This spell enables the caster to increase the fertility of the target. The target may be either male or female. The fertility of a character may be calculated as follows (as per The Carnal Knowledge Guide). A target's normal fertility equals the base chance plus constitution modifier, determined from the table below. If both participants are "fertile" at time of copulation, pregnancy results.

	Race	Base Chance	Constitution	Modifier
	Dwarf	22%	01-03	-6%
	Elf	13%	04-06	-4%
	Gnome	20%	07-09	-2%
	Half-Elf	54%	10-12	+2%
	Halfling	50%	13-15	+4%
	Human	77%	16-18	+6%

Successful casting of this spell increases a character's fertility by 5d6%. In addition, there is a probability, equal to the level of the caster (1% per level), that successful conception will result in multiple births (roll 1d20: 1-17 twins, 18-19 triplets, 20 quadruplets). Multiple castings of this spell on the same individual (while the first is still in effect) automatically fail, as does casting on a pregnant person. This effect lasts through the target's next copulation; thereafter, the target's fertility returns to normal. Fertility can also be countered magically by spells such as dispel magic, infertility, or wish.
The reverse of this spell, infertility, destroys the target's ovaries or testes, and automatically results in a failed attempt at conception (assuming that the target did not save versus spells). The target remains infertile until a successful dispel magic is cast upon him or her, followed immediately by a regenerate (the former dispels the magic, the latter repairs the physical damage).
Note: fertility cannot counter the effects of infertility, but if the target is already under the effect of the former, he or she receives a +1 bonus to save.
This spell and its reverse may also be cast upon animals (eg., on horses). The DM should adjudicate the animal's initial fertility based on type, breed, and quality of animal.
The spell can affect up to one creature for every 3 levels of the caster, unless the priest worships a god of fertility, creation, death, or destruction, in which case the priest can affect one creature per level. Priests who worship fertility or creation gods cannot cast infertility. Priests who worship gods of death or destruction cannot cast fertility.
The material components for fertility are the caster's holy symbol and a seed from any plant (the seed is not damaged). The caster's holy symbol and the ashes from a handful of seeds are required for the reverse (the ashes disappear during the casting).
