Adv. 5, eaav21111, 2019) and those by Altshuler et al. in 2013 (Soft Matter 9, 1864, 2013). We shortly discuss the hydrodynamic elements justifying the strong resemblance between the two types of experiments, and suggest that other previous results in E. coli motion (Soft Matter 11, 6248, 2015) may shed further light on the understanding of sperm migration.","authors_text":"A.
