Abstract
The most difficult form of male infertility to treat is azoospermia. Azoospermia is defined as the complete absence of spermatozoa in the ejaculate. The age of the patients who underwent clinical and diagnostic studies varied between 22 and 45 years. Among 119 examined patients with azoospermia, 58.0% were diagnosed with secretory infertility. In 42.0% patients, the presence of spermatogenesis in excretory-obturational infertility was established. Among 69 patients with secretory infertility, 23 had azoospermia in the absence of spermatozoa and spermatogenic cells, which accounted for 33.3% of all patients with secretory infertility (in particular, 2 with leukocytospermia, which indicated damage to the tubular apparatus as a result of previous orchitis). In 66.6% patients, azoospermia was observed in the absence of spermatozoa, but in the presence of precursor cells of spermatogenesis. 11.5% patients out of 69 (group 1) were diagnosed with concomitant diseases. We see that arterial hypertension, diseases of the gastrointestinal tract, liver, and kidneys occur. Hereditary diseases were not detected in the examined patients. Pain of varying intensity was found in 6.7% of patients, varying degrees of testicular hypoplasia were found in 7.6%, dysuria in 13.4%, epididymitis in history 8.4%; history of epidemic mumps 6.7%; 12.6% had depression, restlessness, sleep disorders, and 21.0% had erectile dysfunction. According to clinical examination and ultrasound, chronic prostatitis is suspected in 19.2% of patients. An increase in the number of leukocytes in the blood was found in 13.2% patients. According to ultrasound, 60.5% of the patients with azoospermia had normal testicular sizes, and 39.5% had reduced testes. The volume of the testicles in the control group was 22.3 ± 2.1 cm³ on average, varying from 18.3 to 25.1 cm³. In the group with azoospermia, the volume of the testicles was on average 16.7 ± 1.7 cm³ and varied from 8.2 to 21.1 cm³, that is, the volume of the testicles in patients with azoospermia was on average 1.3 times smaller compared to normozoospermia. In the obstructive form of azoospermia, diffuse changes were detected in both testicles, probably obturational changes. Hypoplasia of the left testicle and increased echogenicity were observed in the non-obstructive form of azoospermia. The veins of the spermatic cord were moderately dilated. There was a normal amount of free fluid in the scrotum. According to elastography, the elasticity of the testicles was above normal. Obturational processes in the testicles were suspected. The hemodynamic parameters of testicular parenchymal blood flow in infertile men obtained by ultrasound dopplerography are of important diagnostic value. The average value of the linear blood flow velocity in the arteries of the parenchyma in men with normozoospermia was 0.107 ± 0.015 m/s on the right, and 0.103 ± 0.012 m/s on the left. With azoospermia, the average value of the linear velocity of blood flow on the right was 0.086 ± 0.012 m/s, and on the left – 0.084 ± 0.008 m/s. Thus, the hemodynamic indicators of the scrotum show that the most pronounced changes are found in men with azoospermia in the absence of spermatogenesis.

Abstract
Background Secreting interstitial cell (Leydig cell) tumors are rare. In adults, the clinical picture and steroid levels are variable. Case presentation This paper presents a case of left testicular tumor, showing azoospermia with normal serum level of total testosterone, collapsed FSH and LH, and high delta4 androstenedione. Histopathological investigation revealed a Leydig cell tumor. TESE allowed spermatozoa extraction and freezing. Testicular histology found hypospermatogenesis and germ-cell aplasia with interstitial fibrosis. Surgical resection of the tumor resulted in normalization of gonadotropins and fall in serum delta4 androstenedione to subnormal levels in the postoperative period confirming that the tumor was secreting delta4 androstenedione. It was hypothesized that high delta4 androstenedione resulted in intra tumoral 17 β-HSD overtaken by delta4 androstenedione or that 17 β-HSD activity in the tumor was different from that of normal Leydig cells. Three months after surgery sperm analysis found a complete recovery of spermatogenesis. A spontaneous pregnancy occurred 3 months after surgery and a girl was born. Conclusions In this case, the diagnosis of testicular Leydig cell tumor secreting delta4 androstenedione was made in a context of azoospermia.

Abstract
OBJECTIVE To determine the long-term fertility status of patients treated for Leydig cell testicular tumour. MATERIAL AND METHODS [corrected] In a series of 506 testicular tumours observed in the Midi-Pyrenées region between 1980 and 1998, 17 were Leydig cell tumours (3.3%) and constituted the study population. Andrological records were available for all patients. Information concerning fertility before and after orchidectomy was obtained by validated letter questionnaire. All patients completed the questionnaire. RESULTS The mean follow-up was 84 months (range: 36-173). The mean age at diagnosis was 32 years (range: 24-51). The presenting symptom was gynaecomastia in 9 cases (53%), enlarged testis in 4 cases (24%), scrotal pain in 2 cases (12%) and male infertility in 2 cases (12%). Before onset of their disease, 13/17 (76.5%) patients had tried to have a child and 6 (46.2%) had successfully fathered a child. After treatment of their Leydig cell tumour, 10/17 (58.8%) had tried to have a child and 7 (70%) were successful. CONCLUSION The population of men with Leydig cell tumour of the testis is a population with decreased fertility before treatment of the tumour. Resection of the tumour improves this situation, but 3 out of 10 patients remain infertile, indicating the need for semen storage measures in this population.

Abstract
Little is known about the pathogenesis of Leydig cell tumours (LCTs) of the testis. The observation of several associated dysgenetic features in the non-tumoural parenchyma and in the contralateral testes of men with testicular germ cell neoplasms has served as the basis to propose that there may be a common mechanism for different male reproductive disorders. However, the possible relationship between LCTs and other testicular lesions has not been explored. Here we describe the presence of primary lesions in the non-tumoural parenchyma of testes with LCT, from which we try to establish possible pathogenetic associations. We studied the non-tumoural parenchyma adjacent to 16 LCT specimens. Parameters as Leydig cell hyperplasia (LCHY), qualitative evaluation of the germinal epithelium and spermatogenesis, the presence of Sertoli cell-only tubules (SCOT), and the Sertoli cell nuclear morphology were consistently assessed in all cases. SCOT associated with Sertoli cell dysgenetic morphology was the most frequent finding, present in 50% of the cases. Another interesting finding was the presence of LCHY in four cases (25%). Abnormal spermatogenesis was found in 81.25% of the cases, and it consisted of lesions of the adluminal or basal compartments of seminiferous tubules. The occurrence of either dysgenetic Sertoli cells or LCHY adjacent to LCTs could represent primary anomalies, resulting from a common insult also involved in tumourigenesis. The abnormalities in spermatogenesis observed here are likely to represent consequences of either tumour compression or abnormal hormonal production. The significance of these associations merits further investigation regarding a common pathogenesis.

Abstract
CONTEXT Leydig cell tumors (LCTs) are the most common non-germ-cell neoplasms of the testis. LCTs are often hormonally active and can result in precocious virilization or in adult feminization. We identified an LCT in an affected individual from a kindred with hereditary leiomyomatosis and renal cell cancer (HLRCC) and a germline fumarate hydratase (FH) mutation (N64T). OBJECTIVE Our objective was to investigate the role of FH mutations in predisposition to LCTs. DESIGN We tested for pathogenic effects of the N64T mutation and screened an additional 29 unselected adult LCTs for FH alterations. We also tested these LCTs for mutations in two genes, the LH/choriogonadotropin receptor (LHCGR) and the guanine nucleotide-binding protein alpha (GNAS) that had been implicated in LCT tumorigenesis. RESULTS No mutations were found in GNAS, and one tumor had a LHCGR somatic substitution. In addition to the HLRCC case with the N64T germline FH mutation, we identified one other LCT with a previously unreported FH mutation (M411I). Both LCTs from these patients showed loss of the wild-type FH allele. Immunohistochemical and in situ hybridization analyses demonstrated activation of the hypoxia/angiogenesis pathway not only in the tumors belonging to the FH mutation carriers but also in several other mutation-negative LCTs. CONCLUSIONS Our study shows that some LCTs are caused by FH mutations and represents one of the first reports of germline mutations in any type of adult testicular tumor.

Abstract
Leydig cell tumors of the testis are rare, mostly presenting as a testicular mass or as endocrinological symptoms. Here, three patients who were admitted for investigation of primary infertility and one patient presenting with a testicular mass are reported. The histological features were reviewed and an immunohistochemical study was done using a panel of antibodies against cytokeratin, vimentin, inhibin A, S-100, Ki-67, follicle-stimulating hormone, luteinizing hormone, prolactin, p53, bcl-2, and c-erbB2. The latter case (lost during follow up of metastatic disease) demonstrated massive tumor necrosis, extension through the tunica albuginea, and a high mitotic activity and MIB-1 score. Only this malignant case was bcl-2 positive. Of the two oncogenic markers studied, none of the cases were positive for c-erb2, while p53 was positive in more than 50% of cells in the malignant case and in one case of infertility with a large tumor, hemorrhage, focal necrosis and atypical cytological features. We recommend the evaluation of infertile men for Leydig cell tumors, and we believe that a panel of antibodies, including Ki-67, p53 and bcl-2, used for immunohistochemical analysis could be of diagnostic value in the identification of malignant and borderline cases of Leydig cell tumor.

Abstract
Testicular cancers occur at a rate of 2 cases per 100,000 males. Gonadal stromal tumors, including Leydig cell tumors and tumors of the adrenogenital syndrome, account for 1% to 3% of these neoplasms. Despite their rarity, these hormone-producing tumors are particularly interesting because of their potential for causing endocrinologic manifestations in prepubertal and adult males. They are also clinically significant, and early identification is critical to avoid profound and often irreversible developmental changes in affected children. An accurate diagnosis is important to differentiate tumors that will respond to medical management from tumors that require definitive surgical therapy.
