Semen analysis...

Hey all, this is my first time really trying to concieve. I am widowed with 2 children ages 9 and 10. I have met the man i will marry next month and we are currently trying to concieve our first child together. I am taking medication days 3_5 of my cycle and my bf needs to go for a semen analysis on monday. We are so scared his results will prove he is incapable of getting mw pregnant naturally. ... has anyone gone through this??
