The ethical issues faced in assisted reproduction clinics

Although Spanish law led the way in regulating the practice of assisted reproduction and made significant progress in comparison with legislation in neighbouring countries, and even though Spain is, furthermore, a leader in the field both in terms of the quality of some of its clinics and health specialists, as well as in terms of the excellent results obtained, it […]

What is adenomyosis?

Adenomyosis is defined as an abnormal presence of endometrial tissue inside the muscular lining of the uterus.
Adenomyosis is not a well-known condition because diagnosis is not easy. Clinical expression can range from no symptoms whatsoever to heavy, lengthy periods and dysmenorrhoea. […]

Is it possible for me to get pregnant if I only have one fallopian tube? What if I have neither of them?

The uterine tubes (or fallopian tubes) are muscular tubes leading from the ovaries into the uterus. The uterine tubes are responsible for collecting the egg each month. Fusion between the egg and the sperm (fertilisation) also takes place inside them. The resulting embryo is taken to the uterus where the pregnancy will evolve. Evidently, the fallopian tubes fulfil essential roles in natural reproduction linked to ovulation, fertilisation and pregnancy. In fact, diseases or abnormalities in the uterine tubes are the cause of up to 30% of all cases of sterility. […]

Should IVF (in vitro fertilisation) be carried out using sedation or under anaesthetic?

Follicular puncture, or ovarian puncture, is one of the fundamental stages of in vitro fertilisation (IVF). It consists of surgery in order to retrieve eggs from inside follicles in the ovary. Excellent patient satisfaction and well-being when using these techniques reduce the emotional stress that they generate.
Huge progress has been made in the field of assisted reproduction and these steps forward will always be thought of as historical milestones in medicine. Comfort and safety are some of the most significant improvements that have been made. During the early days of IVF, eggs were retrieved by means of ovarian puncture under general anaesthetic delivered by inhalation. This technique was relatively cumbersome and egg retrieval results were low in comparison with the technique used nowadays. Patients were required to stay overnight at the clinic. […]

Instituto Bernabeu discovers fertility genetic variants

Following years of research, the Poor Responder Unit at Instituto Bernabeu has, for the first time, discovered the genes that play a role in ovarian reserve. This makes choosing the most appropriate medication for the patient’s genetic make-up possible, thus optimising ovarian response.

A more reliable means of detecting anti-Müllerian hormone and evaluating ovarian reserve

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. […]

Techniques for obtaining spermatozoa

There are currently many different solutions when spermatozoa are not present in ejaculate. Access to a trained urologist increases chances of achieving spermatozoa in greater quantities and with improved quality.
What is TESA (Testicular Sperm Aspiration)?
This is a question which many couples ask themselves as they turn to assisted reproduction treatment when the issue is an absence of spermatozoa in semen (azoospermia) with the aim of obtaining sperm. TESA (Testicular Sperm Aspiration) is a technique used for obtaining spermatozoa by testicular puncture.
Modern-day urology means that spermatozoa can be obtained for use in assisted reproduction techniques using different means. Over the last 10 years, we have improved the chances of achieving good results whilst reducing the invasive nature of the process and improving the quality of samples obtained in cases in which this was not previously possible. Men who have undergone a vasectomy, cases in which the sperm duct is obstructed or patients with cystic fibrosis are common examples in which adequate spermatozoa may be obtained through a simple testicular puncture under local anaesthetic. Different types of biopsy are also prescribed in certain cases. The differences between them are as follows: […]

Ovarian stimulation: What is it? Are there any risks involved?

During the first few days of a period, a complex process takes place in the ovaries. The first step is to gather and initiate development in several follicles that contain eggs. Following this, only one egg is selected and it then develops. A mature egg is released during ovulation.

Cryopreserved embryos: Does biobank storage time affect their subsequent viability?

It has been almost 30 years since the first pregnancy from cryopreserved embryos was achieved (Trounson and Mohr, 1983). Ever since then, numbers have been steadily growing at biobanks in assisted reproduction centres, mainly due to the optimisation of reproductive treatments. Our goal is to retrieve a satisfactory amount of good quality embryos (one that is enough for a fresh transfer and also for cryopreservation) by means of an ovarian stimulation cycle. These embryos may be used for future pregnancy attempts, although couples can choose to donate them for reproductive purposes, assign them to specific research projects or dispose of them. Yet, general evidence shows that many couples, mainly those that achieve pregnancy in their first fresh attempt, choose to keep them frozen without a specific end or plan in mind for the future. […]

Instituto Bernabeu strengthens is position as a European reference in matters of R&D at the Annual Congress of the British Fertility Society.

The British Fertility Society (BSF) Annual Congress, one of Europe’s leading fertility and assisted reproduction events, was held on 7th and 8th January in Newcastle (UK). Its scientific committee accepted a total of 11 pieces of research work prepared by Instituto Bernabeu (Alicante) as part of the group’s main lines of R&D. These include poor ovarian response – a pathology which is largely associated with attempts to fall pregnant later on in life –  embryo implantation failure and the impact of genetics on reproduction issues.
