Options
- ATo store sperms
- BTo provide nutrition to germ cells
- CTo maintain the low temperature necessary for spermatogenesis
- DTo facilitate insemination
Correct answer
C. To maintain 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
