| The ovary consists of a cortical zone composed of a specialized stroma, which contains follicles with ova. |
| The ovaries perform both an exocrine function by producing ova and an endocrine function by producing estrogen and progesterone. |

| De Graaf, working without the aid of a microscope, made the error of thinking that the fluid-filled follicles were the ova themselves. |
| If X chromosome loss occurs during oogenesis, then some ova are expected to be nullo-X, which would result in a patroclinous non-Unc male. |
| The ova penetrate the intestinal wall and pass through the portal vein to the liver, lung, and other tissues. |
