The effect of testicular seminoma in semen quality.

Although male subfertility has been reported in a variety of malignancies, most notably testicular carcinoma, the literature that refers to semen quality in males with testicular seminoma is very limited. This study was designed to evaluate the effect of testicular seminoma in semen quality and especially in its three main parameters. Semen specimens from 12 men, aged 24-38 years, with testicular seminoma before they underwent orchidectomy and adjuvant radiotherapy to the ipsilateral para-aortic and pelvic lymph nodes, and from 60 fertile men, aged 24-44 years, were studied. The results support the view that testicular seminoma exerts a deleterious effect on spermatogenesis and consequently to the three main parameters of the semen. The mechanism though of the deleterious effect of seminoma on spermatogenesis remains unclear.
