Hormonal stimulation

For some patients it is necessary to carry out hormonal stimulation of the ovaries.

  • No ovulation due to an existing hormonal imbalance
  • Reaching an increased pregnancy rate through maturation of more than one oocyte
  • As a part of a treatment with in-vitro fertilization
  • Through hormonal stimulation the ovaries grow, a feeling of pressure occurs in the lower abdomen and the stomach swells.
  • Development of too many follicles and therefore an increased risk of a multiple birth pregnancy: In this case, no unprotected sexual contact should take place and a potential scheduled insemination will not be carried out.
  • Absence of reaction by the ovaries: In this case, it is necessary to stop the therapy and later carry out an attempt with another type of stimulation.
  • In rare cases, it can lead to a so-called ovarian hyper stimulation syndrome (OHSS) if the amount of follicles is too high.
  • In extremely rare cases, the hormone treatment can lead to the development of ovarian cysts.

In Soft IVF, also known as “Smart-IVF” or “Mild-IVF”, the hormonal stimulation dosage is reduced. Less follicles are developed, therefore less ovocytes are retrieved and fewer embryos will be created.

Advantages: Less hormones needed for the patient, rarer and fewer side effects, and fewer embryos have to be discarded.

Disadvantages: Lower rate of pregnancy, a too low response by the ovaries causes a termination of the attempt even before the ovum pick-up.

Every patient of the Kinderwunschzentrum receives an injection training on the day we are handing out the first medication. Our nursing staff will instruct you how to administer the medication through the injections. Should you be unsure or confused with the handling of the injections do not try to use them but instead get in touch with us. The 1st injection can, of course, be injected at the Kinderwunschzentrum.

These demonstration videos for the injection of stimulation medication can and should not replace a consultation with a Fertility Expert as well as professional injection training by qualified personnel. Your individual stimulation protocol as well as your specific dosage can only be issued after medical diagnosis and therapy planning!


This video is for injections using the Puregon pen. Your individual dosage (according to your stimulation plan) can be set on the pen! Should your stimulation protocol include the use of the Gonal-F pen you can download the official manual here: Official manual for the Gonal-F Pen


This video is for injections using disposable syringes, for example Orgalutran, Ovitrelle or Decapeptyl. The injections are ready without any preparation!

Watch video:  INJECTION WITH VIAL 1:1 (75 UNITS)

This video is for injections with Merional, Meriofert, Menopur, etc. In this case (dosage of 75 units) only 1 fluid vial will be mixed with 1 powder vial.


This video is for injections with Merional, Meriofert, Menopur, etc. using several vials in order to increase the units. This is the case for 150-450 units.


We kindly ask you to collect the syringes and injection needles in a solid and firmly closed container (e.g. plastic detergent containers). The container can then be handed over to a collection center for hazardous household wastes.
