In biology, the egg, or ovum, is the female gamete, a haploid reproductive cell that, upon fertilization by a sperm, gives rise to a new organism. In many animals the term also denotes the encapsulated structure in which the embryo develops outside the maternal body, comprising the ovum together with stored yolk and protective membranes or shells, as in the amniotic eggs of birds and reptiles. Egg biology spans oogenesis and the maturation of oocytes, fertilization and early embryonic development, and the reproductive strategies of oviparous species, including clutch size, incubation, and the environmental control of development. In reptiles, incubation temperature can influence embryonic growth rate and, in some species, sex determination, while in birds egg quality, microbiology, and incubation shape reproductive success. In human and mammalian reproductive medicine, oocytes are central to fertility, assisted reproduction, and oocyte cryopreservation. Research relevant to this area examines embryo growth rate in relation to incubation temperature in sea turtles, microbial and antimicrobial characterization of avian eggs, oocyte freezing and ovarian stimulation, reproductive parameters of fish populations, and the reproductive biology of wild bird species. The journal publishes peer-reviewed research on Wildlife and reproductive biology, addressing gametes, eggs, embryonic development, and the reproductive strategies of animal species across taxa and environments.
