in vitro fertilisation

Why hasn’t my assisted reproduction treatment worked?

The miracle of conception involves an intimate union between the ova and spermatozoon, appropriate evolution of the fertilised embryo and, furthermore, an ideal environment inside the uterus so that implantation can take place. Whilst this process might seem simple, it is much more complex than we might think, particularly in human beings. Only 30% of our conceptions end in […]

5 indicators that the time has come to visit a fertility clinic

Infertility was a taboo subject until just a few years ago but nowadays it is common practice to turn to a reproductive medicine clinic for help when women are facing issues having children naturally. Instituto Bernabeu wants to give you a few rules of thumb for knowing when the time has come to visit a fertility clinic. […]

The advantages of an in-house ova bank

Oocytes are particularly sensitive to cryopreservation processes since they have a number of characteristics that adversely affect their survival. However, improvements to cryopreservation techniques in ova banks through the use of vitrification have made it possible to achieve survival rates that are comparable to those obtained in fresh cycles.

For a number of reasons, pursuing an efficient […]

Is the EmbryoGlue® culture medium that is used during embryo development efficient?

Culture mediums used during embryo development in in vitro fertilisation (IVF) laboratories are crucial to the exit of assisted reproduction treatment of any kind. Culture mediums have the mission of reproducing the physiological conditions inside the female reproductive system as closely as possible, embracing fertilisation up until embryo implantation in the endometrium.

In order for implantation to take place during […]

AIDS. Assisted reproduction is the best option

The risk of contracting HIV during unprotected sexual intercourse is estimated to be between 0.5 and 1%. For serodiscordant couples (one partner is a carrier), trying for a child naturally can entail an elevated risk of transmission. In cases such as these, assisted reproduction techniques are an excellent choice for getting pregnant without the risk […]

Embryonic development: the embryo on day 1 (D1)

When an oocyte is in an optimum state of maturation, ovulation takes place. This is known as day 0 of development (D0) and fertilisation by a competent spermatozoon must take place during this period.

When the oocyte is fertilised, it is then known as a zygote and
we are now on D1 of development. Certain characteristics and essential
structures need […]

The importance of embryo nutrition in achieving a successful cycle of in vitro fertilisation (IVF): metabolomics

One of the main limitations of assisted reproduction techniques are its embryo implantation failure rates. The implantation rate is the embryo’s ability to implant in the mother’s uterus. In other words, not all embryos are able to give rise to a pregnancy. Some have a greater chance of doing so than others. If it were possible to select embryos with the greatest ability to implant, it would be possible to improve assisted reproduction technique success rates. […]

Obesity and fertility

The extent of the issue
Obesity is a public health issue both in the general population and in women of childbearing age. The figures are a proof of this and, far from improving, the problem has been getting progressively worse over the last few years.
Maternal obesity in the United States of America was calculated to be 7% in 1980 and had risen up to 24% by 1999. If we take into account both obesity and excess weight, the available data indicates that the figures were 37.1% in 1999 and 40.5% in 2003.
The NHANES (National Health and Nutrition Examination Survey) reveals obesity figures (BMI or body mass index ≥ 30 kg/m2) in women of reproductive age (20 to 39 years of age) of 31.9%.
In other words, one in every three women of a fertile age is obese. […]

Infertility in men and cryptorchidism

Cryptorchidism, from the Greek words kriptos (hidden) and orquis (testicle), is the failure of one or both testes to descend to the scrotum. It is estimated that between 2 and 5% of newborn boys have this abnormality although the figure rises to 30% when premature boys are taken into account. In many cases, the issue resolves itself naturally and, as a result, at one year of age, only 1% of boys have the condition. […]

What is the impact of obesity on male fertility?

Obesity, when understood as a body mass index (BMI) in excess of 30kg/m2, is associated with numerous health issues including hypertension, diabetes, hypercholesterolemia and so on. It also affects fertility. In women, the impact of obesity is very clear. It generates hormonal abnormalities that have a direct impact on a woman’s ability to reproduce. As a result, obesity in women has been the subject of numerous studies and there are a large number of publications on the matter. […]
