Few years back i had swollen testicles, doctor said it was may be because i slept i wrong posture or cycling or some sports. anyways after few days it cured, however, my left testicle shrinked to peanut size and other side is normal.. so what could be the reason this happened? I asked my doctor he said its normal .. but its too small like peanut ? so can it somehow grow back to normal like it was before?
