Viable sperm is obtainable with PSR well after the currently recommended 24-h time interval. PSR should be considered up to 36 h after death, following appropriate evaluation. No correlation was found between cause of death and chance for successful sperm retrieval.
Label-free IPM can identify sperm cell abnormalities, with an excellent correlation with label-based BFM, and with higher accuracy compared with label-free BFM. Further prospective clinical trials are required to enable IPM as part of clinical sperm selection procedures.
EEJ is a safe and feasible procedure for cryopreservation in adolescent cancer patients who are unable to masturbate. The wide diversity of EEJ outcome and ejaculate parameters may represent a continuum of pubertal changes in that population.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
