What is the term used for the female gamete that has completed meiosis?

The term used for the female gamete that has completed meiosis is "ovum." During the process of oogenesis, which is the development of female gametes, primary oocytes undergo meiosis. Upon completing meiosis I, these cells produce secondary oocytes, which may soon complete meiosis II upon fertilization. The final result of this process, assuming fertilization occurs, is the mature ovum, which is capable of being fertilized by sperm, leading to the formation of a zygote.

Ovum refers specifically to the mature egg cell that is capable of being fertilized. This contrasts with terms such as oocyte, which denotes the earlier stages of egg development and not the fully matured gamete. Spermatozoa are the male gametes and pertain to male reproductive cells, while a follicle refers to the ovarian structure that contains and nurtures the developing oocyte before ovulation. Thus, the ovum is the correct designation for the female gamete at the point where it has completed meiosis.
