Autocrine regulation of human sperm motility by tachykinins.

abstract：BACKGROUND:Spontaneous abortion is one of the most common complications in early pregnancy. A preventive test to identify women who will experience a miscarriage, even before first symptoms occur, is not established. Activation of maternal immunological tolerance seems to be essential for early fetal development and va...
