Looking for answers 😭

Ladies, my husband is very uncomfortable going for seman analyses...which our doctor recommended after getting all positives on my end...he says he will still do bcz we have been trying to conceive for 16 months now..with no luck at all. My questions are;

1.can it still take a while to conceive naturally even if your SO sperm count is perfect?

2. If sperm count is low, could it go to required level without any medical treatment? (Just healthy food and store bought multivitamins may be)

3. Did anyone’s SO ever had a low sperm count and they conceived naturally after all without doing any medical treatments?

I have too many questions and I don’t know who else to ask, so asking my glow family here. Please answer to your best knowledge and I’ll appreciate it.!

I just want to know if it will happen for us eventually even without him getting tested..(he believes if it’s meant to be it will happen regardless of what test say..)
