Frequency of nocturnal emission

I have not ejaculated voluntarily for the past 1 year, but involuntary ejaculations were still common. I did proper yoga in order to reduce the frequency of nocturnal emissions. Earlier I used to involuntary ejaculate once in 15 days, but in the last week itself I have had 2 nocturnal emissions. I just want to know whether the frequency of nocturnal emissions is normal or might it be spermatorhoea? Thank You.
