McGee (1) and McGee, Juhn, and Domm (a), have shown that extracts of the lipid fraction of bull testicles exert a striking effect on the secondary sex characters of the Brown Leghorn capon.

A successful pregnancy depends on a complex process that establishes fetomaternal tolerance. Seminal plasma is known to induce maternal immune tolerance to paternal alloantigens, but the seminal factors that regulate maternal immunity have yet to be characterized. Here, we show that a soluble form of CD38 (sCD38) released from seminal vesicles to the seminal plasma plays a crucial role in induc...
