nocturnal emission

The nocturnal emission is not a universal method of emptying the seminal vesicles.

These emissions are likely to occur once in two to four weeks and take the place of the nocturnal emission.

I have not had a nocturnal emission for over three years, and probably not more than twenty-five in my life.

This will show that the loss of fluid involved in a nocturnal emission is different from the loss caused by masturbation.
