Fertility Treatment Medication

There are many drugs that are used when a couple undergoes a fertility treatment (IVF, insemination, egg donation, etc.). Some are very simple to use and have virtually no side effects and others are more complex and have greater side effects.

We shall now discuss the most commonly used drugs, what they are and their side […]

Poor Ovarian Response: progress in genetics

Ovarian stimulation is key in results obtained as a results of assisted reproduction techniques. Daily clinical practice shows us that ovarian response can vary substantially from one woman to another. With this in mind, we can diagnose a patient as a poor responder when three eggs or less are obtained.

This situation affects more and more women every day. They require specialised healthcare and personalised protocols and, in response to this need, Instituto Bernabeu has a Poor Ovarian Response Unit that deals with multidisciplinary diagnosis and treatment.

For patients under this category, obtaining one or more eggs can mean the difference between failure and pregnancy and this makes any steps taken to increase the number of available eggs absolutely essential.

Accumulation of oocytes in patients with a low response

The number of oocytes retrieved is a key prognostic factor in In Vitro Fertilisation (IVF) treatments. Chances are greater the greater the number of retrieved oocytes is, until the moment when 6 to 8 oocytes have already been retrieved.

For this reason, care of patients with a Low Response should be especially thorough, both as regards the chosen protocol for ovarian stimulation and the processes of oocyte retrieval and management at the laboratory. In these cases, retrieving an extra oocyte may considerably increase the chances of success.

While many of these patients benefit from the implementation of specific stimulation protocols and the use of adjuvant therapies, some of them will be refractive and will yield a very poor response.

The appearance of vitrification as a successful technique to freeze both oocytes and embryos has stirred new expectations in patients with a low response at the possibility of accumulating vitrified oocytes from several stimulation cycles. This way, after performing a number of oocyte collection cycles and once collecting a number between 6 and 8 oocytes has been achieved, the processes of fertilisation begin. In this case, prognosis is more favourable, as patients now have more or less the same number of oocytes as those patients with a normal response.

Anti-Müllerian Hormone (AMH): Know the age of your ovary

What is Anti-Müllerian hormone?

It is a protein that plays a key role in sexual
differentiation during the foetal stage. In males, it is produced by a specific
type of testicular cell (Sertoli cells). In the presence of this hormone, the
development of the male phenotype begins. However, when the Anti-Müllerian hormone
is absent, the differentiation of certain female structures […]

Endometrial polyps: what are they, how are they formed and what are the symptoms and treatment?

What are endometrial or uterine polyps?

Endometrial polyps are cell formations that project from the
endometrial cavity.

They are a common gynaecological pathology experienced by 20%
of women. They appear most commonly in women aged between 40 and 65.
However, women of all ages can have them.

They contain endometrial glands, stroma and blood vessels. They
attach to the uterine wall across […]

What is ovarian reserve? What role does it play in fertility?

What is ovarian reserve?

Ovarian reserve can be defined as the number of ova in a woman’s
ovaries at any given point during her childbearing years.

In the case of men, spermatozoa production remains constant between puberty and senescence.  Recent studies confirm that spermatozoa quantity and quality can diminish over time. However, men generally remain fertile throughout their […]

Time-lapse in assisted reproduction. Current situation

What is Time-Lapse in in vitro fertilization, IVF?

Time-lapse technology (TTL) consists of monitoring embryonic development and making a film
of embryonic evolution by means of a video camera introduced either in a
conventional incubator or incorporated in a special incubator. A special software
reconstructs the images and allows us to view the development of the embryos.

It is often […]

Endometriosis and Fertility

What is Endometriosis?

Endometriosis is a benign, inflammatory, chronic and incurable disease that affects the health and fertility of nearly 180 million women worldwide. To get a global idea, it affects 1 in 10 women of reproductive age. Although it is an increasingly known disease  in our society, there is still a large part of the […]

Normal and abnormal embryo division

For as long as we can remember, we assume that we belong to certain standards. These standards are set based on the average population, just as children in pediatric check-ups are assessed by a percentile of height and weight. As adults we are assessed by our body mass index. In both cases, we try to reach an “average” rate.

What do we […]

Difference between identical and fraternal twins

Before establishing the biological origin differences between identical and fraternal twins, let’s make a quick note on the etymology of both words.

Etymologically both terms have the same origin (Latin gemellicium) and were used interchangeably to refer to children born in the same delivery. The only difference was the use of the term fraternal twin in the popular speech twin and identical twin in the cultivated speech. However, the semantic evolution of both words has been accompanied by the numerous advances in the field of genetics and knowledge of the development of the human embryo. In fact, since they differ in the latest edition of the dictionary of the RAE:
