Objectives Abnormalities in the timing and course of spermatozoa capacitation and hyperactivation underlie common pathologies related to male infertility. Recent data shows that low frequency electromagnetic waves may influence cell membrane potential and permeability. It is therefore possible that low frequency electromagnetic waves could affect the maturation and motility processes of spermatozoa. The 43-kHz wave generator was used for modeling the impact of environmental exposure to low frequency electromagnetic radiation on human sperm. Material and Methods Sperm samples were gathered from 103 fertile, healthy men aged 25–30 years old and performed computer-assisted sperm analysis. After initial examination, each participant’s semen sample was divided into 2 aliquots (control and experimental) and placed in separate automated incubators. The samples constituting the experimental group were placed into the exposure system that emitted 43-kHz electromagnetic waves. Sperm motility was assessed at 3 h, 12 h and 24 h. Results Exposure to a 43-kHz radio frequency increased the percentage of sperm in progressive motility by up to 5.8% and the velocity of said sperm by up to 2 μm/s. Moreover, the total number of hyperactivated spermatozoa was significantly increased in the semen exposed to the electromagnetic signal. Conclusions In vivo environmental exposure to 43-kHz waves may promote the development of infertility related to premature capacitation outside of the vaginal tract. Exposing semen to this particular frequency may also boost the capacitation and hyperactivation of spermatozoa in vitro, prior to conducting assisted reproductive therapies.Int J Occup Med Environ Health 2018;31(6):723–739

Introduction: Contemporary psychology of health pays a lot of attention to issues of personal and social resources, perceiving them as factors which favour the individual’s health and quality of life. Scientific studies confirm a positive sense of the possibility to express emotions during hospitalization, operative treatment and convalescence. Studies on the Courtauld Emotional Control Scale (CECS) in women during the perioperative period, treated for gynaecological ailments, may enable identification of patients exhibiting deficits in this respect, who should be covered by a special psychopreventive care. Methods: The studies involved 232 women treated surgically for various gynaecological ailments and were carried out in two stages: on the day preceding the surgery and on the third day after the surgery. The studies were carried out using the Courtauld Emotional Control Scale. The obtained results were analysed statistically. Results: The level of negative emotions control was higher in patients aged over 40, as compared to that in younger women. The category of operative procedure did not condition the level of emotional control, whether in the Total scale or in subscales of Anger, Depression and Anxiety in the preoperative period. On the other hand, in the postoperative period a higher suppression of emotions within the Anxiety subscale wasfound in women after operation with a major injury of tissues, as compared to the patients after operation with a minor injury of tissues. Conclusions: The values of the total level of the Courtauld Emotional Control Scale (total CECS) obtained in our studies, as well as in the subscales of Anger, Depression and Anxiety point to women’s tendency to suppress negative emotions in the perioperative period.

Wstęp: Współczesna psychologia zdrowia poświęca wiele uwagi problematyce zasobów osobistych i społecznych, upatrując w nich czynniki sprzyjające zdrowiu i jakości życia jednostki. Badania naukowe potwierdzają pozytywne znaczenie możliwości wyrażania emocji w okresie hospitalizacji, leczenia chirurgicznego i rekonwalescencji. Badania poziomu kontroli emocji (CECS) u kobiet w okresie okołooperacyjnym, leczonych z powodów ginekologicznych, mogą umożliwić identyfikowanie pacjentek przejawiających deficyt w tym zakresie, które powinny być objęte szczególną opieką psychoprofilaktyczną. Metody: Badaniami objęto 232 kobiety leczone operacyjnie z różnych powodów ginekologicznych. Badania przeprowadzono w dwóch etapach: w dniu poprzedzającym operację oraz w trzeciej dobie po operacji. Badania przeprowadzono przy użyciu Skali Kontroli Emocji. Uzyskane wyniki badań poddano analizie statystycznej. Wyniki: Poziom kontroli emocji negatywnych był wyższy u pacjentek w wieku powyżej 40 lat aniżeli u kobiet młodszych. Kategoria zabiegu operacyjnego nie warunkowała poziomu kontroli emocji, zarówno w skali Ogólnej, jak i w podskalach Gniew, Depresja i Lęk w okresie przedoperacyjnym. Natomiast w okresie pooperacyjnym stwierdzono większe tłumienie emocji w zakresie podskali Lęku u kobiet po operacji ze znacznym urazem tkanek aniżeli u badanych po operacji z miernym urazem tkanek. Wnioski: Stwierdzone w badaniach własnych wartości ogólnego wskaźnika kontroli emocji (CECS ogólny), jak również w podskalach Gniew, Depresja i Lęk wskazują na tendencję do tłumienia przez kobiety emocji negatywnych w okresie okołooperacyjnym.

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.
