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 […]

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 […]

5 indicators that the time has come to visit a fertility clinic

Infertility was a taboo subject until just a few years ago but nowadays it is common practice to turn to a reproductive medicine clinic for help when women are facing issues having children naturally. Instituto Bernabeu wants to give you a few rules of thumb for knowing when the time has come to visit a fertility clinic. […]

How can we improve the chances of pregnancy for women who are obese?

The extent of the issue

Obesity is a public health issue both in the general population and in women of childbearing age. Far from improving, the problem has progressively increased over the last few years.

A study published in the journal The Lancet concludes that 13% of the world population has weight
issues. In Spain, there is a growing […]

What is the ‘implantation window’ in fertility treatment?

The ‘implantation window’ is the name we give to the period of time during which the endometrium in the mother’s uterus is in an appropriate state for embryo implantation to take place.

Implantation is a critical and very precise process during which the embryo makes contact with and penetrates the endometrial tissue in the mother, making gestation possible. This […]

Is the EmbryoGlue® culture medium that is used during embryo development efficient?

Culture mediums used during embryo development in in vitro fertilisation (IVF) laboratories are crucial to the exit of assisted reproduction treatment of any kind. Culture mediums have the mission of reproducing the physiological conditions inside the female reproductive system as closely as possible, embracing fertilisation up until embryo implantation in the endometrium.

In order for implantation to take place during […]

The link between thrombophilia and recurrent implantation failure

The percentage of pregnancies achieved following assisted reproduction treatment has progressively increased over the years but we still have a long way to go before we achieve optimum results. This is why alternative treatment options that have not already been attempted are taken into account when several courses of treatment have not given a positive result.

It has been […]

Embryonic development: the embryo on day 1 (D1)

When an oocyte is in an optimum state of maturation, ovulation takes place. This is known as day 0 of development (D0) and fertilisation by a competent spermatozoon must take place during this period.

When the oocyte is fertilised, it is then known as a zygote and
we are now on D1 of development. Certain characteristics and essential
structures need […]
