Talk:Sperm motility

Merge

I think this article should be merged to its section in semen analysis. That section is already more detailed than this whole article. Better read this in its context, e.g. with sperm volume or density, since they all contribute to the quality. This deserves inclusion (talk) 19:16, 8 August 2008 (UTC)

This is not a good idea, because this article has nice explanations about the biological basis for motility, such as the explanations of the activation of motility by ATPase and so on. That content would not be appropriate on the semen analysis page, which as i checked is very big but does not have anything interesting to say about motility per se.

Shettles

It would be nice to add here a section discussing Shettles theory of Y sperm swimming faster than X, and make it clear that this theory dating from 1960 could not be confirmed, and in fact is wrong. Many people and websites still propagate this as a fact, and it would be useful to have a section about it here. See for example this paper: Entrenched misinformation about X and Y sperm, Valerie J Grant, http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1440662/

...Reading Shettles's reports in Nature and other peer reviewed journals, many researchers thereafter believed that Y sperm swim faster than X sperm. The finding particularly influenced research on sperm separation. Although several attempts have been made to correct this impression, it was not until the development of computer assisted sperm analysis (CASA) that reliable observations could be made. So far, researchers have found no morphological differences between human X sperm and Y sperm. Neither mature sperm nor their precursors possess significant morphological differences between X and Y genotypes; and Y bull sperm do not swim faster than X sperm.
