study of endometrial perfusion in unexplained infertility

ABSTRACT

Background: Infertility in itself represents a wide spectrum of disorders explaining the inability to conceive. Series of investigations are required to depict the potential cause of infertility, yet there exist a small percentage [10 -25%] of couples in which no obvious cause is delineated. these groups of patients are classified as 'unexplained infertility. The endometrium has dynamic features cyclical growth, desquamation and regeneration. Its main function is to provide the possibility of the time-limited support of implantation of the embryo for further development. Most part of the menstrual cycle, the endometrium is resistant to the embryo but acquires special receptive properties in a limited space and time interval of the luteal phase, known as the ''implantation window''
