Semen parameters and capacitation

A relationship exists between several semen parameters and the ability of spermatozoa to capacitate. The increase of oligoteratozoospermia, which could be related to testicular dysfunction, is correlated with the decrease of the percentage of spermatozoa able to "capacitate". The increase of loss of motility with time, which could be related to abnormalities of the seminal fluid, is also correlated with a decreased number of spermatozoa able to "capacitate".
