Definitions:

Meiosis

A type of cell division that reduces the chromosome number by half, creating four daughter cells, each with half the number of chromosomes of the parent cell, essential for sexual reproduction.

Primary Spermatocytes

Diploid cells that undergo meiosis I to form two haploid secondary spermatocytes, crucial for spermatogenesis.

Spermatogonia

Undifferentiated male germ cells in the testes that divide to produce sperm.

Spermatids

Immature sperm cells that are the product of spermatogenesis, which will undergo further development to become mature spermatozoa.
