Endometrial tissue is a hormonal-dependent tissue in both pre- and postmenopausal period. The endometrial cells are expressing receptors for all sex hormones, mainly for estrogen, progesterone and androgens. The proper response of the endometrial cells on hormones is crucial for a well-balanced fluctuation of endometrial tissue. If, for any reason, these responses are altered, this may lead to benign or malignant lesions. The androgens, through their receptors, decrease the proliferation of the endometrial cells. After menopause, the number of androgens receptors (ARs) increases in proportion to estrogen receptors and this may lead to endometrial atrophy. If the functionality of ARs is decreased, the effect of estrogen increases and this may possibly lead to endometrial hyperplasia or to endometrial cancer. The AR gene is located on the X chromosome and consists of 8 exons. Genetic research has shown that on exon 1, there is an area of trinucleotide Cytosine- Adenosine- Guanin (CAG) repeats which controls the functionality of the receptor. The more CAG repeats, the less responsive the receptor. The goal of this research is to study the AR gene polymorphism and particularly the number of CAG repeats on exon 1, in patients with known endometrial pathology (benign and malignant). The results will be compared with a random sample of the general population without endometrial pathology.
