examine the impact of cryostorage on the lipid peroxidation levels observed prior to sperm separation. Details of the semen profiles for these additional subjects are also given in Table 1 . As indicated in Supplementary Table 1 (see section on

issues of cross-contaminations in liquid nitrogen ( Bajerski et al. 2021 ), cryo-storage systems are prone to failures – from equipment breakdown to human error – which, recently, has led to dramatic sample losses in human fertility clinics and research
