The current delay of motherhood implies that many women find themselves with a diminished ovarian reserve that limits the possibilities of achieving a pregnancy with their own oocytes. When the ovarian age is over 43 years old or when the anti-Müllerian hormone (AMH) is very low, few eggs are obtained when the ovarian puncture...

Endometriosis and Infertility
Endometriosis is an enigmatic disease. Its origin, its development, its symptoms and its consequences constantly surprise us. There are congresses dedicated to it and colleagues argue, for example, about the cause. They have been doing so for years and I believe that they cannot agree because they are all right. Let me explain: The...
Treating Recurrent Miscarriages: Science or Shamanism?
When a patient has suffered two or more miscarriages, if the problem has not been diagnosed and treated, the chances of recurrence are high and increase in direct proportion to the number of previous miscarriages. Some of us know, and others can imagine, the excitement of a positive pregnancy test. But now, I ask...
Sperm and Egg Donation: Would you like your Child to resemble you?
“Will I feel it as mine? Will she/he resemble me?” These are two of the most frequent questions at the consulting room when we tell a patient that she is going to need and egg or sperm donor to have a child. This is a very natural reaction; I call it “genetic mourning”. Faced...
Taking care of the environment is everyone’s business (part 2)
In this second part of the post I am going to detail which are the main harming pollutants I have previously mentioned. 1. Toxic chemicals: Endocrine disruptors are chemicals commonly used in industry, agriculture and at home. These substances are very resistant to biodegradation and are present in our diet and in the environment,...
Taking care of the environment is everyone’s business (part 1)
At the end of last year I followed the Climate Action Summit that was held in Madrid. One of the scientists attending the event claimed that he had never seen such a great disconnection between science, what citizens ask for and negotiators. I don’t see it that way, on the contrary, I think we’ve...
Egg donation: risks of false advertising
In recent months we have been seeing many patients who have not become pregnant after cycles of treatment with egg donation in clinics where they were “ensured” a high number of eggs or even a certain number of blastocysts. Offering or ensuring many eggs or blastocysts leads to worse pregnancy rates, because in order...
Passion for football starts before birth
As you already know, thanks to Babypod we are carrying out research studies about foetal response to different voices and tunes. In these studies, we have proved that foetuses can barely hear any noise coming from outside, but they can hear from week 16, when they measure 11 centimetres, only if the sound comes...
Anti-Müllerian hormone: What is my ovarian age?
The age stated on the ID does not always meet the age of the ovaries. When we talk about the pregnancy chances per cycle, we doctors refer to the ovarian age, and it is important that you are aware of it because it marks the level of your reserve of good eggs. To know...
Embryos have the capacity to self-repair from their second day of life
We have made a discovery about the beginning of life! We have assessed that embryos have the capacity to self-repair from the second day of life. We have presented this discovery at the most important congresses on Assisted Reproduction, as it completely changes the way embryos are assessed in In Vitro Fertilisation treatment. In order...
