Varicocele is the most common and surgically correctible cause of male infertility in men attending to infertility clinics. Infertility affects 15% of all couples and male factor is the primary or contributing cause in 40% to 60% of cases. Varicocele has been shown to cause male infertility in about

In order to detect the varicocele, scrotal scintigraphies by using 99mTc-HSA-D were performed in 14 patients with male infertile or palpable mass in left scrotum on physical examinations. Abnormal pooling of 99mTc-HSA-D, indicative of varicocele lesion, could be found in left scrotum in 9 cases,

Scrotal scintigraphy using a gamma-camera and 740 MBq of 99mTc-labeled human serum albumin was performed on 43 patients with suspected varicocele. In 39 patients (37 left-sided, 2 bilateral) with proven varicoceles, sensitivities by the static and dynamic images were 92.3% and 51.3%, respectively.

Varicocele is the most frequent cause of male subfertility. Several invasive and noninvasive techniques can be used to visualize scrotal phlebectasies. In this study sequential scintigraphy after intravenous injection of 99mTc-albumin was compared with tele-thermography. The normal and pathological

Several theories have been advanced to explain the mechanisms by which varicocele impairs male fertility. These theories include scrotal hyperthermia, retrograde flow of adrenal or renal metabolites, Leydig cell dysfunction and hypoxia. Varicocele is reported to be associated with elevated reactive

BACKGROUND
Varicocele is characterized by abnormal tortuosity and dilatation of the veins of the pampiniform plexus within the spermatic cord and is one of the causes of male infertility. This study aimed to evaluate the differences in biochemical markers and body mass index (BMI) between patients

OBJECTIVE
Living donor kidney transplantation (LDKT) yields the best results of all renal replacement therapies in terms of patient and graft survival. It is the main method in many countries because of worsening patient outcomes due to the accumulation of aged patients with long periods on dialysis
