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 […]
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 […]
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 […]
I’m not very old but I’m not young enough to just let time go by. I’ve been thinking about this for a long time now. I’ve always wanted to have children. It’s not something I feel I can’t live without but it is something I’d like to do. I’ve been in several relationships but none […]
Embryo collapse refers to the contractions that are observed in the blastocyst and which have a connection to appropriate embryo development.
Following a number of physical phenomena, there is a build up of liquid in the cavity which ends up forming what we know as the blastocoel. A progressive accumulation of liquid leads to an increase in […]
The miracle of conception involves an intimate union between the ova and spermatozoon, appropriate evolution of the fertilised embryo and, furthermore, an ideal environment inside the uterus so that implantation can take place. Whilst this process might seem simple, it is much more complex than we might think, particularly in human beings. Only 30% of our conceptions end in […]
Mayer-Rokitansky-Küster-Hauser syndrome – or simply MRKH syndrome – is a congenital disorder (birth defect), the main characteristic of which is that the women who suffer from it do not have a uterus.
The cause of this infrequent condition (1 in 5,000 female births) is an abnormality during development of the internal genitalia during the embryo/foetus stage. As well as an […]
If we take into account that women’s oocytes develop before they are even born and that, after birth, the oocytes progressively decrease in number until they run out completely when women reach the menopause, the concept of ovarian reserve refers to the oocytes that are in a woman’s ovaries at any given time.
Assessing ovarian reserve is particularly important if […]
