Cup half full or half empty

Today my husband had his sperm analysis, he was nervous when providing his sample and wen he showed me his cup (he was slightly embarrassed) he told me not much came out.

It really was a very small amount and now we are worried about the results, do u think he will have to retest?

Can’t imagine the pressure of having to provide a sample on the spot. Has anyone had a similar experience.

Thanks x

***UPDATE

Doctors have asked for another sample as there wasn’t enough to collect conclusive results.
