title: No evidence of the existence of beta adrenoceptors in human sperm using radioligand binding technique.
abstract: The investigations were carried out on 20 freshly ejaculated and pooled samples of human semen with normozoospermia and motility of 70-80%. In the present study no difference was found between total and non-specific binding to semen membranes using [3H]-dihydroalprenolol (DHA) as a radioligand. Our results suggest that beta adrenoceptors could not be found in human sperm.
