egg-cells

Let us note in passing how similar this is to the production of new egg-cells in a _Hydra_, when the mature germs of an earlier generation are prepared and discharged.

The Doctrine of Evolution Its Basis and Its Scope Henry Edward Crampton

In this case germ-cells which otherwise appear and are formed exactly like egg-cells, become capable of developing themselves into new individuals without requiring the fructifying seed.

The Story of Atlantis and the Lost Lemuria W. Scott-Elliot

Parthenogenesis: reproduction by direct growth of germs from egg-cells without fertilization by the male element: as in plant lice, gall wasps, etc.

Applied Eugenics Paul Popenoe 1933

Ideally, menstruation, and with it the ripening of the ova (egg-cells), does not occur while the breasts are active; but when the infant does not suckle, the ovaries regularly resume their function in a very short time.

The Prospective Mother, a Handbook for Women During Pregnancy 1912

Other pertinent clinical facts also lend weight to the opinion that the activity of the breasts, more technically called lactation, should not only prevent menstruation but also hinder the ripening of egg-cells in the ovary.

The Prospective Mother, a Handbook for Women During Pregnancy 1912

The ova or egg-cells are developed in the ovaries, and through a complex and elaborate process a single cell comes to maturity from time to time.

Men Women and God Arthur Herbert Gray 1912

This is asexual reproduction, which means that the multiplication takes place by dividing into two or many portions, and not by liberating egg-cells and sperm-cells.
