Résumé
Serum follicle stimulating hormone [FSH], luteinizing hormone [LH], testosterone and prolactin levels in relation to histopathological appearance were studied in 32 azoospermic men. Histologically, they were classified into four groups; normal[25%], sertoli-cell-only syndrome [28.1%], maturation arrest [25%] and focal tubular atrophy [21.8%]. In azoospermic men with normal histological findings, gonadotropins and testosterone levels were within the normal values. In other groups associated with histological changes, gonadotropins were significantly raised. Testosterone had a significant lower levels than normal in cases of maturation arrest. Prolactin levels were normal in all azoospermic men. These findings suggested the importance of hormonal determination for evaluation and management of male infertility

Two hundred and twelve infertile males [one hundred and six with varicocele and one hundred and six without] were investigated in this work by clinical examination and semen analysis. The results revealed a highly significant decreased in the mean sperm concentration [23.7 +/- 2.30 million/ml]in patients with varicocele compared with those without. However, the mean percentage of abnormal forms [47.7 +/- 7.63] and the immature forms [8.3 +/- 0.81] were significantly increased in patients with varicocele than those without. The highest percentage of abnormal forms of the head was that of the small heads [16.7%], followed by the amorphous forms [10.6%], while the tapering forms constituted [3.7%]
