How many spermatozoa are formed from one secondary spermatocyte ?
A primary spermatocytes completes the first meiotic division (reduction division) leading to formation of two equal haploid cells called secondary spermatocytes (each has $\mathrm{n}=23$ chromosomes). The secondary spermatocytes undergo the second meiotic division to produce four equal haploid spermatids.
