Recently, it has been linked to low serum total testosterone (TT) levels by affecting the optimal functioning of the leydig cell via increasing the scrotal temperature. Varicocele repair has been found post-operatively to increase the serum levels of TT. This study looks at the pre and post-subinguinal microsurgical varicocelectomy serum TT levels in male patients with clinical varicocele. <strong>Methods:</strong> The study involved 88 male patients with clinical varicoceles who met the inclusion criteria. These patients after good history taking and physical examination had their serum TT levels measured pre varicocelectomy and 6 months post-subinguinal microsurgical varicocelectomy. The varicoceles were diagnosed by physical examination and use of scrotal color Doppler ultrasonography (US). <strong>Results:</strong> The number of patients with varicocele were 88 males. The mean age of the patients was 33.43 ± 7.82 years. There was isolated left varicocele in 57 (64.8%) patients and bilateral varicocele in 27 (30.7%) patients. Pre varicocelectomy, 61 (69.3%) patients had serum TT of between 100 - 290 nanogram/deciliter (ng/dl) and a mean value of 241 ± 0.91 ng/dl. Post varicocelectomy 56 (63.6%) patients had serum TT in the range of 300 - 490 ng/dl with a mean of 482 ± 2.87 ng/dl, showing a robust significant increase in the serum TT post-operatively (P < 0.001). <strong>Conclusion:</strong> There was statistically significant improvement in the serum TT levels with 55 (79%) patients exhibiting normalization of serum TT levels after subinguinal microsurgical varicocelectomy. 展开更多
