It also is the job of the epididymis to bring the sperm to maturity, since the sperm that emerge from the testes are immature and incapable of fertilization. The germination phase represents the second phase of growth in the male gametophyte, consisting of three cells. Female gametophyte is the female gamete-producing structure, which comes from the megaspore. Megasporangium produces the megaspores inside the ovary in angiosperms. After sperm is created in the seminiferous tubules, sperm cells travel toward the epididymis through the rete testis. 1. In women, this is marked by changes in hormone production.
