# Following in the footsteps of E. coli: sperm in microfluidic "strictures"

## TL;DR

This paper compares sperm motion experiments in microfluidic structures to similar studies on E. coli, highlighting hydrodynamic similarities and suggesting that prior bacterial research can inform understanding of sperm migration.

## Contribution

It identifies hydrodynamic parallels between sperm and E. coli experiments and proposes leveraging bacterial motion insights to better understand sperm migration in microfluidic environments.

## Key findings

- Hydrodynamic similarities between sperm and E. coli motion
- Potential for bacterial studies to inform sperm migration understanding
- Comparison of experimental setups and results

## Abstract

We briefly describe the similarities of the experiments of sperm motion in microfluidic "strictures" by Zafeeani et al. in 2019 (Sci. 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.
