It often does not include the short-lived spermatocyte, spermatid, or sperm cells.

The primary spermatocyte is initially diploid and undergoes meiosis.
From the en.wikipedia.org
Each primary spermatocyte duplicates its DNA and subsequently undergoes meiosis I to produce two haploid secondary spermatocytes.
From the en.wikipedia.org
As a result of meiosis, each spermatid contains only half of the genetic material present in the original primary spermatocyte.

Asymmetric spermatocyte cell division likely results in the much greater number of females seen in some worm species in comparison to males.
From the nature.com
Each primary spermatocyte divides into two secondary spermatocytes, and each secondary spermatocyte into two spermatids or young spermatozoa.
From the en.wikipedia.org
A spermatocyte is a malegametocyte, derived from a spermatogonium, which is in the developmental stage of spermatogenesis during which meiosis occurs.
From the en.wikipedia.org
Thus, the primary spermatocyte gives rise to two cells, the secondary spermatocytes, and the two secondary spermatocytes by their subdivision produce four spermatozoa.
