Filter by: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.
For a pregnancy to occur, an euploid embryo at blastocyst developmental stage, a receptive endometrium and the synchrony of both is crucial. Many studies lately investigated the influence of the endometrial thickness and pattern on the artificial reproductive technology (ART) outcome, however, with conflicting results.
To determine if two types of endometrial activation (Pipelle curette or Shepard catheter) prior to embryo transfer result in similar live birth rates. Also to determine if patients experience similar pain from both types of endometrial activation.
Endometrial thickness has been used as an indicator of risk for endometrial hyperplasia and carcinoma in asymptomatic perimenopausal women. However, there is no cutoff value in perimenopausal women and the same thickness does not express the same endometrial volume in different endometrium because uterine lengths may be different and endometrial irregularities may exist. Many studies assessed endometrial volume measured by three-dimensional (3D) TVS as a predictor of malignancy in women with postmenopausal bleeding. To our knowledge there is no study assess endometrial volume measured by two dimension TVS in prediction of endometrial pathology, however it is cheap and available than 3D TVS.
The goal of this interventional study is to evaluate the increasing in endometrial thickening after the intrauterine infusion of 0,5-1 ml of autologous Platelet-Rich Plasma (PRP) and the implantation rate in women with thin endometrium undergoing Embryo-transfer, in order to propose a novel therapeutic approach for women with an endometrium < 7 mm unresponsive to standard treatments.
The objective of this study is to compare the efficacy of oral, sublingual, vaginal, and no misoprostol prior to operative hysteroscopy in premenopausal women.
