High complexity assisted reproduction techniques are adapted to the particular diagnosis of each couple, but the main techniques and procedures we use at IECH are the following:
It consists in putting more than 100,000 sperm in contact with the egg so that fertilization takes place. In this technique, widely qualified biologists use advanced infrastructure to join the egg with the sperm and form an embryo in the laboratory.
Intracytoplasmic Sperm Injection (ICSI)
This is a method in which a single sperm cell is injected into each egg through microinjection. Sperm selection is performed through a 400x enlargement.
This in vitro fertilization technique is used for most cases, particularly the following:
- Women over 40
- Sperm disorders (low sperm count, low motility, or abnormalities in normal forms)
- Failures in previous cycles of in vitro fertilization
- Other egg alterations
This is an innovative incubator that contains a camera capable of capturing images of embryos in time intervals, which makes it possible to monitor embryonic development without removing embryos from the incubator. The large amount of information this system offers allows us to select with greater accuracy the embryos that will be transferred to the uterus, thus increasing the chances of pregnancy.
Each embryo has an individual space. In other words, it does not share the culture medium with other embryos. Since there are no variations in culture conditions, embryos obtained through this process are of better quality and, as a result, pregnancy is more likely.
Blastocyst Embryo Culture
In this method, embryos are cultured in the laboratory until the fifth day of development. To successfully carry out the culture of the embryo up until the blastocyst stage, there are three main requirements: a state-of-the-art laboratory, excellent infrastructure, and a team of qualified biologists with experience who make sure that embryos develop without any difficulties.
Although blastocyst culture gives us fewer embryos to freeze, they will be of higher quality. The survival rate of frozen embryos in the blastocyst stage is very high, which greatly increases chances of pregnancy.
This is an ultrafast freezing technique in which the eggs or embryos are immersed in liquid nitrogen at -196˚C. This allows avoiding cellular damage, thus increasing the survival rate during defrosting. At IECH, freezing is always carried out using the vitrification technique, since it is currently one of the most effective procedures. Vitrification has made the freezing of eggs and embryos in the blastocyst stage possible and has proved to deliver good results.
Sperm Selection Techniques
These techniques are used before choosing the sperm that will be used to perform ICSI. The selection process makes it possible to obtain a sperm with a greater capacity to fertilize the egg. This feature is mainly identified through sperm alterations.
The coordinator of the IECH gamete laboratory is a pioneer in assisted reproduction treatments in Mexico and has more than 30 years’ experience in gamete management. He contributed to the first birth in Mexico achieved through in vitro fertilization, which took place at IECH.
Our embryology laboratory is accredited by the Latin American Network of Assisted Reproduction (LARA Network). Moreover, IECH is licensed by the Mexican Ministry of Health to perform these procedures. Both the accreditation and the sanitary license stand for the superior quality, experience, and professionalism that characterize us and make us proud.
