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, […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
In vitro fertilisationis a procedure that is carried out in an embryology laboratory with the aim of obtaining embryos using female gametes (ova) and male gametes (spermatozoa). The ova and spermatozoa can be retrieved from the patients (the patients’ own gametes) or from female and male donors (donated gametes).
There are many different ways of obtaining embryos which facilitate a […]
