Objective: To determine the value of the gonadotrophin-releasing hormone (GnRH) test in selecting which infertile patients with varicocele would benefit from varicocelectomy.
Patients, Subjects And Methods: The study comprised 30 patients with varicocele who presented between November 1993 and May 1994, and 10 control subjects. The basal serum level of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) were determined and all participants given 100 micrograms of GnRH nasally. The levels of FSH and LH were then determined for up to 2 h. The patients then underwent varicolectomy and the response was evaluated by comparing sperm quality before and after treatment and between those with increased or normal FSH and LH levels in response to the GnRH test.
Results: Those patients who had increased FSH and LH levels after the GnRH test had a mean 121% increase in sperm density (P < 0.001), a 23% increase in sperm motility (P < 0.001) and a 40% decrease in sperm abnormality (P < 0.05). The respective values for those with normal levels of FSH and LH were 15% (P < 0.05), 11% (P > 0.05) and 11% (P > 0.05).
Conclusion: The GnRH test is useful for determining those patients who should benefit from varicocelectomy.

Background: Varicocele (Vx) which is the most treatable cause of male infertility, is also associated with low sperm count, decreased sperm motility and increased sperm abnormal morphology. We aimed in the current study to evaluate the correlation between seminal α-Glycerylphosphorylcholine (αGPC) and semen parameters in infertile patients pre- and post- sub-inguinal micro-varicocelectomy.
Methods: The current comparative prospective study was carried out on 20 male patients who presented to Kasr Al-Ainy Hospitals from March 2022 to March 2023 as well as 20 healthy controls.

Background: Hemodynamic alterations in the spermatic vein are implicated in infertility among patients with varicocele (VC). Contrast-enhanced ultrasound (CEUS), a powerful tool for hemodynamic analysis, remains unexplored for VC. This study aimed to demonstrate the feasibility of using CEUS to evaluate spermatic vein hemodynamics in patients with VC and establish a clear correlation between specific hemodynamic patterns and impaired semen parameters.

Introduction: Varicocele has a detrimental effect on testicular growth and spermatogenesis, hence the importance of its management. This management remains controversial among Tunisian urologists; diagnostic and therapeutic choices tend to vary from one urologist to another.
Aim: The aim of this survey is to evaluate the practices of Tunisian urologists regarding varicocele management compared to the latest international guidelines.

Introduction: Vital dyes lymphography during laparoscopic varicocelectomy (LV) has been suggested to allow for lymphatic mapping thereby allowing for lymphatic sparing (LS) and subsequent reduction of hydrocele formation. Intratesticular injection of the dye seems to achieve the best lymphatic visualization, however, the potential toxicity of some agents, is a cause of concern for the risk of testicular pathological changes. We report our experience with LV, to test the hypothesis that Intraoperative lymphography with methylene blue (BL), is safe and reduces the rate of post-operative hydrocelectomy.

Objective: To evaluate the effects of age on semen and hormonal parameters following microsurgical varicocelectomy among patients with grade 3 varicocele, and to compare fertility outcomes between younger (<40 years) and older (≥40 years) men.
Methods: Retrospective cohort study of infertile patients with clinical left grade 3 varicocele who underwent microsurgical subinguinal varicocelectomy (MV). Patients meeting the inclusion criteria ( = 550) were divided into two groups based on their age at the time of MV: <40 ( = 441) and ≥40 years ( = 109).
