Which of the following statements about spermatogenesis is NOT true?

A) Each spermatic forms two sperm.
B) The secondary spermatocytes form two spermatids.
C) The spermatogonium forms the primary spermatocyte.
D) The primary spermatocyte forms two secondary spermatocytes.

Each primary spermatocyte forms two secondary spermatocytes, and each secondary spermatocyte forms two spermatids, which then differentiate into spermatozoa. However, each spermatogonium divides mitotically to give rise to two identical daughter cells, one of which remains a spermatogonium and the other differentiates into a primary spermatocyte. Therefore, statement A is not true.
