The reasons are the same as the causes of incontinence and movement of semen; sometimes the seed moves only during sleep, especially if you sleep on your back, for reasons we already know. They treat it in the same way; tying lead plates to the back has a significant effect, but only sometimes it harms the kidneys, and this should also be monitored. Laying down cooling bedding and sleeping on a bed of willow and similar plants also helps.
Scarcity of seed and output in the form of threads
The reasons for this are the opposite of the reasons for excessive ejaculation, and this often happens in people who have to get tired and do a lot of physical work. It is treated in the same way as weakness of sexual ability is treated, and when the seed comes out in the form of threads, it is treated with moisturizers.
