Anyone who works in the field of fertility puts a great deal of time and effort into working out how to improve pregnancy rates. However, significantly less time is spent thinking about the period that follows gestation or the birth of a healthy child. It’s time to ask ourselves if helping to build healthy and happy families […]

Mistaking ovarian follicles for oocytes is one of the most common errors made by patients.
During ovarian stimulation, whether this is for regulating ovulation for insemination or for in vitro fertilisation, patients are administered different types of medicines depending on each case. However, there is one common aim: predicting and causing ovulation. This can be just once for patients attempting managed sexual intercourse and […]
In vitro fertilisationis a procedure that is carried out in an embryology laboratory with the aim of obtaining embryos using female gametes (ova) and male gametes (spermatozoa). The ova and spermatozoa can be retrieved from the patients (the patients’ own gametes) or from female and male donors (donated gametes).
There are many different ways of obtaining embryos which facilitate a […]
Anti-müllerian hormone (AMH) is used in reproductive medicine as an ovarian reserve marker. This hormone is detected using a simple blood analysis and, in conjunction with a follicle count ultrasound scan on the ovaries, it helps us to predict a patient’s response to stimulation. This is mainly true when patients have a limited prognosis.
In any case, despite how […]
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 […]
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. […]
What can I do to get that positive result? How can I help my in vitro fertilisation (IVF) treatment to work? Numerous factors have an impact on the success of in vitro fertilisation and getting pregnant. Living a healthy lifestyle, avoiding toxic habits, using medication appropriately and the following these 10 recommendations and pieces of advice, such as avoiding the use of perfume or ensuring that your bladder is full on the transfer day, may be a great help. […]
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 new, much more reliable, faster technique (results are obtained in 3 days) has been incorporated into our clinic and, since it is carried out directly in our laboratories, it has brought the price down to €50. The technique is carried out on a blood sample which can be taken at our clinics or a sample can be sent to us by courier.
Determining anti-Müllerian hormone levels in a woman’s blood helps us to evaluate ovarian reserve and, along with a transvaginal ultrasound used to carry out an antral follicle count, this provides us with information about her reproductive future and whether or not trying for a child is a matter of urgency.
It can also be used in order to personalise fertility treatment and to help predict how successful it is likely to be.
Cases of couples in clinics in which the female has impaired ovarian reserve are more and more common. A reduction in ovarian reserve of this kind might be expected in older women but not so in younger women, particularly when her menstrual cycles have not been irregular. […]
Follicle-stimulating hormone (FSH) is essential to reproduction. It is produced by the pituitary gland situated just below the brain (behind the palate) and is released into the bloodstream. The hormone regulates the ovaries and is involved in the processes dealing with the growth and selection of the follicle which will later release the egg during ovulation.
Fluctuations in FSH levels are responsible for menstrual cycles and also for the fact that only one egg is produced during each cycle. It is essential, therefore, that there is constant dialogue between the ovaries and the pituitary gland so that the latter can consistently produce the correct quantity of FSH for a normal cycle.
This permanent exchange means that, in cases of poor ovarian function, the pituitary gland will try to compensate for this situation by increasing FSH excretion levels. It is for this reason that FSH levels in women going through the menopause are 20 times greater than in women whose ovaries are functioning normally. Therefore, when the ovary does not respond correctly, FSH increases significantly and systematically. […]
