Spermatogenesis is a highly regulated, multistage biological process that transforms diploid spermatogonia into mature haploid spermatozoa. This process occurs within the seminiferous tubules of the testes and involves mitotic proliferation, meiotic division, and cellular differentiation known as spermiogenesis.
Sertoli cells provide structural support, nutritional regulation, and immunological protection to developing germ cells. Leydig cells, under stimulation from luteinizing hormone (LH), produce testosterone, which is essential for maintaining the spermatogenic environment.
At the molecular level, transcription factors, epigenetic modifications, and paracrine signaling mechanisms coordinate germ cell maturation. Disruption of these pathways due to genetic mutations, environmental toxins, or endocrine disorders can impair fertility.
