title: [Our experience with the use of the new Bulgarian intrauterine contraceptive device, the Venus Cu 300 (preliminary report)].
abstract: A team of the family planning centre at the Research Institute of Obstetrics and Gynecology carried out a trial on a new Bulgarian intrauterine contraceptive device (ICD), produced by the firm Venus in the town of Varna: Venus Cu 300. This is a T-shaped device with horizontal arm of 30 mm, vertical arm of 34 mm, a copper thread with an area of 300 mm2 and two control threads. It is produced from PVC. Purity of copper is over 99.9% in the copper thread. The construction of Venus Cu 300 has the positive properties of other intrauterine contraceptive devices, used in our country during the last 15 years. 87 women have been followed in 320 cycles for a period of 6 months. A larger part of them are parous, mainly with one or two children. Venus Cu 300 has been used in seven nulliparas, presenting risk for frequent abortions. Three Venus Cu 300 have been placed immediately after abortion. No pregnancy occurs, which is explained by the careful choice of the patients. Extraction of ICD has been made only in one case due to medical causes: bleeding and pain. More abundant menstruation after ICD has been found in 11.5% of women, but there has been no need to extract ICD. Inferences are made that Venus Cu 300 is in every way equal to the known models of ICD, that the trial should include a larger group of women to accumulate data in dynamics, in order to improve Venus Cu 300 eventually.
