This study has assessed the effect of zinc on human sperm motility and the acrosome reaction in vitro. Progressively motile human sperm were selected by swim‐up and by glass bead columns and then incubated in a medium in ...

A prospective study was carried out on semen samples from 118 consecutive unselected men attending our infertility clinic to determine whether sperm motility may be affected by seminal plasma. The incidence of asthenozoospermia ...

Sperm maturation, as a process through which spermatozoa acquire the ability for motility activation and fertilization, is well-known for many groups of animals. This process takes place in a taxon-specific manner in ...

Inseminations with frozen-thawed epididymal sperm have resulted in low-pregnancy rates of mares. If fertility of epididymal sperm could be improved, it would help to preserve genetic material from stallions that have ...
