Still trying

Laura
So, me and my hubby have been trying since September 2015, but we're not even sure my husband can have a kid of his own. I already have 2 of my own, 8, and 6. But we're not sure about him, so he's going to take the at home sperm test. Does anyone know how accurate it is? Just really wanna have another baby, a baby with my wonderful husband, but we're worried. Any ideas, advice, would be great.
