Alcohol reduces contraceptive effect OK.

And it would be desirable to specify still, whether the quantity or amount of alcohol influences? And what percent or interest of contraceptive effect is saved? And easier speaking, what percent or interest of probability of pregnancy, provided that ispozuetsja the interrupted sexual certificate or act. Thanks.

On background OK the interrupted coitus certainly will not end pregnancy. But, the more alcohol, the effect OK there is less.
