Insights

Testicular germ cell tumor (TGT) surgery can cause andrological issues. Nerve-sparing retroperitoneal lymphadenectomy and partial orchiectomy can preserve function, while semen cryopreservation is recommended before treatment.

Area of Science:

  • Urology
  • Surgical Oncology
  • Andrology

Background:

  • Germ cell tumors of the testis (TGT) necessitate surgical intervention, which can lead to significant andrological complications.
  • Surgical procedures such as orchiectomy and retroperitoneal lymphadenectomy (RPLND) can impair testicular endocrine and exocrine functions, as well as reproductive capabilities.

Purpose of the Study:

  • To review the andrological consequences of TGT surgery.
  • To discuss organ-sparing surgical options and their impact on testicular function.
  • To highlight strategies for mitigating surgical side effects and preserving reproductive health.

Main Methods:

  • Review of surgical outcomes and andrological sequelae in patients with testicular germ cell tumors.
  • Analysis of partial orchiectomy (enucleation) for selected cases to preserve testicular function.
  • Evaluation of nerve-sparing RPLND techniques to minimize complications like retrograde ejaculation.
  • Discussion of adjuvant therapies like radiotherapy and their effects on hormonal function.

Main Results:

  • Bilateral orchiectomy leads to complete suppression of testicular endocrine and exocrine functions.
  • Partial orchiectomy can preserve testicular function with low relapse risk if intraepithelial neoplasia (TIN) is absent.
  • Radiotherapy on residual parenchyma can prevent cancer but may compromise hormonal function.
  • Nerve-sparing RPLND significantly reduces the risk of retrograde ejaculation, though expertise is limited.

Conclusions:

  • Surgical management of TGT requires careful consideration of andrological preservation.
  • Organ-sparing techniques like partial orchiectomy and nerve-sparing RPLND are crucial for maintaining quality of life.
  • Semen cryopreservation remains a vital option for patients undergoing potentially gonadotoxic treatments.

Spermatogenesis01:41

Spermatogenesis

Spermatogenesis is the process by which haploid sperm cells are produced in the male testes. It starts with stem cells located close to the outer rim of seminiferous tubules. These spermatogonial stem cells divide asymmetrically to give rise to additional stem cells (meaning that these structures “self-renew”), as well as sperm progenitors, called spermatocytes. Importantly, this method of asymmetric mitotic division maintains a population of spermatogonial stem cells in the male reproductive...
Testes: Histology01:27

Testes: Histology

A tough, fibrous membrane, the tunica albuginea, covers the testes, extending inward to form fibrous partitions or septa, dividing them into internal compartments called lobules. Each lobule has 1 to 3 tightly coiled seminiferous tubules where sperm production occurs. These tubules merge into a tubular network at the back of the testis, known as the rete testis. It connects to 15 to 20 efferent ductules, leading to the epididymis.
The spermatogenic cells, responsible for producing sperm, are...

Urinary Tract Calculi VI: Surgical Management

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...
Testes: Gross Anatomy01:19

Testes: Gross Anatomy

The testes, also known as testicles, are the male gonads. They are housed within the scrotum, a sac-like structure located beneath the penis. The scrotum's primary role is to regulate the temperature of the testes, which is crucial for sperm production.
Each testis is surrounded by the tunica albuginea, a dense connective tissue layer that provides structural support and protection. This layer is covered by an outer serous membrane called the tunica vaginalis, which helps reduce friction...

Disorders of the Male Reproductive System

Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.
Prostate disorders are another major concern. These conditions can impair urinary flow due to the prostate's location around the urethra. Symptoms...
