ABSTRACT
Background Infertility affects many couples, with male factors being responsible for over half of the cases. Male infertility can arise from various testicular illnesses, such as varicocele and cryptorchidism, as well as posttesticular disorders, like ejaculation abnormalities. Infertility is defined as the inability to conceive after 12 months of unprotected sexual activity or after six months for women over 35. Diagnostic techniques such as semen analysis and scrotal ultrasonography are done to evaluate conditions like varicocele and epididymo-orchitis. This study aims to assess the diagnostic utility of ultrasonography for male infertility and compare its findings with those from surgery and clinical care. Methodology All patients were referred to the Department of Radiology, Tertiary Care Hospital, South India, for transrectal and scrotal ultrasonography, using a high-frequency transducer with a frequency of 7.5 MHz and a color Doppler when necessary. The study included all male patients with infertility and abnormal semen analysis, as well as those with infertility accompanied by scrotal abnormalities detected during clinical examination. Patients were placed in the left lateral decubitus position for the transrectal ultrasonography examination. The testes and epididymis were thoroughly examined on both sides and compared regarding symmetry, size, texture, and vascularity. Results Varicocele was the most frequent anomaly detected by both clinical examination and ultrasonography. Ultrasound detected 30 cases of varicocele, whereas clinical examination diagnosed 15 cases. Hydrocele was identified in eight cases through clinical examination and in 15 cases through ultrasound. Epididymal cysts were found in five cases via clinical examination, while both clinical examination and ultrasonography discovered epididymitis in 10 cases. Overall, the number of anomalies detected by ultrasound was significantly higher than those found by physical examination, with a statistically significant p value of 0.001. Conclusion Transrectal ultrasound provides high-resolution imaging of the prostate, seminal vesicles, and distal vas deferens, which aids in diagnosing obstructive azoospermia. Imaging is a valuable supplement to clinical examination and laboratory studies for accurately identifying anatomy and abnormalities. Both transrectal and scrotal ultrasonography offer crucial information in diagnosing male infertility. Ultrasonography is more effective in identifying pathological abnormalities than clinical palpation.
