Four. One primary spermatocyte (2N) undergoes and completes meiosis I (reductional division to decrease the number of 'chromosomes' received by each daughter cell)and produces two daughter cells, each of which is called a secondary spermatocyte.
A secondary spermatocyte (N) then undergoes meiosis II (equational division for each daughter cell to receive the same number of "sister chromatids", each of which is now considered as a chromosome) and produces two daughter cells called spermatids (N).
These spermatids undergo spermiogenesis (process in which they grow a tail from the centrosome, a midpiece containing several mitochondria to power its swim inside the oviduct come fertilization, and head, which contains the acrosome and the nucleus containing the haploid set of chromosomes) to each become sperm (N).

4 sperms.
A primary spermatocyte divides 2 cells by 1st meiosis.
Each cells (secondary spermatocyte) divides 2 sprematids by 2nd meiosis, then metamorphoses each sperm.
