Vedclass · Answer

(A) Spermatogenesis,the process of sperm formation,requires a temperature that is $2 - 2.5^{\circ}C$ lower than the normal internal body temperature.If the testes fail to descend into the scrotum (a condition known as cryptorchidism),they remain inside the abdominal cavity where the temperature is too high for effective spermatogenesis.Consequently,this leads to the production of non-viable sperm or a complete lack of sperm production,resulting in sterility in men.Therefore,both the Assertion and the Reason are correct,and the Reason provides the correct explanation for the Assertion.

$A$: Failure of testes to descend into the scrotum causes sterility in man. $R$: Higher internal body temperature is not suitable for sperm development.
