    Author: Hausmann L, Goebel KM, Klähn D, Kaffarnik H.
    Journal: Klin Wochenschr; 1975 Sep 15; 53(18):853-60. PubMed ID: 1165627.
    Abstract:
    An ivestigation has been performed in 49 women about the influence exerted on the glucose-tolerance, insulin and proinsulin secretion by hormonal contraceptives of different types and compositions. A disturbed dynamics of the insulin secretion with elevated values in the OGTT at two and three hours has been proven at a nearly equal degree using combined preparations (Anacyclin, Eugynon, Neogynon, Mikrogynon) or sequential preparations (Kombiquens, Ovanon). Though there has been interference with the glucose tolerance, the serum proinsulin in the OGTT showed increased levels too. When a combined preparation was applied, the proinsulin values were significantyl higher compared to a sequential type contraceptive. The observed disturbance of the insulin and proinsulin secretion is explained by a decreased sensitivity to insulin in the peripheral fat tissue. The actual dose of the estrogen-gestagen components has no influence on the described changes. Elevated insulin levels are demonstrable already during the first treatment cycle. The degree of the disturbance is independent of the duration of the medicamentous application during the first 6 contraceptive months. After withdrawal of the respective contraceptive steroid the insulin secretion showed nearly normal dynamics during the subseqeunt menstrual cycle.

The actual dose of the estrogen-gestagen components has no influence on the described changes. Elevated insulin levels are demonstrable during the 1st treatment cycle. The degree of the disturbance is independent of the duration of treatment during the first 6 contraceptive months. After withdrawal of the respective contraceptive steroid the insulin secretion showed nearly normal dynamics during the subsequent menstrual cycle.
