Method Spermatozoon surface area was measured by micrometric methods and was also measured from electron micrographs using a stereological method. Micrometric methods gave surface area above. Stereology methods gave surface area of 142µm^2. Sperm volumes were estimated by stereology and by radiolabel volume exclusion methods. Stereology measurement gave volume above.
Comments From the volume exclusion method, ram sperm volume was estimated as 25µm^3.
