Spermatogenesis is the process of sperm cell development and maturation. It occurs in the seminiferous tubules of the testes. Within the seminiferous tubules, sperm precursor cells undergo multiple rounds of cell division and differentiation to form mature sperm cells.

Fertilization, the fusion of a sperm and an egg, typically occurs in the fallopian tubes. After ovulation, the released egg travels through the fallopian tubes, where it may encounter sperm and undergo fertilization. The fertilized egg then continues its journey to the uterus for implantation.
