Helping a relative or friend with fertility issues.

Infertility can have an impact on many levels: it can affect the person with the issue as well as that person’s partner. When a couple embarks upon such a significant project as maternity and is faced with failure month after month, despite every effort, negative feelings such as anger, resistance, frustration, despair and sadness arise and they are difficult to manage. This can lead to feelings of depression and anxiety. On the whole, it is an issue which patients find difficult to speak about and, as a result, they are not surrounded by a strong social or family support network.

If you know anyone who may be suffering from the emotional impact of infertility, here are 10 pieces of useful advice: […]

A boy or a girl: can I choose my baby’s gender?

Whilst it is technically possible to choose a child’s gender using pre-implantation genetic diagnosis, Spanish law prohibits selecting a baby’s sex, except with a view to avoiding the transmission of genetic diseases associated with the X chromosome. Such is the case, for example, of haemophilia A.
Law 14/2006 indicates that pre-implantation genetic diagnosis may only be used in order to detect serious genetic diseases or those which compromise the viability of an embryo. Therefore, this technique may not be used in order to select a future baby’s gender. Any other use of this technique is a serious offence which is punishable by law. […]

Cytomegalovirus (CMV): What is it? How is it transmitted? What are its symptoms? How can it be treated?

Cytomegalovirus (CMV) is a virus from the family Herpesviridae. We also find the chickenpox virus, herpes simplex and the mononucleosis virus in this family.
Infection with CMV is very common since it is present worldwide and can affect anyone. On the whole, it is an infection which does not usually cause any serious health issues. Once the virus has infected a person, it will remain in that person’s body for the remainder of his or her life. In fact, it is usually inactive or latent for a long time and it does not tend to reactivate unless the person’s defence system (immune system) is affected. Most people who are infected by the virus and who do not have serious health issues do not, on the whole, have any symptoms which might cause them to believe that they are infected with CMV. People who do develop some symptoms may suffer from a high temperature, swollen lymph glands, muscle pain or tiredness.
However, in the case of babies infected with the virus during pregnancy or childbirth and in people with a weak immune system, it is considered to be a significant public health problem since it can cause serious illnesses. […]

Why does embryonic arrest sometimes happen during in vitro development?

Many factors can intervene in arrest processes during embryo development which mean cell division is detained and, therefore, it is not possible to implant the embryo in the mother’s uterus and bring about a pregnancy.
In the first instance, the conditions for development are essential.  Embryos that develop in vitro are subjected to a number of artificial conditions that do not exist in vivo and which will always be less than optimum. Embryos which were apparently viable can suffer embryonic arrest. Huge efforts have been made over the last few years to try and mimic what happens inside the mother and replicate those conditions in laboratory processes.  Most of all, the concentration of oxygen in incubators has been reduced, going from 20% down to 5%. The composition of the culture means has also been improved. This, along with exhaustive monitoring of pH and osmotic concentration, means that we can routinely carry out prolonged embryo development up to blastocyst stage in order to achieve improved embryo selection and increase pregnancy rates.

Reduced mobility and fertility

Reproduction issues always need to be dealt with with a degree of sensitivity. When there is also a disability within the couple, the emotional side of things calls for even greater care and steps should be taken in order to deal adequately with any implications the disability in question has from a medical point of view.
In 2006, the United Nations (UN) published guidelines on the rights of people with reduced mobility. These guidelines indicate disabled people’s rights across all levels of society and include the right to have children and access to sexual health.
At Instituto Bernabeu, we aim to comply with the aforementioned guidelines and provide our patients with the means and solutions they need and which adapt to the circumstances of each physical disability. This covers disabilities resulting from a genetic condition (hereditary), disease or an accident and, from a fertility point of view, each case is given personalised treatment. […]

Beta hCG (β-hCG) result table

ACCESS INFORMATION PRIOR TO THIS POST ON BETA
β-hCG (human chorionic gonadotropin) is a glycoprotein that is initially secreted by trophoblast cells in the embryo shortly after it implants in the uterus. The rapid increase in serum levels of hCG following conception means it is an excellent early indicator of pregnancy. It’s also a parameter which is widely used for monitoring that a pregnancy is progressing correctly.
On a physiological level, hCG triggers the corpus luteum and thus facilitates progesterone and oestrogen synthesis. Progesterone stimulates the maturing of blood and capillary vessels that help the foetus to develop correctly.
hCG levels can be measured in blood or in urine.
Urine tests have a detection limit of 20 to 100 mUI/ml depending on the brand. If the measurement is to be taken in urine, a sample of the first urine of the day is recommended. This is particularly true during the early days of pregnancy because, if the urine is too diluted, the test can return incorrect negative results.
hCG levels in blood can be used to detect levels as low as 5 mUI/ml and the concentration levels of the hormone can therefore be calculated.
hCG levels in multiple pregnancies are 30-50 % higher than in pregnancies where there is only one foetus. However, a multiple pregnancy should be confirmed by means of an ultrasound.

Ovarian stimulation: What is it? Are there any risks involved?

During the first few days of a period, a complex process takes place in the ovaries. The first step is to gather and initiate development in several follicles that contain eggs. Following this, only one egg is selected and it then develops. A mature egg is released during ovulation.

Recurrent pregnancy loss: an issue that does have a solution

Clearly one of the most difficult situations a couple trying for children may have to face is pregnancy loss. Suffering is even greater when, prior to this, the couple has gone through fertility treatment such as in vitro fertilisation, insemination or egg donation.
Pregnancy loss is not always the result of an illness or underlying abnormality. It can be the response nature provides in order to block the development of an abnormal embryo. In fact, when the tissue from the pregnancy loss is examined, a large number of chromosomal abnormalities can be detected. […]

Recommendations following embryo transfer

Transfer is undoubtedly one of the most important steps in assisted reproduction treatment.
When the patient steps out of the transfer room, a new beginning takes place and the experience will be totally different to what she has undergone up until that point. The embryos have now been transferred and the countdown to the pregnancy test has begun.
It’s important that patients understand that when they go to the toilet to urinate following embryo transfer, the embryos do not ‘fall out’ nor do they get lost since they are situated inside the uterus, a part of the body which is quite different to the one we use for urinating. […]

What does embryo biopsy involve?

Preimplantation Genetic Diagnosis (PGD) is a tool designed to “get to know” the embryos genetically before they are transferred into the mother’s uterus. Thanks to this technique, we can study their chromosome count and find out if they are carriers of a hereditary disease. This information helps us to select the embryos that will produce healthy babies. Yet, how can we find that information?
Today, the only way to find genetic information about embryos is by performing an embryo biopsy. What does embryo biopsy involve?
To explain the biopsy procedure we should keep in mind that our point of departure is EMBRYOS. Embryos are retrieved after performing an assisted reproduction cycle, preferably by Intracytoplasmic Sperm Injection (ICSI), and their development is assessed during the culture period until day 3 or day 5.
