Sperm are influenced by diet, and the effects arise rapidly. The study, which has been published in PLOS Biology , gives new insight into the function of sperm, and may in the long term contribute to new diagnostic methods to measure sperm quality. Sperm quality can be harmed by several environmental and lifestyle factors, of which obesity and related diseases, such as type 2 diabetes, are well-known risk factors for poor sperm quality. The research group that carried out the new study is interested in epigenetic phenomena, which involve physical properties or levels of gene expression changing, even when the genetic material, the DNA sequence, is not changed. In certain cases such epigenetic changes can lead to properties being transferred from a parent to offspring via the sperm or the egg. In a previous study, the scientists showed that male fruit flies which had consumed excess sugar shortly before mating more often produced offspring who became overweight.
Don't make the mistake of letting a diet kill sperm

This fact should scare everyone, especially men. However, sperm health is the last thing on the minds of most men. How nutrition impacts sperm is even farther away from our collective consciousness.
10 Ways to Boost Male Fertility and Increase Sperm Count
Following a healthy diet rich in foods such as fish, seafood, chicken, cereals, vegetables, and low-fat dairy or fruit can significantly improve sperm quality. On the contrary, a high consumption of alcohol, caffeine and red meat and processed in men can negatively influence the conception , according to a new research. Dietary patterns, components and nutrients have been studied for decades as possible determinants of sperm function or fertility. Many assisted reproductive clinics currently recommend simple lifestyle changes, such as increased physical activity, behavioral therapy, and yoga to reduce stress, as well as reduce alcohol and caffeine consumption. Some clinics even or provide dietary recommendations in order to improve semen quality and fertility possibilities, despite the lack of proven scientific evidence on the role of diet in sperm parameters.
A high-fat diet and obesity, resulting from an unhealthy lifestyle, affects the structure of spermatozoa, but also the development of offspring and their health in later stages of life. In obese individuals, disorders on the hypothalamic-pituitary-gonadal axis are observed, as well as elevated oestrogen levels with a simultaneous decrease in testosterone, luteinizing hormone LH , and follicle-stimulating hormone FSH levels. Healthy dietary models clearly correlate with better sperm quality and a smaller risk of abnormalities in parameters such as sperm count, sperm concentration and motility, and lower sperm DNA fragmentation. Apart from mineral components such as zinc and selenium, the role of omega-3 fatty acids and antioxidant vitamins should be emphasized, since their action will be primarily based on the minimization of oxidative stress and the inflammation process. Additionally, the incorporation of carnitine supplements and coenzyme Q10 in therapeutic interventions also seems promising.
