nor IgG antibodies are present a person is CMV negative. This means that he/she has never been infected by CMV.<br><br></p>

<h2><span class="display-3"><br>What does CMV status mean in terms of choosing a sperm donor?</span></h2>
<p>We accept all types of donors, both CMV negative and CMV positive, as long as it is combined with a negative IgM (no current infection). Any donor with a CMV negative status in the <a href="/en-gb/dk-shop/private/find-donor/search-sperm-donors/" target="_top">Sperm Donor Search</a> has never had a CMV infection. Donors with a CMV positive status in the Donor Search have previously had a CMV infection and have antibodies.</p>
<p>Not all countries require CMV status screening. Therefore, the donors who have no CMV status shown in the Donor Search have not and will not be screened for CMV.</p>
<h2><span class="display-4">How Cryos screen sperm donors for CMV status</span></h2>
<p>At Cryos, we perform <a title="Read our extensive sperm donor screening" href="/en-gb/dk-shop/private/about-sperm/screening-of-sperm-donors/">sperm donor screening</a> on all the candidates for a wide variety of viruses and genetic disorders. We also screen our donors to check whether they are CMV positive or CMV negative to accommodate use in some countries. We accept only donors who have tested IgM negative. This means that the donors do not have an active CMV infection.</p>

<h2><span class="display-3">Chances of transmitting a CMV infection to your <span class="text-theme-blue-700">baby</span></span></h2>
<p>The chances of transmitting a CMV infection to your child depend on when you became infected the first time. Approximately 50% of women are CMV positive, which means that already have been infected and are close to immune to a CMV infection. You can risk a reactivation of the infection during pregnancy, but the risk of passing the virus to your baby during a recurrent infection is low (about 1-2 %). So, if you got your first CMV infection before your pregnancy, the risk of passing on the virus to your baby is very small.</p>
<p>If you are infected with CMV for the very first time during pregnancy, the chance of passing on the virus to your baby is higher.</p>
<h2><span class="display-3">Will my baby be affected by an acute CMV infection?</span></h2>
<p>Most babies with a CMV infection never show signs or have any health problems. Some babies infected with the virus during pregnancy may, however, have health problems that are apparent at birth or develop later during infancy or childhood. If you want to know more about CMV, we recommend that you speak with your doctor or clinic for advice. They can also test you if you are curious whether you are CMV positive or CMV negative.</p>
