Brief Answer:
Wait for a week or two before checking testosterone levels.

Detailed Answer:
Hello dear and thank you for asking again.

Having no erections in the morning may signify erectile dysfunction caused by drugs (antidepressants), low testosterone, obesity, diabetes, etc.

You can wait for a week or two, trying to minimize stress and relax hoping that this will resolve by itself.

If it doesn't seem to get better you may check testosterone levels, cholesterol, and blood sugar.
