Using stem cells as the answer to ovarian failure: hope for the future or reality?

Significant progress has been made over the last few decades in the field of fertility in order for patients to be able to have children of their own. However, one of the greatest challenges in reproductive medicine is pregnancy in women with slim chances of obtaining their own eggs. For example, women with premature ovarian failure (in other words, egg loss at a young age) or, quite simple, women over the age of 40. […]

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. […]

What is a residual follicle? Diagnosis and treatment of a residual cyst

Residual follicle is the term given to the structure remaining in the ovary following a process of stimulation, whether this has been for insemination or during a cycle of in vitro fertilisation (IVF). Diagnosis is generally carried out using ultrasound imaging.
On the whole, before embarking on a course of ovarian stimulation, a basal ultrasound scan is carried out. The aim is to check that the ovary is resting. In other words, that it has antral follicles measuring under 10 millimetres in length. […]

What are the main causes of male sterility and infertility?

The male partner’s role in infertility has, historically, been undervalued and underdiagnosed for cultural and social reasons. However, we are now seeing progress in the analysis of men and a growing interest amongst patients in their fertility issue. Consultations for men with difficulties having children are increasingly common.
The causes of male sterility (male factor) have seen a significant increase over the last few years and are now responsible for up to 50% of cases of sterility in couples. Up to 30% of cases of infertility are due to the male factor alone and in a further 20% of cases there is a combination of both male and female factors. This is why urological examination of the male partner is so important during the couple’s fertility analysis. […]

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. […]

Get to know Dr Juan Carlos Castillo

FAMILY TRADITION IN THE FIELD OF GYNAECOLOGY
Dr Juan Carlos Castillo is a gynaecologist at Instituto Bernabeu and a renowned specialist in his field. He is married and has a young daughter. He has been part of the team at the Instituto Bernabeu Group since 2013 and is a key player in healthcare for international patients.
Dr Castillo was surrounded by medicine from a very young age. His father is a gynaecologist and he knew very early on that he also wanted to work in this field of medicine and to continue with the family tradition. He graduated with a degree in Medicine and Surgery in 1999 and, six years later, completed specialist training in gynaecology. In 2004, he did a rotation at Pennsylvania Hospital in the USA in the High Risk Obstetrics, Ultrasound and Gynaecologic Oncology departments. In 2010, he was awarded a Doctorate in Medicine with distinction from the University of Valencia. Has has been part of the medical team at the Instituto Bernabeu Group since 2013 and is one of the international patient specialists. […]

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. […]

The advantages and disadvantages of pre-implantation genetic diagnosis (PGD)

Pre-implantation genetic diagnosis (PGD) consists of studying chromosomal abnormalities and genetic abnormalities in the embryo prior to transfer to the mother. Its purpose is to ensure that children are healthy and put an end to the transmission of a specific condition.
There are two types of PGD: the PGD aimed at selecting embryos that are free of a genetic disorder affecting a single gene (PGD) and the PGD that analyses genetic diseases affecting one or more chromosomes (CCS or PGS). Their names are sometimes a cause for confusion. The post entitled Are PGD, PGS and CCS all one and the same? clarifies the differences between them. […]
