When it comes to choosing an IVF center, most people´s decisions are based on the pregnancy rate obtained by the center in question. This is quite understandable. However, one should be careful not to rely on one single success parameter, but first ask the following question: “What can we expect from the IVF center of our choice?”

This means that certain requirements pertaining to the IVF center need to be clarified in advance, thus ensuring that the treatment provided is suitable to bring about a successful pregnancy outcome.

Prof. Dr. Herbert Zech, an experienced physician and founder of the IVF centers of the same name, answers to the most commonly asked questions by couples seeking fertility support. Artikel lesen

IVF treatment with PGD/PGS might be an option for infertile couples who, despite all efforts, have still not become pregnant and whose diagnostic findings seem to be linked to the failure. However, the option is only available for couples who meet all the medical and legal requirements.

Basically, there are two terms for the aforementioned investigations, though referring to two distinct techniques (for more details see “links”). On the one hand, there is “Pre-Implantation Genetic Diagnosis” (PGD) – in German-speaking countries also referred to as “Pre-Implantation Diagnosis” (PID). On the other hand, there is “Pre-Implantation Genetic Screening” (PGS). These are analytic diagnostic procedures that may, for instance, be used in cases of individuals who are known carriers of a genetic disorder and/or have a history of a genetic disease in the family, recurrent miscarriage or multiple failed IVF attempts.

This underlines the importance of ensuring comprehensive consulting and clarification of the couple’s initial situation by an experienced medical specialist. Dr. Maximilian Murtinger, Medical Director of the IVF Centers Prof. Zech – Bregenz, is familiar with the questions that preoccupy the couples concerned: Artikel lesen

“It had finally worked out and I became pregnant with our little ‘polar bear’. Since yesterday, we are the proud parents of a healthy baby girl and we couldn’t be more thrilled.”

In this way or in a very similar one, couples talk about their experiences gained during IVF treatment involving a so-called ‘cryo cycle’. The procedure comprises the initial freezing of the embryo (fertilized oocyte in the early stages of its embryonic development) in order to thaw it at a later point in time and transfer it to the uterus (embryo transfer).

But why does the attending doctor opt for this kind of therapy? Artikel lesen

The aim of this medical specialty can already be inferred from the term Reproductive Medicine. It means understanding and copying nature right down to the smallest details, i.e. supporting human procreation using medical-technical procedures designed to help sub-fertile couples. Based on current scientific knowledge, an important role is played by a treatment option called blastocyst culture.

During a thorough medical consultation at the beginning of each fertility treatment, the doctor, together with the couple, will decide on the most suitable form of treatment, based on laboratory results, diagnostic findings etc. Details on the medical indication, legal framework conditions as well as on the sequence of the treatment will also be taken into account during this consultation.

There are a variety of reasons why couples may want to use donated eggs to fulfil their dream of having a child. There are situations where couples cannot achieve a successful pregnancy with the woman’s own oocytes (e.g. cancer treatment, genetic diseases, premature menopause) and may therefore decide to try for conception with donor eggs and IVF.

First, however, each couple’s initial situation has to be assessed in a professional and comprehensive way and any questions the couple may have must be answered. MUDr. Libor Hradecký Ph.D., the Medical Director of the IVF Centers Prof. Zech in the Czech Republic, for instance, would be pleased to welcome you in Pilsen and provide you with detailed consultation. For 15 years now, he and his Pilsen-based team have helped couples realize their dream of having a child through donor egg IVF.

As an experienced practitioner of reproductive medicine, he is well aware of the questions preying on the minds of the couples concerned: Artikel lesen

Precisely tailored to the woman’s individual situation, her body is prepared for pregnancy prior to receiving fertility treatment. The ovaries are stimulated with hormones, which is an important first step towards the long-awaited child.

The targeted administration of hormones is intended to induce the maturation of multiple follicles, each containing an oocyte. In medical terms, this kind of treatment is referred to as ovarian stimulation (→ details). Artikel lesen

When analyzing success rates in fertility treatment, it often turns out that the stated values refer to cumulative pregnancy rates. But what exactly is meant by this type of pregnancy rate?

Cumulative is derived from the Latin word “cumulare” (to accumulate).
According to experts, the cumulative pregnancy rate takes account of all pregnancies achieved by IVF following several successive embryo transfers. Irrespective of whether these embryos derive from so-called “fresh cycles” (the fertilized oocyte develops inside an incubator and is usually transferred to the uterus on the fifth day of embryonic development) or from “cryo cycles” (for some reasons, the growing embryo can be frozen/cryopreserved, the frozen-thawed embryo can then be used in a future transfer).

Before and during fertility treatment, patients are often faced with a lot of impressions and information. Sometimes, however, this can be highly confusing, giving rise to a large number of questions.

After asking around, I discussed the issues with Univ. Prof. Dr. Herbert Zech, a specialist in reproductive medicine and founder of the IVF centers of the same name. Below please find his answers to some frequently asked questions:

Sperm-Check using a smartphone app, ovulation tests, testing of hormone levels using ready-to-use test kits …
Fertility tests for self-/home testing are not entirely new, but obviously there are ever more inventive products featuring supposedly greater user friendliness. This, of course, arouses the interest of many men and women.

US researchers have recently presented a prototype of an accessory for smartphones that allows to analyze a semen sample for sperm concentration and motility (according to WHO criteria) using an appropriate App. The goal is to offer a fertility test for men that is simple and reasonably priced in the same way as are pregnancy tests, the scientists say.

But do such tests for men who wish to conceive a child actually provide sufficiently meaningful results? Artikel lesen

When it comes to choosing an IVF center, among other things, couples seeking fertility support want to learn more about the clinic’s performance figures (e.g. pregnancy rate, live birth rate). In some countries, IVF centers are required by law to publish their results and make them freely available. In countries where this is not the case, the disclosure of such data occurs on a voluntary basis. In both cases, for most couples the following question arises when taking a closer look at the outcomes presented:
