Hst7：a male sterility mutation perturbing sperm motility, flagellar assembly, and mitochondrial sheath differentiation
Allele asthenospermia axoneme t complex t haplotype
2009/2/17
Hst7, a mouse hybrid sterility locus, has been mapped in close linkage to four other hybrid sterility loci, on proximal chromosome 17 within the t complex. When an allele (s) of Hst7 from the specie...
CAG repeat length analysis and mutation screening of the androgen receptor gene in Japanese men with idiopathic azoospermia
Male infertility Kennedy disease sperm production
2008/12/29
Because androgens are required for normal spermatogenesis, we are investigating abnormalities in the androgen receptor as a possible cause of impaired spermatogenesis in patients with idiopathic mal...
A Novel Androgen Receptor Mutation Resulting in Complete Androgen Insensitivity Syndrome and Bilateral Leydig Cell Hyperplasia
Androgens androgen receptor gene
2008/12/24
Androgens drive male secondary sexual differentiation and maturation. Mutations in the androgen receptor (AR) gene cause a broad spectrum of abnormal phenotypes in humans, ranging from mild throu...
Single-Nucleotide Polymorphisms and Mutation Analyses of the TNP1 and TNP2 Genes of Fertile and Infertile Human Male Populations
Protamine transition nuclear protein sperm male infertility genome promoter SNPs
2008/12/23
Previously, we examined the relationship between protamine gene variations and human male infertility. In this study, we show specific variability in the transition nuclear protein genes (TNPs) of...
