Competence Network: IVF-Naturelle® Your gentle way to having a baby

Dear Readers,

The wish to undergo milder infertility treatments has prompted us to develop the so-called “IVF-Naturelle®” technique, a special form of in vitro fertilization. We largely refrain from using hormone stimulation because the natural cycle produces better embryos and is more beneficial to women's health, and probably that of the children. We are a network of centres who specialize in IVF-Naturelle® and are constantly further developing it.

Prof. Michael von Wolff & the teams in Switzerland, Germany, Austria, Italy and Spain are looking forward to meeting you.

Gambling is legal in New Zealand, but you should be careful when gambling online. The Gambling Act 2003 outlines four categories of online gambling. The Private Wagering Class focuses on individuals providing wagers in a private setting. In addition, players cannot place wagers for prizes that exceed $500, nor can they profit from the activity. Underage gambling can result in penalties of $500 per person, and up to five thousand dollars for the organization that is hosting the event.

What is IVF-Naturelle®?

The IVF-Naturelle® Competence Network

The members of the Competence Network carry out IVF-Naturelle® treatments using methods which have been optimized over several years at the University Hospital for Women in Bern. All these member centres have a high level of expertise. The centres have also committed themselves to documenting their treatments in detail and to always reflect upon their work with the centre in Bern to guarantee high quality and constant optimisation. All the centres listed below also carry out all other commonly used fertility and IVF treatments.

Our scientific research

Mikroskop-Untersuchung in einem IVF-Labor.

The technique of IVF in a natural cycle is as old as IVF itself. However, over the last decades, IVF techniques have shifted more towards IVF with high-dose hormone stimulation.

IVF in a largely natural cycle, i.e. IVF-Naturelle® as defined by us, is not commonly used and therefore the procedures and treatment results are only partly understood by many.
