Purpose: The revision of the 2023 Guidelines for the Treatment of Sexually Transmitted Infections (STIs) has been released. Hence, it is necessary to analyze the current status of STI treatments in Korea. Materials and Methods: A questionnaire was distributed to urologists and gynecologists from December 2022 to January 2023 through an online survey program. Three hundred and forty-one urologists and 302 gynecologists responded to the questionnaire. Results: For Neisseria gonorrhea treatment, ceftriaxone 500 mg and 100 mg of doxycycline twice daily for seven days were most preferred by urologists (22.58%). The treatment most preferred by gynecologists (15.23%) was 500 mg of ceftriaxone and 1 g of azithromycin in a single dose. Both urologists and gynecologists generally treat Chlamydia trachomatis according to the treatment guidelines. For treating Mycoplasma genitalium, 29.03% of urologists preferred administering azithro-mycin at 500 mg once daily, followed by 250 mg for four days. In contrast, 33.11% of gynecologists preferred doxycycline 100 mg twice daily for seven days. Conclusions: Most urologists and gynecologists followed the treatments recommended in the 2nd edition of the STI treatment guidelines, revised in 2016. As many treatment regimens have changed because of the recent increase in antibiotic-resistant STIs, there is a need to encourage them to follow the new treatment guidelines.
