Sperm guidance is the process by which sperm cells (spermatozoa) are directed to the oocyte (egg) for the aim of fertilization. In the case of marine invertebrates the guidance is done by chemotaxis. In the case of mammals, it appears to be done by both chemotaxis and thermotaxis.

Famous quotes containing the word guidance:
“If Los Angeles has been called “the capital of crackpots” and “the metropolis of isms,” the native Angeleno can not fairly attribute all of the city’s idiosyncrasies to the newcomer—at least not so long as he consults the crystal ball for guidance in his business dealings and his wife goes shopping downtown in beach pajamas.”
