Dr. Zitzmann one of the true heavyweights in the field!

Thread 'Effect of Androgen Receptor Polymorphism on Hypogonadism Severity'

Oct 19, 2024

*Average number of CAG repeats found was 23 ± 3.1, which is within the normal range as described by current literature

* Half of the patients (n=8) had [EF] subscores <14, indicating erectile dysfunction. However, Wilcoxon testing reveals that this difference is not significantly less than the cutoff (p=0.4375), a result likely due to the small sample size. These findings are consistent with the literature, which suggests that a correlation between CAG repeat length and erectile function only exists in eugonadal men.

* These data suggest that CAG repeat...

Dr. Michael Zitzmann, a prominent researcher in andrology and reproductive endocrinology, has made substantial contributions to elucidating the functional and clinical implications of the CAG trinucleotide repeat polymorphism in exon 1 of the androgen receptor (AR) gene on the X chromosome. This polymorphism encodes a variable polyglutamine tract in the AR protein's N-terminal domain, which inversely modulates the receptor's transcriptional activity: shorter repeats enhance AR transactivation, while longer repeats attenuate it, leading to subtle variations in androgen sensitivity even within normal testosterone ranges.
