OBJECTIVE To report a new complication after laparoscopic surgery i.e recurrence of endometrium and leiomyoma fragments from uterine tissue residues after laparoscopic hysterectomy or laparoscopic myomectomy. Methods : This study was carried out on three patients with the recurrence of endometrium or leiomyoma fragments from tissue residues after laparoscopic hysterectomy or laparoscopic myomec...

OBJECTIVE This study is to investigate effects of bisphenol A (BPA) on the blastocyst implantation in endometrium. METHODS Pregnant mice were orally administered with BPA. Implantation sites were examined, and serum estrogen level was assayed with ELISA. Protein expression levels were detected with immunohistochemistry and immunofluorescence staining. RESULTS High doses (400 and 600 mg/kg/d...

Lysis of the blastocyst coverings in the rabbit normally starts at the abembryonic hemisphere of the blastocyst facing the antimesometrial endometrium. Theoretically, this restricted effect could be caused by factors locally produced by abembryonic trophoblast, antimesometrial endometrium, or a combination of them. Blastocysts abnormally implanting with reversed orientation exhibit lysis of bla...

Ultrasonography of the endometrium is a noninvasive way to evaluate the chance of successful implantation during in vitro fertilization treatment. Ultrasound parameters of endometrial receptivity include endometrial thickness, endometrial pattern, endometrial volume, Doppler studies of uterine vessels and the endometrium. Endometrial thickness, pattern and volume are not predictive of pregnancy...

The structural changes of ,the uterine endometrium during the menstrual cycle are clear and easily recognised but con· siderable disorder of function may be associated with little or no deviation from the normal histological pattern. For instance, in cases o£ sterility, habitual abortion, dysmenorrhea and functional uterine bleeding the endome,trium commonly shows no structural abnormality and ...

Embryo implantation requires both an activated blastocyst and a receptive endometrium. The human endometrium undergoes extensive remodeling in each menstrual cycle to prepare the endometrium for implantation, should conception occur in that cycle. For most of the cycle, the endometrium is retained in a non-receptive or refractory state and it will support implantation of the blastocyst for only...

Recently, much evidence has indicated that sex hormone-binding globulin (SHBG) and corticosteroid-binding globulin (CBG) play a role in the intracellular action of sex steroids in target cells. In the present work, expression of SHBG mRNA and CBG mRNA was demonstrated in tissues of human normal endometrium and pelvic endometriosis, using the reverse transcription-polymerase chain reaction (RT-P...

Bone marrow derived cells engraft to the uterine endometrium and contribute to endometriosis. The mechanism by which these cells are mobilized and directed to the endometrium has not been previously characterized. We demonstrate that human endometrial stromal cells (hESCs) produce the chemokine CXCL12 and that bone marrow cells (BMCs) express the CXCL12 receptor, CXCR4. Treatment with physiolog...
