Bladder Neck Obstruction: Experience and Management in a Sperm Bank

Area of Science:

• Urology
• Reproductive Medicine
• Surgical Outcomes

Background:

• Primary Bladder Neck Obstruction (PBNO) management often involves surgical interventions.
• Transurethral incision of the bladder neck is a common surgical approach.
• This procedure carries a risk of ejaculatory dysfunction, specifically retrograde ejaculation.

Purpose of the Study:

• To evaluate the impact of transurethral incision on anterograde ejaculation.
• To assess changes in semen quality post-surgery for PBNO.
• To provide data for sperm bank management and patient counseling.

Main Methods:

• Retrospective study of 73 patients with PBNO between 2011 and 2020.
• Evaluation of ejaculatory function, semen parameters, and fertility before and after surgery.
• Analysis included sperm count, morphology, volume, and leukocyte concentration.

Main Results:

• Post-surgery, 20% of patients became oligozoospermic, up from 8.2% pre-surgery.
• Significant decreases in total sperm number and increases in abnormal sperm forms were observed.
• 7.7% of patients reported anejaculation, and semen volume decreased in some cases.

Conclusions:

• Transurethral incision for PBNO can negatively affect semen parameters and ejaculatory function.
• The risk of altered fertility and anejaculation warrants consideration.
• Sperm cryopreservation prior to surgery is advisable for patients desiring future fertility.
