Polycystic Ovary Syndrome

The term polycystic ovary syndrome is used to define an ultrasound diagnosis characterised by the presence of 12 or more follicles in each ovary (between 2 and 9 mm in diameter) and/or an incremented ovary volume (>10 ml). Findings such as these in ultrasounds in a single ovary are sufficient in order to be able to give a diagnosis. However, since taking oral contraceptives can change ovary morphology, this diagnostic criteria does not apply to women who take oral contraceptives.
From a practical point of view, when assisted reproduction technology (ART) is being used, detection of polycystic ovaries in isolation is useful for predicting the ovary’s response to stimulation using drugs and the risk of ovarian hyperstimulation syndrome. […]

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.

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. […]

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. […]

Empty follicle syndrome

In vitro fertilisation (IVF) techniques aim to generate multiple follicles (ovarian stimulation) from which to obtain eggs which will later be fertilised. The ovarian stimulation process culminates with the use of a drug which induces the final stage of egg maturation. The most commonly used one is human chorionic gonadotropin (hCG). This final step is essential in order to obtain eggs during ovarian puncture and it also indicates when the procedure should be carried out. The origin of empty follicle syndrome (EFS) is not fully understood and, when it occurs, no eggs are obtained following meticulous ovarian puncture, despite adequate follicle growth following ovarian stimulation and normal hormone results. […]

What is a hydrosalpinx and how will it affect my fertility?

The tubes connecting the ovaries and the uterus are known as the Fallopian tubes (or uterine tubes). These structures play an essential role in natural reproduction and are responsible for receiving the egg each month and, furthermore, it is here that the union between egg and sperm takes place (fertilisation). They also enable the resulting embryo to be transported to the uterus which is where pregnancy will take place.
A hydrosalpinx is the result of an obstruction at the far ends of the Fallopian tubes which leads to the area becoming filled with liquid. This can lead to the Fallopian tubes becoming very swollen and distended, resulting in a ‘sausage-like’ appearance. In many cases, the obstruction and the liquid that has accumulated impair correct functioning of the Fallopian tube: semen does not travel up, the egg is not received by the tube and fertilisation does not take place, making achieving a natural pregnancy complicated (particularly so if both Fallopian tubes are affected). Alternatively, a hydrosalpinx can lead to pregnancy occurring within the tubes themselves (ectopic pregnancy). […]

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.
