Introduction In 2005, the SEC carried out a Conference on Consent (CdC)
on the Updating the clinical handling of the hormonal contraceptives. CdC is a
scientific conference in which different experts expose their works,
synthesizing the existent knowledge based on the best available scientific
evidence, obtained after exhaustive study of the same. This exposition is
followed by a democratic debate, in which each participant (experts, jury and
invited public) can express their opinion. It is concluded with a resolution in
which the jury (qualified and multidisciplinary) establish the recommendations
in an independent objective way. In this communications the results from the CdC
relating to the contraception with only gestagen methods (MSG) are submitted.
Methodology A total of 750 bibliographic references published between 1995 and
2005, in medical and scientific magazines of contrasted quality and scientific
rigor, and documents (clinical practice guides, standards, reports, …)
published by the professional societies, agencies for the evaluation of sanitary
technologies, government agencies and other scientific entities were analyzed.
Results All the MSG have a high effectiveness, with a Pearl index lower than
the unit. According to the evidence, the MSG are considered having high security.
They have less contraindications than the contraceptive hormonal cocktails. The
criteria for the choice in the contraception of only gestagen are women who wish
hormonal contraception and who, duly informed, accept the pattern of
characteristic bleeding of this contraception. These conclusions are applicable
to the methods of only gestagen (MSG), both oral and intra-uterine, subcutaneous
implants or injectable methods, obtaining a high degree of execution and
continuity of those methods whose use does not depend directly on the users.
