To investigate whether the sperm concentration of European men is deteriorating over the past 50 years of time. We analysed the data published in English language articles in the past 50 years in altering sperm concentration in European men. A time-dependent decline of sperm concentration (r = −0.307, p = 0.02) in the last 50 years and an overall 32.5% decrease in mean sperm concentration was noted. This comprehensive, evidence-based meta-analysis concisely presents the evidence of decreased sperm concentration in European male over the past 50 years to serve the scientific research zone related to male reproductive health.

Reports regarding the changes in sperm concentration in different counties of the world are inconsistent. Furthermore, the reports that sprung up from specific epidemiological and experimental examinations did not include data of prior studies or geographical variations. The current study, following a previous report of massive fall in semen volume over the past 33 years, attempts to delineate the trend of altering sperm concentrations and factors responsible for this by reviewing article published from 1980 to July 2015 with geographic differences. The current study identified an overall 57% diminution in mean sperm concentration over the past 35 years ( r = −.313, p = .0002), which, when analyzed for each geographical region, identified a significant decline in North America, Europe, Asia, and Africa. An increasing trend of sperm concentration was identified only in Australia. The association of male age with such a trend ( R² = .979) is reported. The authors also correlated male fertility with sperm concentration. Thus, this comprehensive, evidence-based literature review aims to concisely and systematically present the available data on sperm concentration from 1980 to 2015, as well as to statistically analyze the same and correlate male health with the declining pattern of sperm count in a single scientific review to serve the scientific research zone related to reproductive health. It points to the threat of male infertility in times ahead.

Introduction: Aging has a strong influence on the quality of relationships and sexual functioning, but in itself does not cause a lack of sexual desire. Objectives: The aim of this study was to assess the quality of sexual life and define sexual knowledge and attitudes of older people on the example of residents of Bialystok, Poland at the age of 60 and over. Methods: The study included 170 people, inhabitants of Bialystok, Poland aged over 60: 85 students of the University of Healthy Senior and the University of Psychogeriatric Prophylaxis and 85 students of the University of the Third Age. The study used three standardized psychometric scales: Sexual Quality of Life Questionnaire-Male (SQoL-M), Sexual Quality of Life Questionnaire-Female (SQoL-F), and Aging Sexual Knowledge and Attitudes Scale (ASKAS). Results: The overall mean score for the ASKAS scale for knowledge was 65.21 ± 12.32 and for attitudes −124.65 ± 22.00. The overall mean SQOL score was 62.92 ± 18.18. Taking into account the gender of the respondents, the knowledge of men on sexuality of seniors was at the level of 63.48 ± 12.63, while in the female group −65.74 ± 12.23. The attitudes of men on sexuality of seniors was at the level of 128.80 ± 21.56, while in the female group −123.38 ± 22.05. Satisfaction with sex life among men (72.36 ± 27.49) was significantly higher than among women (60.02 ± 12.88). Discussion: The seniors were characterized by moderate knowledge and attitudes to sexuality of older people and the average level of sexual satisfaction. There was no significant relationship between knowledge on sexuality and sexual satisfaction in the study groups, and there was a positive correlation between attitudes toward sexuality and the satisfaction of sex life outside the group of men. In addition, a significant positive relationship was found between attitudes toward sexuality and sexual satisfaction. In order to improve the knowledge of senior citizens about sexuality of old age and to overcome the taboos that are prevalent in this topic, a structured training should be provided in this field. Such training should be carried out by specialists in the field of sexology. It is desirable to conduct in-depth studies in the assessment of knowledge, attitudes, and quality of sexual life in a larger research group, in order to get results for the population of the whole country.

Introduction Psoriasis is a complex disease with a heterogeneous presentation, which may have a profound effect on the everyday functioning of patients. As a strongly stressogenic disease, psoriasis may cause lack of illness acceptance and contribute to negative changes in self-image. Usually, psoriasis also has a detrimental effect on quality of life. The aim of this study is to determine the levels of illness acceptance, satisfaction with life, stigmatization, and quality of life in people with psoriasis, to analyze relationships among these variables, and to verify whether they are modulated by selected sociodemographic factors. Methods A total of 366 people with psoriasis treated at the Dermatology and Medical Cosmetology Clinic in Białystok were included. The study was conducted using a short survey prepared by the authors and five validated psychometric scales: Acceptance of Illness Scale (AIS), Satisfaction with Life Scale (SWLS), 6-item Stigmatization Scale, 33-item Feelings of Stigmatization Questionnaire, and Dermatology Life Quality Index (DLQI). Results Median AIS score was 24 pts, which corresponds to a moderate level of illness acceptance. The level of illness acceptance among men was significantly higher than among women. More than half of respondents assessed their satisfaction with life as low. Men showed low levels of satisfaction with life slightly more often than women. Patients living in the countryside showed high levels of satisfaction with life significantly more often than those living in cities/towns. Mean scores for the 6-item Stigmatization Scale and the 33-item Feelings of Stigmatization Questionnaire were 8.73 pts and 90.06 pts, respectively, with no significant differences between the results of male and female patients. The DLQI scores for the study group ranged between 0 and 30 pts, with the mean value of 17.81 pts corresponding to a severe deterioration of quality of life. Statistically significant differences between quality of life and all sociodemographic variables were demonstrated. Conclusions People with psoriasis participating in this study showed moderate levels of illness acceptance and stigmatization, low level of satisfaction with life, and moderately deteriorated quality of life. Acceptance of illness was significantly modulated by patient sex. The level of illness acceptance among men was significantly higher than among women. Furthermore, illness acceptance exerted a significant effect on satisfaction with life in psoriasis patients. Place of residence exerted significant effects on satisfaction with life (higher in countryside dwellers), sense of stigmatization (stronger in countryside dwellers), and quality of life (more severely deteriorated in city/town dwellers). Disease duration significantly affected the degree of life satisfaction, sense of stigmatization (measured using a 33-item Feelings of Stigmatization Questionnaire), and quality of life among patients with psoriasis.
