Do abnormal uterine contractions cause embryo implantation failure?

Implantation failure, defined as recurrent embryo transfer failures, remains a mystery because its cause is not always clear. The contractions that take place in the uterus could be one possible explanation for it.

The uterus is a muscle and, as such, it contracts. The intensity and direction of the contractions change throughout the menstrual cycle. Over the first few days, […]

What are microRNA and what impact do they have on embryo implantation?

From the moment embryo transfer takes place up until the day when a woman takes a pregnancy test, a set of events aimed at achieving implantation (adherence of the embryo to the uterus) take place in the uterus and embryo. The process has traditionally been described as a dialogue and this is, indeed, a good way of explaining […]

What is exome genetic testing? Types of exome genetic tests

The human genome is composed of 20,000 genes. Genes contain information for synthesising all the proteins in our bodies and these proteins carry out various biological functions. The information is contained in regions called exons and they are separated by regions called introns that do not contain any information. The complete set of exons in our genome […]

Do ibuprofen and paracetamol affect fertility?

Pain killers, including paracetamol, and
non-steroidal anti-inflammatory drugs such as ibuprofen are the most
readily-available and commonly-used medicines in the world. This is because
they treat non-specific pain (migraines, high temperatures, muscular pain,
general discomfort, etc.) and because we, the general public, see them as
highly effective and accessible without a prescription.

A few years ago, use of these drugs, which […]

How do male and female contraceptives affect my fertility?

Contraceptives are any means of stopping the union between an ovum and a spermatozoon from taking place
and, therefore, avoiding pregnancy.

There are a number of available contraceptives  for men and for women and their impact on fertility varies.

So-called ‘natural’ contraceptives (the rhythm or Knaus-Ogino method, basal temperature or […]

Genetics for analysing pregnancy losses

Pregnancy losses (miscarriages) usually happen as a result of factors in the foetus or in the mother. However, in 50% of cases, the pregnancy losses that happen during the first trimester of pregnancy are caused by chromosomal abnormalities in the embryo and the number of cases are higher number in women of an advanced age. Abnormalities can be […]

What should I keep in mind when choosing a fertility clinic?

Just like with any specialist area of medicine, when we need to turn to a reproductive medicine clinic, we have a number of concerns and we need to have a clear understanding of what our needs are and what we expect from an assisted reproduction clinic. It is very important to choose carefully because they […]

When can I find out how many of my ova have fertilised?

Ova and spermatozoa are needed in order to be able to perform in vitro fertilisation treatment. They are taken to the in vitro fertilisation laboratory so that, once they have been appropriately prepared, they can be joined together and fertilise.

Unfortunately, biology is not an exact science and the uniting a spermatozoon and an ovum does not always create an […]

Rh incompatibility: could it affect my baby during pregnancy?

A person’s blood group is determined by a number of proteins
that are found on the surface of red blood cells. There are 4 main blood groups
depending on if these proteins are present or not: A, B, AB and 0. An
additional protein known as factor Rh has also been located on the surface. If
a person has […]

My personal choice to use artificial insemination and become a single mother
