Several courses of unsuccessful fertility treatment. When has the time come to give up?

Whilst the success rates of assisted reproduction treatment are increasingly higher, in a small number of cases, couples who have undergone several courses of in vitro fertilisation without having achieved a viable pregnancy decide to give up treatment for good.
One of the main reasons why couples do not have children is because they give up on treatment too soon. For couples who keep on trying, the chances of having a child are high. […]

How can the best spermatozoon for fertilising an egg be selected?

Selection of the spermatozoon capable of fertilising an egg and generating a viable embryo is a subject that has been covered in a great number of studies aiming to provide this question with an answer.
Although assisted reproduction techniques have been used for dealing with fertility issues for many years, there is still room for improvement in terms of the results obtained. First of all, we need to fully determine the role of the spermatozoon because it tends to be thought of simply as the transporter of the father’s genetic material with no impact on later development. This idea has already been turned on its head and sperm does not only play a role in the fertilisation process. An abnormal spermatozoon can give rise to abnormal embryos and can even influence implantation failure. […]

Should embryos with chromosomal mosaicism be rejected?

When good quality embryos do not implant correctly or lead to pregnancy loss, in vitro fertilisation (IVF) does not provide us with the results we had hoped for. This is often because the embryo is a carrier of abnormal chromosomes. Fortunately, in our clinic, we have access to the very latest in embryo chromosome diagnosis techniques such as array CGH and next generation sequencing (NGS). We can use this technology to detect abnormalities in the embryo that will cause pregnancy loss or that will lead to the birth of a child with chromosomal abnormalities such as Down’s Syndrome, also known as trisomy 21. As such, we can use these techniques to select and transfer the embryos with the greatest chance of leading to the birth of healthy child. […]

Should I tell my children they were born as a result of in vitro fertilisation (IVF) or egg donation?

One of the questions that couples frequently ask me in their appointments is if they should tell their child that they were the result of IVF or egg donation? How will the child react when told?
The answer needs to be thought through and only you will find the one that’s right for you. Your personality is based on a number of factors such as principles, education, opinions (prejudices), beliefs and experiences that shape your thoughts and, as such, the way you feel and act. In order to get a clear answer, I suggest you put those opinions aside and take all the time you need. Set your irrational thoughts aside and the answer will come to you. There are couples who do not know what they will do until their child is born. However, once you’ve decided, don’t doubt your choice. Accept the consequences and be consistent. Whatever you decide to do, be sure that it makes you happy because being happy is a decision. […]

Does being sexually aroused improve semen quality?

It has been scientifically proven that there are risk factors in our daily lives that have a negative impact on the quantity and quality of spermatozoa. These factors include emotional stress, doing a physically demanding job, sitting for prolonged periods of time, elevated local temperature, having high blood pressure and taking certain drugs over a prolonged period of time.
With this in mind, are there factors in our daily lives that are good for semen quality? […]

What are an embryo’s nutritional requirements prior to transfer to the mother?

During in vitro fertilisation processes, for the first few days of their lives, human embryos have to develop outside the mother’s body in special incubators.  Temperature and pH conditions need to be optimum and embryos also need to have access to all the necessary ingredients in order to feed and, in doing so, meet their energy requirements. Culture media are used for this. […]

New examination aimed at testing couples with recurrent implantation failure

Instituto Bernabeu focusses on providing personalised solutions, particularly in cases of patients with a difficult reproductive prognosis (low ovarian reserve and recurrent implantation failure (RIF)).
Carrying out a number of empirical tests and treatments has, on occasions, been put forward as an option in the case of patients suffering from recurrent implantation failure. The latter have proven to be of questionable efficacy and the former have proven to be of limited or no use.
One of the proposed strategies for patients with recurrent implantation failure (RIF) that is providing many of these cases with solutions, is IVF (in vitro fertilisation) with elective freezing and biopsies on all embryos so that the frozen embryos can later be transferred during a natural cycle. In other words, without any hormone treatment.
It is possible to recreate the conditions under which transfer takes place during treatment of this kind by carrying out a mock cycle and evaluating a series of parameters that can influence transfer success. […]

How might salpingitis or inflammation of the fallopian tubes affect my fertility?

In order for natural conception to take place, three basic factors need to be come together: ovulation needs to take place, there needs to be an appropriate quantity of spermatozoa with appropriate mobility in the ejaculate and, in third place, the uterine tubes need to be permeable. The latter is essential in order for both gametes to join together (egg and sperm) and for fertilisation to then take place. […]

Is it possible for me to get pregnant if I only have one fallopian tube? What if I have neither of them?

The uterine tubes (or fallopian tubes) are muscular tubes leading from the ovaries into the uterus. The uterine tubes are responsible for collecting the egg each month. Fusion between the egg and the sperm (fertilisation) also takes place inside them. The resulting embryo is taken to the uterus where the pregnancy will evolve. Evidently, the fallopian tubes fulfil essential roles in natural reproduction linked to ovulation, fertilisation and pregnancy. In fact, diseases or abnormalities in the uterine tubes are the cause of up to 30% of all cases of sterility. […]

A less invasive, simpler technique: SOFT IVF or MINI IVF

Having a sufficient number of mature egg cells is one of the key steps to obtaining excellent results in a cycle of in vitro fertilisation (IVF). In order to achieve this, the ovaries need to be stimulated and, contrary to what happens during a natural cycle, the ovaries need to simultaneously mature an appropriate number of eggs.
The most commonly used stimulation protocols are based on the use of doses of follicle-stimulating hormone (FSH). These may or may not be administered along with other drugs and vary between 150 and 300 IU/day. The response will be somewhere between 7 and 15 follicles. […]
