Effects of Chronic Musculoskeletal Pain on Fertility Potential in Lean and Overweight Male Patients

Table 4

Median (25–75 percentiles) kinematic parameters of sperm motility in overweight with chronic pain (OP), overweight control (OC), lean with chronic pain (LP), and lean control (LC) groups. Superscripted letters mark pairwise significant differences (). Multivariate two-way analysis of variance (MANOVA) was used to compare differences in kinematic parameters.
