What is considered a fertilization of a female egg?
Fertilization is a combination of a female egg with a male sperm, as a result of which a zygote appears, reborn into an independent organism.
- In the fundamentally reproduction of a person is fertilization stage, which organizes the transfer from parents, hereditary features to children. Following the fertilization, the transformation of zygote into an embryo.
- Fertilization occurs at the time of ovulation.
Ovulation is an egg output ready for fertilization from the ovarian follicle.
- Clinging to the villi, the egg moves along the uterine pipe towards the uterus, where fertilization occurs. The life of the egg lasts from 12 to 24 hours, and after the expiration of time, she dies. If during this time, the sperm manages to meet with the egg, the conception comes.
- With a 28 -day menstrual cycle, ovulation occurs on the 12th or 14th day. However, it happens that this moment occurs earlier or later than the designated period: early or late ovulation. More accurately calculate the favorable day, you can use an ultrasound of the diagnosis or tests to determine ovulation.
- Women also practice calculations by measuring basal temperature, a sharp increase in the first phase of the cycle shows the expected ovulation day.
There are three types of fertilization: natural fertilization, artificial insemination, as well as IVF.
- If the first option occurs without extraneous intervention, then in the last two, the participation of medicine is required.
- With intra -flash administration - The egg is fertilized inside the woman's body.
- For eco - The egg is removed from the body.
Where is the fertilization of the female egg?
- The fertilization process is accomplished in the expanded part of the fallopian tube, which is located near the ovary - ampular part. To connect to the egg, the sperm passes through the two shells: a radiant crown and a shiny shell.
- At the same time, to destroy the first layer, the participation of other spermatozoa is necessary. After that, the one who is the first to get to the second shell will fertilize the egg. Then, the division begins in the egg, and it moves in the fallopian tubes towards the uterus. This path lasts from 7 to 8 days.
- Having reached the uterus, the egg is attached to its mucous membrane to receive the nutrients necessary for the growth and vital activity of the embryo.
- When the procedure is performed artificial insemination, Some stages inherent in the natural method are missed. The extracted egg at eco - connects to sperm and stored in an incubator-ternotat, There is her division and insemination.
- Such manipulation can be carried out both by the method of insemination and with the help of ICSI - the internal injection of the egg, spermatozoa. For effectiveness, experts extract several eggs at once and prepare them in the incubator. After that, the specialist selects high -quality embryos and moves them into the uterine cavity, expecting further implantation.
- After planting the embryo, the woman is prescribed supporting hormone therapy. It happens that several viable embryos are taking root, and a woman has the right to leave the required amount.
- Embryos that were not involved in implantation are left for Cryo conservation. If you need a repeated procedure for introducing the embryo, they will use them.
- Artificial insemination - Introduction of sperm using a catheter into the fallopian cavity. This is a more similar method with natural fertilization. This method is common among couples who do not have the opportunity to conceive a child in a natural way, or single women. In this case, you can use not only the sperm of the partner, but also the donor sperm.
What is considered the conception of a child?
- Conception - This is the initial stage of pregnancy formation. This process is caused by the beginning of the fertilization of the egg, which then goes into the emergence of a new organism in the womb and leads to pregnancy.
- In fact, conception can be considered - the beginning of the successful introduction of the embryo into the mucous membrane of the uterus. Previously, the blastocyst is freed from his own shell and it is reunited with the endometrium.
Where is the conception of the child?
- After the formation of a stable connection of the egg and sperm into a single nucleus, it is formed zygotewhich over the next day is divided into Two blastomers. Further, each part is divided into half - the rapid development of cells is read.
- Clothing of cells And movement during conception occurs in stages. On the third day the embryo consists of 8 blastomers and acquires a personal genome, capable of leading to the origin of the twins.
- Four days - The movement of the embryo continues to the uterus, along the phallopium pipe. The embryo has Up to 16 cell divisions and compacted. At this time, there is a high risk of ectopic pregnancy with pathologies. Therefore, it is recommended to make an ultrasound.
- Fifth and sixth day - The embryo enters the uterine cavity and makes the first attempts to attach to its wall. Sometimes attachment is noted by the release of a small amount of blood - women often confuse it with the beginning of menstruation.
- Also, this stage is accompanied by the formation of a woman hormone in the blood of a woman, the embryo is fixed and continues its development.
- On the tenth day, a woman can see a positive result - by making pregnancy test.
What is the difference between conception and fertilization?
- It was previously believed that fertilization and conception They mean the same process - the fusion of the egg with a sperm. In modern medicine, it is customary to separate these two terms, despite the fact that they interconnected.
- From a medical point of view, conception is the formation of a woman’s pregnancy, which includes the following stages: fertilization, cell division and attachment of the embryo to the wall of the uterus.
- This term combines all the processes that occur in the early stages of pregnancy - the first 2 weeks from the moment of fertilization to the early signs of pregnancy, an increase in hCG, delayed menstruation, and growth of basal temperature.
- Fertilization - That's only the initial stage of conception. However, in many non -medical sources, these two terms are mistakenly generalized or considered interchangeable.
Conception and fertilization: reviews
Reviews about conception and fertilization:
- Marina, 27 years old. It was interesting to learn about how the sacrament of the origin of human life was happening. The description by days will help to more accurately determine when conception occurred. Still, this is important for the future planning.
- Elena, 30 years old. To determine the day of ovulation, I use the methodology for building a graph of basal temperature. Now, knowing how the embryo is moving through the fallopian tubes, I can assume the exact date of conception.
- Olga, 23 years old. As a future mother, I am interested in everything related to the upcoming pregnancy. I always believed that it makes no sense to conduct an ultrasound in the early stages. It turns out that I was mistaken and diagnosis is not only possible, but also necessary: \u200b\u200bto exclude an ectopic pregnancy.
