Abstract
BACKGROUND Male infertility has become a global health problem, and genetic factors are one of the essential causes. Y chromosome microdeletion is the leading genetic factor cause of male infertility. The objective of this study is to investigate the correlation between male infertility and Y chromosome microdeletions in Hainan, the sole tropical island province of China. METHODS We analyzed the semen of 897 infertile men from Hainan in this study. Semen analysis was measured according to WHO criteria by professionals at the Department of Reproductive Medicine, the First Affiliated Hospital of Hainan Medical University, where samples were collected. Y chromosome AZF microdeletions were confirmed by detecting six STS markers using multiple polymerase chain reactions on peripheral blood DNA. The levels of reproductive hormones, including FSH, LH, PRL, T, and E2, were quantified using the enzyme-linked immunosorbent assay (ELISA). RESULTS The incidence of Y chromosome microdeletion in Hainan infertile men was 7.13%. The occurrence rate of Y chromosome microdeletion was 6.69% (34/508) in the oligozoospermia group and 7.71% (30/389) in the azoospermia group. The deletion of various types in the AZF subregion was observed in the group with azoospermia, whereas no AZFb deletion was detected in the oligozoospermia group. Among all patients with microdeletions, the deletion rate of the AZFc region was the higher at 68.75% (44 out of 64), followed by a deletion rate of 6.25% (4 out of 64) for the AZFa region and a deletion rate of 4.69% (3 out of 64) for the AZFb region. The deletion rate of the AZFa region was significantly higher in patients with azoospermia than in patients with oligozoospermia (0.51% vs. 0.39%, p < 0.001). In comparison, the deletion rate of the AZFc region was significantly higher in patients with oligozoospermia (3.08% vs. 6.30%, p < 0.001). Additionally, the AZFb + c subregion association deletion was observed in the highest proportion among all patients (0.89%, 8/897), followed by AZFa + b + c deletion (0.56%, 5/897), and exclusively occurred in patients with azoospermia. Hormone analysis revealed FSH (21.63 ± 2.01 U/L vs. 10.15 ± 0.96 U/L, p = 0.001), LH (8.96 ± 0.90 U/L vs. 4.58 ± 0.42 U/L, p < 0.001) and PRL (263.45 ± 21.84 mIU/L vs. 170.76 ± 17.10 mIU/L, p = 0.002) were significantly increased in azoospermia patients with microdeletions. Still, P and E2 levels were not significantly different between the two groups. CONCLUSIONS The incidence of AZF microdeletion can reach 7.13% in infertile men in Hainan province, and the deletion of the AZFc subregion is the highest. Although the Y chromosome microdeletion rate is distinct in different regions or populations, the regions mentioned above of the Y chromosome may serve an indispensable role in regulating spermatogenesis. The analysis of Y chromosome microdeletion plays a crucial role in the clinical assessment and diagnosis of male infertility.

Front Endocrinol (Lausanne) 2024; 15:1340188. [PMID: 38455658 PMCID: PMC10917934 DOI: 10.3389/fendo.2024.1340188] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/17/2023] [Accepted: 02/12/2024] [Indexed: 03/09/2024] Open
Abstract
Introduction Fabry's disease (FD) is a genetic X-linked systemic and progressive rare disease characterized by the accumulation of globotriaosylceramide (GB3) into the lysosomes of many tissues. FD is due to loss-of-function mutations of α-galactosidase, a key-enzyme for lysosomal catabolism of glycosphingolipids, which accumulate as glycolipid bodies (GB). In homozygous males the progressive deposition of GB3 into the cells leads to clinical symptoms in CNS, skin, kidney, etc. In testis GB accumulation causes infertility and alterations of spermatogenesis. However, the precise damaging mechanism is still unknown. Our hypothesis is that GB accumulation reduces blood vessel lumen and increases the distance of vessels from both stromal cells and seminiferous parenchyma; this, in turn, impairs oxygen and nutrients diffusion leading to subcellular degradation of seminiferous epithelium and sterility. Methods To test this hypothesis, we have studied a 42-year-old patient presenting a severe FD and infertility, with reduced number of spermatozoa, but preserved sexual activity. Testicular biopsies were analyzed by optical (OM) and transmission electron microscopy (TEM). Activation and cellular localization of HIF-1α and NFκB was analyzed by immunofluorescence (IF) and RT-PCR on homogeneous tissue fractions after laser capture microdissection (LCMD). Results OM and TEM showed that GB were abundant in vessel wall cells and in interstitial cells. By contrast, GB were absent in seminiferous epithelium, Sertoli's and Leydig's cells. However, seminiferous tubular epithelium and Sertoli's cells showed reduced diameter, thickening of basement membrane and tunica propria, and swollen or degenerated spermatogonia. IF showed an accumulation of HIF-1α in stromal cells but not in seminiferous tubules. On the contrary, NFκB fluorescence was evident in tubules, but very low in interstitial cells. Finally, RT-PCR analysis on LCMD fractions showed the expression of pro-inflammatory genes connected to the HIF-1α/NFκB inflammatory-like pathway. Conclusion Our study demonstrates that infertility in FD may be caused by reduced oxygen and nutrients due to GB accumulation in blood vessels cells. Reduced oxygen and nutrients alter HIF-1α/NFκB expression and localization while activating HIF-1α/NFκB driven-inflammation-like response damaging seminiferous tubular epithelium and Sertoli's cells.

Reprod Biol Endocrinol 2023; 21:116. [PMID: 38053137 DOI: 10.1186/s12958-023-01168-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Accepted: 11/28/2023] [Indexed: 12/07/2023] Open
Abstract
BACKGROUND The incidence of Y chromosome microdeletions varies among men with infertility across regions and ethnicities worldwide. However, comprehensive epidemiological studies on Y chromosome microdeletions in Chinese men with infertility are lacking. We aimed to investigate Y chromosome microdeletions prevalence among Chinese men with infertility and its correlation with intracytoplasmic sperm injection (ICSI) outcomes. METHODS This single-center retrospective study included 4,714 men with infertility who were evaluated at the Reproductive Center of the First Affiliated Hospital of Sun Yat-sen University between May 2017 and January 2021. Semen analysis and Y-chromosome microdeletion via multiplex polymerase chain reaction were conducted on the men. The study compared outcomes of 36 ICSI cycles from couples with male azoospermia factor (AZF)cd deletions with those of a control group, which included 72 ICSI cycles from couples without male Y chromosome microdeletions, during the same period. Both groups underwent ICSI treatment using ejaculated sperm. RESULTS Among 4,714 Chinese men with infertility, 3.31% had Y chromosome microdeletions. The combined deletion of sY254 and sY255 in the AZFc region and sY152 in the AZFd region was the prevalent pattern of Y chromosome microdeletion, with 3.05% detection rate. The detection rates of AZF deletions in patients with normal total sperm count, mild oligozoospermia, severe oligozoospermia, cryptozoospermia, and azoospermia were 0.17%, 1.13%, 5.53%, 71.43%, and 7.54%, respectively. Compared with the control group, the AZFcd deletion group exhibited no significant difference in the laboratory results or pregnancy outcomes of ICSI cycles using ejaculated sperm. CONCLUSIONS This is the largest epidemiological study on Y chromosome microdeletions in Chinese men with infertility. The study results underline the necessity for detecting Y chromosome microdeletion in men with infertility and severe sperm count abnormalities, especially those with cryptozoospermia. The combined deletion of sY254 and sY255 in the AZFc region and sY152 in the AZFd region was the most prevalent Y chromosome microdeletion pattern. Among patients with AZFcd deletion and ejaculated sperm, ICSI treatment can result in pregnancy outcomes, similar to those without AZFcd deletion.

[PMID: 38164427 PMCID: PMC10757685 DOI: 10.18502/jri.v24i4.14157] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Accepted: 06/06/2023] [Indexed: 01/03/2024] Open
Abstract
Background Males with 45,X/46,XY karyotype have two different types of cells. This condition is associated with a wide range of clinical phenotypes. In infertile males, the mosaic 45,X/46,XY karyotype is a frequent sex chromosome defect and they might be able to conceive with the help of assisted reproductive technology; nevertheless, there is a potential risk of transmission of azoospermia factor (AZF) microdeletions in addition to 45,X to all the male progeny. In this case report, the purpose was to present a rare sex chromosomal mosaicism of an infertile man. Case Presentation Comprehensive molecular and cytogenetic analysis of an infertile male was performed in this case study. A 27-year-old male was presented with history of azoospermia and was unable to conceive after being involved in five years of marriage. Cytogenetic investigation revealed a rare mosaic karyotype pattern of 45,X/46,X,del(Y)(q12→qter). Y chromosome microdeletion (YMD) analysis revealed notable deletions of 06 loci. Comparative genomic hybridization (CGH) microarray was performed to investigate probable functional genetic associations. Conclusion Deletion of Y-linked genes leads to different testicular pathological conditions contributing to male infertility. Individuals with normal male phenotype harbor YMD, although size and location of the deletion do not always correspond well with quality of sperm. Therefore, in addition to semen analysis, identification of genetic variables is important which will play a crucial role in proper diagnosis and management of infertile couples. The present case study demonstrates the significance of comprehensive molecular testing and cytogenetic screening for individuals with idiopathic infertility.

Abstract
The present study aimed to investigate the occurrence of chromosomal karyotype abnormalities and azoospermia factor (AZF) microdeletion on the long arm of the Y chromosome (Yq) in infertile men, and to determine their association with infertility to ultimately improve clinical outcomes in these patients. A total of 1,980 azoospermic and oligospermic men from the outpatient department of the Fujian Maternity and Child Health Hospital (Fuzhou, China) were recruited between January 2016 and December 2019. Peripheral blood was used for karyotype analysis; AZF microdeletion analysis of the Yq was performed using capillary electrophoresis. Among the 1,980 patients, 178 had chromosomal abnormalities (9.0%; 178/1,980), of whom 98 had an abnormal number of chromosomes. Among the abnormal karyotypes, the most common was 47, XXY (80/178; 44.9%). AZF microdeletion on the Yq occurred at a rate of 10.66% (211/1,980); the most common type was the AZFb/c deletion (sY1192; 140/211; 66.4%). The present findings showed that karyotype abnormalities and AZF gene microdeletion are important drivers of male infertility. Specifically, men with Yqh- and del(Y)(q11) had a higher risk of AZF microdeletion. These results suggested that patient treatment could be personalized based on routine molecular genetic analysis, which could further alleviate the economic and emotional burden of undergoing redundant or ineffective treatments.

Abstract
The screening of genomic variations within the male-specific region of the mammalian Y chromosome (MSY) is one of the most effective ways to investigate paternal evolutionary history and identify molecular markers related to male fertility. The current study was to identify single nucleotide polymorphisms (SNPs) within single-copy genes of the ovine MSY, and confirm whether they are associated with testicular size. A total of 21 Y-specific gene fragments were successfully amplified to screen Y-SNPs in 956 rams across nine sheep breeds. Three Y-SNPs, including SRY16: g.88 A > G in South African Mutton Merino sheep, ZFY16: g.146 C > T in Suffolk and South African Mutton Merino sheep, and EIF2S3Y2: g.77 C > G in Hu and Tan sheep, were identified using DNA-pooled sequencing and PCR restriction fragment length polymorphism (PCR-RFLP) methods. The investigation of the global distribution for three Y-SNPs showed that the C allele of ZFY16: g.146 C > T co-segregated with haplogroup y-HC, and the C/G allele of EIF2S3Y2: g.77 C > G co-segregated with haplogroup y-HA/y-HB1 in Hu sheep according to data mining from a previous study. In addition, association analysis revealed that ZFY16: g.146 C > T had a significant effect on yearling scrotal circumference in Suffolk sheep, and EIF2S3Y2: g.77 C > G was significantly associated with testicular and epididymis weight in Hu sheep (P ≤ 0.05). The current study concluded that Y-SNPs were associated with testicular size in specific sheep, which provides valuable candidate makers for selecting elite rams at an early age.

Nongthombam PD, Malini SS. Association of DAZL polymorphisms and DAZ deletion with male infertility: a systematic review and meta-analysis. Genes Genomics 2022; 45:709-722. [PMID: 36434389 DOI: 10.1007/s13258-022-01345-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Accepted: 11/09/2022] [Indexed: 11/27/2022]
Abstract
BACKGROUND Various populations have been investigated for the occurrence of two key DAZL polymorphisms, 260A > G (rs11710967) and 386A > G (rs121918346), as well as complete DAZ cluster deletion, with conflicting results. OBJECTIVE The purpose of the current meta-analysis was to investigate if there is an association between DAZL polymorphisms and complete deletion of the DAZ cluster gene with male infertility. METHODS Up until September 2022, a thorough search was conducted in the Pubmed and Google scholar databases. For 260A > G polymorphism, 8 studies with 2077 cases and 1398 controls, 13 studies for 386A > G polymorphism (4343 cases and 3727 controls) and 17 studies of DAZ deletion (2820 cases and 1589 controls) were included in the pooled analysis. All of the studies were statistically analysed by Review Manager 5.4, and publication bias was evaluated with JASP 0.16.2.0 software utilising funnel plots and Egger's linear regression test. RESULTS The meta analysis result for pooled data indicated no association between 260A > G and 386A > G polymorphisms and male infertility in any of the genetic models or ethnicities. However, there was a definite correlation between complete deletion of the DAZ gene cluster and male infertility, with an OR = 13.23, 95% confidence interval (6.63-26.39), and p < 0.00001. In the stratified analysis by ethnicity, Caucasians and Asian ethnic groups showed the similar relationship. CONCLUSION In order to arrive at more definitive conclusions, further study should be conducted, including studies from a larger range of nations and nationalities.

Omics and Male Infertility: Highlighting the Application of Transcriptomic Data. Life (Basel) 2022; 12:life12020280. [PMID: 35207567 PMCID: PMC8875138 DOI: 10.3390/life12020280] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2021] [Revised: 02/03/2022] [Accepted: 02/07/2022] [Indexed: 12/15/2022] Open
Abstract
Male infertility is a multifaceted disorder affecting approximately 50% of male partners in infertile couples. Over the years, male infertility has been diagnosed mainly through semen analysis, hormone evaluations, medical records and physical examinations, which of course are fundamental, but yet inefficient, because 30% of male infertility cases remain idiopathic. This dilemmatic status of the unknown needs to be addressed with more sophisticated and result-driven technologies and/or techniques. Genetic alterations have been linked with male infertility, thereby unveiling the practicality of investigating this disorder from the “omics” perspective. Omics aims at analyzing the structure and functions of a whole constituent of a given biological function at different levels, including the molecular gene level (genomics), transcript level (transcriptomics), protein level (proteomics) and metabolites level (metabolomics). In the current study, an overview of the four branches of omics and their roles in male infertility are briefly discussed; the potential usefulness of assessing transcriptomic data to understand this pathology is also elucidated. After assessing the publicly obtainable transcriptomic data for datasets on male infertility, a total of 1385 datasets were retrieved, of which 10 datasets met the inclusion criteria and were used for further analysis. These datasets were classified into groups according to the disease or cause of male infertility. The groups include non-obstructive azoospermia (NOA), obstructive azoospermia (OA), non-obstructive and obstructive azoospermia (NOA and OA), spermatogenic dysfunction, sperm dysfunction, and Y chromosome microdeletion. Findings revealed that 8 genes (LDHC, PDHA2, TNP1, TNP2, ODF1, ODF2, SPINK2, PCDHB3) were commonly differentially expressed between all disease groups. Likewise, 56 genes were common between NOA versus NOA and OA (ADAD1, BANF2, BCL2L14, C12orf50, C20orf173, C22orf23, C6orf99, C9orf131, C9orf24, CABS1, CAPZA3, CCDC187, CCDC54, CDKN3, CEP170, CFAP206, CRISP2, CT83, CXorf65, FAM209A, FAM71F1, FAM81B, GALNTL5, GTSF1, H1FNT, HEMGN, HMGB4, KIF2B, LDHC, LOC441601, LYZL2, ODF1, ODF2, PCDHB3, PDHA2, PGK2, PIH1D2, PLCZ1, PROCA1, RIMBP3, ROPN1L, SHCBP1L, SMCP, SPATA16, SPATA19, SPINK2, TEX33, TKTL2, TMCO2, TMCO5A, TNP1, TNP2, TSPAN16, TSSK1B, TTLL2, UBQLN3). These genes, particularly the above-mentioned 8 genes, are involved in diverse biological processes such as germ cell development, spermatid development, spermatid differentiation, regulation of proteolysis, spermatogenesis and metabolic processes. Owing to the stage-specific expression of these genes, any mal-expression can ultimately lead to male infertility. Therefore, currently available data on all branches of omics relating to male fertility can be used to identify biomarkers for diagnosing male infertility, which can potentially help in unravelling some idiopathic cases.

S Al-Ouqaili MT, Al-Ani SK, Alaany R, Al-Qaisi MN. Detection of partial and/or complete Y chromosome microdeletions of azoospermia factor a (AZFa) sub-region in infertile Iraqi patients with azoospermia and severe oligozoospermia. J Clin Lab Anal 2022; 36:e24272. [PMID: 35122324 PMCID: PMC8906023 DOI: 10.1002/jcla.24272] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2021] [Revised: 01/23/2022] [Accepted: 01/24/2022] [Indexed: 12/08/2022] Open
Abstract
BACKGROUND This study aimed to analyze the incidence of azoospermia factor a (AZFa) microdeletions in the Y chromosome and their association with male infertility in a population with azoospermia and severe oligozoospermia from Iraq. METHODS A total of 75 infertile Iraqi males and 25 healthy controls were included in this study. The semen analysis was performed to determine the azoospermia, severe oligozoospermia, or normal cases. The AZFa microdeletions were investigated using the real-time polymerase chain reaction (real-time PCR). Then, AZFa sub-region deletions were investigated by a conventional PCR. RESULTS In total, 40 men with azoospermia and 35 men with severe oligozoospermia were selected. Out of 75 infertile males, 46 (61.3%) individuals had AZFa microdeletions, of whom 32 (69.6%) had partial deletion, while 14 (30.4%) males had complete deletion using real-time PCR. The frequency of microdeletions was significantly different between the infertile and control group (p-value < 0.00001). The proportion of AZFa microdeletions appeared higher in azoospermia men (72.5%, n = 29/40) than severe oligozoospermia men (48.6%, n = 17/35), but based on the conventional PCR results, only one azoospermia patient (2.2%) was shown to have complete AZFa deletion, while the other 45 patients (97.8%) had partial AZFa deletions. CONCLUSION In this study, the partial AZFa microdeletions were more numerous than complete AZFa deletion. According to our results, the AZFa microdeletions might be associated with male infertility and spermatogenic failure. It is recommended to investigate the AZFa sub-region microdeletions in patients that shown AZFa microdeletions in primary screening.
