Number of sterilisations continues to decrease
According to the THL’s register on sterilisations, the total number of sterilisations in 2025 was approximately 2200 which was 6.6 per cent less than in 2024. Women sterilised are on average younger than men sterilised: in 2025, the mean age for women was 37.5 years and the mean age for men 41.5 years.
The proportion of male sterilisations has increased considerably during the 2000s. In 2000, only 17 per cent of all sterilisations were performed to men while in 2025 the share was 70 per cent.
The decrease in the number of sterilisations after mid-1990’s can be attributed to, for example, an expanding range of contraceptives and postponing parenthood. The increase in the number of sterilisations after year 1985 is explained by the updated, more liberal legislation.
For the 2025 data there are some known data quality issues for some hospitals, but the total number of procedures is in line with the data in the Hospital Care Register. However, the register coverage should be treated with caution.
