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. […]

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. […]

Should IVF (in vitro fertilisation) be carried out using sedation or under anaesthetic?

Follicular puncture, or ovarian puncture, is one of the fundamental stages of in vitro fertilisation (IVF). It consists of surgery in order to retrieve eggs from inside follicles in the ovary. Excellent patient satisfaction and well-being when using these techniques reduce the emotional stress that they generate.
Huge progress has been made in the field of assisted reproduction and these steps forward will always be thought of as historical milestones in medicine. Comfort and safety are some of the most significant improvements that have been made. During the early days of IVF, eggs were retrieved by means of ovarian puncture under general anaesthetic delivered by inhalation. This technique was relatively cumbersome and egg retrieval results were low in comparison with the technique used nowadays. Patients were required to stay overnight at the clinic. […]

The adventure of deciding to become a single mother: maternity alone

If becoming a parent is an adventure in itself, taking the step to become a single mother by choice is undoubtedly a challenge. Nowadays, nobody is surprised when a woman decides to have children by herself. It is a decision she takes after having thought long and hard about it. The future mother needs to feel that she is in no way alone during the process. Instituto Bernabeu has been helping women who decide to become single mothers using assisted reproduction treatment for years. The clinic has a team of specialists who, as well as having an in-depth scientific understanding of the situation, bring a very human touch to the sensitive issue of choosing to be a single parent.

In Vitro Fertilisation (IVF). What are the potential complications?

In vitro fertilisation is the most common form of reproductive medicine and, since the issues which need to be solved are often complex, it is not always possible to get the desired result.
Over the last few decades, the risks associated with in vitro fertilisation (FIV) have gone down considerably. […]
