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. […]

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. […]

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. […]

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. […]

How long should I wait following unsuccessful assisted reproduction treatment?

We are often asked this question at our clinic because, following an unsuccessful attempt at in vitro fertilisation there is always the hope of another go. The recommendation has always traditionally been to leave a space of 3 months between each ovarian stimulation, which can be stressful for patients whose age is against them.
Research has been carried out with the aim of determining whether or not a wait is necessary. The studies compare a wait of one month with a wait of three months and the results obtained are the same.
It is for this reason that we do not recommend putting off a new attempt for more than one month in patients who need to carry out treatment as soon as possible. […]

Asthenozoospermia: What is it? How can it be detected? What course of treatment can be used in order to get pregnant?

Asthenozoospermia is a decrease in the percentage of motile sperm in a sperm sample and it is identified by means of a seminogram or semen analysis.
Nowadays, seminograms are a basic tool which provide us with information in order to evaluate a man’s fertility and they are very useful when determining personalised treatment for the couple concerned. The analysis can be used to evaluate numerous factors such as the concentration, motility and morphology of sperm present in the ejaculate, amongst others.
According to the criteria included in the 5th edition of the World Health Organisation (WHO) (2010) manual, a man has asthenozoospermia when less than 32% of sperm in the ejaculate have progressive motility (sperm which move around) or when there it less than 40% total motile sperm (motile sperm which do and do not move around). […]

A negative beta hCG test. Now what?

What happens following the wait (‘the beta hCG wait’) which generates so much anxiety whilst, at the same time, creating the hope that our lives may be changed forever when, in the end, the result is negative?
Many patients say that the absence of symptoms meant that they knew what was coming; others were also expecting the worst because they had begun to bleed prior to getting the result of the analysis.
It’s important to point out that the presence or absence of ‘symptoms’ which women associate with pregnancy are not a means of diagnosis. It’s also important to clarify that vaginal bleeding of varying intensity is not infrequent prior to the programmed pregnancy test date and this does not necessarily mean that the result will be negative. Indeed, the results obtained from an analysis of the pregnancy hormone in blood is the only reliable proof available. A urine analysis is also an option but needs to be carried out a little later on and is not one hundred percent reliable. […]

Teratozoospermia and male infertility

Teratozoospermia is an increase in the percentage of abnormal sperm in a sperm sample and it is identified by means of a seminogram or semen analysis.
According to the criteria in the 5th edition of the World Health Organisation (WHO), 2010 manual, a man has teratozoospermia when the percentage of normal spermatozoa in the ejaculate is below 4%.
Defects in sperm […]

Progesterone and its role in reproduction

What is progesterone? Just a simple look at the word itself gives us an idea of what its functions are. PROGESTERONE: the hormone which facilitates pregnancy. This is a good point from which to start out.
Progesterone plays an essential role in pregnancy and it has many and varied effects. It is a natural substance which is secreted from the ovaries following ovulation and continues throughout the second half of the menstrual cycle. Progesterone ensures that a woman’s uterus is receptive and, when production is insufficient, the embryo does not implant correctly or runs a high risk of leading to a miscarriage. It also relaxes the muscles in the uterus, making it better suited for the early days of pregnancy. […]

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: […]
