Final answer:

A normal human primary spermatocyte contains 44 autosomes, which corresponds to 22 pairs of autosomes before the first meiotic division.

Step-by-step explanation:

A normal human primary spermatocyte contains 44 autosomes. During spermatogenesis, a primary spermatocyte is a diploid cell, which means it has two sets of chromosomes: one set from the mother and one set from the father. Since humans have 22 pairs of autosomes, a primary spermatocyte, having the full diploid number before meiosis, will contain 22 pairs of autosomes, or 44 autosomes in total. This is because it has not yet undergone the reduction division that characterizes the first stage of meiosis, which halves the chromosome number.
