Does the Himplant Affect Ejaculatory Function?

Introduction

A common concern for men considering penile enhancement with the Himplant is whether the procedure will affect ejaculatory force and volume.

What Does the Anatomy Suggest?

Anatomically speaking, there is no direct reason the procedure should reduce ejaculatory force. The surgery does not involve the prostate, seminal vesicles, bladder neck, pelvic floor or urethra —key structures involved in ejaculation.

What Do Patients Report?

While an assessment of the physiology and anatomy involved in ejaculatory function suggests no significant risk of ejaculatory dysfunction after the procedure, some men do report a reduced force of ejaculation. This is generally a temporary phenomenon, with most patients noting that things return to baseline within a few weeks to months of resumed sexual activity.

Why Does This Happen?

The most common theory—and the one I’ve observed in my own practice—is that:

• Post-operative tension in the penile skin places subtle pressure on the urethra that increases outflow resistance
• As the skin naturally stretches and adjusts to the implant over time, ejaculatory force tends to normalize

What About Long-Term Changes?

There is a small subset of men who report persistent decrease in ejaculatory force even after full healing.

My Hypothesis

While no formal study has yet proven a cause, I believe the issue may stem from:

• Minor nerve disruption to small, understudied fibers that supply the bulbar and penile urethra
• These nerves may influence the pulsatile contractions responsible for forceful ejaculation

Traditionally, the mechanics of ejaculation were thought to be limited to:

• Emission from the seminal vesicles into the urethra
• Bladder neck closure to prevent retrograde ejaculation
• Pelvic floor contractions to expel the semen

However, neuroanatomy and patient experiences suggest there may be more to the story, including subtle contributions from urethral nerve activity that can be affected during the surgery.

Bottom Line

• The vast majority of men experience no long-term changes in ejaculatory function.
• Temporary reductions in force are relatively common and typically self-resolving.
• A small number may notice persistent subtle changes, though these are not harmful, and the overall sexual experience and confidence usually improve dramatically.
• As with all aspects of penile surgery, individual anatomy and healing response vary.
