A case of female genital mutilation was discovered every three days, on average, by maternity staff in Wales last year.
New figures obtained by BBC Wales show 123 victims of FGM were found by midwives or maternity doctors in 2016.
A further 44 children under the age of 18 were highlighted as vulnerable to the practice.
Charity Welsh Women’s Aid said figures showed just the “tip of the iceberg”.
Campaigners have previously called for a dedicated clinic to be opened in Walesto help FGM victims.
The statistics, provided by the seven Welsh health boards after a Freedom of Information request by BBC Wales, showed the highest number of cases – 53 – were recorded by Aneurin Bevan health board.
