Male Sexual Response: Erection & Ejaculation

Male Sexual Response: Erection & Ejaculation

Sexual stimulation can take various forms, such as physical touch and visual or auditory cues. When this happens, the parasympathetic reflex in the sacral portion of the spinal cord is activated. This reflex stimulates the release of nitric oxide (NO), which then dilates the arterioles in the penis, increasing blood flow to the erectile tissues - the corpora cavernosa and corpus spongiosum.
The blood filling the erectile tissues compresses the veins, which helps to prevent blood from leaving...

Penis

Penis

The penis serves a dual role in sexual reproduction and urination. It consists of three main regions: the glans penis, the body, and the root, each with distinct functions and unique anatomical features.
Anatomy of the Penis
The glans penis, or the head, is the terminal part of the penis and houses the external urethral orifice, the exit point for urine and semen. Covered by the prepuce, or foreskin, the glans is noted for its sensitivity and plays a key role in sexual pleasure. The body of the...

Summary

This summary is machine-generated.

Unilateral nerve grafting after prostatectomy is feasible, with 72% of patients achieving penetration. Most still require PDE-5 inhibitors, but the procedure is well-tolerated.

Area of Science:

Urology
Nerve Grafting
Prostatectomy

Background:

Radical prostatectomy can lead to erectile dysfunction.
Nerve-sparing techniques aim to preserve erectile function.
Nerve interposition grafts are an option for select patients.

Purpose of the Study:

To evaluate the efficacy of unilateral cavernosal nerve grafting after radical prostatectomy.
To assess functional outcomes and patient tolerance.

Main Methods:

Forty patients underwent unilateral nerve grafting with contralateral nerve replacement.
Patient selection based on risk assessment, MRI, and intraoperative findings.
Pre- and post-operative International Index of Erectile Function (IIEF) scores were analyzed.

Main Results:

Median follow-up was 19 months, with a median IIEF score increase of 7.5.
72% of patients reported successful penetration post-surgery.
97% experienced numbness at the graft harvest site; 7% reported pain.

Conclusions:

Unilateral sural nerve grafting is a feasible and well-tolerated option for prostatectomy patients.
While IIEF scores decreased, a majority achieved penetration.
PDE-5 inhibitors remain necessary for intercourse in most cases.
