  • Compound B and other substances described in WO 2008/000521 are used in pharmaceutical preparations for contraception and in therapy for the treatment of premenstrual disorders, such as headache, depressive moods, water retention and astodynia.

  • intrauterine use and the use of the compounds in an intrauterine system (IUS) are not described in WO 2008/000521.
  • oral contraceptives are the most widely used contraceptive method in many countries. Nevertheless, hormone-containing, in particular estrogen-containing contraceptives in the public and the literature due to potential risks (such as a slightly increased risk of thrombosis,
  • the basis for the contraceptive effect of Mirena ® is essentially the thickening of the cervical mucus and the local effect of Levonorgestrels, which leads to a strong antiproliferative effect on the endometrium.
  • levonorgestrel alters the utero-tubal milieu and impairs sperm motility and function.
  • Plasma drug levels of on average by 206 pg / ml 2 Although this value is below that of orally administered levonorgestrel-containing contraceptives, it is still so high that it inhibits ovulation in about 20% of users in the first year of application and the known systemic side effects such as acne, depressive moods, May result in chest pain or decreased libido 3 .
  • Contraceptive methods e.g., hormone level measurement or temperature method
  • mechanical methods e.g., condom or diaphragm

  • the object of the present invention is therefore to provide a contraceptive method which, with comparable high contraceptive safety, as achieved by the known hormone-based contraceptive methods, has even better tolerability.
  • R 6 and R 7 is a hydrogen atom or together an ⁇ -methylene group, namely by the intrauterine application of 18-methyl-15 ⁇ , 16 ⁇ -methylene-19-nor-20-spirox-4-ene-3 or 18-methyl-6a, 7a, 15 ⁇ , 16 ⁇ -dimethylene-19-nor-20-spirox-4-en-3-one.
  • the substances used according to the invention have an at least 10-fold lower androgenic activity compared to LNG.
  • This property compounded with the pronounced dissociation local vs. systemic, shows that no systemic androgenic effects (eg acne) are to be expected even with very high dose local uterine applications compared to levonorgestrel, even if systemic concentrations comparable to levonorgestrel in Mirena ® applications should occur.
  • the substances A and B are excellent for intrauterine use in gynecological therapy but especially in contraception.

  • Active ingredient (B) is preferably in the range between 2-500pg / day, more preferably from 2-200pg / day, in particular from 5-100 g / day, dosed.
