文摘
- •
For the first time [Na+]i has been quantified in the spermatozoa of a marine fish before and after motility activation.
- •
The [Na+]i levels in European eel sperm only increase after hyperosmotic activation in a medium containing sodium.
- •
Sperm motility activation is accompanied by a significant reduction in sperm head area.
- •
Na+ removal from the seminal plasma caused a strong reduction in sperm motility and reduced the sperm head area.
- •
An amiloride-sensitive sodium channel is involved in European eel sperm motility.
