Endometrial scratching
In endometrial scratching, endometrium is gently “scratched” using a thin catheter which causes immunological reaction leading to increase implantation rate in women with unexplained recurrent implantation failure. Inducing injury to the lining of the uterus in the cycle before starting ovarian stimulation for IVF can help improve the chances of achieving pregnancy. The new lining which grows a...
متن کاملBiomarkers Related to Endometrial Receptivity and Implantation
Implantation is a process requiring the delicate interaction between the embryo and a receptive endometrium. This intricate interaction requires a harmonized dialogue between embryonic and maternal tissues. [Aghajanova et al., 2008; Simon et al., 2000] The three stages of implantation are: apposition, adhesion, and invasion. Apposition describes trophoblast cells adhering to the receptive endom...
متن کاملStomatal Density as a Selection Criterion for Developing Tea Varieties with High Physiological Efficiency
Stomata, the small opening in leaf connecting plant with atmosphere, play pivotal roles in global water and carbon cycles. Stomata regulate the two key important physiological functions viz. photosynthesis and transpiration and thus are crucial for performance of crop species in changing climatic conditions. Although environmental factors influence the density and size of stomata, the genetic c...
متن کاملRole of endometrial immune cells in implantation
Implantation of an embryo occurs during the mid-secretory phase of the menstrual cycle, known as the "implantation window." During this implantation period, there are significant morphologic and functional changes in the endometrium, which is followed by decidualization. Many immune cells, such as dendritic and natural killer (NK) cells, increase in number in this period and early pregnancy. Re...
متن کاملNatural Selection of Human Embryos: Decidualizing Endometrial Stromal Cells Serve as Sensors of Embryo Quality upon Implantation
BACKGROUND Pregnancy is widely viewed as dependent upon an intimate dialogue, mediated by locally secreted factors between a developmentally competent embryo and a receptive endometrium. Reproductive success in humans is however limited, largely because of the high prevalence of chromosomally abnormal preimplantation embryos. Moreover, the transient period of endometrial receptivity in humans u...
