Purpose: Persistent post-treatment genital hypoesthesia (PPTGH) is a primary symptom of post-SSRI sexual dysfunction (PSSD), an iatrogenic syndrome characterized by enduring sexual dysfunction following the discontinuation of some antidepressants. We aimed to estimate the frequency of PPTGH among past users of psychiatric treatments, particularly antidepressants.
Methods: We used a subsample of UnACoRN, a US/Canada survey of sexual and gender minority youth aged 15 to 29. We included participants with a history of psychiatric drug use. We excluded individuals with genital surgeries or without sexual experience. The analysis involved chi-square tests for initial group comparisons, post hoc tests for multiple comparisons, and logistic regression among those who had stopped taking medication. We exponentiated the regression to estimate the odds of PPTGH by drug type, adjusting for age, sex-assigned-at-birth, hormone treatment, and depression severity in three nested models.
Results: 574 of 2179 survey participants reported genital hypoesthesia. They were older and more likely to report male sex assignment at birth, hormonal therapy history, and psychiatric drug history. The frequency of PPTGH among antidepressant users was 13.2% (93/707) compared to 0.9% (1/102) among users of other medications; adjusted odds ratio: 14.2 (95% CI: 2.92 to 257).
Conclusion: Antidepressant discontinuation is strongly associated with PPTGH in the US and Canada where SSRI/SNRI medications account for 80% of antidepressant prescriptions. We call for standardized international warnings and transparent, informed consent. Future research should expand upon our efforts to estimate the risk of PSSD by including all the proposed diagnostic criteria, including documentation of temporal changes in PSSD-related symptoms before and after treatment (≥3 months).

This study explored the long-lasting sexual side effects—specifically, reduced genital sensitivity—of certain antidepressants, even after stopping the medication, in a diverse group of young people, primarily those identifying as sexual and gender minorities. We analyzed responses from a large survey, focusing on participants with a history of psychiatric drug use but without genital surgeries. Our findings indicate that those who used antidepressants experienced a substantial increase in reports of reduced genital sensitivity—13.2% of antidepressant users compared to 0.9% of users of other medications. This symptom is more common among individuals who had used antidepressants and sedatives. Our results emphasize the necessity for clear warnings and proper consent processes about potential long-term sexual side effects, particularly for young patients, and standardization of these procedures across countries. Further research is needed to explore this condition more deeply, including studies of all related symptoms and their development over time before and after treatment.
