I disagree with this. Two really good female friends of mine compete.
Both have taken prop, winny and var numerous times and both had their voices back to the (normal) higher octave. I can't 100% confirm if it was the EXACT same prior but their voices definitely came back.
-------------------------------------------
While the vocal changes may diminish, the data (based on echophonic recordings, laryngoscopy, MRI soft tissue changes, and long term follow up) certainly confirm the assertion these changes are likely to become permanent in many female AAS users.
This is very important for females to KNOW before beginning AAS, because while almost all of the adverse effects of female AAS use are uniformly reversible with TIME and AAS CESSATION, vocal changes may not be.
Moreover once the dysphonia begins continued AAS use not only worsens the existing problem but also increases the chances of permanence! This is particularly true of the 19-Nor anabolics, IME.
