Endometrial receptivity plays a crucial role in the establishment of a healthy pregnancy in cycles of assisted reproduction. The endometrium as a key factor during reproduction can be assessed in multiple ways, most commonly through transvaginal grey-scale or 3-D ultrasound. It has been shown that controlled ovarian hyperstimulation has a great impact on the uterine lining, which leads to diffe...
There are many markers to indicate the preparation of endometrium for successful implantation, and these manifest during the implantation window. Today TVS color Doppler can reliably show the increase in blood flows during the periand postovulatory phase and objectively assess these flows to predict endometrial receptivity.
In cycling human endometrium, menstruation is followed by rapid estrogen-dependent growth. Upon ovulation, progesterone and rising cellular cAMP levels activate the transcription factor Forkhead box O1 (FOXO1) in endometrial stromal cells (EnSCs), leading to cell cycle exit and differentiation into decidual cells that control embryo implantation. Here we show that FOXO1 also causes acute senesc...
OBJECTIVE To investigate the level of expression of prostaglandin receptivity and uptake factors in eutopic and ectopic endometrium of women with endometriosis. DESIGN Prospective study. SETTING Human reproduction research laboratory. PATIENTS Seventy-eight patients with endometriosis and thirty healthy control subjects. INTERVENTION(S) Endometrial and endometriotic tissue samples were ...
Increasing evidence has shown that miRNAs play important roles in endometrium development during the menstrual cycle in humans and many other animals. Our previous data indicated that miR-182 levels increase 15.55-fold and pleiotrophin (PTN) levels decrease 20.97-fold in the receptive endometrium (RE, D15) compared with the pre-receptive endometrium (PE, D5) in dairy goats. The present study sh...
Zhuyun recipe (ZYR) is a traditional Chinese medicine that has been widely used as an infertility treatment for a number of years. Although the therapeutic effects are desirable and satisfactory, the therapeutic mechanism of ZYR remains poorly understood. In the present study, pinopodes were investigated as an important morphological marker of endometrial receptivity, in order to further invest...
STUDY QUESTION Does prolonged exposure of the endometrium to hCG, as experienced after ovulation induction in an assisted reproduction technology (ART) cycle, affect functional measures of endometrial receptivity? SUMMARY ANSWER Prolonged endometrial hCG exposure detrimentally affects the manner in which the endometrium can respond to hCG secreted by the blastocyst. WHAT IS KNOWN ALREADY Pr...
