In comparison with the general population, there is a greater prevalence of chromosomal abnormalities amongst couples with reproduction issues. An analysis of the 46 chromosomes (23 pairs), DNA structures and highly-organised proteins that contain a living being’s genetic information is known as a karyotype. All that is needed is a simple blood sample so that […]
Use of the intracytoplasmic spermatozoa injection (ICSI) technique began in the 1990s. It has been successfully used to resolve most severe cases of male sterility. Here is some information about when we use the ICSI technique:
When is ICSI (Intracytoplasmic Sperm Injection) indicated?
Oligozoospermia and criptozoospermia: a severe decrease in the number of […]
Embryo implantation is the process in which the human embryo adheres to the endometrium, where it continues developing. The first step of this process begins with the dialogue between the embryonic and maternal cells.
This is an extremely complex process that is currently only partially known and depends on the embryo quality, uterine receptivity and their […]
One of the options for patients undergoing In Vitro Fertilization (IVF) techniques with remaining embryos, meaning high quality embryos that can be cryopreserved for the future, is to donate these embryos to other couples for reproductive purposes. In most cases, these embryos come from couples that have gone through double donation treatments (egg and sperm), […]
The decision to
begin trying for a child is one of the most important steps that a person can
take in life. Whether it happens naturally and or with the help of medical
intervention, it remains an important stage in life. Here are ten pieces of
advice that you can keep in mind for achieving and experiencing a pregnancy
The spermiogram is a basic tool that provides us with some of the best information to assess male fertility. It is also very useful in order to formulate a personalized treatment plan for the couple.
Conventional analysis of the semen quality, or semen analysis, is the basic routine tool that provides information about the male reproductive […]
To perform different diagnostic tests on semen, for example a seminogram, also called spermiogram, a seminal culture or spermoculture, etc., as well as for its use in the different assisted reproduction techniques (artificial insemination, in vitro fertilization or donation) a semen sample is required. The adequate sample collection requires following these simple steps:
Prior sexual abstinence […]
What is a blastocyst
A blastocyst is a 5/6 day embryo with a complex cell structure
consisting of approximately 200 cells. The blastocyst stage is the stage of
development prior to the implantation of the embryo in the mother’s womb.
This cellular structure differs in two areas that will clearly determine
the quality of the embryo and its options […]
What is Time-Lapse in in vitro fertilization, IVF?
Time-lapse technology (TTL) consists of monitoring embryonic development and making a film
of embryonic evolution by means of a video camera introduced either in a
conventional incubator or incorporated in a special incubator. A special software
reconstructs the images and allows us to view the development of the embryos.
It is often […]
For as long as we can remember, we assume that we belong to certain standards. These standards are set based on the average population, just as children in pediatric check-ups are assessed by a percentile of height and weight. As adults we are assessed by our body mass index. In both cases, we try to reach an “average” rate.
What do we […]
