High-dose dienogest (20 mg/day) was used for the treatment of endometriosis in women aged 18-52 years after laparoscopic and histological diagnosis of endometriosis and staging according to the revised American Fertility Society criteria. T…
In a double-blind, controlled, randomized, four-arm, bicentric clinical study, the effect of four oral contraceptives (OCs) on thyroid hormone parameters, cortisol, aldosterone, endothelin-1 and angiotensin II was investigated. Four groups …
In a double-blind, controlled, randomized, four-arm, bicentric clinical study, the effect of four oral contraceptives (OCs) on lipid metabolism was investigated. Four groups composed of 25 volunteers each (mean age 26.1 +/- 4.5 years; body …
AIM OF THE STUDY: Influence of two hormonal therapies (GnRH agonist--leuprolein acetate and a new progestin--dienogest) on symptoms of endometriosis in patients with different clinical grade of disease. MATERIAL AND METHODS: 34 women with e…
The effects of two oral contraceptive combinations, dienogest 2.0 mg plus ethinyl estradiol 0.03 mg (Valette) and desogestrel 0.15 mg plus ethinyl estradiol 0.02 mg (Lovelle), on the human immune system were compared over one treatment cycl…
Studies have been undertaken to investigate the modulatory effects of a combination of 30 μg ethinylestradiol and 2.00 mg dienogest (Valette®) on ovarian function and on the hemostatic system. Modulation of ovarian function was investigated…
Dienogest is the first non-alkylated 19-norprogestin on the market. This so-called hybrid progestin combines the typical qualities of the modern 19-norprogestins with those of natural progesterone and synthetic hydroxyprogesterone derivativ…
The strong hepatic estrogenic actions of ethinylestradiol (EE) are very likely to be the cause of the cardiovascular morbidity related to the use of combined oral contraceptives (COCs). This survey presents results of EE replacement in COCs…
Forty healthy female volunteers aged between 19 and 35 years (27.3 +/- 4.1 years) with normal menstrual cycles were included in a double-blind, randomized, placebo-controlled study to investigate the influence on the hemostatic system of an…
Antiandrogens or progestins with an antiandrogenic component usually have only a weak antigonadotropic activity. It is thus possible that the antiandrogenic effect on the cellular level is cancelled or at least reduced by an increased ovari…
Twenty-two healthy female volunteers with normal ovulatory cycles, aged between 20 and 34 years (27.3 +/- 4.1), were included in a single-center, noncomparative study to investigate the modulation of ovarian function by an oral contraceptiv…
