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, […]

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 […]

Genetics for analysing pregnancy losses

Pregnancy losses (miscarriages) usually happen as a result of factors in the foetus or in the mother.

Anti-müllerian hormone (AMH) is no longer a crystal ball

Anti-müllerian hormone (AMH) is used in reproductive medicine as an ovarian reserve marker. This hormone is detected using a simple blood analysis and, in conjunction with a follicle count ultrasound scan on the ovaries, it helps us to predict a patient’s response to stimulation. This is mainly true when patients have a limited prognosis.

In any case, despite how […]

Why hasn’t my assisted reproduction treatment worked?

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 […]
