文摘
The removal of K+ from the seminal plasma induced a decrease in sperm head area, an increase in pHi and a strong reduction in sperm motility. For the very first time the pHi of eel spermatozoa has been quantified before and after sperm motility activation. The alkalinization of the pHi by the use of NH4Cl, inhibits sperm motility. A 4-AP-sensitive voltage gated potassium channel is involved in European eel sperm motility.
