Comment on "Aşır et al. Investigation of Vitamin D Levels in Men with Suspected Infertility

In response to the insightful comments made by Dr. Abid et al. on our article "Investigation of Vitamin D Levels in Men with Suspected Infertility", we address several key points concerning the generalizability and methodology of our study. Dr. Abid et al.'s critique primarily focused on the single-center nature of our research, regional variations in ultraviolet (UV) exposure, dietary factors affecting vitamin D levels, and the sample size of our study. We discuss the inherent value and controlled environment of single-center studies while acknowledging the need for multi-center validation. Additionally, we explain our consideration of sun exposure and dietary intake in our analysis, and recognize the importance of larger, more diverse studies to strengthen our findings. Our response aims to clarify these aspects and emphasize the significance of vitamin D in male infertility, encouraging further research in this field.
