Aim: To investigate whether intramuscular B12 treatment has an effect on ejaculation in male patients with B12 deficiency. Methods: Male patients who were diagnosed with vitamin B12 deficiency in the internal medicine outpatient clinic between October 2024 and March 2025 and started intramuscular B12 treatment were included in the study. The scores obtained from the self-estimated intravaginal ejaculation latency time (IELT), premature ejaculation diagnostic tool (PEDT) and premature ejaculation profile (PEP) questionnaires reflecting the ejaculatory status of these patients before treatment were recorded. After 3 months of treatment, these scores were re-recorded by phone call. The scores recorded before and after treatment were compared. Results: The study included 54 patients. The mean age of the patients was 43.46±13.3 years, mean pretreatment IELT was 2.4±1.4 min, and mean pre-treatment PEDT score was 11.3±4.8. In both the whole patient group and the premature ejaculation (PE) group, a statistically significant difference was observed in the items of perceived control over ejaculation, satisfaction with sexual intercourse and interpersonal difficulty related to ejaculation from the PEP questionnaire form after treatment, no significant change was found in the item of personal distress related to ejaculation. PEDT scores showed statistically significant improvement after treatment both in the whole patient group and in the PE group. In terms of IELT, no differences was observed in the whole patient group after treatment, whereas statistically significant improvement was observed in the PE group. Conclusion: Intramuscular vitamin B12 may improve ejaculation times and satisfaction levels in patient's questionnaires forms in male patients.
