    Introduction and objective. The male reproductive system constitutes a set of tissues which are particularly sensitive to external factors. The aim of the study was to analyze the relationship between background radioactivity and the quality of the semen of the men who have reported to the infertility treatment facility in 2000–2016 in the Lublin region of eastern Poland. Materials and method. The radioactivity of the ground-level air layer obtained from the Institute of Meteorology and Water Management in Włodawa in the Lublin region was analysed. 4,250 spermiograms of patients who reported to the treatment facility for the first time due to infertility were analysed and correlated to background radioactivity in the Lublin region in 2000–2016. Results. A long-term decrease in the percentage of morphologically normal spermatozoa of the patients was observed (r=-0.970; p<0.001 in 2000–2009 and r=-0.925; p=0.003 in 2010–2016). Men’s age correlated negatively with sperm motility (r=-0.164; p=0.009) and morphology (r=-0.186; p=0.009). The percentage of spermatozoa with normal morphology was lowered by beta-isotopes of artificial origin in the air in 2000–2009 (r=-0.655; p=0.040) and by the exposure to gamma radiation of the ground-level atmosphere in 2010–2016 (r=-0.676; p=0.048). The percentage of sperm vitality was lowered by gamma radiation in the atmosphere (r=-0.636; p=0.006), but improved by beta isotopes in precipitation (r=0.686; p=0.002) in the whole of the analyzed period. Conclusions. The percentage of morphologically normal spermatozoa in patients who reported to the infertility treatment depends not only on the age of patient, but also on beta-isotopes of artificial origin and gamma radiation in the atmosphere. Beta isotopes in precipitation affect the improvement of sperm vitality.

    Opis:
    Objectives The purpose of this paper was to analyze the relationship between the selected chemical air pollutants found in the Lublin Province and the semen parameters of men seeking fertility treatment for the first time. Material and Methods The study involved an analysis of semen sample test results obtained from male patients first reporting for fertility treatment in reproductive health centers in the Lublin Province, Poland. The data set comprises semen parameters of 13 148 men, and the number of samples in the reference period was 255–769 annually. Data on air pollution were obtained from the website of the Polish General Environmental Inspectorate and included selected chemical air pollutant levels, i.e., NO₂, SO₂, O₃, and PM₁₀. Results The mean PM₁₀ levels in the air increased, on average, by 0.65 μg/m₃ annually in 2000–2015 (p = 0.029); the mean levels of O₃, NO₂, SO₂ did not change significantly in the analyzed period. There were increasing trends in the mean sperm density and total sperm count of the subjects in 1992–2015 (p < 0.001). The mean percentage of sperm with normal morphology significantly decreased in the subsequent analysis periods: 1992–1998 (p = 0.001); 1999–2009 (p < 0.001); 2010–2015 (p = 0.001). A significant negative correlation was found between the ozone levels in the air in the Lublin Province and the percentage of sperm with normal morphology (r = –0.8311, p = 0.040). Conclusions Exposure to ozone in the air contributes to decreased percentages of sperm with normal sperm morphology. Over the years, there was an increasing trend in sperm density in the men first reporting for fertility treatment, and a decreasing trend in the percentage of sperm with normal morphology.

    Opis:
    Over the last 40 years, the quality of male semen, including the sperm count, has decreased. There are numerous reasons for this phenomenon, including occupational and environmental exposure to heavy metals such as cadmium, lead, mercury and arsenic. Food contaminated with mycotoxins and pesticides, the influence of industrial chemicals, cigarette smoking and endocrine factors are also of great significance. This paper discusses the problem based on the literature of the last few years on the role of physiologically occurring metals in semen and the effect that heavy metals have on decreasing male fertility.
    Na przestrzeni ostatnich 40 lat spadła jakość nasienia męskiego, w tym m.in. liczba plemników. U podstaw tego zjawiska leży wiele przyczyn, wśród których wymienia się ekspozycję zawodową i środowiskową na metale ciężkie, m.in. na kadm, ołów, rtęć i arsen. Duże znaczenie ma również zanieczyszczona mykotoksynami i pestycydami żywność, wpływ chemikaliów przemysłowych, palenie papierosów i czynniki endokrynologiczne. Niniejsza praca stanowi omówienie problemu na podstawie piśmiennictwa z ostatnich kilku lat na temat roli metali fizjologicznie występujących w nasieniu oraz wpływu metali ciężkich na obniżenie płodności męskiej.

    Opis:
    Introduction. Man is the only being that has created an artificial environment, or civilization. The development of civilization entails changes in the environment. The rapid growth of the impact of human economic activity has led to such changes that are able to threaten not only other living creatures but also themselves. Increasing environmental pollution are well-known factors negative influencing on human environment. Is now a global problem. Anthropogenic pollution contribute to the unfavorable demographic changes and grooving number of health problems of the population. Unfavourable demographic changes manifest themselves as not only increment in the number of deaths and malformations (defects in the reproductive organs), but also as decrement in the fertility rates being the consequence of increasing the growing problem of couples infertility. There is observed the increasing role of male factor in the couple infertility problem. In some developed countries its participation rate reaches 50%.Objective. The aim of the study is to assess the impact of environmental pollution on human development and reproductive function of male gonads.Material and methods. The study was carried out using the method of data analysis published in the works and scientific reports.Current state of knowledge. The paper presents information on identified environmental pollution with proven adverse effects on the development of the gonads and the their reproductive function. There are also known possible negative impacts of environmental pollution on carcinogenesis in male gonads.Wider awareness of the negative impact of environmental pollution and attempts put emphasis on primary prevention can give better long-term effects than increasing spending on the therapies of developmental disorders as well as gonadal dysfunctions symptoms including fertility problems.Conclusions.Among the environmental pollutants there are many chemicals adversely affecting the organogenesis as well as reproductive function of testicles.Many of these contaminants are pesticides or chemicals currently approved for use in agriculture and industry, including the food and cosmetics industry.Those chemicals, adversely affecting organogenesis and testicular generative function, are present in air, water and foods, packaged foods and everyday objects - including clothes (ingredients sponges), perfumes, creams and detergents.The increase in environmental pollution coincides with the deterioration of sperm quality and reduction in male infertility in highly civilized countries.Striving for continuous reduction of the environmental seems to be necessary to stop the growing problem of couples infertility.

    Opis:
    Introduction. The human body is constantly exposed to an extremely low electromagnetic field (ELF-EMF), in particular at 50 Hz, emitted by power lines, domestic distribution lines, electrical appliances, etc. It is assumed that the increase in electromagnetic exposure may cause adverse effects upon human health, as well as raising concerns regarding the impact on human fertility. Objective. The aim of this in vitro study was to investigate the influence of ELF-EMF with a frequency of 50 Hz on the motility of human sperm. At the same time, the effectiveness of the dielectric screen constructed by ADR Technology® in absorbing the emitted radiation was examined. Materials and method. Semen samples of 20 patients were exposed to the influence of an extremely low electromagnetic field. After 5, 15 and 30 min., spermatozoa motility was analysed using a computer-assisted spermatozoa motility analysis system. The following sperm motility parameters were examined: 1) velocity straight linear motility; 2) cross-beat frequency; 3) lateral head displacement; 4) homogeneity of progressive motility velocity. Results. It was found that the ELF-EMF presented a negative effect on the motility of human spermatozoa. A significant decrease in spermatozoa motility speed and a significant increase in lateral head deviation values were observed under the influence of the electromagnetic field. ELF-EMF did not show an effect on either lateral head displacement or homogeneity of progressive motility velocity. Conclusions. A positive effect of the dielectric screen ADR Technology® was found. This effect compensated spermatozoa motility changes induced with ELF-EMF.

    Opis:
    Pathological lesions within the scrotum are relatively rare in imaging except for ultrasonography. The diseases presented in the paper are usually found in men at the age of 15–45, i.e. men of reproductive age, and therefore they are worth attention. Scrotal ultrasound in infertile individuals should be conducted on a routine basis owing to the fact that pathological scrotal lesions are frequently detected in this population. Malignant testicular cancers are the most common neoplasms in men at the age of 20–40. Ultrasound imaging is the method of choice characterized by the sensitivity of nearly 100% in the differentiation between intratesticular and extratesticular lesions. In the case of doubtful lesions that are not classified for intra-operative verifi cation, nuclear magnetic resonance is applied. Computed tomography, however, is performed to monitor the progression of a neoplastic disease, in pelvic trauma with scrotal injury as well as in rare cases of scrotal hernias involving the ureters or a fragment of the urinary bladder.
    Patologiczne zmiany w obrębie worka mosznowego są stosunkowo rzadko spotykane w badaniach obrazowych, z wyjątkiem ultrasonografii. Prezentowane choroby dotyczą najczęściej grupy mężczyzn w przedziale wiekowym 15–45 lat, czyli w wieku rozrodczym, dlatego zasługują na szczególną uwagę. U niepłodnych mężczyzn badanie ultrasonograficzne moszny powinno być wykonywane rutynowo, ponieważ w tej populacji częstość wykrywania zmian patologicznych w mosznie jest bardzo wysoka. Nowotwory złośliwe jąder należą do najczęstszych nowotworów występujących u mężczyzn w wieku 20–40 lat. Metodą diagnostyczną z wyboru jest badanie ultrasonograficzne, którego czułość w różnicowaniu zmian wewnątrzjądrowych i zewnątrzjądrowych wynosi prawie 100%. W diagnostyce niejednoznacznych zmian, niekwalifikujących się do weryfikacji operacyjnej, stosowany jest magnetyczny rezonans jądrowy. Tomografię komputerową natomiast wykorzystuje się w monitorowaniu zaawansowania choroby nowotworowej, w stanach pourazowych miednicy z udziałem urazu moszny oraz w rzadkich przypadkach przepuklin mosznowych zawierających moczowody lub fragment pęcherza moczowego.
