DOI: 10.1002/advs.201900712
Abstract: Abstract Intracytoplasmic sperm injection is a popular form of in vitro fertilization, where single sperm are selected by a clinician and injected into an egg. Whereas clinicians employ general morphology‐based guidelines to select the healthiest‐looking… read more here.

DOI: 10.1002/ece3.8514
Abstract: Abstract Sperm cells exhibit extraordinary phenotypic variation, both among taxa and within individual species, yet our understanding of the adaptive value of sperm trait variation across multiple contexts is incomplete. For species without the opportunity… read more here.

DOI: 10.1002/em.22530
Abstract: In March 2020, the Italian government imposed a national lockdown which was almost completely removed in June 2020. Due to the abrupt stop of human activities, emissions of air pollutants decreased. Air pollution is an… read more here.

DOI: 10.1002/jcp.26876
Abstract: In previous studies, we described the presence of fibroblast growth factor 2 (FGF‐2) and its receptors (FGFRs) in human testis and sperm, which are involved in spermatogenesis and in motility regulation. The aim of the… read more here.
