Objective: To analyse the influence of the contraceptive treatment on bone mass. Design: Literary review. Setting: Department of Gynaecology and Obstetrics, 1th Faculty of Medicine, Charles University, Prague, Czech Republic. Method: Informations were collected from fulltexts which were taken from database Medline. Results and conclusion: The lowering of bone turnover under combinated oral contraception was shown in all studies. It is favourable for bone mineral density after 30 years when bone loss starts. The positive influence is significantly dependent on the length of treatment. Only gestagen drugs have no positive efect on bone mass. The influence of contraception on mineral density in term of fysiological bone density increasing before 20-25 year is not clear. Some of studies informed us about adverse efects of extremely-low dose oral contraception on mineral density in this group.
