1. Getting older means poorer
sperm report
2. Different hospitals have different
standard. Clinic A finds you're ok but
Hospital B may consider you're not
good. I have this experience. My c6
had no problem in a pre-marital
sperm test 2.5 years ago but have
problem this year. Hospital may
have higher standard, esp. public
ones. My c6 has poor % of normal
form of sperm.
