A. A vasectomy usually takes about 30 minutes, and can be done under local or general anaesthetic. Men usually report feeling a mild to moderate ache in their testicles for a few seconds during the procedure. For a few days after the vasectomy the testicles may ache or feel like they have been kicked.
The right and left lung are not symmetrical, since your right lung has three lobes and your left lung has two. The lobes on both sides of your lungs are separated by fissures. The oblique fissure separates the largest lobe, the left upper lobe, or superior lobe, from the one below it. The lower is called the left lower, or inferior, lobe.
The right lung has three lobes because it does not have to make as much room for the heart. The left lung has two lobes because the heart is found just left of center in the chest.
