Antioxidant-rich diet and improved male fertility

Infertility as a disease, is defined as the impossibility of achieving pregnancy after
12 months of regular sexual intercourse without using any contraceptive method.
The term subfertility (Zegers-Hochschild 2017) can also be used. Therefore, subfertility
describes those couples with reduced fertility.

As per the male factor, many published studies explain
what could cause about the 50% of infertility cases. […]

Immune Rejection as a Cause of Miscarriage or Implantation Failure

At some point in our lives, we have all tricked our mothers.

We are not referring to the white lies of our youth or our schoolyard antics. We are talking about the critical moment in our lives: when we were embryos.

Due to the fact that the embryo does not have the same proteins or make up as maternal tissue, it is a unique moment for the mother’s immune system.

Chromosomal alterations in repeated miscarriages

Couples who get pregnant, either naturally or through assisted reproductive techniques, are especially worried about the successful outcome of the pregnancy.

Unfortunately, some pregnancies end in miscarriage or fetal loss in the week 20 of pregnancy, when the fetus is not able to survive outside of the maternal uterus.

Semen quality parameters according to the World Health Organisation (WHO)

The spermiogram is a basic tool that provides us with some of the best information to assess male fertility. It is also very useful in order to formulate a personalized treatment plan for the couple.

Conventional analysis of the semen quality, or semen analysis, is the basic routine tool that provides information about the male reproductive […]

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 […]

What are ovarian follicles? Number, growth and other characteristics

What are ovarian follicles?

To start with, let’s state what follicles are not. Follicles are not oocytes (eggs). Many patients confuse these terms, believing that follicle equals oocyte.

The female gamete is the egg, and the male gamete is the sperm. These are the cells involved in embryos obtained after fertilization.

The follicle is a functional anatomical structure which […]
