Would men's sperm be a significant source of aromatase?

I think so, the study concluded that Leydig cells, germ cells, and seminiferous tubules all showed positive stains for aromatase. But it has to do more with the head (tip) of sperm.

I take that back, it's the tail that has the most aromatase and the head of the epididymis displays estrogen receptors where estrogen synthesis occurs.
