Non-linear association between androgen receptor CAG and GGN repeat lengths and reproductive parameters in fertile European and Inuit men.
Recently the dogma that there is an inverse linear association between androgen receptor (AR) CAG and GGN polymorphisms and receptor activity has been challenged. We analysed the pattern of association between 21 male reproductive phenotypes and AR CAG/GGN repeat lengths in 557 proven-fertile men. A linear association was only found between sperm DNA fragmentation index (DFI) and CAG length, an...
متن کاملAssessment of Correlation between Androgen Receptor CAG Repeat Length and Infertility in Infertile Men Living in Khuzestan, Iran
Background The androgen receptor (AR) gene contains a polymorphic trinucleotide repeat that encodes a polyglutamine tract in its N-terminal transactivation domain (NTAD). We aimed to find a correlation between the length of this polymorphic tract and azoospermia or oligozoospermia in infertile men living in Khuzestan, Iran. MaterialsAndMethods In this case-control study during two years till 20...
متن کاملAndrogen receptor gene CAG and GGN repeat polymorphisms in Chilean men with primary severe spermatogenic failure.
There is ample documentation supporting the fact that androgens are required for normal spermatogenesis. A minority of infertile men have abnormal testosterone blood levels or mild androgen receptor mutations. We investigated the androgen receptor CAG and GGN repeat lengths in Chilean men with spermatogenic impairment. We studied 117 secretory azoospermic/oligozoospermic men (93 idiopathic and ...
متن کاملAssociation between polymorphic CAG repeat lengths in the androgen receptor gene and susceptibility to prostate cancer
BACKGROUND Previous studies have been conducted to reveal the relationship between androgen receptor CAG polymorphism and risk of prostate cancer, yet the results were elusive and controversial. Thus, this meta-analysis was performed to clarify this association. METHODS To obtain the relevant available studies, online databases PubMed, Embase, and Web of science were searched until September ...
متن کاملAssociations between androgen receptor CAG & GGN repeat polymorphism & recurrent spontaneous abortions in Chinese women
BACKGROUND & OBJECTIVES Recurrent spontaneous abortion (RSA) is a reproductive problem that occurs in women in reproductive age with a frequency of 1-3 per cent. Previous studies have reported high levels of serum androgens to be associated with RSAs. At the molecular level, the effect of androgens is mediated through the activation of the androgen receptor (AR). The CAG and GGN repeat polymorp...
