What caused the zero sperm count? Has there been a retest (in case of lab error)?
Yes it can reverse. nothing is impossible . God has the final say so and if believe you can conceive it doesn't matter what any LAB result or test say Abraham's wife Sarah in the bible was 90 when she conceived her first child if God did it for them ...what make s you different. hold on to FAITH !!!
Has you hubby/partner had vasectomy then reversal?
