The primary spermatocyte divides meiotically (Meiosis I) into two secondary spermatocytes; each secondary spermatocyte divides into two equal haploid spermatids by Meiosis II. The spermatids are transformed into spermatozoa (sperm) by the process of spermiogenesis.

During which stage are spermatids converted to spermatozoa?

Spermiogenesis is the differentiation stage of spermatids into mature spermatozoa. At this stage, the spermatids go through morphological changes to become more streamlined and compacted.

Where do spermatozoa develop?

Sperm develop in the testicles within a system of tiny tubes called the seminiferous tubules. At birth, these tubules contain simple round cells.
