Is there a connection between two homeopathic medicines given to cure erectile dysfunction, and premature ejeculation? Where any medicine may give good effect in erection but negatively affect the ejeculation time i.e. reduces the sex timing/duration and vice versa. How important it is for a physician to choose the right medicines? Currently the patient is on the medicines named  Lycopodium, Agnus Castus, Damiana, Nuphur Lutea, Ustilago Maydis, Nux Vomica, and Phytolacca Berry tablets. Your valuable advise is worth a lot.
