The etymological origin of ovule leads us to ovŭlum, the diminutive of ovum (which can be translated as "egg" ). An egg is a female sex cell that is generated in the ovaries .

It's about a female type gamete which is shaped like a sphere and is susceptible to fertilization by the male gamete, called spermatozoon . When the egg is fertilized, the zygote which, from its development, will become a embryo , then in a fetus and finally in a new creature.

The eggs are cells haploids that carry genetic information. They are produced by ovogenesis in the ovaries, through cell reproduction called meiosis .

In the case of Humans , the women an egg matures every twenty-eight days since they reach the puberty . When this process is performed, the egg leaves the ovary and reaches the fallopian tubes under the process known as menstruation , which includes vaginal bleeding. Menstruation is interrupted when fertilization takes place and the woman, therefore, becomes pregnant.

In addition to all of the above, it is also necessary to establish the structure of the ovule. This is composed of the following parts:
• Nucleus, which is responsible for containing what is the maternal genome.
• Vitelline membrane, includes the so-called glycoproteins that are fundamental elements so that what is the union of the different sex cells can be produced.
• Cytoplasmic membrane, which becomes a key when the ion exchange can occur.

Various are the diseases and disorders that, in one way or another, affect the ovules. Specifically, these include the following:
• Anovulation. A "revolution" of hormones are what cause this pathology, which is, as its name suggests, an alteration in the ovulation process. Among the causes that cause it are stress, excess physical exercise, weight loss ...
• Fibromas. The obstruction of the fallopian tubes as well as the impossibility of having the egg fertilized are some of the consequences that these fibroids bring with them. Specifically, these are growths outside of all normality of what is the muscular tissue that is located in the area of ​​the uterus.
• Polycystic ovary syndrome. Difficulties to stay in state, excessive hair growth or a noticeable weight gain are some of the symptoms that identify this problem. It basically consists of the woman having several cysts in the ovary.

Within the scope of the botany An egg is an organ that is part of the plants . Vegetables also have ovaries: inside, spherical shaped bodies that are created are called ovules, which house female gametes (oospheres ) and other cells.

There are different kinds of ovules in plants, such as campyotropes (with curved shape), the orthotropes (straight) and the anthropotics (elongated).
