Abstract
PURPOSE To investigate the prevalence of Y chromosome polymorphisms in Chinese men and analyze their associations with male infertility and female adverse pregnancy outcomes. METHODS The clinical data of 32,055 Chinese men who underwent karyotype analysis from October 2014 to September 2019 were collected. Fisher's exact test, chi-square test, or Kruskal-Wallis test was used to analyze the effects of Y chromosome polymorphism on semen parameters, azoospermia factor (AZF) microdeletions, and female adverse pregnancy outcomes. RESULTS The incidence of Y chromosome polymorphic variants was 1.19% (381/32,055) in Chinese men. The incidence of non-obstructive azoospermia (NOA) was significantly higher in men with the Yqh- variant than that in men with normal karyotype and other Y chromosome polymorphic variants (p < 0.050). The incidence of AZF microdeletions was significantly different among the normal karyotype and different Y chromosome polymorphic variant groups (p < 0.001). The detection rate of AZF microdeletions was 28.92% (24/83) in the Yqh- group and 2.50% (3/120) in the Y ≤ 21 group. The AZFb + c region was the most common AZF microdeletion (78.57%, 22/28), followed by AZFc microdeletion (7.14%,2/28) in NOA patients with Yqh- variants. There was no significant difference in the distribution of female adverse pregnancy outcomes among the normal karyotype and different Y chromosome polymorphic variant groups (p = 0.528). CONCLUSIONS Patients with 46,XYqh- variant have a higher incidence of NOA and AZF microdeletions than patients with normal karyotype and other Y chromosome polymorphic variants. Y chromosome polymorphic variants do not affect female adverse pregnancy outcomes.

Abstract
The present study aimed to perform chromosome examination and pedigree analysis on three patients with semen abnormality who had undergone in vitro fertilization–embryo transfer (IVF‐ET). Peripheral blood cell culture and chromosome karyotyping were performed on 4,200 individuals who had undergone chromosome examination. Among them, 155 pregnant women who had successfully conceived were subjected to amniotic cell culture and chromosome karyotyping and those with abnormal chromosome karyotype were further subjected to C‐banding and whole‐genome sequencing. Mosaicism for a 46,X,inv(Y)(p11.2q11.2)pat/45,X karyotype was identified in the probands and immediate adult male relatives. The incidence of this mosaicism in the study population was only 0.07% (3/4,200), which is reported for the first time. For the proband of pedigree A, the results of whole‐genome sequencing and other tests were normal, and the chromosome karyotype of IVF fetuses was 46,X,inv(Y)(p11.2q11.2)pat. All the male members of three pedigrees have normal phenotypes, with no features of Turner's syndrome (45,X) or hermaphroditism (45,X/46,XY), suggesting that the inverted Y chromosome is extremely unstable and particularly susceptible to loss in somatic cells. So we speculate this karyotype may be a unique type of inverted Y chromosome in somatic cells.

Abstract
The Y chromosome in mammals is variable, even in closely related species. Middle East blind mole rats Nannospalax ehrenbergi demonstrate autosomal variability, which probably leads to speciation. Here, we compare the mitotic and meiotic chromosomes of mole rats. For the first time, we studied the behavior of their sex chromosomes in the meiotic prophase I using electron microscopy and immunocytochemical analysis. Unexpectedly, the sex chromosomes of the 52- and 60-chromosome forms of mole rats showed different synaptic and recombination patterns due to distinct locations of the centromeres on the Y chromosomes. The absence of recombination in the 60-chromosome form, the asymmetric synapsis, and the short-term disturbance in the synaptic co-orientation of the telomeric regions of the X and Y chromosomes were revealed as specific features of mole rat sex bivalents. We suggest several scenarios of Y chromosome alteration in connection with species differentiation in mole rats.

Abstract
Constitutional chromosomal abnormalities are an important cause of miscarriage, infertility, congenital anomalies and mental retardation in humans. Pericentric inversions of the human Y-chromosome [inv(Y)] are rather common and show an estimated incidence of 0.6–1:1,000 in males in the general population. Most of the reported cases with inv(Y) are familial. For carriers of pericentric inversions the risk of mental retardation or multiple abortions is not apparently increased and there is no relation with abnormal phenotypic features. Polymerase chain reaction (PCR) analysis to detect microdeletions along the Y-chromosome as well as cytogenetic and fluorescence in situ hybridization (FISH) analysis were done to delineate the characteristics of an inv(Y) in a Syrian family. Thus, we present a detailed molecular-cytogenetic characterization of a father and his two sons having an inv(Y)(p11. 2q11.221∼q11.222) with varying mental retardation features but otherwise normal phenotype.

Abstract
Chromosome aberrations are found in 2-7% of couples with fertility problems and pericentric inversions are structural chromosomal abnormalities, potentially associated with infertility or multiple miscarriages. In this study, we report the first case of pericentric inversion of chromosome 12 associated with non-obstructive azoospermia. A karyogram revealed pericentric inversion of chromosome 12 with breakpoints at 12p12 and 12q12. Testicular histopathology confirmed the Sertoli cell-only syndrome.

Abstract
Pericentric inversions of the human Y chromosome (inv(Y)) are the result of breakpoints in Yp and Yq. Whether these breakpoints occur recurrently on specific hotspots or appear at different locations along the repeat structure of the human Y chromosome is an open question. Employing FISH for a better definition and refinement of the inversion breakpoints in 9 cases of inv(Y) chromosomes, with seemingly unvarying metacentric appearance after banding analysis, unequivocally resulted in heterogeneity of the pericentric inversions of the human Y chromosome. While in all 9 inv(Y) cases the inversion breakpoints in the short arm fall in a gene-poor region of X-transposed sequences proximal to PAR1 and SRY in Yp11.2, there are clearly 3 different inversion breakpoints in the long arm. Inv(Y)-types I and II are familial cases showing inversion breakpoints that map in Yq11.23 or in Yq11.223, outside the ampliconic fertility gene cluster of DAZ and CDY in AZFc. Inv(Y)-type III shows an inversion breakpoint in Yq11.223 that splits the DAZ and CDY fertility gene-cluster in AZFc. This inversion type is representative of both familial cases and cases with spermatogenetic impairment. In a further familial case of inv(Y), with almost acrocentric morphology, the breakpoints are within the TSPY and RBMY repeat in Yp and within the heterochromatin in Yq. Therefore, the presence of specific inversion breakpoints leading to impaired fertility in certain inv(Y) cases remains an open question.

Abstract
OBJECTIVE To analyze the meiotic segregation and an interchromosomal effect in sperm of an inv(Y) (p11.1;q11.2),t(10;15) (q25.2;q12) carrier. DESIGN Case report. SETTING Research institute. PATIENT(S) Man with a karyotype 46,X,inv(Y),t(10;15), normal sperm parameters, and secondary infertility. INTERVENTION(S) Multicolor fluorescence in situ hybridization using probes for chromosomes 10, 15, 8, 18, 21, X, and Y. MAIN OUTCOME MEASURE(S) Frequencies of meiotic segregation products and aneuploidy of chromosomes 8, 18, 21, X, and Y. RESULT(S) The most frequent type of meiotic segregation was the alternate (40.82%), followed by the adjacent 1 (28.09%), adjacent 2 (16.33%), and 3:1 (9.91%) segregations. Neither deviation from the expected 1:1 ratio of the X- and Y-bearing spermatozoa nor any evidence of an interchromosomal effect on aneuploidy of chromosomes X, Y, 8, 18, and 21 and diploidy was observed in the carrier compared with control donors. The disomies of chromosomes 8 and 21 were equally frequent in X- and Y-bearing spermatozoa of the carrier. CONCLUSION(S) The fluorescence in situ hybridization analysis of meiotic segregation and aneuploidy helps to personalize the reproductive risk in carriers of balanced structural chromosomal aberrations. Complete information concerning the quality of spermatogenesis is necessary in all donors (both translocation carriers and controls) implicated in interchromosomal effect studies.

Abstract
A boy with Down syndrome due to a free trisomy 21 also had a metacentric Y chromosome with an arm euchromatic and the other heterochromatic inherited from his phenotypically normal father. This chromosome was mitotically stable and hybridized with the DYZ3 probe precisely at its primary constriction; in addition, a subtelomeric Xp/Yp probe gave the expected signal near the end of the euchromatic arm. So, the proband's karyotype was 47,X,inv(Y)(p11q11.2),+21. Given the high frequency of both chromosome anomalies, we regard its concurrence as a mere coincidence. This observation, along with previous reports, allows us to classify the apparent pericentric inversions of the Y chromosome into two types: "true" inversions characterized by an alphoid single centromere and mitotic stability, and "false" inversions in which a nonalphoid centromere has taken over the usual alphoid centromere; indeed, these chromosomes are dicentric and mitotically unstable. Finally, the inv(Y) polymorphism in man compares with that documented in other mammal species, in which the rearranged Y chromosome neither impairs the fertility nor has other phenotypical consequences.
