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

What is embryo collapse? Does it affect how the embryo implants?

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 […]

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 […]
