TL;DR: The late 20th century trend to delay birth of the first child until the age at which female fecundity or reproductive capacity is lower has increased the incidence of age-related infertility and stimulated interest in the possible factors in the female and the male that may contribute to the decline in fecundities with age.

TL;DR: Reducing the multiple gestation pregnancy reproductive treatment treatment cycles because of the perceived need rate should be a high priority for assisted reproductive to stimulate excess follicles and transfer excess embryos in treatment programmes, despite the pressure from some order to achieve reasonable pregnancy rates.

TL;DR: It is suggested that Ca2+ is required for functional changes in bull sperm, with aCa2+‐ATPase modulating intracellular Ca2 + during capacitation and calcium channels controlling the Ca2- influx required for acrosomal exocytosis.

TL;DR: In this article, the substrate requirements for capacitation of mouse spermatozoa, initiation of the acrosome reaction and support of fertilization of mouse eggs in vitro were examined by assessing not only fertilization rates, but also the stages of egg activation and sperm head decondensation in fertilized eggs to monitor the temporal aspects of these processes.

TL;DR: This study provides the first evidence that E(2) and environmental estrogens can significantly stimulate mammalian sperm capacitation, acrosome reactions and fertilizing ability, with the environmental estrogen being much more potent than E( 2).
