Abstract
The hamster adrenal gland was found to be a new and very potent source of "sperm motility factor" (SMF); the activity of SMF in adrenal extracts was approximately 100 to 200 times that in hamster blood serum. Hamster epididymal spermatozoa incubated with adrenal extracts became capacitated. as shown by their ability to fertilize cumulus-free eggs. Like the SMF in human blood serum, the hamster adrenal SMF has a low molecular weight (about 100 to 200) and is heat-stable.Keywords
