“It is NOT in my blood…”


Icon Image | Photo: Shutterstock

The saying “It is in my blood“ usually refers to character traits that are inborn or inherited and/or correspond to our “inner nature”.
Again and again, scientific findings in the field of genetics have been highly praised by the media – including a study from 2011 which assumed that women with blood group 0 have a two-fold greater risk of diminished ovarian reserve compared to women with blood group A or AB. Serum FSH level tests served as the basis for fertility assessment.

Does this mean that women with blood group 0 have to worry more about their family planning than women with non-0 blood groups?

In order to shed light on this question, we have conducted a retrospective single center study at the IVF Centers Prof. Zech – Salzburg involving 1889 IVF cycles that were analyzed with respect to blood groups and evaluated according to the different age groups (for more details on the respective study, click here). We did not investigate the serum hormone levels but the number of oocytes retrieved during follicular puncture, the mature oocytes (metaphase II oocytes) as well as the fertilization rate and the pregnancy rate.

Mag. Karl-Heinz Brandt(l) | Rene Winsauer(r)

Mr. Brandt, the IVF Centers Prof. Zech offer their patients the possibility to benefit from psychological assistance, if desired.
What does this assistance look like in detail?

Mag. Brandt: The support is geared to issues of particular concern to the couple. These, in a nutshell, are the key issues:

• The fear that a pregnancy test comes back negative for the first time or once again
• Reducing tension during the waiting period
• Disturbances related to the personal surroundings
• A suspected psychological block
• Providing support through hypnosis
• Coming to terms with traumatic experiences relating to pregnancy / birth
• Coming to terms with traumatic experiences encountered during their life, and which are still seen as a burden
• Stresses and strains at the workplace
• Fear of needles and injections

The psychological support itself involves 1-5 sessions, depending on how complex the subject is. To this end, however, there are no fixed rules. We are flexible to determine how best to proceed to meet the requirements of the patients.

In what situations do couples seek your assistance? Read more…

    Ultrasound Scan

    Part 3 of the topic-series »Fertility treatment process«

    Dr Maximilian Murtinger | Medical director
    IVF Centers Prof. Zech Bregenz

    With ultrasound scan you normally associate a pregnancy and the happy parents sharing the first ultrasound pictures of their baby with friends and family. But even before pregnancy occurs, ultrasound diagnostics play a key role, especially in fertility treatment.

    In fertility treatment, ultrasound examinations are performed both during the gynecological assessment of the patient’s medical situation which forms part of the initial consultation and during ovarian stimulation. Ultrasound scanning during ovarian stimulation aims at monitoring the number of growing follicles (prevention of ovarian hyperstimulation syndrome) and precisely determining their size in order to be able to choose the optimal moment to trigger ovulation.

    Ovarian Stimulation

    They are closely associated with human growth and are essential for the metabolism. Human reproduction processes are mainly controlled by them. Hormones: messenger substances, thus playing a crucial role at the beginning of each IVF treatment. Hence, following the initial consultation, the woman provides a decisive boost by undergoing hormone therapy (ovarian stimulation).

    About the background:

    What is the nature of ovarian stimulation?

    Since in the “natural” menstrual cycle of a woman several oocytes start to ripen, on average about 10 follicles (containing the maturing oocytes) compete for dominance each month. Only ONE follicle becomes the so-called dominant follicle containing the mature oocyte. The other follicles stop developing. This is exactly where hormonal stimulation comes into play:
    The woman needs to take appropriate hormone medication (e.g.: gonadotropins = pituitary hormones) in order to induce as many of these follicles – that would otherwise loose the battle for dominance – to grow further and produce a mature oocyte. This requires a targeted and exactly timed approach. Read more…

    The moment of the first conversation


    Icon Image | Photo: Shutterstock

    How many times have we discussed this matter? Countless nights were spent browsing the internet to learn about the experiences of other couples facing involuntary childlessness. But now it is time to take charge of one’s own luck and to realize one’s life’s dream. The decision is made: Tomorrow I am going to call the IVF Centers Prof. Zech in order to arrange an appointment.

    Holding our breath, our fingers are slowly running over the telephone keys. While dialing the number and listening to the dialing tone, our thoughts wander off in all directions: the last pregnancy test that came back negative, the many sleepless nights, a sudden burst into tears, the failed attempts, the hormone injections and how confident we were about a positive outcome. And then there’s the savings, all the sacrifices we had to make, the decision to forego holidays and travelling, overtime hours in the office…My thoughts are somersaulting in my mind and I have a queasy feeling in the stomach when a friendly voice answers the phone.

    Blastocyst Culture

    How treatment methods may help to make the dream of having a child come true



    Involuntary childlessness today is no longer an inevitable fate, thanks to a wide range of treatment methods. This variety includes different approaches in terms of their efficiency which, from the perspective of the respective physicians, biologists and experts, undoubtedly also play a role here. However, from a scientific point of view, it is important to take a very critical look at them. This also applies to one of the most essential points with respect to IVF treatment, namely assessing the development potential of growing embryos.

    Due to our competence that is based on over three decades of experience in successfully performing assisted reproductive techniques, we are able to identify efficient methods and, more than anything, to safely use these methods. Since 1996, we have established at our IVF Center in Bregenz an IVF technique known as blastocyst culture (extended culture up to the 5th day of embryonic development) as the method of choice in order to improve pregnancy rates (first systematic blastocyst culture worldwide).

    For years in the “Champions League of IVF”

    Setting benchmarks in fertility treatment…

    …Prof. Herbert Zech in a detailed interview in our Fertility-Treatment-BLOG:

    Professor Zech, already 29 years ago you have been on everyone’s lips in Vorarlberg, South Tyrol, Switzerland and Southern Germany after having achieved the first pregnancies following IVF treatment. What has happened since then?

    Prof. Herbert Zech

    Prof. Dr Herbert Zech

    It is true that since I have started my medical work, we have been successfully performing fertility treatment first at the University of Innsbruck (1981-1983), and then, since the end of 1984 in Bregenz. The key factor in this success was, above all, our tremendous commitment and hard work. At that time there was no possibility to monitor and trigger ovulation by drug treatment in order to allow egg retrieval to be performed at a specific moment.
    We therefore needed to rely on the “natural” onset of ovulation, which in turn meant that we had to work almost round-the-clock. To this end, we also performed egg retrieval during night time, for instance after midnight or in the morning around five so as to create optimal conditions to achieve a pregnancy.
    And this is how we achieved the birth of the first “test-tube-babies” in Austria – 1983 in Tyrol and 1985 in Vorarlberg. At that time, this was a real sensation, and of course there was considerable press interest in the issue.

    “Using science to overcome infertility”

    How to correctly assess embryonic development

    “After my wife’s oocytes had been fertilized by my sperm and some of the impregnated ova have developed into embryos, we now want to know which embryo is the one most suitable for being transferred to the uterus and what our chances are to achieve a pregnancy and the birth of a healthy child.“

    What matters most to these intended parents – and what they share in common with many others – is that they want to know more about the development of their embryos. Embryo formation is probably one of the most important steps in the course of an IVF treatment. In order to evaluate the developmental potential of embryos prior to performing embryo transfer, the professional knowledge of experienced biologists is needed. Such assessment can be supported by using an assistive tool – the so-called “Time-Lapse Analysis”, which allows for monitoring embryonic development by means of time-lapse imaging using a special camera system (e.g. EmbryoScope). Subsequently, the embryo with the highest implantation potential (Single-Embryo-Transfer) is to be determined on the basis of pre-established criteria. This approach, of course, raises some questions:

    Could it happen that embryos whose early development has to be regarded as suboptimal are nevertheless able to result in pregnancy and the birth of a healthy baby?

    Moreover, can it be justified that instead of transferring these embryos, the focus is put on the success of a subsequent future IVF cycle – an attempt with an uncertain outcome?

    To answer these questions, a study was carried out. The results have been published in the renowned scientific journal RBM Online. The study shows how important it is to do research in this field of reproductive medicine. Read more…
