Maternal age
downin G. aculeatus1
Maternal age decreases sperm telomere length in G. aculeatus.
“sons (F1 males) of old mothers had a smaller adult body size and produced sperm with shorter TL than those of younger mothers.”

Chromatin decondensation
downin dogs1
Sperm telomere length is associated with chromatin decondensation in dogs (rs = -0.71, P < 0.01).
“and negatively correlated with semen chromatin decondensation (P < 0.01; rs = -0.71)”

Semen volume

Sperm telomere length is associated with semen volume in dogs (rs = 0.63, P < 0.05).
“STL was also positively correlated with semen volume (P < 0.05; rs = 0.63)”

Age
downin dogs1
Age is associated with sperm telomere length in dogs (rs = -0.68, P < 0.001).
“Both LTL and STL were also negatively correlated with age (P < 0.05 and rs = -0.50; P < 0.001 and rs = -0.68).”
