ADVISE PLEASE Next steps.. azoospermia!

Jessica

So the Dr is recommending a biopsy for my husband who has non obstructive azoospermia. No genetic issues - all tests were normal. Fsh and lh normal. Testosterone 169ngl - Dr said it's on lower side. Has anyone had success finding sperm through biopsy and freezing?? Are there other options - clomid?
