A system for sensing vaginal conditions or for affecting vaginal or body conditions in a mammal. The system includes a portable probe unit and a separate controller unit, both of which include two-way communication devices to both transmit signals to, and receive signals from, each other, wirelessly and in real time. The substantially smooth and sealed outer surface of the cylindrical body of the probe unit has a rounded end and is dimensioned to permit comfortable and repeated insertion into, removal from, and containment entirely within a mammal's vagina. The probe body has a device substantially flush with its outer surface and configured to deliver electrical pulses, receive electrical pulses, sense or sample vaginal conditions and/or deliver medication. Signals to the probe unit comprise control and programming signals acting as a feedback loop configured to start, stop and/or alter activity of the substantially flush device of the probe unit, either automatically or manually, for sensing vaginal conditions or for affecting vaginal or body conditions.
