Background: Gestogens have been recommended to have a place in the prevention of threatened miscarriage and spontaneous pregnancy loss during the first 3 months of pregnancy. Certain studies consider that this steroid hormone has genotoxic effect because they directly involved in the change of DNA structure. Objectives: This study aims to investigate the cytogenetic effects of gestogens on peripheral blood lymphocytes of pregnant women, by damaged cells and chromosomal aberrations, as well as evaluate the models for hormonal therapy in vivo. Materials and Methods: Blood sample from 30 women with threatened miscarriage, who received gestogen therapy in the first 3 months, Were taken. Cytogenetic analyses and karyotyping were performed for Each patient Before and after therapy. Results: The numerical chromosomal aberrations which found in blood lymphocytes of women before taking gestogens were 44,XX and 48,XX. The same result was observed after taking gestogens. The percentage levels of structural chromosomal aberrations were ring chromosome (2.06%), chromatid breaks (12.47%), chromatid gaps (1.65%), dicentric (0.55%), acentric chromosome (4.02%), and interchange chromosome (12.5%). Whereas, the abnormalities after treatment with gestogens were ring chromosome (5.31%), chromatid breaks (42.19%), chromatid gaps (20.86%), dicentric (7.50%), acentric chromosome (17.75%), and interchange chromosome (43.97%). Conclusion: Gestogens as hormonal substitute therapy do not induce numerical chromosomal aberrations but have a significant increase of structural chromosomal aberrations Gestogens have genotoxic effects on human lymphocyte chromosomes at wide range of concentrations. So the potential benefits and side effects of it must be weighed up against the deleterious effects.
