Brief Answer:
Needs evaluation and investigations

Detailed Answer:
Thanks for your feedback.
Noted that he is using Meloxicam, Clonazepam (SOS), Verapamil and Zolpidem (SOS).
Considering his age of 71, Enlarged prostate can be one reason.
All the above mentioned medicines are known to cause retrograde ejaculation and hence inability to ejaculate. Retrograde ejaculation means ejaculation into the urinary bladder.
This is provided that there is normal erection and there is normal feeling of ejaculation but the actual ejaculate is not coming out of urethra.
Please clarify on these points too.

I would advise the following in such a condition.
- Ultrasonography for genito-urinary system, prostate in particular.
- Blood: routine and PSA (Prostate specific antigen)
- Per-rectal examination for the prostate.
- An opinion of an Urologist and further investigations and treatment as per the cause found.

I hope this answer helps you to get an early and proper diagnosis and management of the said problem, please feel free to ask for further relevant queries if you feel that there is a gap of communication.
