“What does this mean for us?”

[← back to the article overview of the series »Success Rate«]

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:

Assessing the chances

[← back to the article overview of the series “Success Rate”]

Couples considering IVF treatment are accompanied by high hopes and expectations towards their treating specialists. During the initial consultation, most of them raise the key question regarding their chances of achieving pregnancy through reproductive technologies.

Predicting the outcome of fertility treatment is always a medical challenge, as there are numerous factors which may influence the individual chances of getting pregnant and giving birth.

“A lot helps a lot?”

The dangers of self-medication in fertility treatment


Icon Image | Photo: Shutterstock

Even the area of reproductive medicine is touched by the commonly held misconception “a lot helps a lot” when it comes to taking medicines. We often encounter situations in which patients undergoing hormonal stimulation (ovarian stimulation) want to increase the prescribed dosage of their own accord, saying they had read something about it and believed that this would be beneficial to a successful outcome, i.e. contribute to improving oocyte maturation.

To start with, I should like to point out that the selection of an optimal stimulation protocol shall be based on the following factors:

Quality in IVF Centers

Application and Relevance of a Quality Management System


Certificate: ISO 9001:2008 | IVF Centers Prof. Zech

“If there’s a way to do it better: find it.”
Thomas A. Edison (1847-1931)

If we interpret this quote by Thomas Edison, the continual pursuit of improvements may (as, for example, in the case of Edison) lead to new inventions or to the improvement of already existing technologies.

It is a matter of finding ways, enabling us to achieve a certain quality standard that is subject to constant review and improvement. This requires an established structure, for example with respect to the workflows in a company.

Here, experts are referring to quality management systems aiming, among other things, at implementing appropriate measures and building up a trusting relationship with customers.

What exactly is meant by this when dealing with the working procedures of an IVF center?

“Sometimes there’s more in the basket and sometimes less “

The number of oocytes in an IVF treatment

The stage of hormonal stimulation (ovarian stimulation) is an exciting time. Daily injections are required and each ultrasound scan is anticipated with great excitement. What our patients want to know is:

“How many follicles can be identified?
Do all the follicles continue to grow?
How many large and probably mature follicles were produced?”

Hormone doses and therapy protocols are determined on an individual basis in order to achieve the best possible outcome.
It is a much earlier point in time that decides how many follicles will develop during the month of therapy in question. Already three months earlier, a group of 30-300 smaller follicles (a so-called cohort) starts to develop.

Terms for Genetic Diagnostic Methods in Fertility Treatment


Icon Image | Photo: Shutterstock

When it comes to genetic analysis in reproductive medicine, there exist a number of commonly heard terms, such as Pre-Implantation Diagnosis (PID), Pre-Implantation Genetic Testing (PGT), Pre-Implantation Genetic Diagnosis (PGD), Pre-Implantation Genetic Screening (PGS).

But how can they be distinguished from one another? Are there any differences between them?

I had been asked these questions during one of our regular fertility-information evenings (→ Locations, dates and contents). In the following text I would like to go into more detail on my answers.

The Precautionary Freezing of Egg Cells

Different Motives – Different Regulations


Icon Image | Photo: Shutterstock

Cutting-edge medical procedures provide women with the opportunity to have some of their oocytes frozen and “stored” as a precautionary measure. This is intended to preserve the positive status quo of their fertility at the time of cryopreservation, which in turn represents an option for achieving a pregnancy using their own “younger” oocytes in a future IVF cycle.

The underlying motives can be of both of a sociological nature, as well as of a medical nature. Statutory provisions do not exist to the same extent for both aforementioned aspects.

Thus, for example, there are countries where this procedure can be carried out only if medically indicated, for example in patients undergoing chemotherapy which may have a major damaging impact on their oocytes.

When the path to parenthood is “blocked”

Therapy options in connection with the treatment of blocked/damaged fallopian tubes


Icon Image | Photo: Shutterstock

Blocked or damaged fallopian tubes are among the main causes of unwanted childlessness and are seen as classical indications for IVF treatment (“In vitro fertilization”).
Tubal damage is frequently associated with the accumulation of serous, inflammatory or post-inflammatory fluids. We are referring here to a condition called hydro- or sactosalpinx.

What are the possible implications of this concomitant phenomenon and what therapy options are available?

Genetics in reproductive medicine

Background and Significance

by | Published on 14. April 2016, in Treatment.

Genetic disorders may cause severe diseases in humans and are known to have adverse effects on fertility, which may even lead to miscarriages. A closer look into these genetic disorders suggests that there are two main reasons for this:
Chromosomal disorders and gene mutations.

In chromosomal disorders, a distinction is made between numerical anomalies (changes in chromosome number – aneuploidy) and structural anomalies (changes in chromosome structure – e.g. translocations). According to experts, these chromosomal alterations are responsible for around half of all spontaneous miscarriages.

Gene mutations involve changes to the genetic makeup of a single gene, gene segment or several genes, resulting in so-called monogenetic or polygenetic diseases. One of the best-known examples of such a disease is cystic fibrosis – also known as mucoviscidosis – which is the most common inherited monogenic disease in Western Europe.

The linking of reproductive medicine and genetics is thus becoming more and more important. In this respect, it is worth mentioning the well-known term Pre-Implantation Genetic Diagnosis (PGD).

Myths vs. facts of male sexuality

My previous blog post (→ “From Venus to Casanova all the way to Marilyn Monroe…”) has dealt with sexual myths from their beginnings right up to the present day. Against this background, I would like to pursue the following questions on the basis of two examples:

What are the myths on male sexuality that still persist today?

Can current scientific research help us confirm or deny these myths?
