Hypogonadotropic hypogonadism and anosmia（Kallmann's syndrome）associated with a marker chromosome
Hypogonadotropic hypogonadism anosmia（Kallmann's syndrome） marker chromosome
2009/2/23
A patient with hypogonadotropic hypogonadism and anosmia (Kallmann's syndrome) had an associated chromosomal abnormality. Evaluation of the hypothalamic pituitary axis showed undetectable basal LH a...
Three-generation evaluation of Y-chromosome microdeletion
Three-generation evaluation Y-chromosome microdeletion
2009/2/18
Sperm cells can be retrieved directly from the testis (testicular sperm extraction [TESE] procedure) and used for intracytoplasmic sperm injection (ICSI), circumventing underlying spermatogenetic ...
Use of a rat cDNA probe specific for the Y chromosome to detect male-derived cells
Sty gene polymerase chain reaction
2009/2/17
A cDNA probe that exhibits specificity for the rat Y chromosome was generated by using a set of primers specific to the murine Sry gene, the sex-determining region of the Y chromosome. A 459-base pa...
Assignment of the gene for human intra-acrosomal protein SP-10 to the p12----q13 region of chromosome 11
Spermatogenesis testis-specific gene somatic
2009/2/7
The human sperm antigen SP-10 is a testis-specific, intra-acrosomal protein associated with the membranes of the acrosomal vesicle. The molecule has been designated a "primary vaccine candidate" b...
Fluorescence in situ hybridization analysis of sex-chromosome mosaicism in azoospermic men
Azoospermia chromosome aberration infertility marker
2008/12/29
A retrospective study was carried out to determine the prevalence of sex-chromosome mosaicism among azoospermic men and to evaluate the feasibility of using fluorescence in situ hybridization (FISH)...
Separation of ram spermatozoa bearing X and Y chromosome by centrifugal countercurrent distribution in an aqueous two-phase system
ram spermatozoa X and Y chromosome centrifugal countercurrent aqueous two-phase system

Chromosomal Abnormalities and Y Chromosome Microdeletions in Infertile Men With Varicocele and Idiopathic Infertility of South Indian Origin
Genetic defects male infertility cytogenetic study STS markers
2008/12/22
Various factors cause spermatogenesis arrest in men and, in a large number of cases, the underlying reason still remains unknown. Little attention is paid to determining the genetic defects of varic...
Sex Chromosome Alignment at Meiosis of Azoospermic Men With Azoospermia Factor Microdeletion
Azoospermia chromosome pairing FISH Y chromosome microdeletion
2008/12/22
Deletions in the q arm of the Y chromosome result in spermatogenesis impairment. The aim of the present study was to observe the X and Y chromosome alignment in the spermatocytes of men with Y chr...
Evaluation of Chromosome Breakage and DNA Integrity in Sperm：An Investigation of Remote Semen Collection Conditions
Snap-freezing sperm-FISH TUNEL neutral comet assay

Collection of ejaculated semen at a remote site (outside of the laboratory) would facilitate participation rates and geographic diversity in reproductive epidemiology studies. Our study addressed ...
Y Chromosome Deletions in Azoospermic Men in India
Male infertility STS markers repeat sequence
2008/12/19
Genetic factors cause about 10% of male infertility. Azoospermia factors (AZFa, AZFb, AZFc) are considered to be the most important for spermatogenesis. We therefore made an attempt to evaluate the ...
