In vitro fertilisation (IVF)

ICSI indications

Use of the intracytoplasmic spermatozoa injection (ICSI) technique began in the 1990s. It has been successfully used to resolve most severe cases of male sterility. Here is some information about when we use the ICSI technique:

How to deal with the diagnosis of sterility due to unknown causes

Now what? Why can’t I get pregnant?

These are undoubtedly the first two questions that come to mind after being evaluated for a fertility problem and the doctor tells you that there’s no known cause that explains why you can’t get pregnant.

Nowadays, basic sterility studies are unable to detect the exact cause of over 25% of all cases, which doesn’t mean that it can’t be diagnosed with specific tests or that a case with an unknown cause can’t be properly treated.

The miracle of embryo implantation

Embryo implantation is the process in which the human embryo adheres to the endometrium, where it continues developing. The first step of this process begins with the dialogue between the embryonic and maternal cells.

This is an extremely complex process that is currently only partially known and depends on the embryo quality, uterine receptivity and their […]

Ectopic pregnancy

What is an ectopic pregnancy?

Any
pregnancy implanted outside the endometrial cavity is called an ectopic
pregnancy. It is a condition that occurs in 1-2% of all pregnancies. Despite
the progress in its treatment and early diagnosis, its appearance and possible
complications could compromise woman’s health and her reproductive future.

Types of ectopic pregnancies

Under normal circumstances, fertilization and embryonic development until […]

NEGATIVE IVF: Everything you need to know after a failed IVF

Infertility is considered a disease that affects 17% of Spanish couples of reproductive age according to the Spanish Society of Fertility (SEF). For the affected couples, in vitro fertilization (IVF) either with own or donated eggs (egg donation) often represents the most effective treatment to fulfil their greatest desire: a healthy baby at home. However, […]

Discretionary use of intralipids in patients undergoing Assisted Reproduction Techniques

There has been a lot of discussion about therapies aimed at improving pregnancy rates; especially in patients that have gone through several cycles of treatment without positive results.

This is one of the most frustrating situations that doctors and patients can possibly have.

The inevitable question is:

What can we do to improve our chances? Isn’t there anything new?

We think that patients who have received 4 or more high quality embryos without any pregnancy should be thoroughly evaluated through an implantation failure study that should include the three fundamental elements for success: the female, male and embryo factors.

Preimplantation genetic diagnosis without biopsy non-invasive: niPGT-A

What is PGD without biopsy (niPGT-A)?

The goal of in vitro fertilization is to have a healthy child. For this purpose, in the last decades different methods have been developed to perform a genetic diagnosis of the embryos (PGD) before transferring them to the uterus. These methods have been implemented to differentiate chromosomally normal embryos […]

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 […]

Antiphospholipid Syndrome: What is it? How does it affect pregnancy?

Antibodies are proteins produced by the immune system of our organism to combat possible infections of viral or bacterial origin. In some diseases, the immune system produces antibodies that, erroneously, attack the tissues of our own body. The result of this attack is the appearance of what are known as autoimmune diseases.

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.
