The germ cells progress first from the diploid to haploid state and then change shape to become spermatozoa. The process of spermatogenesis then allows the recombination of male and female haploid gametes at fertilization. This provides genetic contributions from both parents without increasing the number of chromosomes each generation.
Spermatogenesis occurs in medullary sex cords known as seminiferous tubules.
Seminiferous tubules are part of the male gonad or testes. Cells involved in spermatogenesis. Environment for germ cells to develop and mature iii. Substances initiating meiosis or the reduction from diploid to haploid cells iv. Adluminal compartment is c.
