An ovum is a female sex cell, circular in shape, of great size, and without any mobility, produced in the ovaries, which mature approximately every twenty-eight days, from puberty, when the ovum leaves the ovary and goes to the Fallopian tube; This whole process is called the menstrual period. Etymologically the word ovule comes from the Latin "ovŭlum" which is the diminutive of "ovum" which means "egg".
The human ovum is created in the ovaries, which are female sexual organs, they are located in the pelvic cavity below the kidneys; formed by a protoplasmic membrane or vitelline, protoplasm or yolk, and nucleus or germinative vesicle. These ovules originate from a process called oogenesis that modifies the cells of the ovaries so that they are later able to fertilize; When the ovum is mature, it travels to the fallopian tubes, as mentioned before, where it may or may not be fertilized by a sperm; If so, the embryo will settle in the uterus and continue a development process for approximately 40 weeks, until the birth of a new being.
In botany, the organ or cell with the appearance of a bag inside the flower is called an ovule, specifically in the ovary, where the oosphere or macrogamete is produced, which when fertilized becomes the seed. On the other hand , an ovum is known as the medicine or drug that is introduced into the vagina, with the fingers or with an applicator, this drug is almost always made from solid vegetable oil that contains the active principle, this is released in a progressive in the vagina as the ovum melts.
