Question

Temperature of the scrotum which is necessary for the functioning of testis is always around __________ below body temperature.

• A. $2^{o}C$
• B. $4^{o}C$
• C. $6^{o}C$
• D. $8^{o}C$

Answer 1

The correct option is A $2^{o}C$

Scrotal temperature is about 2${}^{o}C$' lower than the rest of the body. This temperature required for the process of sperm development, or spermatogenesis, (the process by which haploid spermatozoa develop from germ cells in the seminiferous tubules of the testis.) to proceed normally.

So, the correct answer is '2${}^{o}C$'.
