- BTo help in respiration
- CTo help in maintaining the normal internal body temperature
- DTo help in maintaining the low temperature necessary for spermatogenesis
Correct answer
D. To help in maintaining the low temperature necessary for spermatogenesis
Step-by-step solution
The testes are situated outside the abdominal cavity within a pouch called scrotum. The scrotum helps in maintaining the low temperature of the testes (2–2.5o C lower than the normal internal body temperature) necessary for spermatogenesis. In adults, each testis is oval in shape, with a length of about 4 to 5 cm and a width of about 2 to 3 cm. The testis is covered by a dense covering. Each testis has about 250 compartments called testicular lobules
