उत्तर
The testes grow in the abdominal cavity near the kidneys and migrate to the scrotum shortly before or during birth. Sperm growth is optimum at temperatures slightly lower than 37°C, which is the usual body temperature. The scrotum lacks adipose insulation, keeping the testes at a lower temperature than the torso. The testes maintain a suitable temperature through involuntary movements of the muscles connecting the scrotum to the body wall.
