You could work with with bull testicle. I would get a pair baptize them in your husband's name. Add some hair from his testicle to the jar with a appropriate scripture about God blessing Adam or another man with many children. Add in rattlesnake root,Sampson root,ginger root an high john root if your familiar with the root. I would also add mandrake root chips if ya can get them. Add high proof alcohol to it or rubbing alcohol an dress a purple or blue novena an burn for 7 days praying that verse an swirling and talking nice to the balls. Keep them up under the bed till you get pregnant then go bury um under a tree.
