Effect of luteal-phase support on endometrial microRNA expression following controlled ovarian stimulation.

abstract：BACKGROUND:Relaxin levels in seminal plasma have been associated with positive effects on sperm motility and quality, and thus having potential roles in male fertility. However, the origin of seminal relaxin, within the male reproductive tract, and the moment of its release in the vicinity of spermatozoa remain unclear...
