Hey there!
Here's the answer you are looking for
Spermatids are formed after spermatogonia undergoes meiosis in the process of spermatogenesis.
Meiosis is a process of cell division in which 4 halploid cells are produced from 1 diploid cell. And meiosis only occurs in diploid cells.
Spermatogonia, present in seminiferous tubules of testis of male reproductive organ, is diploid. And in order to form sperms, it has to under go division.
So, SPERMATOGONIA, at puberty, undergoes mitosis first, to form 2 PRIMARY SPERMATOCYTES, which are diploid (cause they are formed after mitosis).
Each PRIMARY SPERMATOCYTE then under go 1st meiostic division to form 2 haploid SECONDARY SPERMATOCYTES.
Each SECONDARY SPERMATOCYTE then undergoes 2nd meiotic division to form 2 haploid SPERMATIDS.
Then, each of these SPERMATIDS undergo differentiation to form haploid sperms.
