Sperm check kits?

Have any of you ladies been present with these?

My man and I have been TTC and despite all things checking out good on my end, we are still not successful.

He wants to make an appointment with a urologist, but with his work schedule, its been really hard to figure out a set date.

Naturally, I'm over here in tears thinking it's all on me because we both have kids but what if the only time I got pregnant was the last time and my Gyno doesn't know what shes talking about??

So, we've been considering one of the in-home kits to see if his swimmers are active or not.

But I'd rather have some personal feedback before we go down that road.

Let me know if you've had experience in this!!(=

thanks in advance!(=
