In the article titled “The Therapeutic Effects of a Traditional Chinese Medicine Formula Wuzi Yanzong Pill for the Treatment of Oligoasthenozoospermia: A Meta-Analysis of Randomized Controlled Trials” [1], there was an error in the Introduction, where the sentence “As one of the male infertility factors, Oligoasthenozoospermia is defined as the total number or concentration of spermatozoa and percentage of progressively motile spermatozoa, below the lower reference limits (total number < 33 × 10⁶ per ejaculate; concentration < 12 × 10⁶ per ml; progressively motile < 31%) ” should be corrected to “As one of the male infertility factors, oligoasthenozoospermia is defined as the total number or concentration of spermatozoa and percentage of progressively motile spermatozoa, below the lower reference limits (total number < 39 × 10⁶ per ejaculate; concentration < 15 × 10⁶ per ml; progressively motile < 32%).”

The 5th centiles were used by mistake.
