Assisted reproductive technology

Couples who start assisted reproduction treatment often have doubts about whether the sexual routine can affect the treatment. In most cases, these couples interrupt their sexual relations after the embryo transfer , because they are afraid of losing the embryos due to uterine contractions after orgasm or because of the pressure of the penis against the cervix. Below you have an index with all the points that we will discuss in this article. Index 1. What do professionals say? 2. Results of clinical studies 3. What factors contribute to this success? 4. Authors and collaborators What do professionals say? There is a wide variety of opinions among specialists in assisted reproduction about whether sexual intercourse has advantages or disadvantages with the result of a fertility treatment. Some recommend sexual abstinence before follicular puncture or embryo transfer. The reason for this is the possible rupture of the ovarian follicles after ovarian stimulation, which ca...

The embryo transfer , that is, the introduction of the embryos created in the laboratory in the uterus of the woman, is a simple and painless process that does not require anesthesia. After doing it, the woman remains lying down for 15-30 minutes in the clinic before continuing with her normal life. Between 12 and 15 days after the transfer, the pregnancy test is performed. These days of waiting are full of tension and fears, and the woman tries to follow to the letter the doctor's instructions to avoid making mistakes that compromise the implantation of the embryos.

Can I do something to favor implantation? 4. Authors and collaborators Do we have to do absolute rest? The belief that once the transfer of the embryos has been made, it is necessary to do absolute rest in bed, which implies to paralyze th...

The endometrium is the mucous layer of the uterus in which the embryo adheres, forms the gestational sac and thus gives rise to the beginning of pregnancy. For this to happen, the endometrium must be receptive, that is, have the optimal conditions for embryo implantation. There is hormonal medication that allows an adequate endometrial development that facilitates pregnancy in assisted reproduction patients. However, there are some tips that all women could follow in their day to day to strengthen the endometrium before pregnancy.

In recent years, long cultivation in in vitro fertilization (IVF) treatments has gained special relevance because better implantation rates are obtained with blastocyst transfers (day 5-6 of development) than with embryos in earlier stages. . One of the main advantages is that it allows to improve the embryonic selection. To do this, the blastocysts are classified according to their morphological quality and their degree of expansion, that is, at what stage of development they are: early, cavitated, expanded, hatched, etc. Below you have an index with all the points that we will discuss in this article. What is long blastocyst culture? The long embryo culture consists of keeping the embryos in the laboratory until the 5th or 6th day of their development, when they reach the blastocyst stage. In the blastocysts we can clearly differentiate two structures, that is, it is possible to distinguish: Trofoectodermoson the blastocyst cells that come in contact with the endometrium and, ...

The techniques of assisted reproduction are a series of treatments aimed at artificially helping to produce the fertilization of the oocyte by the sperm and the subsequent implantation of the embryo and thus achieve the desired pregnancy. Let's see the Intrathoracic Transfer of Cigotos (TIC) below. Below you have an index with all the points that we will discuss in this article.

One of the stages of in vitro fertilization treatments (IVF) is the evaluation of embryo quality in the laboratory. Not all the embryos generated are apt to transfer or vitrify, since their viability may be compromised. Therefore, it is necessary to follow morphological criteria that help specialists in the choice of embryos of optimum quality. The main purpose of the embryo selection is to identify the embryo with the greatest possible implantation capacity to be transferred to the uterus of the future mother.

The endometrial receptivity test, also known as the ERA Test or ERA Test, is a molecular diagnostic test used to determine the state of receptivity of the endometrium. Thanks to this test, implantation failures are less likely to occur since it allows us to determine the most appropriate day to carry out the embryo transfer.
