Knowing the etymological origin of the term oocyte leads us to analyze what emanates from the Greek. Specifically, it is the result of the sum of two components of that language: "oo", which can be translated as "egg", and "kytos", which is equivalent to "cell".
The oocytes are female germ cells that are generated in the ovaries . It is a phase of the development of Ovum , when it has not yet matured. The oocyte arises as part of the gametogenesis process that develops in the women and in the females of the animals.
The procedure begins with a primordial germ cell that transforms into a oogonium through the meiosis . This oogonium, after the ovogenesis , it will become an oocyte that will eventually result in a mature ovum . He menstrual cycle It causes these ovules to detach from the ovaries every 28 days from puberty to menopause.
The oocyte, which is also called ocito or oocyte It is therefore a female cell that is on its way to becoming a mature ovum. This kind of cells It has a good level of cytoplasm that allows it to contribute to cellular nutrition at the beginning of development.
It is important to note that the amount of oocytes that a woman It is already defined before birth, since it is established in fetal development. Over the years, women will lose eggs in a phenomenon known as atresia . Menstruation causes the oocyte to develop and, in turn, be lost: by reaching 35 years of age, the woman will have about 10% of the ocitos she was born with, a circumstance that makes fertilization more complicated to specify and that the risks of Health In the unborn child.
For this reason, it is established that when an older woman wishes to become pregnant, it is necessary, in most cases, to undergo a gynecological study. Why? Because your ovum reserve capable of shaping a baby in perfect health may have been exhausted.
Thus, if you undergo such an analysis, in a clinic or medical center, it is usual to have a chromosomal study and even a polar corpuscle biopsy.
The result achieved in these tests may determine that it is necessary that the woman in question has to undergo in vitro fertilization if she wants to have a baby. For this, medical professionals before starting the process, will take into account factors such as ovarian reserve and also the relevant ovarian stimulation.
In this way, it is when the doctor who directs the treatment will be able to know what is the most suitable time to carry out fertilization, that is, when there are more guarantees that it will be a success. In this sense, it must also be stated that fertilization can be of two fundamentally types: conventional or intracytoplasmic sperm microinjection. The latter is more complex but offers great results of effectiveness.
