Sanders, L. (2010). Pore propulsion helps out sperm. Science News, 177(5), 12.
The article discusses a study in the February 5, 2010 issue of "Cell" which finds that human sperm relies on an ion channel to reach an unfertilized egg. Also noted in the study was the discovery of a compound similar to one found in marijuana that may interfere with the ion channel suggesting a molecular link between male infertility and habitual marijuana use. An overview of the research, including a discussion on the proton channel Hv1 used by human spermatozoa, is presented.
