male\u2019s age have an impact on his spermatozoids?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>There are published studies that show that\u00a0<strong>the male\u2019s age is related to a higher likelihood of an increased amount of\u00a0<u>sperm with chromosome abnormalities,\u00a0<\/u><\/strong><u>which can in turn lead to genetic risks for their offspring<\/u>\u00a0in addition to miscarriage, implantation failure, etc.<\/p>\n<p>As with DNA fragmentation,\u00a0<strong>there are also diagnostic tests to detect the presence of these types of abnormalities,<\/strong>\u00a0as well as the<strong>\u00a0<a href=\"https:\/\/urecentrogutenberg.es\/en\/pre-implantation-genetic-diagnosis\/\" target=\"_blank\" rel=\"noopener\">pre-implantation genetic diagnosis<\/a>\u00a0<\/strong>which can be performed as part of\u00a0<strong><u>in vitro fertilisation<\/u>\u00a0treatment.<\/strong><\/p>\n<p><strong>The Pre-Implantation Genetic Diagnosis is a

rel=\"noopener\">embryo transfer<\/a>.<\/strong>\u00a0It is a genetic examination of the cells in the embryo to determine whether they carry any chromosome abnormalities, in turn allowing us to select only healthy embryos to transfer to the uterus.<\/p>\n<p>We must point out that there is a lot of controversy surrounding this last point, and paternal age alone would not be reason enough to suggest the use of pre-implantation genetic diagnosis as part of a couple\u2019s treatment.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"The_fathers_age_and_the_babys_health\"><\/span>The father\u2019s age

are not very conclusive.\u00a0<strong>There are also publications that have shown a slight increase in the likelihood of autism and schizophrenia in offspring, also currently under debate.<\/strong><\/p>\n<p>But it is not only age that affects sperm quality: a recent study on a large number of participants from over 50 countries has concluded that<strong>\u00a0sperm quality is at a historical low<\/strong>, indicating that sperm concentration has dropped by half over the last 50 years. Specifically, sperm concentration has decreased from 101 million sperm per millilitre in 1973 to 49 million\/ml in 2018.<\/p>\n<p>There are currently several theories on the reason behind this decreased sperm quality, but there is clearly a direct relationship to the world we have created.\u00a0<strong>Exposure to contaminants (<a href=\"https:\/\/urecentrogutenberg.es\/en\/endocrine-disruptors-and-fertility-what-are-they-and-how-do-they-affect-fertility\/\" target=\"_blank\" rel=\"noopener\">endocrine disruptors<\/a>) from the time we are in our mothers\u2019 wombs and poor daily habits that negatively impact our fertility are exponentially related.<\/strong><\/p>\n<p>For this reason, at\u00a0<strong>URE Centro Gutenberg<\/strong>\u00a0we don\u2019t want to end this article without first reminding you that\u00a0<strong>you can control several of these factors and improve your fertility by clicking\u00a0<a href=\"https:\/\/urecentrogutenberg.es\/en\/habits-help-boost-male-fertility\/\" target=\"_blank\" rel=\"noopener\">here.<\/a><\/strong><\/p>\n<p>Have you been trying to conceive for some time but haven\u2019t been successful yet?
