ABSTRACT
The massification of technologies, the implementation of 5G and the Internet of Things (IoT), allow implementing systems that contain virtual or augmented reality or implementation of both. In this sense, the covid 19 pandemic in the last years, has also affected people's behavior and leaned to shop without leaving their homes. VR, RA, and/or MR techniques are currently widely used for medicine, education, and entertainment, among others. In this study, we combine both elements to analyze the literature on e-commerce and the use of VR, AR, and/or RM. Searching and analyzing recent scientific articles were defined, and virtual reality is the most used, followed by the mixture of RV and RA, the above to improve the shopping experience, providing the customer with a more authentic and immersive environment. In future works, we will expect to expand this study, including how to evaluate the shopping experience and relate it to the customer experience. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
ABSTRACT
Objective: To determine if COVID-19 vaccination has a significant influence on parameters considered important for Assisted reproductive technology (ART) in men. Material(s) and Method(s): Retrospective analysis of 70 male patients, investigating semen volume (mL), concentration (x106), percent sperm motility, Progression, total motile sperm count (TMC) (x106) respectively with respect to COVID-19 vaccination status. A total of 70 male patients/donors were included in the analysis. Patients were stratified into two groups based on the COVID-19 vaccination such that 36 patients received at least a single dose of vaccine and 34 did not received any dose of vaccine. Data was structured within each group with respect to aspects like semen volume (mL), concentration (x106), percent sperm motility, Progression, total motile sperm count (TMC) (x106) respectively. Statistical analysis included two-tailed Student's t-test for continuous variables, Chi-squared test for categorical variables, Pearson correlation for correlation matrix analysis, with p<0.05 defining statistical significance. GraphPad Prism (GraphPad Software) was used for statistical analysis. Result(s): We compared semen volume (mL), concentration (x106), percent sperm motility, Progression, total motile sperm count (TMC) (x106) respectively between the vaccinated (n=36) and non-vaccinated (n=34) male patients/donors. Results showed that there was no significant difference between the two groups in context of each of the considered parameters (p>0.05). Conclusion(s): Our findings suggest that COVID-19 vaccination does not affect semen volume (mL), concentration (x106), percent sperm motility, progression, total motile sperm count (TMC) (x106) respectively. Further studies are required to find If additional parameters, such as sperm sorting methods, BMI, age, Testosterone, Leutinizing hormones (LH), Follicular stimulating hormones (FSH) which could be influenced by COVID-19 vaccination. Together these studies will help to overcome vaccine hesitance and establish a clear understanding about vaccines in the context of clinical variables that are considered relevant to ART for successful IVF outcomes. Impact Statement: Our findings will help in understanding of the impacts of COVID-19 vaccination on parameters which are considered important for assisted reproductive technology with respect to male partner.
