Lactate inhibits glucose‐induced zigzag motility and enhances linear motility in bull spermatozoa by suppressing glycolysis

open access: yesAndrology, EarlyView.
Abstract Background Energy metabolism and substrate balance are critical determinants of sperm motility and fertility. Linear motility is necessary for sperm forward movement, whereas hyperactivated motility is a prerequisite for fertilization. The preference of metabolic pathways depends on substrate availability which controls sperm motility. However,

Animal medical systems from Apis to apes: history, recent advances and future perspectives

open access: yesBiological Reviews, EarlyView.

Consistent and flexible maternal effects: how the environments of a mother influence the offspring phenotype

open access: yesBiological Reviews, EarlyView.
ABSTRACT The environment experienced by a mother influences offspring phenotype through maternal effects, which can have significant adaptive benefits for both the mother and the offspring. However, the ways in which maternal environments influence offspring development are extremely diverse, and empirical studies using an outcome‐based approach often ...
