Is PGE2 a Vasodilator?

PGE2 can be injected as a gel into the urethra of the penis to induce erection. It's also important for induced in labour or also can be used in abortion. If there was no fertilisation and there was no feedback, the PGF2 would then tell the corpus luteum to lice or work. And if you turn that off, you don't have prostaglandin. That's right. And it'll close it.
