Induction of the human sperm acrosome reaction with mannose-containing neoglycoprotein ligands.

abstract：:Sperm capacitation is a maturation event that takes place in the female reproductive tract and is essential for fertilization. A family of phospholipid-binding proteins present in bovine seminal plasma (BSP proteins) binds the sperm membrane at ejaculation and promotes bovine sperm capacitation. Homologues of these pr...

Recently, a product of Leydig cells termed Leydig insulin-like hormone (INSL3) has been proposed as a putative trophic hormone of the first part of descent. Absence of Insl3 in male mice results in bilateral cryptorchidism a...
