Azoospermia is the complete absence of spermatozoa in the ejaculate in two or more semen analyses after centrifugation. Nonobstructive azoospermia (NOA) represents the most severe form of male factor infertility accounting for 10%-15% of cases and stems from an impairment to spermatogenesis. Understanding of the hypothalamic-pituitary-testicular axis has allowed NOA to be subcategorized by anatomic and/or pathophysiologic level. The etiologies of NOA, and therefore, the differential diagnoses when considering NOA as a cause of male factor infertility, can be subcategorized and condensed into several distinct classifications. Etiologies of NOA include primary hypogonadism, secondary hypogonadism, defects in androgen synthesis and/or response, defective spermatogenesis and sperm maturation, or a mixed picture thereof. This review includes up-to-date clinical, diagnostic, cellular, and histologic features pertaining to the multitude of NOA etiologies. This in turn will provide a framework by which physicians practicing infertility can augment their clinical decision-making, patient counseling, thereby improving upon the management of men with NOA.

Except in cases of hypogonadotropic hypogonadism, the use of medical therapy before microsurgical testicular sperm extraction (micro-TESE) is controversial. In some studies, hormone therapy has been shown to improve the possibility of sperm retrieval during micro-TESE and even lead to the presence of sperm in the ejaculate in some cases, thereby obviating the need for micro-TESE. However, their routine use before micro-TESE in cases of nonobstructive azoospermia (NOA) being associated with hypergonadotropic hypogonadism and eugonadism (normogonadotropic condition) has not been supported with robust evidence. In this review, we discuss different types of medical therapy used before micro-TESE for NOA, their risks and benefits, and the available evidence surrounding their use in this setting.

Non-obstructive azoospermia is a common condition associated with significant health risks, including increased mortality, cancer, and chronic diseases such as metabolic and cardiovascular disorders. This review aims to highlight the potential health challenges faced by men with this condition compared to fertile counterparts. Through a comprehensive bibliographic search on PubMed, using the following algorithm: ("infertility, male" [MeSH Terms] OR "azoospermia" [MeSH Terms]) AND ("mortality" [MeSH Terms] OR "neoplasms" [MeSH Terms] OR "chronic disease" [MeSH Terms] OR "diabetes mellitus" [MeSH Terms] OR "heart diseases" [MeSH Terms]), we analyzed existing literature to explore the associations between infertility, specifically azoospermia, and adverse health outcomes. Findings indicate that infertile men are at a higher risk of death, various cancers (particularly testicular cancer), metabolic syndrome, diabetes, hypogonadism, and cardiovascular disease. Although research specifically addressing azoospermia is limited, available studies support the notion that men with this condition may experience heightened health vulnerabilities. Given these risks, it is imperative for healthcare professionals, especially urologists, to conduct thorough health assessments for men diagnosed with azoospermia. Informing patients of these potential health issues and integrating comprehensive evaluations into their care can facilitate early detection and intervention for life-threatening conditions. Ultimately, men with azoospermia should receive ongoing monitoring to address their specific health concerns, thus improving their long-term health outcomes.

Börjeson-Forssman-Lehmann syndrome (BFLS) is a rare X-linked intellectual disability. The main features of the patients include intellectual disability/global developmental delay, characteristic face, anomalies of fingers and toes, hypogonadism, linear skin hyperpigmentation, and tooth abnormalities in female patients, and obesity in male patients. A case of BFLS caused by a novel mutation of PHF6 gene who was treated in the Department of Pediatrics, Xiangya Hospital, Central South University was reported. The 11 months old girl presented the following symptons: Global developmental delay, characteristic face, sparse hair, ocular hypertelorism, flat nasal bridge, hairy anterior to the tragus, thin upper lip, dental anomalies, ankyloglossia, simian line, tapering fingers, camptodactylia, and linear skin hyperpigmentation. The gene results of the second-generation sequencing technology showed that there was a novel heterozygous mutation site c.346C>T (p.Arg116*) of the PHF6 (NM032458.3), variation rating as pathogenic variation. During the follow-up, the patient developed astigmatism, strabismus, awake bruxism, and stereotyped behavior, and the linear skin hyperpigmentation became gradually more evident. The disease is lack of effective therapy so far.

Objective:
To evaluate the effects of Testosterone Undecanoate Pills (TUP) on insulin resistance (IR) in type-2 diabetes men with hypogonadism.
METHODS:
We randomly divided 82 type-2 diabetes patients with hypogonadism into a treatment (n = 42) and a control group (n = 40), both maintaining their glucose- and lipid-reducing therapies, while the former treated orally with TUP in addition. After 6 months of medication, we compared the body mass index (BMI), waist circumference (WC), blood glucose level, HbA1c, lipid profile, IR index obtained by homeostatic model assessment (HOMA-IR), insulin sensitivity index (ISI), sex hormone levels, and sexual function scores between the two groups of patients.
RESULTS:
Compared with the baseline, the patients in the treatment group showed significant decreases after medication in BMI ([26.71 ± 2.39] vs [25.15 ± 2.28] kg/m2, P <0.05), WC ([89.96 ± 9.13] vs [85.03 ± 9.58] cm, P <0.05), HbA1C ([7.73 ± 1.31] vs [7.01 ± 1.25] %, P <0.05), and triglyeride ([1.97 ± 0.83] vs [1.41 ± 0.69] mmol/L, P <0.05), a markedly elevated level of total testosterone ([7.16 ± 2.21] vs [14.22 ± 2.63] nmol/L, P <0.05), and remarkable improvement in HOMA-IR (3.76 ± 1.18 vs 2.55 ± 1.03, P <0.05), ISI (96 ± 51 vs 138 ± 53, P <0.05) and total scores of the Aging Males' Symptoms (P <0.05). But no significant changes were observed in the scores of the International Index of Erectile Function (IIEF) after treatment (13.28 ± 6.38 vs 14.95 ± 6.08, P >0.05).
CONCLUSIONS
TUP can significantly improve insulin resistance in type-2 diabetes men with hypogonadism.

As more and more studies suggest that type 2 diabetes mellitus (T2DM) is closely related to male hypogonadism, people begin to pay more attention to the role of testosterone in the development of T2DM and the effect and safety of testosterone supplementary therapy. There is some controversy in randomized controlled studies and meta-analyses about the effects of testosterone supplementation on the blood glucose level, androgen deficiency symptoms, and cardiovascular diseases. This review focuses on the diagnosis of hypogonadism in T2DM males, differences in the therapeutic effects and safety of testosterone replacement among different studies, and rational use of testosterone supplementation for T2DM patients.

ObjectiveTo analyze the clinical characteristics of secondary male hypogonadism induced by sellar space-occupying lesion, explore its pathogenesis, and improve its diagnosis and treatment.
METHODSWe retrospectively analyzed the clinical data about 22 cases of secondary male hypogonadism induced by sellar space-occupying lesion, reviewed related literature, and investigated the clinical manifestation, etiological factors, and treatment methods of the disease. Hypogonadism developed in 10 of the patients before surgery and radiotherapy (group A) and in the other 12 after it (group B). The patients received endocrine therapy with Andriol (n=7) or hCG (n=15).
RESULTSThe average diameter of the sellar space-occupying lesions was significantly longer in group A than in B ([2.35±0.71] vs [1.83±0.36] cm, P<0.05) and the incidence rate of prolactinomas was markedly higher in the former than in the latter group (60% vs 0, P<0.01). The levels of lutein hormone (LH), follicle stimulating hormone (FSH) and testosterone (T) were remarkably decreased in group B after surgery and radiotherapy (P<0.01). Compared with the parameters obtained before endocrine therapy, all the patients showed significant increases after intervention with Andriol or hCG in the T level ([0.78±0.40] vs [2.71±0.70] ng/ml with Andriol; [0.93±0.44] vs [3.07±0.67] ng/ml with hCG) and IIEF-5 score (5.00±2.61 vs 14.50±3.62 with Andriol; 5.36±1.82 vs 15.07±3.27 with hCG) (all P<0.01). The testis volume increased and pubic hair began to grow in those with hypoevolutism. The patients treated with hCG showed a significantly increased testis volume (P<0.01) and sperm was detected in 7 of them, whose baseline testis volume was markedly larger than those that failed to produce sperm ([11.5±2.3] vs [7.5±2.3] ml, P<0.01). Those treated with Andriol exhibited no significant difference in the testis volume before and after intervention and produced no sperm, either.
CONCLUSIONSHypothyroidism might be attributed to surgery- or radiotherapy-induced damage to the pituitary tissue, space-occupying effect of sellar lesion, and hyperprolactinemia. Both Andriol and hCG can improve the T level and erectile function, but the former does not help spermatogenesis.

OBJECTIVETo observe the clinical effect of low-dose testosterone undecanoate capsules combined with tadalafil on late-onset hypogonadism (LOH) accompanied with ED.
METHODSNinety cases of LOH accompanied with ED who met the inclusion criteria were randomly divided into a control group and a combination therapy group, the former treated with tadalafil and the latter with low-dose testosterone undecanoate capsules combined with tadalafil. The LOH symptoms, IIEF-5 scores, sexual encounter profile (SEP) scores, prostate volumes, and the levels of total testosterone (TT), free testosterone (FT) and prostatic specific antigen (PSA) were recorded and compared between the two groups before and after treatment.
RESULTSThe IIEF-5 and SEP scores and the TT and FT levels were 20.6 +/- 3.8, 4.02 +/- 1.08, (15.4 +/- 3.4) nmol/L and (0.391 +/- 0.062) nmol/L, respectively, in the combination therapy group after treatment, significantly higher both than 15.7 +/- 3.9, 1.49 +/- 0.82, (10.1 +/- 1.2) nmol/L and (0.200 +/- 0.045) nmol/L before treatment (P < 0.01) and than 8.6 +/- 3.6, 3.50 +/- 1.21, (10.2 +/- 1.2) nmol/L and (0.210 +/- 0.051) nmol/L in the control group after treatment (P < 0.01).
CONCLUSIONLow-dose testosterone undecanoate capsules combined with tadalafil has a definite clinical effect and no obvious adverse reactions in the treatment of LOH accompanied with ED.

PURPOSE: The aim of this study was to observe the clinical features of a bezoar-induced small bowel obstruction and to investigate the role of abdominal computed tomography (CT) in establishing the diagnosis. METHODS: We retrospectively reviewed 20 cases of bezoar-induced small bowel obstruction in our hospital from 1996 to 2010. RESULTS: Thirteen patients (65%) had a history of abdominal surgery. Nine patients (45%) were diagnosed with a bezoar before surgery, seven patients were diagnosed by using abdominal CT, and two patients were diagnosed with a small bowel series. Abdominal CT was performed in 15 patients, and the diagnostic accuracy was 47% (7/15). Surgery revealed ten bezoars in the jejunum and 11 in the ileum. Two patients had bezoars found concurrently in the stomach. Spontaneous removal took place in two patients. An enterotomy and bezoar extraction was performed in 15 patients. Fragmentation and milking, a small bowel resection, and a Meckel's diverticulectomy were performed in one patient each. Early operative treatment was possible (P = 0.036) once the bezoar had been diagnosed by using abdominal CT. There tended to be fewer postoperative complications in patients who were diagnosed with a bezoar by using abdominal CT, but the result was not statistically significant (P = 0.712). CONCLUSION: A preoperative diagnosis of bezoar-induced small bowel obstruction by using clinical features was difficult. Increased use of abdominal CT led to a more accurate diagnosis and to earlier surgery for bezoar-induced small bowel obstructions, thereby reducing the rate of complications.

INTRODUCTION: The iliac crest has been the accepted place to obtain bone for reconstruction in oral and maxillofacial surgery. The iliac crest has many advantages because of its accessibility, large amount of cancellous bone, relative ease of bone harvest, possibility of two team approach and ability to close the wound primarily. This study evaluated retrospectively the morbidity of bone harvesting from the anterior iliac crest to provide a logical guide for recognizing the complications and morbidities of an iliac crest bone graft. MATERIALS AND METHODS: Fifty healthy patients (mean age of 35.5 years; range 7 to 59) underwent iliac crest bone harvesting for a maxillofacial reconstruction from January 2007 to September 2009 at the Department of Oral and Maxillofacial Surgery in Kyungpook National University Hospital. Age, sex, size and kind of grafted bone, duration of pain on donor site, duration of gait disturbance, sensory deficit, scar, contour defect were measured in each patients by retrospective research. RESULTS: The mean duration of pain is 6.7 days, and mean duration of gait disturbance is 7.2 days. Most patients were free from gait disturbances and pain within 2 weeks and there was no correlation between the size of the harvesting block bone and the duration of gait disturbance or pain. However, this study showed that the duration of pain is associated with gait disturbance. In addition, most patients had no complaints regarding their surgical scar and contour defect, and only one patient had permanent impairment of the sensory function. Moreover, an iliac bone graft did not extend the length of hospitalization. CONCLUSION: This study suggests that split thickness bone harvesting from the inner table of the anterior iliac crest is a well accepted procedure with relatively low morbidity.
