TLDR
A genetic redundancy of the multi-copy genes in AZFb and AZFc and a causative relationship between the occurrence of first microdeletions then macro deletions in the repetitive structure of Yq11 is suggested where large palindromes are probably promoting multiple gene conversions andAZF rearrangements.About:

Genetic risk factors in male infertility.
Csilla Krausz,Claudia Giachini +1 more
TL;DR: There is an increasing interest towards genetic susceptibility factors to male infertility and the most promising polymorphisms are in genes involved in the endocrine regulation of spermatogenesis and on the Y chromosome, the “gr/gr” deletions.

Journal ArticleDOI
Chromosome abnormalities in sperm of individuals with constitutional sex chromosomal abnormalities.
TL;DR: Men with Y chromosome microdeletions showed a reduction of normal Y-bearing sperm, and an increase in nullisomic and XY-disomic sperm, suggesting an instability of the deleted Y chromosome causing its loss in germ cells, and meiotic alterations leading to XY non-disjunction.

TL;DR: The ability to probe fundamental genetics of human germ cell formation by complementation is demonstrated and it is indicated that DDX3Y functions in the earliest stages ofhuman germ cell development.
Journal ArticleDOI
Spermatogenesis-specific association of SMCY and MSH5.
TL;DR: The results suggest that SMCY may have a male‐specific function as a histone H3K4 demethylase by recruiting a meiosis‐regulatory protein to condensed DNA.

TL;DR: The male-specific region of the Y chromosome, the MSY, differentiates the sexes and comprises 95% of the chromosome's length, and is a mosaic of heterochromatic sequences and three classes of euchromatics sequences: X-transposed, X-degenerate and ampliconic.

TL;DR: The presence of not one but three spermatogenesis loci in Yq11 is proposed and that each locus is active during a different phase of male germ cell development.

TL;DR: Binary polymorphisms associated with the non-recombining region of the human Y chromosome (NRY) preserve the paternal genetic legacy of the authors' species that has persisted to the present, permitting inference of human evolution, population affinity and demographic history.

Localization of factors controlling spermatogenesis in the nonfluorescent portion of the human Y chromosome long arm.
TL;DR: It is suggested that on the distal portion of the nonfluorescent segment of the long arm of the Y, factors are located controlling spermatogenesis.

The human Y chromosome: an evolutionary marker comes of age
TL;DR: The availability of the near-complete chromosome sequence, plus many new polymorphisms, a highly resolved phylogeny and insights into its mutation processes, now provide new avenues for investigating human evolution.
