I very much doubt that mating a spayed female would reduce her estrus-
like symptoms. Mating causes a whole female to ovulate; ovulation
causes changes in the ovaries; and the changes in the ovaries cause
them to switch from producing estrogen to producing progesterone,
bringing the female out of heat. If the female is spayed and the
estrogen is coming from the adrenals, then mating will not help -- you
can't make an adrenal gland lay an egg. In fact, mating might even
hurt, because it causes a surge of Luteinizing Hormone (LH) from the
pituitary gland, and LH seems to be the hormone responsible for over-
stimulating the adrenal glands in the first place.
