Age does not influence the development of the blastocyst. In this study, the rate of development of blastocysts in embryos was evaluated on day 3 of culture had an appropriate degree and rate of cell division and it was observed if maternal age modified the effect produced by fragmentation of the embryos in blastulation. According to the results obtained, it is observed that there is a significant negative correlation between the degree of fragmentation of the embryo and the rate of blastocyst development, but age does not exert an effect on the degree of fragmentation or modify the negative effect of fragmentation of embryos on the formation of the blastocyst.

The Immunological Pregnancy Test (GIT) is a simple pregnancy test that is routinely performed on patients who undergo an in vitro fertilization (IVF) procedure approximately 12-14 days after the embryo transfer. Below you have an index with all the points that we will discuss in this article. Index 1. Know if I am pregnant 2. Give the result of the pregnancy test 3. Authors and collaborators The objective of this test is to detect the hormone beta-hCG ( human chorionic gonadotropin ) known as the pregnancy hormone. Pregnancy test or TIG We can measure this hormone in both urine and blood, so for the pregnancy test it will simply be necessary to obtain a urine sample, preferably the first of the morning, or perform a blood draw of the patient. The determination in blood is more objective and allows the exact quantification of the hormone level. However, with the exception of certain specific cases, in FIVValencia we usually perform the urine test because it is easier a...

The third week of gestation corresponds to the third week after the date of the last rule (FUR). Normally, the woman does not yet know that she is pregnant and pregnancy tests can still lead to false negatives. Actually, this third week of pregnancy would be the first of embryonic development. However, all professionals in the sector take as a reference the beginning of the menstrual cycle to start counting the weeks of pregnancy in a gestation of 40 weeks. It is what is known as gestational age. Therefore, during this three pregnancy week, the events that take place are the fertilization and the beginning of the development of the embryo.

Within the world of reproductive biology, there are words that lead to confusion in the future parents, especially in those who face fertility treatment. At this time, everything is new to them and they must face a multitude of explanations from the specialists. This is the case of the words zygote, embryo and fetus. All refer to the future baby during the prenatal stage. However, the difference is found in the different stages of development through which the baby passes during the 9 months of pregnancy. It is very common to confuse these 3 concepts if you do not have basic knowledge of reproduction. Therefore, it is important to know their meaning and know how to distinguish them. Below you have an index with all the points that we will discuss in this article. Index The differences between 'zygote', 'embryo' and 'fetus' during pregnancy 1. Zygote formation 2.

Assisted hatching, also called assisted hatching in English, is a complementary technique that can be done to embryos in culture during an in vitro fertilization (IVF) treatment. It consists of making a small hole in the zona pellucida of the embryo in order to facilitate the exit of the expanded blastocyst, a phenomenon known as hatching, and thus improve implantation rates. Assisted hatching is not routinely used in assisted reproduction laboratories, but it is indicated in some cases of frozen embryos before their transfer.

Embryo transfer is a simple and painless procedure consisting of the deposition of the embryo or embryos in the uterus of the future mother after undergoing in vitro fertilization (IVF) treatment. This is done through a transfer cannula that is inserted through the vagina into ultrasound-guided vision. Next you have an index with all the points that we are going to treat in this article.

Embryo transfer is the final stage of the in vitro fertilization (IVF) process. If fertility treatment is successful, a positive pregnancy test 15 days later will confirm that pregnancy has finally been achieved. The choice of embryo transfer day depends on the evolution of the entire IVF process in general. The specialist is in charge of determining if there are more advantages to transfer in day 3 or day 5 of embryonic development. Currently, the tendency is to transfer a single embryo in the blastocyst stage in order to avoid multiple pregnancies. This is on the fifth day of embryonic development and the probability of implantation is higher. Next you have an index with all the points that we are going to treat in this article.
