Anti-müllerian hormone (AMH) is no longer a crystal ball

Anti-müllerian hormone (AMH) is used in reproductive medicine as an ovarian reserve marker. This hormone is detected using a simple blood analysis and, in conjunction with a follicle count ultrasound scan on the ovaries, it helps us to predict a patient’s response to stimulation. This is mainly true when patients have a limited prognosis.

In any case, despite how […]

The latest in pre-implantation genetic diagnosis (PGD)

Pre-implantation genetic diagnosis(PGD) consists of studying chromosomalabnormalities and genetic abnormalities in the embryo prior to transfer to the mother. Itspurpose is to ensure that children are healthy and to bring thetransmission of a given condition to an end.

Significant progress that has revolutionised this area ofreproductive medicine has been made over the last few years and specificallywith regards to one type […]

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. […]

CCS (Comprehensive Chromosome Screening) and unexplained sterility

Any couple that turns to a fertility clinic undergoes a number of tests in order to diagnose the fertility issue that is making natural conception impossible. It is estimated that, at the end of the process, 1 in 4 couples are provided with no apparent reason for the reproduction issue. In these couples, no significant findings came up in the diagnostic tests carried out both on the male and the female partner.
Circumstances such as these generate a great deal of uneasiness and doubts in couples because, with no known reason for their infertility, they feel as if they were in no man’s land. […]

How are seminograms interpreted?

A seminogram, or semen analysis, is a basic analysis of a semen sample with the aim of determining semen quality. In order to carry out the analysis correctly, the patient needs to refrain from sexual intercourse for a period of 3 to 5 days. That is, he must not ejaculate during that period and the sample must be obtained by means of masturbation.
The most relevant parameters evaluated in a semen sample include: […]

Genetic compatibility in couples

When faced with fertility issues, many people believe that this is often due to the couple’s incompatibility. The reason behind this inability to fall pregnant is often unknown and quite simply a mystery due to some form of irresolvable  ‘genetic issue’. When faced with such circumstances, we can but give in and accept it and, as with all popular beliefs, there is some truth in it.
It’s estimated that around 20% of reproduction issues are down to genetics. In fact, many of the tests carried out as part of patient fertility analyses in our clinic, aim to determine if there is a genetic issue behind the couple’s difficulties falling pregnant. […]

Can I choose the sex of my embryos when I undergo embryo transfer?

The human genome consists of 46 chromosomes: 23 of these are inherited from our father and the other 23 are inherited from our mother. Our organism’s entire genetic make-up is stored in these chromosomes. The 23 pairs are organised as follows: 22 pairs, known as autosomes, and one pair of sex chromosomes (X and Y) which differentiate the two sexes (XY for males and XX for females).
From a technical point of view, using pre-implantation genetic diagnosis, we have the means of analysing an embryo’s entire chromosomal make-up. This technique, which is known as PGS/PGT-A/CCS (Comprehensive Chromosome Screening), means additional or a lack of any chromosomes in the embryo can be detected. Therefore, we can use PGS/PGT-A/CCS to analyse the entire make-up of the embryo and determine that there are neither DNA excesses nor deficiencies which will stop the embryo from developing properly. But, if we focus on the sex chromosomes, we can also determine if the analysed embryo has two X chromosomes and will, therefore, be a girl (XX) or one X chromosome and one Y chromosome (XY) and will be a boy.
