Assisted reproductive technology

Natural pregnancy with teratozoospermia can be complicated and, in the most severe cases, it is practically impossible for fertilization and subsequent development of the embryo to take place. Men with infertility due to teratozoospermia will have to resort to assisted reproduction techniques to be able to be parents. The appropriate fertility treatment will depend on many factors, not just the degree of abnormalities in the sperm. The rest of the seminal parameters, as well as the age and health status of the woman, are also limiting when it comes to getting the pregnant woman.

Prospective study to determine the level of damaged DNA, both oxidized and fragmented, in the sperm used for insemination (IUI)> and sperm microinjection (ICSI), and its impact on the rate of fertilization and clinical pregnancy. The conclusions of this study ensure that oxidative damage to sperm DNA has a negative impact on the clinical pregnancy rate in intrauterine insemination (IUI), but not in intracytoplasmic sperm cycles (ICSI).

Oxidation of sperm DNA (8-OHdG) 4. Conclusions 5. Bibliography 6. Authors and collaborators Sperm DNA To analyze the fragmentation of the sperm DNA, the TUNEL test was used and to study the oxidative stress, the biomarker 8-hydroxy-2'-deoxyguanosine (8-OHdG) was used. The biomarker of oxidative damage in DNA (8-OHdG) was highly correlated wi...

The ICSI is a procedure of assisted reproduction in which the fertilization of the ovules is performed by sperm specially selected for their morphology, so it occurs in the laboratory. After the insemination of the ovules, a follow-up is performed to observe the development of the embryos, based on how the cell divisions are produced, the quality of the embryos is determined. Those embryos of better quality will be chosen to carry out the transfer in women, which is usually done on day 3, although in certain cases the transfer is recommended on day 5. Below you have an index with all the points that we will discuss in this article. Index Rest at ICSI 1. Normal life after transfer 2. Benefits of moderate exercise Embryo transfer is a very simple process, it does not require anesthesia (since it is not a painful intervention) and the duration is 15 minutes maximum. The gynecologist inserts a cannula with the embryos into the vagina and deposits them inside the uterus. It is re...

The ICSI is a technique of assisted reproduction that consists of introducing the sperm that has better characteristics inside the ovule, producing an assisted fertilization. The last step of the ICSI process is the transfer of the embryos. From the ovules that have been fertilized, the evolution of the development of the embryos is observed. The fertility expert must select those embryos that have had a better development and are considered of higher quality to perform the embryo transfer, which can occur on day 3 or day 5. Below you have an index with all the points that we will discuss in this article. Index Expect the result of ICSI 1. Time of waiting 2. When and how to do the pregnancy test Wait time Once the transfer of the embryos in the uterus of the woman has taken place, you should wait for about two weeks to know if the treatment has been successful and the pregnancy has been achieved. Many women call this period the beta wait. It is necessary to wait for this ti...
