Karyotypic abnormalities and molecular analysis of Y chromosome microdeletion in Iranian Azeri Turkish population infertile men.

Karyotypic abnormalities and molecular analysis of Y chromosome microdeletion in Iranian Azeri Turkish population infertile men. Syst Biol Reprod Med. 2019 Nov 05;:1-7 Authors: Akbarzadeh Khiavi M, Jalili A, Safary A, Gharedaghchi Z, Mirinezhad SK, Mehdizadeh A, Rahmani SA Abstract Infertility is one of the major health-threatening problems in communities which may lead to psychological problems among couples. Y chromosome abnormalities and microdeletions have recently been considered as one of the male infertility factors. The aim of this study was to evaluate different chromosomal disorders and azoospermia factor b (AZFb), AZFc and AZFd microdeletions in idiopathic non-obstructive oligo or azoospermia infertile men. One hundred infertile (78 azoospermia and 22 oligospermia) and 100 fertile men were included in this study. Luteinizing hormone (LH) and follicle stimulating hormone (FSH) levels were evaluated by electrochemiluminescence. Karyotyping was performed according to standard methods and interpreted using the International System for Human Cytogenetic Nomenclature (ISHCN) recommendation. For Y chromosome microdeletion analysis, a multiplex polymerase chain reaction (PCR) was performed using STS primers. Higher FSH (24.32 ± 15.32 versus 8.02 ± 3.37, p

In conclusion, our study showed that the frequency of Y chromosome microdeletion in male patients in Japan was similar to that reported in patients from other countries, and SRR was higher in patients with AZFc deletion. PMID: 31603142 [PubMed - as supplied by publisher]

Conclusion: Men with AZF microdeletions can achieve the delivery of healthy children using ICSI. In this series, it produced good implantation rate and obstetric and perinatal outcomes.

Abstract The aim of this study was to establish the prevalence of chromosomal abnormalities and microdeletions on the Y chromosome in Tunisian infertile men with severe oligozoospermia or non-obstructive azoospermia. In cases of azoospermia, we aimed also to correlate histological results after negative testicular sperm extraction with the type of Y chromosome microdeletion. 84 infertile patients and 52 controls were screened for karyotypic abnormalities using G-banding and Yq chromosome microdeletions using multiplex PCR. 7 infertile males (8.3%) carried chromosomal abnormalities and 8 (9.5%) presented Y chromoso...

Rationale: Small supernumerary marker chromosomes (sSMCs) can be usually discovered in the patients with mental retardation, infertile couples, and prenatal fetus. We aim to characterize the sSMC and explore the correlation between with sSMC and male infertility. Patient concerns: A 26-year-old Chinese male was referred for infertility consultation in our center after 1 year of regular unprotected coitus and no pregnancy. Diagnosis: Cytogenetic G-banding analysis initially described a mosaic karyotype 47,X,Yqh-,+mar[28]/46,X,Yqh-[22] for the proband, while his father showed a normal karyotype. The chromosome microa...

Rationale: Y;autosome translocations are associated with male infertility and azoospermia. Some carriers with a Y:22 translocation can produce offspring and transmit the translocation through generations without phenotypic repercussion. Hence, the clinical features of carriers with certain Y chromosome abnormalities remain uncertain. Patient concerns: An apparently healthy 33-year-old man, 175 cm tall and weighing 60 kg had a 6-month history of primary infertility. Diagnoses: The patient was diagnosed with oligoasthenozoospermia. A series of examinations have been performed to evaluate possible genetic causes o...

In this study, we sought to determine the frequency and the character of different Y chromosome microdeletion types in infertile men in southwest of China. In total, 1274 patients with azoospermia and oligozoospermia were recruited in southwest of China and screening for Y chromosome microdeletions in AZF regions by multiplex polymerase chain reaction. The incidence of AZF microdeletions in southwest of China is 12.87%, which is higher than the national average. Further investigations unveiled that azoospermia factor c (AZFc) is the most frequent type of all the AZF microdeletions. Additionally, the number and also the q...

We report the case of a 46-year-old Chinese male patient who visited our clinic complaining of infertility. Semen analysis revealed azoospermia, and azoospermia factor c region partial deletion (b1/b3) was detected using Y chromosome microdeletion analysis. Testicular sperm extraction was performed after genetic counseling. The bilateral ductus deferens and a portion of the epididymis were absent, whereas the remaining epididymis was expanded. Motile intratesticular spermatozoa were successfully extracted from the seminiferous tubule. On histopathology, nearly complete spermatogenesis was confirmed in almost every seminife...

Summary Disorders of sex development (DSD) are congenital abnormalities as an atypical development process in either gonadal or chromosomal structure. It is the cause of the abnormality in phenotype and characteristics. Chromosomal analysis plays an important role in the DSD determination. 45,X/46,XY mosaicism is a rare karyotype, and its prevalence is about 1.5 in 10,000 newborns. It affects the growth, hormonal balance, gonad development and histology. All data such as height, male general appearance, testis size and volume, external genitalia, spermogram and hormonal levels, testis pathology, Y chromosome microdeletion ...

Summary The pathogenic mechanisms by which varicocele disrupt spermatogenesis are not clearly understood. Over 30% of male infertility cases resulting from spermatogenic problems are associated with genetic abnormalities, and Y chromosome microdeletions are the second most frequent genetic cause. Here, we aimed to evaluate the frequency of Y chromosome microdeletion in infertile men with varicocele. A cross‐sectional study comprising 51 infertile men with varicocele presenting spermatogenesis failures was performed. Y chromosome microdeletion research was made using polymerase chain reaction. Of the 51 men with infertili...
