The ivum is the centrally located nucleus of the female egg. It contains most of the female’s genetic material and is fertilized by sperm. The ivum degenerates if it is not fertilized. Its most important function is to produce an embryo.
It contains most of the female’s genetic material
An Ivum is the cell that contains most of a female’s genetic material. An egg cell consists of an Ivum, an egg cell that is produced by a female and released every 28 days. The egg travels through the fallopian tube and into the uterus where it sheds with the uterine lining every month. The lining has a good blood supply that would help the embryo develop.
It is fertilised by sperm
Sperm fertilize an Ivum through a complex process. The sperm float up to the Ivum, swim around it, and adhere to the oocyte. After they adhere, they rotate about the ivum’s longitudinal axis.
In fertilisation, hundreds of sperm surround the egg. They each have a specific goal, and have to penetrate the egg membrane in order to get to its cytoplasm. The sperm then releases its genetic contribution into the cytoplasm of the egg, where it will fuse with the egg’s chromosomes.
The sperm is shaped like a cone, with two parts: a head and a tail. The head is made up of a small nucleus surrounded by a cell plasma known as the yolk. The nucleus contains the genetic material that will be inherited by the child.
Sperm can also encircle the womb directly, bypassing the cervix, which weeds out sperm that are physically abnormal. Typically, about 20 million sperm are found in the womb, which is less than a tenth of the number in an average ejaculate. However, this is enough to achieve a routine pregnancy rate.
The uterus has three main parts: the ovaries, the fallopian tubes, and the endometrium. The ovaries produce eggs and the main female sex hormones, including LH and GnRH. Each part of the reproductive system has two major functions.
The sperm and egg do not always meet at the same time, which can hinder the fertilization process. The sperm may arrive too early or too late to meet the egg, or the egg may be in the wrong fallopian tube. A woman may even conceive twins instead of a single baby, if her ovaries release two eggs.
It degenerates if not fertilized
During the reproductive process, an unfertilized egg begins to degenerate after about 24 hours. After fertilization, the egg begins a series of cell divisions to produce two fertile eggs. The ovaries of females contain 400,000 primary oocytes each, and if one of them is not fertilized, the egg degenerates.
The corpus luteum, the organ responsible for producing progesterone, stops producing it if the Ivum is not fertilized. During early pregnancy, the corpus luteum continues to function, keeping the uterus and endometrium moist and rich in nutrients. If fertilized, this organ continues to produce progesterone, which helps maintain the pregnancy.
After ovulation, the corpus luteum remains in the ovary. It contains hormones that inhibit the release of FSH and LH. This limits the development of follicles during the second half of the cycle. After 14 days after ovulation, the corpus luteum degenerates, forming a scar. Once this process is complete, the ovary no longer produces progesterone or estrogen.
It produces three tiers of cells
The Ivum is a reproductive organ that contains the genetic material of a woman. This genetic material is carried by the sperm cell and determines the child’s characteristics. There is a nucleus within the Ivum, which is surrounded by a cell plasma known as the yolk. The yolk contains the nutrients needed for the development of the egg cell.
