Hoping for an answer!!

Wondering if anyone else has had their s.o take an over the counter sperm test and it be legit? I've had my husband take 3 now (he thinks I'm crazy lol, but I think it's for more of peace of mind) and they've all said he has a high sperm count.. we're going to a fertility Dr on February 3rd and he will put in an order for a sperm test at an actual lab. We've been ttc for almost a year and a half now so I'm really anxious to see how the Dr appt goes.. But would definitely like to know if the over the counter tests are accurate...

Also could someone fill me in on what to expect at our first Dr appt!? Next Tuesday can't get here fast enough!! Thanks in advance :)
