Calcium ions play an important role in the establishment and maintenance of pregnancy, but molecular and cellular regulatory mechanisms of calcium ion action in the uterine endometrium are not fully understood in pigs. Previously, we have shown that calcium regulatory molecules, transient receptor potential vanilloid type 5 (TRPV6) and calbindin-D9k (S100G), are expressed in the uterine endomet...

The stainless steel ring intrauterine device (IUD) (Figure 1A) is widely used in China. Very often this type of IUD can be removed in the outpatient clinic by using an IUD removal hook. A 32-year-old Chinese woman was referred for removal of an IUD that had been inserted 7 years previously in China. With the use of an IUD removal hook, only part of the device, which appeared to be a stainless s...

Secretory leukocyte protease inhibitor (SLPI) is a neutrophil elastase inhibitor which also has antibacterial and anti-inflammatory properties. It is found associated with mucosal membranes. Although SLPI has been reported in the cervix it has not thus far been reported in human endometrium. This study investigates the presence of SLPI in endometrium, first trimester decidua and trophoblast. Cu...

endometrial calcification along with ossification is an uncommon clinical entity. most of the cases are asymptomatic or present with secondary infertility. endometrial ossification associated with repeated abortions has been reported very infrequently. here we report a case of endometrial calcification with ossification  due to retained fetal bony tissue in a 38 year old symptomatic female havi...

background: endometrial integrin expression changes might be a reason for implantation failure in polycystic ovarian syndromes (pcos). objective: assessment of integrin genes and proteins expression upon endometrium in the pcos experimental mouse model was the main goal of this study. materials and methods: 30 nmri female mice were equally divided into control, experimental (pcos; received estr...

background: the pregnancy rate during in-vitro fertilization (ivf) following progesterone supplement still remains very low at around 20%. objective: to investigate the effects of peanut oil itself on the endometrial receptivity, the pregnancy success rate and fertility during the peri-implantation time in hyper stimulated and normal rats. materials and methods: thirty-six adult sprague dawley ...

Many species exhibiting hemochorial placentation experience an accumulation of macrophages in the endometrium during pregnancy. For the present study, it was tested whether macrophages also accumulate in the endometrium of the sheep, which is a species undergoing an epitheliochorial placentation. An additional objective was to determine whether regulation of endometrial macrophage number occurs...
