“…Additionally, exercise may strengthen the immune system, which is typically impaired in post-COVID men with reproductive / genital system issues. The following are some of the hypothesized mechanisms by which exercise may boost immunity in different body parts including the reproductive / genital system: (a) increasing T-lymphocytes, neutrophils, macrophages, and monocytes, which are essential components of the body's defense system against infectious diseases; (b) increasing immunoglobulin levels; and (c) preventing the rise of high circulating levels of C-reactive protein and pro-inflammatory markers [13,14]. Correction of systemic inflammatory milieu may be associated with improvement in the localized testicular inflammation, hence sperm production and quality may improve.…”
