Where to the sperms go when tubes are blocked off?
They will be going back by re-absorption to your body, which around 1 sperm in 2 would have done anyway without the sterilization. After the sperms are manufactured by the testicles, they travel from there and to the epididymus in where they are kept in storage for up to 30 days. In here, there is liquid flowing all the time through membranes going back into your body and any solid content left here will be “eaten” by macrophage cells. Following a vesectomy, this machinery will simply use more of the stored sperms.
