assertion : spermatogenesis starts at the age of puberty.
reason: secretion of epididymis,vas defernes, seminal vessicle, and prostate gland are essential for maturation and motility of sperms.
give reason why
both assertion and reason are true but reason is not the correct explanation of the assertion . ?

  Assertion is true because spermatogensis start after puberty under the influence of GONADOTROPHIN HORMONES ICSH AND LH WHICH STIMULATE THE SYNTHESIS AND SECRETION OF ANDROGENS AND OTHER FACTORS ESSENTIAL FOR SPERMATOGENSIS
​
Reason is true because all the glandular and epidydmial secretions play role in maturation of sperms;but these secretions do not have a significant role in intiation of spermatogensis;
THUS THE ASSERTION AND REASON BOTH ARE TRUE BUT REASON IS NOT CORRECT EXPLANATION.
