Impact of Acute Lumbar Disk Herniation on Sexual Function in Male Patients

Prospective observational study.

In this study, we determined the effects of lumbar disk herniation (LDH) on male sexual activity and whether surgical intervention improved any related sexual dysfunction.

The impact of surgery on sexual activity has been extensively studied in arthroplasty, uro-gynecological surgery, and stroke, but there are relatively few studies on spine surgery, and none involve an Asian population to the best of our knowledge.

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

The average preoperative Visual Analog Scale (VAS) score was 4.36±2.59 (n=18) for low back pain (LBP) and 6.81±2.1 (n=22) for leg pain. The mean preoperative BSFI score was 27.8±11.2. Among the five BSFI components, sexual drive was reduced in 63.0% of patients, while erection and ejaculation were affected in 40.9% and 31.8%, respectively. The VAS score for LBP had a negative correlation with the preoperative BSFI score (p <0.03). After LDH onset, 54.5% of patients noted a decrease in frequency, and 77.2% described a decrease in desire and satisfaction. At 8 weeks after surgery, the mean BSFI score significantly improved to 33.23 (p =0.002). Sexual drive was normal in 77.7% of patients, and erection and ejaculation were normal in 77.7% and 91.0%, respectively. Overall, 59.1% had resumed sexual intercourse within 6 weeks of surgery.

LDH resulted in sexual dysfunction in up to 77% of patients, which significantly improved after surgery. By 6 weeks, the majority had resumed sexual activity without undue discomfort. Therefore, this study supports counseling for patients with LDH about sexual function.
