For years, varicocele treatment has been a key focus in urology-
andrology due to its high prevalence and significant role in male subfertility and
infertility. Despite extensive research, the etiology, pathogenesis, and treatment
remain debated. A review of 60 sources (11 domestic, 49 foreign) highlights the
need for effective management strategies. Treatment aims to restore reproductive
function, improve fertility, and minimize recurrence and complications.

For many years, the issue of treating patients with varicocele has been at the
center of attention for both domestic and international urologists-andrologists [1].
The results of numerous studies suggest that this condition is highly prevalent in
the male population, shows no tendency toward a decline, and remains one of the
primary causes of subfertility or infertility.
Thus, there is a clear need to explore effective solutions to this pressing
problem. Varicocele is characterized by varicose (grape-like) dilatation of the
veins of the pampiniform plexus of the spermatic cord, accompanied by
intermittent or permanent venous reflux [2]. Varicocele is observed in
approximately 8–20% of the general male population , including 30–40% of men
with primary infertility and 70–81% of those with secondary infertility. The
varicose dilatation of the veins of the spermatic cord and testicular membranes
leads to testicular tissue damage, impaired testicular function , disrupted
spermatogenesis, and subfertility [3]. The established link between varicocele and

infertility has been the main reason for the inclusion of this pathology in programs
developed by the World Health Organization.
The diagnosis of varicocele is based on the patient's medical history and
physical examination . In most cases, the disease is asymptomatic; however,
according to studies by T. Lorenc et al. [4], and S. Pack and W.S. Choi , some
patients may palpate a scrotal mass above the testicle or complain of scrotal
sagging, prolonged pain in the scrotum or groin that worsens with walking,
prolonged standing, or erection, and pulling pain in the testicle along the
spermatic cord and groin area that intensifies when lifting heavy
objects.According to A.D. Tarasko [5], pain syndrome in varicocele is
nonspecific, which necessitates differential diagnosis with other conditions.
To date, the etiology of this condition has been studied and is recognized as
multifactorial
[6].
The prevailing concept considers varicocele not as an
independent disease, but rather as a symptom of a developmental anomaly or
pathology of the inferior vena cava or renal veins.
The extreme variability in the structure of the venous system (including both the
left and right renal veins) is the result of impaired regression of the cardinal and
subcardinal veins. Retrograde blood flow is observed in cases of congenital
(primary) absence of valves in the testicular vein, as well as in genetically
determined weakness of the venous wall due to underdevelopment of the muscular
layer and connective tissue dysplasia, leading to primary valvular insufficiency
[7].
Conclusion:
Varicocele is a multifactorial condition with a high prevalence
among men and a significant impact on male fertility. It is not an isolated disease
but often reflects underlying vascular anomalies, such as congenital valvular
insufficiency or developmental abnormalities of the venous system. Although
frequently asymptomatic, varicocele can impair spermatogenesis and testicular
function, making accurate diagnosis and timely intervention essential. Given its

role in male infertility and demographic implications, continued research and
improved treatment strategies remain critical.
