welcome to HealthcareMagic
Dilatrend is Carvedilol a beta blocker
and Enap is Enalapril
an ACE inhibitor
both anti hypertensive so the common side effects can be fatigue;asthenia;and Enap is known to cause problems in erection or even impotence
in long term use but there is no direct effect on sperms motility.So if you are planning for a baby you can start no reason to worry about right now about the side effects.
All the best.
