Absent uterus or Mayer-Rokitansky-Küster-Hauser syndrome: what can I do?

Mayer-Rokitansky-Küster-Hauser syndrome – or simply MRKH syndrome – is a congenital disorder (birth defect), the main characteristic of which is that the women who suffer from it do not have a uterus.

The cause of this infrequent condition (1 in 5,000 female births) is an abnormality during development of the internal genitalia during the embryo/foetus stage. As well as an […]

What role does the immune system play in fertility?

From an immunological point of view, pregnancy is a unique set of circumstances because a woman’s body has to ‘withstand something that is foreign to it’. The mother has to carry the embryo and, in order to do so, her immune system needs to accept co-existence with cells that are at least half foreign in origin. Using a […]

Progress in treatment for patients with poor ovarian response

Personalising courses of treatment is undoubtedly currently the
most important area of change in the field of medicine. A specific strategy should be designed
depending on each patient’s individual characteristics.

One of the key areas for developing personalised medical healthcare is the use of pharmacogenetics. A patient needs different doses or types of pharmaceutical drugs depending on certain genetic variations. […]

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 […]

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. […]
