Relevance of reproductive counselling

Before seeking pregnancy, women generally plan their gestation and take nutritional supplements, such as folic acid, which is fundamental for the prevention of defects of the neural tube in the foetus.
For greater assurance that this stage will be happy and free from complications, it is important to undergo prior reproductive counselling. Furthermore, it is appropriate to consider the need for some kind of specific additional counselling, according to the characteristics of the case. […]

Embryo transfer on day 4 – why not?

In most laboratories, embryo transfer traditionally takes place on day 2 to 3 of culture, or during blastocyst stage, whilst embryo transfer on day 4 is an alternative that has not commonly been adopted into laboratory practice.
When compared with embryo transfer during early stages, blastocyst transfer is generally accepted as superior. This is mainly for reasons of improved synchronisation between the embryo and the endometrium and more objective embryo selection once the genome has been activated. It means that a smaller number of embryos can be transferred, thus avoiding the risk of a multiple pregnancy. […]

IMSI, does it improve the results?

IMSI, or Intracytoplasmic morphologically selected sperm injection, is a technique that became popular over a decade ago.  It uses a very high-power microscope to examine and select the sperm that will then be introduced in the egg with the aim of increasing the possibilities of a successful implantation and reducing the probabilities of miscarriage. […]

Fragment removal

From the very moment when sperm fertilises an ova, a new embryo starts developing and a large number of cell divisions take place. This embryo development is observed in an in vitro fertilisation laboratory up until the blastocyst stage (day 5 or 6 of development). Sometimes during the cell division process, fragments of the embryo become isolated between cells that have developed correctly. These fragments come from embryo cell remains and can stop the embryo from developing correctly. One of the negative impacts consists of issues reaching the blastocyst stage and the posterior impact on implantation in the uterus. In fact, embryo fragmentation is one of the most significant characteristics used to determine embryo quality. […]

Children born to blood relatives

The question of relationships between blood relatives has been approached in many different ways throughout the course of history. There have been times when relationships of this kind have been commonly accepted, whilst at other times they have been prohibited for moral, religious or even scientific reasons.
Relationships between blood relatives were actively encouraged in some primitive cultures in order to promote clan unity. For example, marriage between members of the same family in ancient Egypt. The legislation in a large number of US States currently prohibits and actively pursues relationships between first cousins. […]

Sterility and Infertility

Are sterility and infertility the same?
No, they are two completely different concepts.
Sterility is the inability to conceive whilst infertility is the inability to complete a full term pregnancy and give birth to a healthy child. […]

What does an embryo biopsy entail?

Pre-implantation genetic diagnosis (PGD) is a technique that provides a ‘genetic understanding’ of the embryo before it is transferred to the uterus. Thanks to this technique, we are able to study the embryo’s chromosomal make-up and determine if it is a carrier of a hereditary condition of any kind. This information helps us to select the embryos that will lead to the birth of a healthy child. But how do we obtain this information?
Work is currently being carried out to discover non-invasive means of gathering genetic information from the embryo but, to date, the only means is an embryo biopsy. What is an embryo biopsy? […]

What impact does cholesterol have on my fertility?

Cholesterol plays an essential role in ensuring that our organism works correctly. Its impact on the heart is still given priority in terms of analysis because of the elevated impact and frequency of diseases of this kind.
Whilst all the other areas of influence have been analysed to a much lesser degree, in some cases such as infertility, the effects of this essential component are now starting to come to light.
What is the importance of cholesterol in fertility? […]

Reproduction and genetics guidance

Genetics guidance is the exchange through which an expert in genetics provides patients and their families with information and support on a genetic condition, inheriting that condition, the risk of recurrence and the implications for the individual and his or her family.
The aim of genetics guidance is to support the decision-making process whilst taking the patient’s values and beliefs into account, and to proceed based on the decision taken.
In the specific case of reproduction guidance, it is a question of guiding couples who are in a reproductive stage of their lives and who wish to have children and/or who are currently expecting a child. Therefore, we generally have two types of patients who need reproduction guidance. Whilst there are fundamental differences between the two, the aims of the guidance process remain the same and include: […]

What is a progesterone deficit? Administration and side effects

Progesterone is one of the most important hormones in a woman’s metabolism and fertility. It is produced by the ovaries following ovulation during a normal menstrual cycle but when a woman is pregnant the placenta takes over responsibility for production. Its main roles consist of preparing the endometrium (internal layer of the uterus) for implanting a fertilised ovum and sustaining pregnancies.  It also plays an important role when a woman is breastfeeding because it helps to prepare the mammary glands for milk production. […]
