Abstract
The long arm of the Y chromosome (Yq) contains many amplified and palindromic sequences that are prone to self-reorganization during spermatogenesis, and tiny submicroscopic segmental deletions in the proximal Yq are called Y chromosome microdeletions (YCM). A retrospective study was conducted on male infertility patients of Zhuang ethnicity who presented at Reproductive Medical Center of Nanning between January 2015 and May 2023. Seminal fluid was collected for standard examination. YCM were detected by using a combination of multiplex PCR and agarose gel electrophoresis. Preparation of peripheral blood chromosomes and karyotyping of chromosomes was performed. 147 cases (9.22%) of YCM were detected in 1596 male infertility patients of Zhuang ethnicity. Significant difference was found in the detection rate of YCM between the azoospermia group and the oligospermia group (P < 0.001). Of all types of YCM, the highest detection rate was AZFc (n = 83), followed by AZFb + c (n = 28). 264 cases (16.54%) of sex chromosomal aberrations were detected. The most prevalent karyotype was 47, XXY (n = 202). The detection rate of sex chromosomal aberrations in azoospermia group was higher than that in severe oligospermia group and oligospermia group, and the differences were significant (P < 0.001). 28 cases (1.57%) of autosomal aberrations and 105 cases (6.58%) of chromosomal polymorphism were identified. The current research has some limitations due to the lack of normal men as the control group but suggests that YCM and chromosomal aberrations represent key genetic factors influencing spermatogenesis in infertile males of Zhuang ethnicity in Guangxi.

Abstract
BACKGROUND Male infertility is the inability of a male to conceive a fertile female during at least a year of unprotected sexual activity. A variety of medical conditions and treatments cause male infertility. Y chromosome microdeletion is an important cause of infertility among males. Various epidemiological factors also play a role in the occurrence of infertility. Our study aims to determine the association between Y-chromosome microdeletion and age, sperm count, body mass index (BMI), alcohol, and tobacco consumption. METHODS This study was conducted in 70 male infertility cases. Data was collected from 2018 to 2023 at the Genetic Lab, Department of Anatomy, All India Institute of Medical Sciences, Raipur, Chhattisgarh, India. Demographic profiles, including age, sperm count, weight and height, and history of smoking and drinking, were collected from individuals. BMI was calculated, and chromosome analysis was done for Y chromosome microdeletion. Both multiplex and singleplex methods were used to determine the microdeletion using a thermocycler (Applied Biosystems, VeritiTM 96-well Fast Thermal Cycler, 0.2 ml USA) in AZF, and the association between age, sperm count, BMI, alcohol, and tobacco was determined. RESULTS The number of regions deleted among individuals varies from one to seven. Regions Sy746, Sy143, and Sy145 were found to be commonly deleted. We found a positive, but not statistically significant, correlation between age and microdeletion (point biserial correlation coefficient (r) = 0.2, p-value = 0.097). When comparing age with sperm count, the results showed a negative correlation, highlighting the influence of age on sperm count (r (68) = 0.284, p = 0.017). In comparing BMI and microdeletion, no significant relationship (χ² = 3.7, p = 0.296) indicated independence between them. According to our observations, microdeletion affects all smokers and 45% of non-smokers. We found a significant association between smoking and microdeletion (χ2 = 4.49, P = 0.034). There was no statistically significant relationship between microdeletion and drinking (χ²(3) = 5.65, p = 0.13). CONCLUSION We discovered a significant positive association between smoking and a positive, but not statistically significant, correlation between age, BMI, and drinking, as well as a microdeletion. There are probably a lot of unidentified variables that affect successful fertilization and implantation. These could include variables that affect fertility and the success of reproduction on an environmental, genetic, and epigenetic level. The study reveals that Y chromosome microdeletion and other epidemiological factors coexist concurrently in cases of infertility. Assessing these variables is crucial for infertile patients. A community-based, comprehensive survey is required to assess the overall consequences of various epidemiological factors on infertility.

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.

Appl Clin Genet 2023; 16:155-164. [PMID: 37663123 PMCID: PMC10473397 DOI: 10.2147/tacg.s420030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Accepted: 08/04/2023] [Indexed: 09/05/2023] Open
Abstract
Background The Y chromosome has a specific region, namely the Azoospermia Factor (AZF) because azoospermia is typically reported in the microdeletion of the AZF region. This study aims to assess the characteristics of AZF microdeletion after screening a massive number of low sperm concentration men; and the Microdissection testicular sperm extraction (mTESE) outcomes for retrieving sperm from azoospermic patients. Materials and Methods This retrospective multiple-center study enrolled a total of 1121 men with azoospermia, cryptozoospermia, and severe oligozoospermia from December 2016 to June 2022. An extension analysis used a total of 17 STSs to detect the position-occurring microdeletion in the AZF region (AZFa, b, c, and/or d loci). Microdissection testicular sperm extraction (mTESE) was performed to retrieve sperm in azoospermic men diagnosed AZFc microdeletion. Results One hundred and fifty-three men carried AZF microdeletion were detected in the 1121 participants (13.64%). The incidences of AZF microdeletion were confined to AZF a, c, and d regions, both individual and concurrence, with the most common in the AZFc region accounting for 49.67%; There was no significant difference in clinical and paraclinical characteristics between the deleted regions, except FSH level (highest in AZFa microdeletion, p = 0.043). The AZFc region was the most common type of AZF microdeletion (49.67%), including complete microdeletion (4 patients) and gr/gr partial microdeletion (39 patients) with 50.00% and 63.63% in the success rate of mTESE, separately. Conclusion The absence of AZFa and/or AZFb regions often express the most severe phenotype - azoospermia and the increasing FSH level. The AZFc region played the most common microdeletion. Microdissection testicular sperm extraction (mTESE) was the possible therapy for sperm retrieval from the testis of azoospermia men having AZFc microdeletion.

Abstract
Background Background: Male infertility contributes to roughly 15% of all infertility cases in couples. The most common cause of male infertility is azoospermia, which is caused by genetic mutations. The connection between various single nucleotide polymorphisms in the PRM genes and AZF region microdeletions with male infertility has not been reported. Methods In this case-control study, 100 infertile males (33 with azoospermia, 48 with oligozoospermia, and 19 with severe oligozoospermia) were chosen as the study subjects, and 100 fertile males were selected. Total DNA from peripheral blood was used to amplify two sequence-tagged site markers through multiplex PCR to detect AZFc partial deletions, and SNPs in PRM1 and PRM2 were determined through PCR-RFLP. Furthermore, quantitative real-time PCR was conducted to evaluate PRM1, PRM2, and DAZ1 (found in the AZFc region) expression levels in testis tissue. Results The frequency of the rs779337774 SNP in the PRM2 gene in the study population had no significant differences. However, a significant association was observed between the rs737008CA genotype (P= 0.013) and the C allele (P= 0.025) as a risk factor for male infant mortality. The deletion of sY254 and sY255 was discovered in azoospermia and severe oligozoospermia patients. Furthermore, all of these genes showed considerably low expression levels. However, only DAZ1 was identified with diagnostic biomarker potential (AUC=0.742). Conclusion When these genes expression levels are reduced, the likelihood of spermatozoa retrieval in azoospermic individuals is elevated. Furthermore, no significant association was observed between PRM2 polymorphism and azoospermia; however, the CA genotype of PRM1 polymorphism is significantly associated with azoospermia incidence.

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.
