Objective: To explore the distribution of Traditional Chinese Medicine (TCM) syndrome types and their relationship with semen parameters in infertility male patients with varicocele (VC). METHODS: Using Questionnaire on Clinical Symptoms of Varicocele-Caused Male Infertility, we made an investigation among 147 infertility male patients with VC, determined the types of their TCM syndromes, obtained their semen parameters, and analyzed the distribution of the TCM syndrome types and their correlation with semen parameters. RESULTS: Of the TCM syndrome types identified, kidney deficiency and stagnated heat constituted the largest proportion (34.7%), and the mixed type accounted for a significantly higher percentage than the simple type (P < 0.05). The patients with kidney deficiency and stagnated heat, compared with those with other syndrome types, had a dramatically lower sperm concentration (［21.62 ± 9.25］ vs ［28.88 ± 12.92］ ×10⁶/ml, P < 0.01), but a higher percentage of morphologically abnormal sperm (［98.33 ± 0.15］% vs ［96.27 ± 0.18］%, P < 0.05) and DNA fragmentation index (［19.72 ± 3.17］% vs ［10.96 ± 3.82］%, P < 0.01). No statistically significant differences were observed in the percentage of progressively motile sperm among different TCM syndrome types. CONCLUSIONS Kidney deficiency and stagnated heat is a main TCM syndrome type in infertility male patients with varicocele and correlated with sperm concentration, the percentage of morphologically abnormal sperm and DNA fragmentation index.

Leukocytospermia is an ill-defined and poorly understood condition affecting up to 30% of male factor infertility. Current guidelines on leukocytospermia vary significantly, although it has been linked to increased rates of infertility, uncertainty about its clinical significance, diagnosis, and treatment remains. The guidelines are conflicting with sparse data scattered across different specialties and continents. This study aims to compare and contrast available international guidelines and recommendations. In addition to these guidelines, we sought to consolidate the findings of trials over the last several decades. English language articles on human observational studies, retrospective, prospective, clinical trials and randomized control trials were searched for using the following terms: “leukocytospermia, pyospermia, and male infertility.” Articles about treatment and management of leukocytospermia that were published between January 2010 and April 2018 were included, as well as four articles referenced in best practice and guideline statements from urological and andrological associations. Disagreements on this topic are highlighted as some guidelines describe no correlation between leukocytospermia and infertility while others show that treatment leads to improvement of sperm quality by many measures including improved pregnancy rate. Various treatments have been suggested including antibiotics, anti-inflammatory medications, and frequent ejaculation. There is a need for definitive characterization of Leukocytospermia as an infectious or inflammatory marker and a re-evaluation of the leukocyte concentration threshold. Additional studies investigating rates of conception as a measure of outcome are needed, to provide greater level of evidence and generalizability of leukocytopsermia management.

Despite advances in the field of male reproductive health, idiopathic male infertility, in which a man has altered semen characteristics without an identifiable cause and there is no female factor infertility, remains a challenging condition to diagnose and manage. Increasing evidence suggests that oxidative stress (OS) plays an independent role in the etiology of male infertility, with 30% to 80% of infertile men having elevated seminal reactive oxygen species levels. OS can negatively affect fertility via a number of pathways, including interference with capacitation and possible damage to sperm membrane and DNA, which may impair the sperm's potential to fertilize an egg and develop into a healthy embryo. Adequate evaluation of male reproductive potential should therefore include an assessment of sperm OS. We propose the term Male Oxidative Stress Infertility, or MOSI, as a novel descriptor for infertile men with abnormal semen characteristics and OS, including many patients who were previously classified as having idiopathic male infertility. Oxidation-reduction potential (ORP) can be a useful clinical biomarker for the classification of MOSI, as it takes into account the levels of both oxidants and reductants (antioxidants). Current treatment protocols for OS, including the use of antioxidants, are not evidence-based and have the potential for complications and increased healthcare-related expenditures. Utilizing an easy, reproducible, and cost-effective test to measure ORP may provide a more targeted, reliable approach for administering antioxidant therapy while minimizing the risk of antioxidant overdose. With the increasing awareness and understanding of MOSI as a distinct male infertility diagnosis, future research endeavors can facilitate the development of evidence-based treatments that target its underlying cause.

ObjectiveTo identify the etiology of chromosome abnormality in an infertile man and analyze the correlation between the genotype and phenotype.

METHODSWe analyzed the karyotype of an infertile male using the routine G-banding technique and then the chromosome abnormality of the patient by Illumina Human CytoSNP-12 Beadchip array.

RESULTSNegative results were found in the examination of the sex-determining region Y (SRY) gene and the STR locus in the AZF zone of the patient. The karyotype of the patient was 46, XX. SNP array showed a 1.05 Mb 19p12 duplication and a 0.93 Mb Xq27.1 duplication.

CONCLUSIONSThe patient was confirmed as a case of 46,XX male syndrome. The increased copies of the FGF13 gene may be the major causes of abnormal sex determination and testis development.

ObjectiveAutosomal dominant polycystic kidney disease (ADPKD) is one of the most common genetic renal diseases, which may cause oligoasthenospermia and azoospermia and result in male infertility. This study aimed to analyze the outcomes of preimplantation genetic diagnosis (PGD) in male patients with ADPKD-induced infertility.

METHODSWe retrospectively analyzed the clinical data on 7 male patients with ADPKD-induced infertility undergoing PGD from April 2015 to February 2017, including 6 cases of oligoasthenospermia and 1 case of obstructive azoospermia, all with the PKD1 gene heterozygous mutations. Following intracytoplasmic sperm injection (ICSI), we performed blastomere biopsy after 5 or 6 days of embryo culture and subjected the blastomeres to Sureplex whole-genome amplification, followed by haplotype linkage analysis, Sanger sequencing, array-based comparative genomic hybridization to assess the chromosomal ploidy of the unaffected embryos, and identification of the unaffected euploid embryos for transfer.

RESULTSOne PGD cycle was completed for each of the 7 patients. Totally, 26 blastocysts were developed, of which 12 were unaffected and diploid. Clinical pregnancies were achieved in 6 cases following 7 cycles of frozen embryo transplantation, which included 5 live births and 1 spontaneous abortion.

CONCLUSIONSFor males with ADPKD-induced infertility, PGD may contribute to high rates of clinical pregnancy and live birth and prevent ADPKD in the offspring as well. This finding is also meaningful for the ADPKD patients with normal fertility.

Human seminal plasma is rich in potential biological markers for male infertility and male reproductive system diseases, which have an application value in the diagnosis and treatment of male infertility. The methods for the detection of semen biochemical markers have been developed from the manual, semi-automatic to the present automatic means. The automatic detection of semen biochemical markers is known for its advantages of simple reagent composition and small amount of reagents for each test, simple setting of parameters, whole automatic procedure with few errors, short detection time contributive to batch detection and reduction of manpower cost, simple calibration and quality control procedure to ensure accurate and reliable results, output of results in the order of the samples in favor of clinical diagnosis and treatment, and open reagents applicable to various automatic biochemistry analyzers. At present, the automatic method is applied in the detection of such semen biochemical markers as seminal plasma total and neutral alpha-glucosidase, acid phosphatase, fructose, γ-glutamyl transpeptidase, zinc, citric acid, uric acid, superoxide dismutase and carnitine, sperm acrosin and lactate dehydrogenase C4, and semen free elastase, which can be used to evaluate the secretory functions of the epididymis, seminal vesicle and prostate, sperm acrosome and energy metabolism function, seminal plasma antioxidative function, and infection or silent infection in the male genital tract.

Infertility is a common medical condition which affects nearly 15% of the world population. Non-obstructive azoospermia (NOA) is a most challenging problem inducing male infertility and does not respond to the existing medication. Surgery is the primary method for obtaining sperm from NOA patients, but the outcome of testicular sperm extraction is unpredictable preoperatively. Recently, with the development of detection techniques for male infertility, some new biomarkers have come into notice, which may be of some value in predicting the outcome of microdissection testicular sperm extraction (MTSE) and evaluating male infertility. This article presents an overview of the known biomarkers contributive to the prediction of the outcome of MTSE for NOA patients.

While varicocele is the most common cause of surgically correctable infertility in adult males, with repair resulting in improved semen parameters in 60% to 80% of men and a higher likelihood of conception in up to 60% of men, the rationale for varicocele repair in the pediatric population is less clear. Additionally, prepubertal varicoceles are much less common and their management is controversial. Adolescents with a varicocele are often in the midst of a progressive disease process. Despite the high prevalence of varicocele and its association with progressive disease processes, the indications for adolescent varicocele repair and the effects thereof on paternity have been persistently challenging to study. This review will briefly present some of the current issues regarding adolescent varicocele from a pediatric urological point of view, including the evaluation of adolescent varicocele, the optimal surgical indications, the optimal choice of surgical intervention to be performed, and outcomes.

Background: The 47,XYY syndrome could result in fertility problems. However, seldom studies reported comprehensive researches on the embryonic development and pregnancy outcomes of these patients. This study aimed to evaluate the clinical outcomes of nonmosaic 47,XYY patients performed with fluorescent in situ hybridization (FISH) and preimplantation genetic diagnosis (PGD) treatment. Methods: This was a retrospective study. Between January 2012 and May 2017, 51 infertile males with nonmosaic 47,XYY syndrome underwent FISH-PGD were included in the study. According to sex chromosomal FISH results, embryos were classified as normal signal, no nuclei fixed, no signal in fixed nuclei, suspensive signal, and abnormal signal groups, respectively. The incidence of each group, the fixation rate, and hybridization rate were calculated. Embryonic development and pregnancy outcomes were also analyzed. The measurement data were analyzed with Student's t-test. The comparison of categorical data was analyzed with the Chi-square test and Fisher's exact test when expected cell count was <5. Results: The 53 PGD cycles with 433 embryos were analyzed. The fixation rate was 89.6%, while the hybridization rate was 96.4%. There were 283 embryos with two sex chromosomal signals with clear diagnosis (65.4%). The numbers of no nuclei fixed, no signal in fixed nuclei, suspensive signal, and abnormal signal groups were 45 (10.4%), 14 (3.2%), 24 (5.5%), and 67 (15.5%), respectively. Embryos with abnormal signals were abandoned. The number of good-quality embryos was 210 (57.4%), including implanted embryos on day 4/day 5 and cryopreserved. The rates of good-quality embryos in the no nuclei fixed (22.2%), no signal in fixed nuclei (28.6%), and suspensive signal groups (33.3%) were comparable (P > 0.05), and were significantly lower than the normal signal group (66.4%, P < 0.001). The clinical pregnancy rates of fresh and frozen embryos transferred cycles were 70.6% and 85.7%, respectively. Conclusions Among embryos with a clear diagnosis of sex chromosome, about one-fifth showed abnormal signals. Embryos with two sex chromosomal signals are more likely to develop into good-quality ones. The application of the PGD by FISH may help to improve the clinical outcome s.

Objective: To investigate the prevalence of Ureaplasma urealyticum (UU) infection in infertile men, its influence on routine semen parameters and the distribution of antisperm antibody (AsAb) and its types in infertile patients with UU infection. METHODS: We detected the positive rate of UU infection, semen parameters, and the distribution of AsAb and its types in 662 infertile men and 25 normal fertile male controls followed by comparison of the obtained data between the two groups of subjects. RESULTS: The positive rate of UU infection was significantly higher in the infertile men than in the normal controls (52.87% ［350/662］ vs 16.00% ［4/25］, χ2 = 11.68, P <0.05). The semen volume, sperm count, sperm concentration and percentage of progressively motile sperm were remarkably lower in the UU-positive infertile males than in the control group (P <0.05). No statistically significant difference was observed between the UU-positive and UU-negative groups in the positive rates of total AsAb (43.4% vs 36.5%, χ2 = 3.25, P >0.05) and AsAb IgA, IgM and IgG in the seminal plasma, or in the percentages of serum AsAb IgM (16.9% vs 20.5%, χ2 = 1.22, P >0.05) and IgG (32.7% vs 28.9%, χ2 = 0.99, P >0.05) except in that of serum AsAb IgA (23.6% vs 17.0%, χ2 = 4.03, P <0.05). CONCLUSIONS The UU infection rate is high in infertile males, which decreases the semen volume, total sperm count, motile sperm concentration and percentage of progressively motile sperm and increases the positive rate of serum AsAb IgA.
