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 […]
If we take into account that women’s oocytes develop before they are even born and that, after birth, the oocytes progressively decrease in number until they run out completely when women reach the menopause, the concept of ovarian reserve refers to the oocytes that are in a woman’s ovaries at any given time.
Assessing ovarian reserve is particularly important if […]
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 extent of the issue
Obesity is a public health issue both in the general population and in women of childbearing age. Far from improving, the problem has progressively increased over the last few years.
A study published in the journal The Lancet concludes that 13% of the world population has weight
issues. In Spain, there is a growing […]
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. […]
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. […]
Breast cancer is the most common malignant tumour found in women and it is the main cause of death in women due to cancer in the world.
Over the last few years, there has been an increase in this pathology in younger women and, at the same time, treatment has taken breast cancer survival rates to almost 85%. These facts and a pronounced trend towards delaying motherhood has generated a group of women whose ability to reproduce has been negatively affected before they have had the chance to turn their dream of becoming a mother into a reality. […]
The advantages of comprehensive chromosome screening (PGS/PGT-A/CCS) in women of an advanced maternal age
Women currently seek guidance on reproduction at a much older age than they did some years ago. As a result, amongst the women who undergo fertility treatment, there is a significant group of women of an advanced age and their prognosis is poorer. This is a huge challenge for reproduction specialists. […]
Hormones are messengers that are present in all multicellular organisms – be they animal or plant organisms – that coordinate the functions of each part of that organism.
The sex hormones par excellence are oestradiol in females and testosterone in males. However, the adrenal glands in men and women produce both hormones and they are both necessary for normal development of the two sexes. […]
A patient can be classified as having poor response when the number of oocytes obtained during a cycle of in vitro fertilisation is under what was expected. The criteria generally used to label a patient as a poor responder is when 3 or fewer oocytes are retrieved and she has incredibly low ovarian reserve markers (fundamentally, AMH and AFC). […]
