Context: ceremonies include the Ndut (rite of passage) Link Information: There are two main types of Ndut initiation rites. The first concerns the circumcision for Serer boys whilst the second concerns the initiation of Serer girls. Serer religion and culture forbids the circumcision of Serer girls (female genital mutilation). Only Serer boys are circumcised. Serer girls receive their initiation through njam or ndom (the tattooing of the gums). Preparation for the initiation starts early in childhood. In many cases, boys are circumcised when they reach 13 years old. However it is not uncommon for some to be circumcised when they are 19 to 26 years old. Likewise, Serer girls receive their initiation when they are 11 to 18 years. Answer: the circumcision for Serer boys
