Sex Change
A surgeon in the city of Geffen can change your account's sex at the cost of a GM Service Ticket.
Information
When creating an account, you can choose if your account is male or female. However, if you wish to change to the opposite sex later on, you must meet certain criteria, listed below.
1. Your account must not contain any bard or dancers, their "baby" version, or their transcendent version clown and gypsy.
2. No characters undergoing the bard or dancer job change quest are on the account.
3. High Archers which are set to be Clowns and Gypsies may not be in your account.
Surgeon
If you meet the requirements listed above, simply talk to the Surgeon NPC in Geffen 150, 45, just a few steps east from the fountain. The only cost for this service is 1 GM Service Ticket. These are obtained from the GM Assistant for 150 Vote For Points, from the Monthly Fairy Auction for zeny, by donating 5.00$, or less commonly, from events such as Crazy Merchant and PVP For Items.
