Table 2 Correlation coefficients between age and different PLCζ patterns in fertile controls, in infertile patients, and without separating these two groups (overall).

From: Does advancing male age influence the expression levels and localisation patterns of phospholipase C zeta (PLCζ) in human sperm?

  1. No significant correlations were observed in any of the cases evaluated. [Specific localisation patterns of PLCζ are referred to as: A = acrosomal; E = equatorial; None = absence of PLCζ; PA = post-acrosomal. ‘None’ refers to sperm that were completely devoid of PLCζ].
