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 […]

What is the corpus luteum?

After ovulation, follicles transform into the corpus luteum or ‘yellow body’. Corpus luteum development depends on the luteinising hormone (LH) surge before ovulation and on the number of receptors for this gonadotropin in the granulosa cells and in the theca cells.  Both types of cells go through significant changes in structure and composition and this turns the walls of the corpus […]

What tests do I need to have before egg donation treatment?

Egg donation has become an option for women who, for whatever reason, can no longer use their own ova. For example, due to poor ovarian reserve, poor oocyte quality and premature menopause.

The process is widely used in Spain. As well as exceeding organ
donations and transplants in number, we also have the largest number of egg
donors in Europe.

It […]

Can patients manage embryo and gamete transportation?

Whilst it is not part of the day-to-day routine at reproductive
medicine clinics, it is now increasingly common to have to transport biological
samples (oocytes, semen or embryos) from one clinic to another and even from
one country to another.

There can be several reasons for this such as the following:

– The
couple wishes to continue their treatment in a […]

10 things you should know if you want to freeze your eggs

1 . Does it hurt?
Egg Retrieval is painless. It is carried out by means of a simple vaginal procedure, and the patient is lightly sedated.
2. What’s the right age for preserving my eggs?
Whilst there is no minimum nor maximum age, it is advisable to undergo the procedure before 35 years of age in order to obtain a sufficient number of good quality eggs because, from 35 years of age onwards, there tends to be a decrease in both their quantity and quality. […]

What became of my embryos? Haven’t I got embryos to freeze?

These are just some of the questions that couples might ask at an important time during their treatment, just before embryo transfer.
In all cases of fertility treatment involving the in vitro fertilisation (IVF) laboratory, it is essential that all couples are given extensive, detailed and personalised information. This means talking about the embryo fertilisation and development processes.
When only a few fertilised oocytes are available as a result of poor ovarian reserve, transfer is carried out on day 2 or 3 of development in around 60% of cases because at this stage we can clearly select the embryos that are suitable for transfer. In around half of these cases it is not possible to cryopreserve embryos for future attempts. […]

Safety in the in vitro fertilisation (IVF) laboratory so that errors are avoided

A recent news item generated alarm regarding safety procedures in in vitro fertilisation (IVF) laboratories. On this occasion, a hospital in Utrecht is currently investigating 26 potential cases of confusion as a result of insemination with semen samples from different patients. We say that making mistakes is only natural, but when we are working with gametes and embryos, the error rate must be zero.
This recent news instils fear in patients since they are not familiar with the safety measures present in IVF laboratories. This fear can generate a lack of confidence in the clinic and its staff.  If we take into account that assisted reproduction treatment generates stress, news of this kind increases fears even more and generates even greater stress.

Implantation failure and repeated miscarriage. Treatment options

Successfully treating implantation failure and recurrent pregnancy loss is undoubtedly a challenge for doctors and for patients.

It is an area on which we continuously focus research at Instituto Bernabeu and, whilst we are far from finding a solution to all problems, the number of couples we are able to successfully treat is forever increasing.

An approach which does not take all 3 parties into account – the female, the male and the embryo – is incomplete. When evaluation only takes the couple into account, the reason behind the issue is only determined in under 20% of all cases. […]

Specialised healthcare in the Instituto Bernabeu endometriosis unit

Endometriosis is the presence outside the uterus of tissue from the uterus known as the endometrium (the lining that covers the uterus where the embryo embeds). It can implant anywhere in the body, except the spleen. […]

Instituto Bernabeu begins research on a new treatment for patients with poor ovarian response

From January 2016, Instituto Bernabeu will work on a clinical trial (free to participating patients) with the aim of evaluating the efficiency of a line of treatment in patients with poor response to ovarian stimulation.
The research, which has already been approved by the Spanish Drug Agency and has been published in the USA National Health Institute register, involves comparing ovarian response to two different stimulation protocols. One is conventional with drug administration starting at the beginning of the cycle. The other, new procedure carries out stimulation once it has been confirmed that the patient is ovulating. […]
