Mammalian Sperm Guidance — An Overview
Pp. 265-271 (7)
In the recent two decades mammalian spermatozoa were demonstrated to
perform chemotaxis, thermotaxis and rheotaxis. It is believed that in the Fallopian tube
spermatozoa are first guided to the fertilization site by long-range mechanisms,
thermotaxis and rheotaxis, and there they are guided to the egg by two processes of
chemotaxis, considered a short-range mechanism. The occurrence of chemotaxis and
thermotaxis in additional locations along the female genital tract cannot be excluded.
