Decidual natural killer cells accumulate at the fetal-maternal interface and play a key role in a successful pregnancy. However, their origin is still unknown. Do they derive from peripheral natural killer cells recruited in decidua or do they represent a distinct population that originates in situ? Here, we identified natural killer precursors in decidua and uterus of pregnant mice. These prec...

Intra uterine fetal death is a most traumatic event for the pregnant woman and her family. When they present to the obstetrician, the family’s immediate concern is to get the pregnancy terminated. When we are dealing with IUFD in a scarred uterus, the option of repeat cesarean takes the second place in front of vaginal trial, which carries the risk of rupture uterus with it. Thus this dilemmati...

INTRODUCTION Torsion of the uterus is defined as a rotation of more than 45° around the long axis of the uterus; 2/3 of cases are dextrorotations. The extent of rotation usually ranges from 45° to 180°. OBJECTIVE The purpose of the article was to present a case study of a postmenopausal woman with uterine torsion and myomas and to review the articles discussing the problem of rotated non-preg...

This study was carried out to compare the histomorphological structures of oviductal regions of the apparently healthy adult laying hens (Gallus gallus dometicus) and ducks (Ansa ansa domesticus). For this purpose, 20 hens and 20 female ducks aged between 1-1.5 years were used. After euthanasia, the oviducts were dissected out and all of the gross morphometrical parameters including length, wid...

Mesotocin, an oxytocin-like peptide, stimulates uterine contractions during marsupial parturition. Female marsupials have two separate uteri, and in monovular species, the uterus with the conceptus is gravid, whereas the contralateral uterus is nongravid. Marsupials are unique because systemic and feto-placental factors in the regulation of uterine function can be differentiated. In pregnant ta...

BACKGROUND Uterus transplantation may be the only theoretical option for some women, for example, those with congenital uterine infertility or who have undergone hysterectomy. In this study, we evaluated the intra- and post-operative blood flow conditions of vascular anastomosed regions and the blood-perfused area of the transplanted uterus in a cynomolgus macaque model of uterus autotransplant...

Small proline-rich protein 2a (Sprr2a) is one of the structural components of the cornified keratinocyte cell envelope that contributes to form a protective barrier in the skin against dehydration and environmental stress. Interestingly, Sprr2a mRNA is detected in the mouse uterus and is regulated by 17β-oestradiol (E2). In the present study, we investigated the effects of E2 and oestrogenic co...

The oviduct is an important organ in reproduction where fertilization occurs, and through which the fertilized eggs are carried to the uterus in mammals. This organ is highly polarized, where the epithelium forms longitudinal folds along the ovary-uterus axis, and the epithelial multicilia beat towards the uterus to transport the ovulated ova. Here, we analyzed the postnatal development of mous...

In this study we examined the gross anatomy of the uterus and vagina in turkeys in egg production. With no uterine egg mass, removal of the tunica serosa that enclosed the uterus revealed deep periodic in-folding of the muscularis transversely circumscribing the sac-like segment. When the connective tissue embracing the neutral buffered formalin fixed vagina was completely teased free, the expo...

Rupture of the gravid uterus is an obstetric catastrophe that is associated with complications that include massive blood loss, hysterectomy, and damage to the genitourinary tract. It is a serious complication that is associated with high maternal and perinatal morbidity and mortality. We conducted a retrospective review of case notes (from 2003 to 2009) to determine the incidence, causes, comp...
