Introduction

Sexuality is an important aspect of human life, and an active sex life would require normal mobility and functions of the lumbar spine. The effect of symptomatic lumbar disc herniation (LDH) on male sexual function is rarely researched.

Methods

Sexually active male patients (n=22, 40.8±6.8 years) admitted for microdiscectomy, were evaluated with a questionnaire for assessing sexual function before and 8 weeks after the surgery. The questionnaire included ODI, Hospital Anxiety Depression Score, Brief Sexual Function Inventory (BSFI), and questions regarding perceived sexual dysfunction (frequency, performance and satisfaction).

Results

The average pre-operative VAS score for back pain was 4.36±2.59 (n=18), and leg pain was 6.81±2.1 (n=22). The mean pre-op BSFI score was 27.8±11.2. Among the five components of BSFI, sexual drive was reduced in 63%, while erection and ejaculation were affected in 40.9% and 31.8% respectively. The VAS score for back pain had a negative correlation with pre-op BSFI score (p<0.03). After the onset of LDH, 12/22 (54.5%) patients noted decrease in the frequency and 17/22 (77.2%) described decrease in the desire/ satisfaction. At 8 weeks post-surgery, the mean BSFI score improved significantly to 33.23 (p=0.002). Sexual drive was normal in 77.7%, while erection and ejaculation were normal in 77.7% and 91% respectively. 59.1% (13/22) had resumed sexual intercourse within 6 weeks of surgery.

Conclusion

LDH resulted in sexual dysfunction in up to 77% of patients, which improved significantly after surgery. By six weeks, majority resumed sexual activity without undue discomfort. The study would help to counsel patients with LDH about sexual function effectively.
