Natural Cycle


Natural CycleThe natural cycle is a simple method of In Vitro Fertilization, which is performed during the patients’ natural cycle. Occasionally, it is be possible to perform a slight ovarian stimulation in order to obtain 1 - 2 eggs, which will be fertilized in the laboratory.

The embryo culture in a laboratory requires constant surveillance and control of multiple parameters; for this reason in vitro fertilization greatly depends on the quality of the laboratory as well as on the applied assisted reproduction techniques.

Pregnancy rates up to 40%*


Natural Cycles

  • With sperm from partner.
  • With donor sperm.
Spain has one of the most progressive laws on assisted reproduction worldwide. Both sperm and egg donation are legal and anonymous. In addition, Spanish law provides that children born by means of assisted reproduction techniques shall not be able to obtain information regarding the donor - similarly, the donor shall not be able to obtain information, such as the identity of the conceived child.

Spanish law also provides the study and acceptance of donors by establishing specific mandatory tests; however, at IVF Spain we go further than what is required by law to accept, gather and utilise both eggs and sperm with the highest assurance of security.

For whom is it appropriate?

  • Patients between 25 - 40 years.
  • Patients with great expectations of success.
  • Patients with a good ovarian response.
Treatment viability depends on medical diagnosis.


*Pregnancy rates depend on age, ovarian reserve, individual response to treatment and genetics. Displayed data are representative to studied cases.
