Primary spermatocytes are always diploids

54 * 2 = 108

Explanation:

Primary spermatocytes are diploid (2N), meaning they have a full set of DNA; having a full set of chromosomes. They thus undergo meiosis to form two haploid (N) secondary spermatocytes containing half of the DNA. Therefore, the primary spermatocytes will have 108 chromosomes.
