A mamono can become pregnant and actively perform sex at the age of 10, though depending on the species they get pregnant less easy. For more information on reproduction you can use this link http://monstergirlencyclopedia.wikia.com/wiki/Monster_Ecology#Monster_Reproduction_.C2.A0

If you would mate once with say.. an http://monstergirlencyclopedia.wikia.com/wiki/Orc that can reach the age of a normal human, the impregnation chance is 15%

If you would mate with a http://monstergirlencyclopedia.wikia.com/wiki/Baphomet who can live for thousands of years the impregnation chance is 4%

(Don't quote me on these percentages, they are just to give an example.)
